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 AlCrSiN, the product has a perfect success, 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.

Attention:

1. Make sure work piece and machine are stable and use a precision holder.

2. Please adjust the speed,feed and cutting depth according to actual cutting conditions.

3. The milling conditiongs are for an End mill where the tool overhang length is less than 4*D(mill dia). When the tool overhang length is longer, please adjust the speed,feed and cutting depth.
