100R Series

Tool 100Rm160L

Large diameter roughing means serious material removal and serious heat generation. The 100Rm160L handles both with 4-flute geometry designed to clear chips before they become problems. That 16" cutting diameter gives you substantial engagement, but the chipbreaker geometry along each cutting edge fragments material into manageable pieces that won't pack your flutes or drag heat back into the workpiece.

This particular SKU runs uncoated.
Sometimes coating adds complexity where substrate performance is what you need.
The 0.2" chamfer strengthens each cutting edge against the kind of interrupted cuts and heavy feeds that large diameter roughing demands.
Steel, iron, titanium, and nickel alloys respond well to this approach.
You're not chasing surface finish here.
You're removing material efficiently so your finisher can do its job without working overtime.
