Why Reed

A great deal on a versatile tapping machine that is priced well for the market.

The Mechanical Hot Tapping Machine allows drilling through the pipe wall via fittings inserted into the service saddle or thread-o-let. With the right hole saw, hot tap into steel, galvanized, copper/brass or PVC pipe for up to 4” valves. The main body assembly and shafts provide a watertight seal to allow drilling under pressure (hot tapping). DM3MECH consists of the main body assembly that fits into a 1 ¼” NPT fitting (not provided), along with ½” diameter shafts, hole saws, arbor, coupon retaining drill bit and more. DM3MECHB excludes the holes saws and hole saw arbor. Hole saws are to be used per hole saw manufacturer's recommended RPM with a 3/8" or 1/2” drill motor. Reed's Mechanical Hot Tapping Machine is the tapping machine only with valves, saddles, fittings and piping supplied by the operator.

NOTE:  Not recommended for ammonia, gas or other caustic systems.
