Lock tooth milling cutter head

T2139 ball finish milling cutter

Anti-vibration design reduces blade wear

Constructed from 42CrMo alloy steel for enhanced rigidity and higher hardness.
The curved head effectively suppresses vibration, minimizing blade wear.

Quenched and tempered for durability and deformation resistance

Vacuum quenching process enhances hardness and concentricity, improving machining results,
boosting efficiency, and extending tool shank lifespan.

Precision-fit inserts with zero gap

Triangular positioning combined with offset screw fastening ensures seamless,
gap-free alignment between insert and shank. Securely locks the insert to prevent
tool chatter during machining, delivering superior results.

High concentricity ensures stable clamping runout

Dual-end locating center holes on the tool shank, processed with high-precision
center grinding machines, guarantee coaxial alignment between the shank diameter
and cutting edge diameter, achieving superior concentricity.
