 How to distinguish hardware tools of spiral angle end mill to enhance competitiveness

How to distinguish hardware tools of spiral angle end mill to enhance competitiveness

The larger the helix angle of the end mill is, the longer the contact length between the workpiece and the cutting edge is, which can reduce the load on the cutting edge per unit length, thus prolonging the tool life. However, at the same time, the cutting resistance will increase. Therefore, it is necessary to consider the use of a tool holder with high clamping rigidity. For the stainless steel with low thermal conductivity and great influence on the edge heating, the cutting edge is hard to cut
