100R Series

Tool 100Ri125LA

Small diameter roughing means more spindle speed and more heat buildup per unit of cutting edge. The 100Ri125LA handles this with TiAlSiN coating over 4-flute geometry designed to fragment chips before they can pack or pull heat into the cut.

That 0.125" cutting diameter wants to run fast in steel, iron, titanium, and nickel alloys, but standard end mills load up or wear out quickly at those parameters.
The chipbreaker geometry along each cutting edge breaks material into manageable pieces that clear the cut instead of welding to the tool.
TiAlSiN coating adds thermal barrier protection where small tools need it most.
The 0.004" chamfer strengthens the cutting edge against microfractures that kill small diameter tools.
This isn't a finishing operation.
Remove material, clear chips, move to the next pass.
