Integral metal ceramic ball blade milling with two edges and two edges, high hardness and high smoothness mirror steel parts R1-R8

High-hardness hardened steel and mold steel curve finishing requires ultra-high tool performance. Ordinary carbide end mills are prone to high-temperature chip adhesion, edge passivation and obvious tool marks, failing to achieve mirror finish. Made of premium integral metal ceramic, this cutter has lower friction coefficient, higher thermal stability and better oxidation resistance than traditional carbide tools, making it the best choice for mirror finishing of hard steel.
