100R Series

Tool 100Ri250LA

Small diameter roughers take a beating. The chipbreaker geometry that works on larger tools can overwhelm a quarter-inch cutter if the features are too aggressive. The 100Ri250LA scales the chip-breaking action to match the tool size. Enough disruption to prevent chip packing without compromising the edge strength you need at this diameter.

The TiAlSiN coating handles the heat buildup that comes with smaller tools running in steel, iron, titanium, and nickel alloys.
Higher speeds generate more heat per unit of cutting edge, and the coating's thermal barrier properties keep that heat in the chip instead of migrating into the carbide substrate.
The 0.006" chamfer strengthens the cutting edge against the impact loads that come with interrupted cuts and entry conditions.
This isn't a finisher.
It clears material so your finishing tools can do their job.
