Greenlee 744BB Standard Round Knockout Punch 6-3/4 Inch.

The Greenlee 744BB is a great tool for working with mild steel. To use it, first, select the appropriate mild steel material with a thickness between 16 gauge and 10 gauge. Then, set up your hydraulic or manual equipment. Since this punch requires less force than others, you'll find the operation easier. When it comes to disassembly, thanks to its tapered punch design, you can quickly take it apart. As for maintenance, keep it clean after each use. Wipe off any debris or metal shavings. Store it in a dry place to prevent rust, especially since it's made in the USA and you want to keep it in top - notch condition. Always double - check the conduit size, actual hole size, and pilot hole size before starting your project to ensure accurate results.
