100R Series

Tool 100Rm040FA

Roughing heavy sections means dealing with heat, chips, and tool wear all at once. The 100Rm040FA handles 4-inch diameter cuts in steel, iron, titanium, and nickel alloys without backing down from the thermal load these materials generate at size.

The TiAlSiN coating runs cooler than uncoated carbide and extends tool life when you're hogging out material at this scale.
Heat buildup becomes the limiting factor on large diameter roughing operations, and this coating dissipates temperature while maintaining hardness.
The chipbreaker geometry still does the primary work of fragmenting chips before they pack the flutes, but the coating keeps the cutting edges intact longer under sustained load.
The 0.1" chamfer strengthens the corner where impact stress concentrates on interrupted cuts.
Not a finishing tool.
This removes stock so your finisher can do its job.
