100R Series

Tool 100Rm080

Large roughers carry more load than smaller tools, but they also generate more heat per revolution. The 100Rm080 pushes an 8-inch cutting diameter through steel, iron, titanium, and nickel alloys without coating because the uncoated carbide substrate runs cooler in interrupted cuts where coating can chip at entry and exit points.

Four flutes balance metal removal rate with chip evacuation at this diameter.
The chipbreaker geometry fractures chips before they can wrap around the tool or pack in the flutes - critical when you're moving serious cubic inches per minute.
The 0.15-inch chamfer reinforces the cutting edge against the shock loads that come with heavy roughing passes.
This isn't precision work.
It's about clearing material efficiently so your finisher has less work to do.
The surface finish reflects that priority.
