Tool 190i750M060A

Finishing hardened steel at three-quarter inch diameter puts real stress on cutting edges. The 190i750M060A spreads that load across nine flutes to keep each tooth engagement minimal.

TiAlSiN coating handles the heat that builds up in steel, iron, titanium, and nickel alloy applications.
The aluminum content in the coating creates a barrier that lets you push speeds higher than uncoated tools allow.
Nine flutes demand high RPM to maintain proper chip load per tooth.
The R0.06" corner radius strengthens the cutting edge against chipping while maintaining the finish quality you need in hardened materials.
Sharp corners fracture under the interrupted cuts that come with finishing operations.
This radius gives enough strength without compromising surface quality.
Requires rigid setup and adequate spindle speed.
Not designed for roughing or heavy material removal.
