100R Series

Tool 100Ri375A

Small diameter roughers take a beating. Heat builds fast in tight quarters, and chip evacuation gets messy when you're pulling heavy cuts with limited flute space. The 100Ri375A handles this with chipbreaker geometry that fragments material before it can pack or weld to the cutting edge.

The TiAlSiN coating adds thermal barrier protection where it matters most.
This coating runs cooler than standard TiAlN and holds up better against the adhesive wear you get with sticky materials like titanium and nickel alloys.
The 0.006" chamfer strengthens the cutting edge without sacrificing the aggressive bite you need for roughing operations.
Four flutes balance removal rate with chip clearance on steel, iron, titanium, and nickel alloys.
The surface won't be finished when you're done.
That's what finishers are for.
