SMALL DRILLING AND STOPPING MACHINES 2.1 Shaded area indicates change Rev. 8-17 M ueller Co. manufactures several different small drilling and stopping machines for drilling or cutting holes 1/8" to 3-3/4" in steel or cast iron pipe, and stopping off tees and fittings up to 4". Machines are available in hand or power operated models with a wide selection of drills and shell cutters.

Another important advantage of Mueller ® ma- chines is the similarity in basic design and operating procedures for each. This makes it easier to train personnel in the use of the various drilling machine models. These machines are part of a complete system of NO-BLO ® Equipment, Products and Methods developed by Mueller to perform the variety of operations needed to install, extend and maintain today’s gas systems.
