100R Series

Tool 100Ri156LA

Small diameter roughing presents a challenge. You need material removal rates but the tool has to survive the cut without snapping under aggressive loads. The 100Ri156LA runs a 0.1563" cutting diameter with TiAlSiN coating. That coating adds lubricity and heat resistance when you're pushing feed rates in tighter spaces where chip evacuation gets more critical.

Four flutes with chipbreaker geometry fracture chips before they pack the smaller flute gullets.
The 0.004" chamfer strengthens the cutting edge against chipping when you're taking heavier cuts than the diameter would normally suggest.
Steel, iron, titanium, and nickel alloys respond well to this approach when you need stock removal in confined areas or detailed roughing passes.
The surface won't be finished.
That's what the finisher is for.
