Tool 150i500L006A

Built-up edge formation kills surface finish in steel. The 150i500M015A addresses this through five flutes and TiAlSiN coating working together.

Five flutes distribute cutting load across more edges, reducing individual chip load at equivalent feed rates.
This keeps cutting temperatures down while maintaining productivity.
The TiAlSiN coating adds oxidation resistance and reduces chemical affinity with steel, iron, titanium, and nickel alloys, which means less material welding to the cutting edge during operation.
The R0.015" corner radius strengthens the cutting edge compared to sharp corners while still producing acceptable surface finish for semi-finishing operations.
This geometry balance extends tool life in harder steels where edge chipping typically limits performance.
Half-inch cutting diameter handles mid-range pocket work and profiling applications effectively.
