square disc cutter comes with 7 hardened steel punches ranging from 4-16mm in
width and a square steel disc cutting block. The punches are machined flat and

beveled at the other end for use with a heavy mallet or hammer. This disc cutter will cut up to 18 gauge metal, and can be used
on a rubber mat or block to ease the cutting process.
use it, remove all punches from the block, and select the size punch you would
like. Align your sheet metal in the slot, and
place your punch, sharp side against the metal, in the correct slot. Strike the
beveled side of the punch with a heavy mallet until it pierces through the
sheet metal. Be careful of your fingers and other items on your work surface.
