TAPMATE
™
XL-424 Operating Manual
MACHINE OVERVIEW
While you may be familiar with the Tapmate drilling machine, this machine is larger and has different
operating requirements. These include:
• The TapMate XL-424 has no sliding tubes or brakes.
• Fewer turns are required to complete the tap (in most cases).
• Two jam nuts instead of one have been used to lock the cutter in place on the TapMate XL-424 (14"-24").
• TapMate XL-424 feed rates are slower because of the new threads.
The TapMate XL 424 drilling machine consists of four distinct sections. These sections are the Shaft, Lead
Tube, Thrust Tube and the Brake Tube.
The threaded Thrust Tube is located in the center of the machine and the Brake Tube is positioned toward
the back of the machine. Together, they control travel of the Holesaw and pilot drill. Prior to the cut, the
Holesaw and Pilot Drill are extended through the valve and tapping sleeve neck to the pipe wall using the
Brake Tube Handles. After the cut is complete, the Holesaw and Pilot Drill retract back out of the way to allow
the valve to be operated.
After the tap is completed and you are drawing the Cutter away from the pipe, the thread pitch prevents
water pressure from turning the brake tube.
The Lead Tube and Lead Nut, are located inside the front end of the Thrust Tube. Together, they provide
the forward pressure necessary for the Pilot Drill and Shell Cutter during the cutting
operation.
The Shaft is a single piece running through the center of the machine. It is threaded on the front end to
accept the Pilot Drill and Shell Cutter. The other end of the Shaft mates with the hydraulic drive unit.
