When to choose it

The RD4125 makes a nominal three-eighths-inch cut and directs chips away from the router. Compare it when the face nearest the router is the visible surface.

It needs a matching three-eighths-inch collet. A different collet or deeper cut requires another model or a documented setup. Test on scrap before cutting a finished face.
