Tool 170i625L006A

Seven flutes distribute cutting forces across more edges, reducing individual edge stress while maintaining aggressive feed rates in demanding alloys.

The 170 Series handles steel, iron, titanium, and nickel alloys where conventional endmills bog down or wear prematurely.
TiAlSiN coating adds thermal barrier properties that matter when cutting generates heat faster than the workpiece can dissipate it.
The aluminum content in this coating maintains hardness at elevated temperatures while the silicon contributes to oxidation resistance.
At 5/8" diameter with seven flutes, this geometry requires consistent engagement and a setup that won't flex under cutting forces.
The R0.03" corner radius strengthens the cutting edge compared to sharp corners while leaving a controlled radius on internal features.
Works best in slotting and profiling operations where you can maintain steady chip load per tooth.
