100R Series

Tool 100Rm050A

Heavy cuts in hard materials generate heat that kills tools fast. The 100Rm050A handles this with TiAlSiN coating that forms a protective aluminum oxide layer at cutting temperatures. Heat becomes your friend instead of your enemy.

The chipbreaker geometry along all four flutes fragments chips before they can weld to the cutting edge or pack the gullets.
This matters more on a 5" diameter tool where chip evacuation distance increases dramatically.
The 0.1" chamfer strengthens each cutting edge against the impact loads that come with aggressive roughing parameters in steel, iron, titanium, and nickel alloys.
You're not chasing surface finish here.
You're clearing material fast without tool failure or workpiece movement.
The coating extends tool life in interrupted cuts where uncoated carbide would chip or crater.
