Hollow End Mills | McMaster-Carr
Mill an angled edge to the entire outside diameter of pipe, tubes, and rods in a single pass with more speed and precision than a handheld scraper. These end mills deburr pipe and tube for butt welds and shape rods for sliding into housings and holes. They attach to screw machines, lathes, and drill presses and can be set up to repeat cuts for multiple pipes.
