Tool 170i500L006A

Titanium and nickel alloys generate heat that kills edge life faster than the spindle can compensate with speed. The TiAlSiN coating on this 170 Series end mill creates a thermal barrier that keeps the cutting edge cooler during interrupted cuts in demanding aerospace materials.

Seven flutes distribute heat generation across more cutting edges while maintaining chip evacuation in steel through nickel-based superalloys.
The 0.015" corner radius strengthens the cutting edge against chipping when entering titanium work hardened layers or interrupted surfaces.
Heat resistance becomes critical when table feeds climb above conventional ranges.
This geometry works in materials from 4140 steel through Inconel 718.
Requires spindle rigidity and consistent coolant flow.
The coating extends tool life in applications where uncoated carbide would dull within minutes of sustained cutting.
