Tear Drop Shaped Disc Cutter 4 Sizes with Handle Sizes 11X17 to 20X30mm

Cut perfect tear drop shaped discs every time! This disc cutter features 4 punches , in sizes approximately 11mm x 17mm up to 20mm x 30mm in size. The holes have been machined and honed to make fine, clean cuts. The punches are oil-quenched tool steel that have been drawn for hardness and durability. The base is case-hardened and ground. You can cut soft sheet up to 20ga. The tool measures about 3"x3". The black handle rotates to open and close the gap that your sheet metal slides into for a secure grip. To use it, remove all punches from the block, and select the size punch you would like. Place your sheet metal in the slot, adjust the lever to fit your metal, 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.4 Sizes Sizes 11X17 to 20X30mmPunches have a sharp cutting end and a beveled end for strikingBest for use with a maximum of 20 gauge soft metal
