Hougen magnetic drills
Hougen HMD150 magnetic drills fit in places even hand-held electric drills can’t reach, yet drill up to 13/8-inch-diameter holes through 1-inch-thick materials. Sized at 713/16 inches high by 1111/16 inches long and 22.7 pounds, they use Rotabroach 17,000 Series cutters with bayonet-style twist and lock mounting.
