Knockout punch for stainless steel
The Greenlee 745H-3-1/2 knockout punch and die kit creates a 4 1/64 inch round hole in materials up to 10 gauge stainless steel. It is intended for electricians and installers who need clean, slug-free openings in junction boxes or enclosures. The four-piece set includes the punch, die and a 3/4 inch draw stud.
Works with hydraulic drivers
The kit is designed for use with battery-hydraulic or manual-hydraulic knockout tools, so a compatible driver is required to operate it. The 5 1/2 inch draw stud fits the tool's ram and pulls the punch through the workpiece. No separate pilot bit or wrench is included in the package.
Capacity limited to 10 gauge steel
The punch handles aluminum, brass, copper, fiberglass, mild steel, plastics and stainless steel at the rated 10 gauge maximum thickness. Thicker stainless or hardened alloys exceed the tool's capacity and will cause premature wear or incomplete cuts. The slug falls free after each punch for rapid repetition.

Questions about this item
How thick a stainless steel sheet can the 745H punch through before the 10 ga limit stops me?
The kit is rated for a maximum of 10 gauge stainless steel, so anything thicker will exceed the punch capacity.
Does the hydraulic ram heat up or get loud during a full day of punching 4 1/64 in holes?
The punch and die set itself has no motor or moving parts, so it produces no heat or noise; only the separate hydraulic tool generates warmth and sound.
Which hydraulic driver do I already need to own to run the 3/4 in draw stud included in this kit?
Any battery-hydraulic or manual-hydraulic knockout tool that accepts a 3/4 in diameter, 5 1/2 in long draw stud will drive this punch and die.
