Simple, Accurate, and Fast Hole Enlarging

New magnetic drill pilots simplify process for portable magnetic drills

Hougen takes the difficulty out of enlarging existing holes using its new hole-enlarging pilots and Rotabroach® cutters in portable magnetic drills.

Enlarging an existing hole can be a time consuming challenge using conventional holemaking tools. To simplify the task, Hougen Manufacturing Inc. has introduced a new Hole Enlarging Pilot System that uses its 2-in. D.O.C. Rotabroach® cutters and portable magnetic drills.

The pilot is a two-piece assembly consisting of a threaded pilot and three different sized screw-on nosepieces, each having flats on opposite sides for easy tightening and removal with a wrench or pliers. Using a portable magnetic drill, the cutter and pilot is inserted into an existing hole, then by re-drilling the hole its diameter is increased by 1/8 in. For example, an 11/16-in. hole can be quickly and accurately enlarged to 13/16 in.

The replacement nosepieces have a tapered edge for easy insertion into existing holes and are currently available in three sizes, 11/16 in., 13/16 in., or 15/16 in. One pilot works each of the three different-sized noses and with Hougen’s magnetic drills.

Hougen holemaking technologies also include 26 models of portable magnetic drills, plus a wide range of annular cutters for various applications, and Punch-Pro Portable Electro-hydraulic Hole Punchers.
