Advantage:

1. Large chip flutes can effectively ensure smooth chip removal and improve machining efficiency
2. Nano-coating on the cutting edge, nano-coating can reduce the loss of the tool, the tool is more wear-resistant, reduces the number of tool changes and also has the function of heat insulation
3. Cemented carbide
Using fine-grained tungsten steel base material, it has higher hardness and better bending strength, the tool is more wear-resistant, not easy to chip and break, and has a long service life
4. Easy to operate chamfering
The chamfered shank layout is easier to clamp.
