An ID clamping boiler maintenance tool that can bevel and remove membrane simultaneously without cutting oils and no heat affect zone (HAZ) to produce superior welds is available from Esco Tool.

The Esco Wart MILLHOG Beveler mounts rigidly to the tube ID, is self-centering, and provides torque-free operation for clean metal removal without cutting oils and no HAZ. Featuring a robust gear drive with dual tapered roller bearings, this beveling tool has a sealed mandrel to keep debris out and can bevel, face, and remove membrane simultaneously.

Designed for tube and pipe from 0.75" to 4.5" OD, the Esco Wart MILLHOG Beveler is only 2.625" W to fit between tubes for single tube maintenance in a boiler tube waterwall. Equipped with attached clamping and ratchet feed tools, it is available with pneumatic and electric motors and the EscoLock blade locking design directs heat away from the tube surface.
