100R Series

Tool 100Rm100A

Large roughing cuts generate serious heat and wear. The 100Rm100A handles both with TiAlSiN coating that extends tool life in steel, iron, titanium, and nickel alloys by maintaining hardness at elevated temperatures while reducing friction along the cutting edge.

The 4-flute configuration balances material removal rate with rigidity on this 10" diameter tool.
Chipbreaker geometry interrupts chip formation before long stringy chips can wrap around the workpiece or bind in the flutes.
That 0.15" chamfer strengthens the cutting edge where it matters most, preventing the micro-chipping that kills tools in interrupted cuts.
This isn't a finishing operation.
The surface texture reflects the aggressive parameters these tools are designed to handle.
Run the rougher hard to clear material, then switch to your finisher for surface quality.
