The PBM-2500 beveling and facing machine is light weight, just 13 lbs. and is designed to bevel boiler tubes. Our heavy duty tool bits are held in by our wedge lock system.
The torque accepting mandrel with lock in blades (no springs) easily stops any pieces from dropping down into the boiler tube. Our gear drive unit has spiral bevel gears for better torque (more teeth engagement, compared to standard straight gears that other competitors use).
