However, in fact, the two are very contradictory. If the tool is sharp, the cutting angle must be increased, but when the front angle is too large, the tool strength is weakened, the heat dissipation condition is poor, and the tool durability is lowered. A double chamfering tool that maintains a large front angle and a high strength is now described. This tool is both sharp and wear resistant and efficient. Double chamfering cutters are shown. Γ_0 and γ_(01), γ_(02) respectively represent the former
