The No. 20 tool offers 20 tons of punching power to meet heavier job requirements, and greater versatility in punching flat sheets and angles. Includes one 1/2″ round punch and die set. The No. 20 and No. 20 CTL are similar, except that the frame around the die pocket of the CTL20 is machined to allow punching close to the web of angle iron (9/16″ from web to center of hole) Options for these tools include a ratchet attachment (for No. 20 and No. CTL20) to permit operation in close quarters and a pipe handle to provide adequate leverage with minimal effort.
