100R Series

Tool 100Rm040LA

Roughing heavy sections means heat, wear, and tool life become the limiting factors. You need every advantage when you're hogging out 4" worth of material. The 100R Series handles this with chipbreaker geometry that fragments chips before they can pack the flutes or conduct heat back to the cutting edge.

The TiAlSiN coating adds another layer of thermal protection.
Aluminum content in the coating creates an oxide layer at cutting temperatures, which acts as a thermal barrier between the tool and workpiece.
That matters when you're running aggressive parameters in steel, iron, titanium, and nickel alloys.
The 0.1" chamfer strengthens the cutting edge against impact loading while maintaining aggressive cutting action.
Surface finish will require a follow-up operation, but material removal rate is what counts here.
