Prepmaster


The High-Performance Light-Weight Pipe Beveling Machine
12.7 mm I.D. to 57.15 mm O.D. (0.5" I.D. to 2.25" O.D.)



The PREPMASTER is a right angle, I.D.Clamping Pipe end prep tool for small diameter boiler tubes and pipes. Featuring a push-pull clamp and release mechanism with permanently attached clamps and wrenches, this self-Patented clamping system permits the clamps to release as easily as they tighten, no hammer needed!centering tool performs any angle of bevel and produces a smooth continuous chip.

Eliminating the possibility of loose parts falling down the tubes, this high performance tool utilizes the FABMAX wedge-style blade lock system and TiN coated blades for chatter-free beveling.



  1. Narrow body 38.1mm (1.5") wide for beveling a single tube in a waterwall
  2. Three inter changeable motor choices, Pneumatic, electric and battery
  3. Patented clamping system permits the clamps to release as easily as they tighten, no hammer needed!
  4. Permanently attached wrenches keep the operating essentials easily at the operator’s finger tips.
  5. Dual opposed ball bearing supported gear drive design
  6. Fabmax lock blade lock holding system minimizes vibration and maximizes tube and pipe bevels per blade.

Designed for limited access boiler tube beveling.


The Prepmaster is a right angle I.D. clamping tube beveling tool that is only 38.1mm wide and fits between boiler wall tubes for beveling single tube and other boiler tube applications with restricted access. The tool is made of heat treated steel for durability and proprietary bearings support heavy duty gears for smooth operation and long durability on the toughest boiler applications.


The pull-push clamp and release system with permanently attached wrenches and clamps eliminate the possibility of loose parts falling down the tubes. This high performance tool utilizes the lock wedge style blade locks system and TIN coated blades for chatter-free beveling.


Power choices include pneumatic, electric and battery. All motors are easy to switch and deliver optimum torque and speed that reduces bevel time by pulling a thick chip on the toughest boiler tube alloys, without cutting fluids.
