100R Series

Tool 100Rm060A

Heavy roughing cuts generate heat. More heat than most coatings can handle long-term. The 100Rm060A carries TiAlSiN coating specifically because it maintains hardness and lubricity when cutting temperatures climb past what TiAlN or TiCN can tolerate in steel, iron, titanium, and nickel alloys.

The 6-inch cutting diameter means you're likely hogging out large cavities or facing wide surfaces.
The chipbreaker geometry along all four flutes fractures chips before they can pack the gullets or create heat buildup from chip recutting.
That 0.15" chamfer reinforces the cutting edge against the kind of impact loading that comes with interrupted cuts and aggressive stepdowns.
This isn't a finishing tool.
The surface texture reflects that priority.
You're here to remove material fast while the coating handles the thermal load.
