Metal Pipe and Tube Bevelers

Beveler Shown with Air Clamp (Sold Separately)

Prepare metal pipe and tubing for welding by giving them smooth, beveled edges with these air-powered bevelers. They have a cutter head that accepts blades (sold separately) with different bevel angles and cutting patterns, and holds them rigidly to reduce vibration and heat, extending the life of the blades. To minimize fatigue and prevent loose parts from falling down the pipe as you bevel, they come with two attached wrenches. Their feed wrench helps you move the tool into the pipe as it bevels by tightening and ratcheting the wrench back-and-forth. Use the clamping wrench to secure your beveler within the ID of the pipe.

Swap out blades to get different bevel angles and replace worn blades. They have a TiN coating that makes them last longer. Use J-bevel blades to prepare the ends of pipe and tube for welding with an orbital welding machine.

Replace the clamping wrench with an air clamp in order to clamp and release your beveler from pipe with the flip of a switch, shortening the time between bevels.
