Literal statement:
The structure of Iphone 8 is used 316L stainless steel. This material is more difficult to cut than the 304 stainless steel. Especially the suppliers of Apple Inc. use MIM processing of small accessories, the previous endmills has been unable to meet their needs. Our team has adopted special ultra-fine grain tungsten carbide, special spiral angle, special cutting edge design and Nano AlCrSinN, the product has a perfect sucess, and has won high praise from FOXCNN and MiYa.
Features:
Suitable for rough milling, semi-finishing and finishing of stainless steel (<280HB).
Design for the small depth/large width in face milling, large depth/small width in side milling, less than 0.3D in shallow slotting.
Water soluable or oil based are the best cooling methods.
