Hougen 10533 Pilot for older 1/2" - 11/16" & 13mm - 18mm Rotabroach Cutters 1" D.O.C.

The pilot serves three functions when used with "12,000-Series" cutters in a portable magnetic drill; 1) Locate the holes center point, 2) Initiate coolant flow to the center of the tool, 3) Eject the slug at the end of the cut. Always use a sharp pilot for best results.
