Greenlee 730-5/8 Standard Round Knockout Punch Unit, 5/8-Inch
Greenlee round standard metal punch units are complete units consisting of punch, die and draw stud. They can punch quick clean holes through metal up to 10 gauge (check specs for specific punches). They can be used with battery-powered, hydraulic, ratchet or manual drivers. Properly assembled through pilot holes, they will make clean, fast and accurate holes. After cutting the slug falls free in the die, and a quick tip drops it out.
