Greenlee 12307 PUNCH UNT-3/4 (POP)

Using the Greenlee 12307 is straightforward. First, select the appropriate driver - you can use a battery - powered, hydraulic, ratchet, or manual one. Then, attach the standard Greenlee dies and draw studs to the unit. Place the material (like mild steel, aluminum, fiberglass, or plastic) where you want to punch a 3/4 - inch (19.1 mm) hole. The unique punch profile will split the slugs, making it easy to remove them after punching. When it comes to maintenance, keep the unit clean and lubricated regularly. Check the dies and draw studs for wear and tear and replace them if necessary. Always follow the safety guidelines of the driver you're using. Also, ensure that the material thickness doesn't exceed 10 ga. mild steel to avoid damaging the unit.
