100R Series

Tool 100Ri156LFA

Small diameter roughers walk a line between aggression and breakage. The 100Ri156LFA handles that balance with TiAlSiN coating over a 4-flute chipbreaker geometry. At 0.1563" diameter, you need the hardness and heat resistance the coating provides when pushing material removal rates in steel, iron, titanium, and nickel alloys.

The chipbreaker edges segment chips before they can wrap around the small tool diameter and cause problems.
TiAlSiN coating extends tool life by managing the heat buildup that kills small end mills.
The 0.004" chamfer strengthens the cutting edge against the kind of impacts that snap delicate roughers.
This isn't a finishing tool.
It removes material fast while the coating and geometry handle the thermal and mechanical stress.
Run it hard, then switch to your finisher for surface quality.
