Greenlee 1758AV 2-1/2 Punch

Using the Greenlee 1758AV 2 - 1/2 inch punch is easy. First, make sure it's properly installed in a standard round knockout punch unit. Then, place the mild steel material you want to punch, up to 10 GA (3.500 MM) thick, in the right position. When using, apply steady pressure. For safety, always wear appropriate protective gear like gloves and goggles. As for maintenance, keep it clean after each use. Wipe off any debris or metal shavings. You can also apply a light coat of oil to prevent rusting. Store it in a dry place when not in use.
