Abstract
A tool for rounding the end of a tube has an anvil with a cylindrical midsection and a tapered forward end. Extending rearwardly from the rear end of the anvil is an elongate shaft, and around the elongate shaft is a cylindrical hammer which slides axially along the shaft to strike the rear surface of the anvil. The hammer is retained in the shaft by any appropriate means such as a threaded nut or external flange at the distal end thereof.
