100R Series

Tool 100Ri125FA

Small diameter roughers break. That's the reality when you're trying to hog material with limited tool mass to absorb cutting forces. The 100Ri125FA takes a different approach. Four flutes spread the load across more cutting edges while chipbreaker geometry prevents chip packing that kills small tools.

TiAlSiN coating adds wear resistance without building up thickness that would dull the chipbreaker action.
Heat from high-speed roughing operations stays in the chip, not the tool.
The 0.004" chamfer reinforces the cutting edge against chipping while maintaining the aggressive bite you need for steel, iron, titanium, and nickel alloys.
This isn't a finishing tool.
Run it hard to remove material, then switch to a finisher for surface quality.
The geometry does the work.
