Abstract
A metallic pipe-cutting apparatus is constructed to cut elongate metallic pipes such as aluminum pipes into shorter pipes of a predetermined length, and comprises a main body, a chuck disposed rearwardly of the main body so as to hold trailing ends of the elongate metallic pipes, and a supporter disposed forwardly of the main body, with the main body interposed between the chuck and the supporter. The supporter comprises supporting pins which are to be inserted in leading ends of the pipes whose trailing ends are clamped by the chuck, so that the pipes clamped at their both ends are moved intermittently a predetermined distance so as to be successively cut into the predetermined length, with their outer peripheral surfaces not being scratched or flawed due to sliding contact with clampers or other members.
