When it comes to the MS-20,I think I touched on it a little bit earlier,we've got a new way of manufacturing the inserts ,so this then gives us more accuracy within the inserts ,but it also gives us a more secure cutting edge ,so a stronger,more predictable cutting edge. As a concept ,it's a true 90 degree concept,so if we want to do repeated shoulder milling or repeat down a wall,we can do,because it's 90 degrees. We have a new insert design interface,so the insert sits a lot secure within the pocket. We have optimized geometries to suit all materials. We have better chip control,so if you look at the pockets,the chip area of the pockets ,especially in ISO-S and M materials where there can be a problem,we're able to get rid of the swarf ,the chips a lot easier,so we're not recutting.
