Hello, my name is Ben Lodge,I'm the Solid Round Tools Product Manager for Sandvik Coromant in Sales Area Southwest Europe and today I'm joined by Barry. Yep, thanks Ben, my name is Barry Cahu,so I'm the Product Solution Specialist for Rotating Indexable Products within Sandvik Coromant. Welcome to this Drilling Knowledge Session. Firstly, we start off with safety. Safety is our top priority at Sandvik Coromant,so please ensure that you're watching this video in a safe environment. So Barry, today we're going to be talking about drilling ,so what can we expect in today's session? Well, we're going to be talking about many different things, different products, myself and you. We're talking about,you know, what products to apply,you know, because at Sandvik Coromant we've got many different products to do many different things, and it's all around picking the right product for the application that we've got in front of us. We talk a little bit about chip control and the chip formation and how we can overcome certain obstacles within that chip formation to make sure we've got a good whole quality. So, I suppose the first thing is to look at the different types of holes and we can see here a quite wide variety of holes. Everyone sees holes quite simple application maybe, but not always. You know, we can see there all the different typical types of holes that are available to be manufactured during the drilling process. So there we can see, you know, holes with clearance for screws, screw threads, countersunk holes, obviously precision holes, holes for pipes. So predominantly looking at heat exchanger applications, holes to form channels, holes for weight balancing, and then obviously deep holes and coolant holes that we might encounter during applying these products. Yeah, like say Ben, there's lots of different applications of drilling a hole, but they've all got their own different tolerances, different needs to what that hole is actually doing, that operation for. Yeah. And I suppose we should start at the beginning, maybe a bit of an explanation regarding the drilling process and how it works when it comes to drilling. Yes. And I guess, especially when we're looking at either exchangeable tip drills or solid drills, when we look at the surface speed, the surface speed on the outside of the drill is always the same, let's say. But as we get to the centre with any drilling process, then we're getting zero surface speed at centre. And that's where, obviously, a good strong point is needed for that operation. And of course, with an exchangeable tip drill or a solid drill, you've got two flutes as such, whereas an indexable, really you've only got, OK, you've got physically got two flutes, but they overlap, meaning you've only got one. So it's a lot more productivity wise if you're using this type of solution. And I suppose that's where the challenges are. You know, when once we start to get to the centre, we need to control the heat, everything else that's happening in the centre, because that's where we can see a breakdown in the in the chisel of the drill itself. And I guess you mentioned the chip chip control. I guess chip control is is the ultimate, I guess, when we're drilling any holes. If we don't get good chip control, we're not going to get a good hole. We're not going to drill a hole in some cases as well. So absolutely. And that's why it's really important, because obviously, when we're drilling or in drilling applications, we need to ensure that the chips are coming away from the cutting edge, that we're not recutting those chips, that we're not getting them jammed within the flute, because ultimately we've got an enclosed area. And that enclosed area is getting deeper and deeper wherever we're in the drilling application. So, you know, if you're going to have problems, you know, one times D, then you certainly going to have problems when you're getting deeper. So making sure we've got that correct chip, correct chip formation is imperative during the drilling process. I guess the main, the three main things are, you know, with chip evacuation, poor hole surfaces, finish, tool breakages and dimensions as well. If we don't get that chip control right, then the dimension of the hole may not be right either. So I suppose now we'll have a little look about the chip formation and chip breakages. And as we can see there, you know, there's a lot of things that influence the chip and how it's done itself. So we can see that, you know, the material, the chip breaker, obviously the cutting speed and feed, the pressure and the direction of coolant. Again, really important factor. And, you know, the vibration, we need to ensure that we've got that stability within that product, not only in the cutting tool, but also in the material itself and the fixturing. So I suppose as we look at these chips, different kinds of chips here. So we can see we've got the three examples with the indexable, insert drills, the exchangeable tip drills and the solid drills. And, you know, we can see that we've got the excellent, the acceptable and the unacceptable of risk of jamming. And, you know, the main thing being the length, the size of the chip that's going to cause us problems. As we spoke about that enclosed area, the bigger the chip, the bigger the problem that we're going to have. So I suppose if we have these issues, these different kinds of chips, then we need to look at the remedies. And this is where we can see how we can improve the chips themselves. So there we've got the long connected chips. So if we were getting something like this, then we'd look at increasing our speed to try and get a shorter chip. As we look at the thick and the rough chips, obviously reducing the feed, increasing the speed would help us with that. And then as we look at these thin and open chips, this is where we want to try and increase the feed, certainly to try and get them a little bit more enclosed than they were previously. And then lastly, these long chips, you know, here we want to be increasing the feed, increasing the speed to help us try and resolve that issue that we've got. Because we want to be in that excellent area, nice, short, repetitive sized chips that we're going to have with the drilling process. Yeah. And I suppose not only with the material, I suppose different materials have different challenges as well when it comes to the different applications of drilling. Yeah, definitely. I mean, in most cases, I so P or steel material, in most cases, we don't have any issues with swarf or chip evacuation. But we still, there are some ISO P materials that are long chipping materials. So that can cause us as problems. And what we would need to do then is look to increase the speed, the surface speed and decrease the feed rate. And hopefully that will overcome any of those long chipping materials that we have. And it's a similar story with ISO M. So your stainless steel areas, particularly, you know, the long chipping stainless is, your duplexes, super duplexes, materials like that. Again, we need to look at increasing the feed rate to try and break those chips up a little bit if we can. And then a similar story with your ISO S or more particularly your nickel based materials. Then we need to be looking at increasing that feed rate to try and get that long chip chipped and shorter. And I suppose in that area as well, coolants are really important factor. When we're looking at HRSA materials, we need to make sure we're getting those coolant properties in there. Yeah, as we touched on there, we don't want to work hard on the material any way, shape or form, especially, like I say, especially in those materials. And that's what you do get or you can get work hardening. And so, like you said, Ben, coolant is a must for those certainly those types of areas and applications. Yeah. So now if you look at some factors and how we decide on the drills, I suppose the first one that we're going to look at is achievable hole tolerances and, you know, different kinds of products have different achievable tolerances for the hole. Yep. Yeah. So if we look at if we start off with the solid carbide drills, they can achieve a much tighter tolerance. You know, we're looking at IT6 as the the the the the small the smallest tolerance. Let's let's let's say that you can achieve going up to IT9. Then if we move over to the indexable tip drill, we're looking at IT9, IT10 depending on how we apply it. And then an indexable drill, a tip drill is is a lot bigger and you can get a better tolerance if you start using pilots and things like that. Yeah. So yeah, if you want a much tighter tolerance, then you'd go for the solid carbide creeping up to the indexable tip drill and then indexable drills themselves. And I suppose there's lots of different options when it comes to the drills. You know, we can see here the customized products, then looking at chamfer drilling, but also the step drill or step chamfer product. So there's lots of options available to us within the standard portfolio to satisfy kind of a one shot application as well. Yeah, if you want to drill a pre hole for a tap, for example, and you want to have a chamfer, then we can we can use customized tools or tailor made to maybe get a step and chamfer on on multiple drills, whether they be indexable or solid carbide. So now I suppose we have a look into how we select the drill and we can we touch on it a little bit here, I mean, already, but we can see that the three different offers when we look at the indexable insert drill, the exchangeable tip, and then obviously the the solid carbide products. And, you know, looking at that, you know, we touched on the diameter tolerances, obviously the other factors as well within there as well, like depth capabilities will be one factor. Yeah, when it will maybe a solid carbide, we can go up to 30 times D in some cases, which obviously is quite difficult to achieve with other products. Definitely. But obviously, they all have their own benefits for each different one. Yeah, so if you wanted medium to large diameters with a fairly open tolerance, let's say, then maybe you'd use an indexable drill for that kind of area. If you're looking at medium diameters, and you want in something a little bit tighter tolerance, a lot more accuracy, better surface finish, then you'd look for an exchangeable tip drill. And also in that area, you solid ground tools as well or a solid drill you could use as well, but even smaller diameters, you're able to achieve. I mean, some of the products we have, you'll know better, but certainly in the solid range, we can we can machine quite small diameters. Yeah, absolutely. I mean, point zero three, we can have as our smallest drill for micro drilling. So yeah, we've got a quite considerable range, obviously down to the smaller diameters. Yes. And I suppose as we're looking at process considerations, you know, we've talked about the smaller drills where it's really imperative, but for all drilling applications, we need to make sure that we've got a good concentricity of the product, you know, certainly for looking at the non rotating applications, lathe applications. Yeah, yeah, definitely. I guess it's not as vital in rotating areas, although, you know, it does have an impact if the tools running out for sure. But certainly in non rotating in lathe applications, we need to make sure that our drill is running on centre. If you're using an indexable tip drill, an inserted drill, let's say, then the peripheral tip needs to be in line with the X, generally in the X axis of the lathe to get a true hole at the right size as well. So yeah, it's vitally important that these drills are on centre for sure, especially in LA. And obviously in rotating applications, we spoke out about it as well, you know, ensuring we've got a good run out, that we've got a good accurate tool holder is really important. You know, for us, Corachuk 930, we're not really going to talk about it too much today. But, you know, it's a really important product when we're looking at the accuracy that we'll have, certainly when we're looking at a concentricity of a rotating application. So now I suppose we should really have a little look at some of our latest products that we've launched. So I'll kind of hand over to you to talk about the DE10. Yep, no problem. Thank you, Ben. So DE10, as Ben said, this is one of our latest products in drilling, in rotating indexable. So this is an exchangeable head tip drill, what we spoke about earlier on. So for us, it's very new on the market. And when we introduce products, it doesn't matter what product they are, whether they be drilling, milling, end milling, whatever they may be. We do a lot of testing with our products, as you know. And the feedback from the testing that we have done, whether they'll be in a lab or more importantly, our customer sites. So real life scenarios on real life machines, the actual, the results that has come back from using DE10, that it's around 40% more increase on tool life, compared to what we're up against with our competitors and our existing products as well. And that in turn, helps us get a reduction in CO2 with our sustainability targets that we have. So we're able to run the drill a lot harder, penetration rates are a lot faster, and we're able to have that drill in the machine a lot longer without having to change an insert. So when it comes to successes with drilling, of course, what are the main successes? Of course, tool life is what we all want. We all want tool life in the drilling process. And with DE10, we have this optimized geometry now to cover all materials, which we'll talk a little bit further on. We've got robustness, and I think that's the biggest thing with this product. This is a very robust drill that we've got. We're able to achieve the whole quality that's needed, depending on the application that we're looking at. Productivity for sure, because we're able to increase with the high penetration rates that DE10 offers. And no pilot drill as well. So some drills, we have to use a pilot, but with this product with DE10, we don't have to use a pilot. We're able to go in drills, the depths of up to eight times D, and in the future, 12 times D without pilot. And why is that then? I guess, why is that? So really, we've got this new painted design with DE10. So this head locks into the drill body. So the drill tip locks into the body, rotates, and it's a really good connection. We've got these angled faces that gives us that more security, more reliability. But also, we've got like a little tang within the head that makes up to the body. So the drill cannot pull out either. So ultimately, we've got a lot more strength with this work. We've also got, because of this new painted design, a lot more drill tip changes. So any tool has got shelf life. You can only rotate or index and insert so many times before you have to start looking at replacing the drill body in this case. Whereas with this design, we're able to get more drill exchanges without having to buy a new drill. So very good when it comes to that. Very secure, very reliable. And I suppose that will offer a cost saving maybe over some other competitors, because you aren't having to increase that frequency of buying your drill bodies. You know, consuming less when it comes to that. Yeah. And on that point there, Ben, when you say consuming less with D10, we have a geometry M5 geometry, and that is suitable for all materials as well. So if you're machining different components, different materials each day in your machine shop, then you're not having to buy separate drill tips, other than the diameter, of course, for different materials. You're able to use one geometry for all materials. And providing you stay within the recommendations and each of the tools when they do arrive, the drills when they arrive in your workshop, they will come with some information on recommended data for certain materials, minimum and maximum. Providing you stick within that area, then the drill will work in a good way, in a good way. So when we're looking at applications for D10, of course, any high volume drill holes, that's what D10 is made for in all industries, really. But then if you look at components, you know, heat exchanger plates, shafts, pumps, construction steel frame beams, very good on that product. But for any anywhere that's drilling a lot of holes, then D10 would be a good product. But it's not just capable of drilling a straight hole, let's say, in a straight surface. We can go on inclined or surfaces. We're able to do cross holes, through holes, many different things. Providing you reduce the feed rate on entry in these difficult areas, then you won't have a problem with the drill. If we look at the assortment now for D10, so we are starting at 9mm, up to 17.9mm in diameter, 3 and 5 and 8 times diameter in drill length. Future releases for D10 will be up to 12 times D, without the need of a pilot as well. And also, around that time, we will introduce a flat bottom. So, if someone wants to drill, rather than having the 158 degree point, you want a flat bottom, you can have that in D10 in the future. And of course, we've got this M5 geometry, two different grades, which covers all the materials, and we'll touch on that now. The geometry, the M5, one geometry, making it easy for us, as Samvik Karaman and our customers to pick, but two grades. So, if you want more wear resistance in your drilling operation, then maybe 43, 34 would be the grade for you. And that's the first choice for steel, but it will cut all the other materials in a good way. If you need something a little bit more tougher, then grade 23, 34 would be for you. It's a little bit sharper as well, so certainly sharpness is what you need in ISO S and M, so your stainlesses and your heat resistance. And maybe you'd pick that grade. But again, like I said, both grades will cover both materials, no problem. So I suppose there you've got two versatile grades that maybe work or perform better in certain areas, first choice. Yeah. And then we've got a drill, you know, three to eight times D, different surface entries, exits. It sounds a really versatile product that we're launching within this area. It is versatile and easy to use. It's really easy to use. Providing you run it at the data that we recommend, which is quite readily available, then you won't have a problem with the drill in all materials. If we look at the actual mounting of the tip now, or the head. So each drill, when you buy or purchase a drill, each drill will come with this little stainless steel key. And that key is the device, if you will, that locks the drill tip into the drill body. And you'll notice from the graphic there that it's double sided. So one drill key will cover all that drill range. So from nine to 17.9 diameter, one key will cover that range. And that's the item that comes with the drill. If you want something a little bit more fancy, some people do. We do offer a, a, another type of mountain. So it uses, utilizes the same stainless steel key, but it comes with a plastic cover. The plastic cover obviously goes over the stainless steel, and then you have different heads to suit the different diameters so that you're able to index the inserts in a good way. So does that give us more accuracy when we're locating the key onto the head to make sure we're central? Well, it gives you more of a guide because of you've got, you've got these collars that are going over, over the drill tip. And because it's a see through or clear plastic, you're able to see what's going on. So you're not mislocating the key to the tip. So now I'd hand over to you, Ben, we're going to talk about Coradrill Dura 462. Yep. Which obviously you know a lot more than I do with this product. Cheers, Barry. So Coradrill Dura 462, as you said, Barry, a new launch for us in versatile drilling. This is a product that supersedes our 460 drill, which you've had for a number of years now for the versatile area. So again, a drill for all materials. You kind of touched on it a little bit when you were talking about the DE10. And it's a very similar story when we're looking at the Coradrill Dura. You know, this is a product for multi-material applications, similar in three to eight times diameter. But this, you know, complements our Dura family. You know, a number of years ago, we launched our Coramil Dura. And now we're seeing the Dura family taking shape. So for us now, Dura is our versatile range when it comes to Solid Round Tools products. Yeah, I'm hearing a lot about Dura in the market from both internal people and our customers as well. And the end mills that you talk about. And now this new drill. People are really saying that, you know, you apply it and it works in both areas. And this is the thing, you know, you touched on it before. You know, we can have trust in our cutting data. A lot of work is going into making sure that we're in the right areas when it comes to the cutting data for both the Coramil Dura, which has been a fantastic product for us and going forward with the Coradrill Dura as well. So, you know, we've got a really good product line taking shape here. And as we look at the drill itself, you know, there's very few differences over the 460 when it comes to the design. But the main area that we've seen the improvement is when we're applying our new coating. So Zetivo 2.0. And here we can expect, you know, tool life increases in some cases up to 100% increase in tool life from where we were previously with this product. And not only that can we see increases when it comes to tool life, but because of the new coating, we're also seeing increases in our productivity as well. So we're making a big change with this product from where we were previously. And, you know, we can be confident because of this new coating of the performance levels that we can have. Yeah, we seem to be using now this Zetivo coating, like you say, this new PVD coating on a lot of our products, obviously on the D10 as well. We've seen the new Dura drill 462, but we also use it on milling products and we've seen vast improvements on everything that we've we've applied it to. Yeah, absolutely. It's been a really big step change for us. And, you know, this is about us, Samit Coromant, developing our own coatings for applying these products. So, you know, we've got a new process for ourselves, a new design of coating that we're seeing the advantage of now. And as we look at the drill itself, as I said, it's very similar to the 460 that we've seen before. So we can see that this large fluke shape for the volume. We've got the single margin to help reduce the heat generation, you know, and improve the stability. The versatile point geometry, you know, the points really important when we touched on in drilling applications. We need to make sure that we've got a point that will work in a good way to help reduce those forces that we might see as we're getting down into the center. And certainly it's an important factor when we're looking at the cutting data that we're looking at and the heat generation that we might have from the drilling application itself. And as we look at the applications that we can use it in, it's a very similar or same picture that we saw with DE10, where we can look at, you know, these angled surfaces, stacked drilling, cross holes, and obviously radius surfaces as well that we can go into. So here we're looking at 3 to 20 millimeters in diameter up to 8 times D. And that's in a varying industry segments that we can apply them in. So I'd say for us, there isn't really any restriction when it comes to the corridor of what it can be applied in from a material or an industry segment. So, you know, we've touched on it before, but very versatile, you know, multi application, multi material drill. You know, there's nothing we can't do with this drill. No, for sure. And also when we take into account, we've also integrated our micro drill range into the corridor, Dura range. So here we can see that not only we've got the drills above three millimeters in diameter up to eight times D. We've also got drills below three millimeters in diameter. So point zero three to three millimeters up to six times D in micro drilling applications. So, you know, we've got a really wide range of products now going all the way from point zero three up to 20 millimeters in diameter. Okay. Yeah, that's very small. Yeah, I would like to be loading that in a micro drill. It's a good eyesight to see and that's for sure. So, you know, now there's for us, we're seeing a really good formation of a drilling range. And, you know, I think our products complement each other depending on the requirements that there is for the customer and the holes that they're manufacturing. And as we look on to some of the other things that we can offer when it comes to the corridor Dura recondition is a really big factor. Always with solid round tools, but certainly when we're looking at corridor Dura. So utilizing our reconditioning service will give the as new performance that we see with a new drill. Obviously, the importance of using our reconditioning service is the reapplication of that Zativo 2.0 coating. It can only be applied by ourselves. But obviously then that can offer a cost reduction for our customers as well by utilizing reconditioning. Yeah. And I guess if that can drill can be reground, reconditioned in the same way that it's been manufactured originally and you can offer the same performance, then wow, that's a game changer. Yeah, for sure. And the cost savings are there. And as well as, you know, recycling, you know, sustainability is a massive thing for us and our customers. So being able to recycle our products after it's used its life up from a reconditioning point of view is really important as well. Yeah. So now I suppose we should look at for both products, you know, cutting data, you know, finding information about those products. And, you know, we've got a number of apps that are available to us that we can utilize for that. Yeah. And those apps, you know, machining calculators, toolware, analyzer, iFind, you'll be able to find these apps on your app store. But we can get a lot of information from these from your phone, you know, from your phone, a lot of information. So picking the right tool for the application, but not only just picking the right tool, but picking the right cutting speed, the right data for that particular material that you may be machining. So there's a lot of information within the app store or the apps that we have for some of it, but also on our web as well. So if we look at Corea Plus tool guide, for example, so if you're on our web, put in the drill that you're wanting to use or even just the application that you're wanting to do. And then we will give you real life cutting data, offer you the drill, tell you how long it's going to last, you know, how many meters it can drill. Lots and lots of information there when it comes to Corea Plus tool guide. And I'm right. It also offers the power torque that's required to drill the application. So yes, that can then be a good factor depending if your machines capable of using that product as well. You're able to go into that type of level as well. I guess if you want to, you can actually put your machine in there as well with your power, your torque that is available on your machine. And it will tell you yes or no, that that that drill can do that or that product can do that or it can't do that, which is more important. So I suppose then Corea Plus tool guide can really tell you which drill is going to be best for you. Yes. And that's based on real life scenarios as well. So the data that is given to you once you go in and edit your application area, it's based upon real cutting data that's happened, not just in a lab, but at machine shops all over the world. So I suppose that's kind of only the tip of the iceberg when we look at Corea Plus tool guide. There's also a lot of other things that we can do as a company and other services that we can offer to support customers needs as well. Yeah, yeah. I mean, obviously there's the yellow coats, myself and you and many others of our local guys in the market will always go and support for cutting data. We have lean services now within within our portfolio, Sandvik Coroment. We have online support. Of course, we have online support where you can find information on our products. We have technical training. So we offer Sandvik Coroment offers technical training, whether it be here in one of the many centers that we have globally or at your your site, your area. So if you didn't want to come away from your production environment, then we'll come to you and do whatever training that you want. And as well, like I said, we've got these centers here. So we do many different trainings, many different events, customer visits here. We do a lot of a lot of projects as well, engineering projects. So for example, if we've got a customer that's machining a particular application and they want some assistance with and they don't want to break down their production and their machine shop, then we can bring it here to this center or many of the centers and try and work around that scenario that they have and offer them a solution without breaking down their production. So a lot more than just a tooling supplier. Correct. Yes. Excellent. So that concludes our session for today.
