How the Corner Radius Enhances Your Finish

The corner radius of an insert might sound technical, but think of it as the curve on the edge of a knife blade. A 0.359-inch radius means this insert gently rounds the edge of your cut instead of making a sharp angle. This helps in producing smoother finishes on your metal parts and reduces stress on the tool edge—much like how a slightly rounded shoe sole offers better comfort versus a perfectly flat sole. In practice, that means fewer rough spots and longer tool life.

Installation and Maintenance Guide

Setting It Up
