Greenlee 36284 PUNCH,RD-1.218 (30.5MM) SB (3/8

Using the Greenlee 36284 punch is quite straightforward. First, make sure you're working with mild steel that's up to 10 gauge. Place the punch on the area you want to punch on the steel. Apply the necessary force to make the punch do its job. When it comes to maintenance, keep the punch clean after each use. You can use a simple cloth to wipe off any debris. Store it in a dry place to prevent rusting. Also, be careful not to use it on materials that are thicker than 10 gauge mild steel, as this can damage the punch and may also pose a safety risk.
