Genuine Greenlee
I use this with hydraulic pull through head on 0.063 In. Type 304 stainless steel. Cuts better than the old-style punches and far easier to clear slugs.

ordered 1/2 inch, recieved 3/4
never a problem with Greenlee, best knockout, slug buster is by far the best. Just the wrong size, can't fault Greenlee.

great quality, quick shipment
Exactly as described, great quality, quick shipment. Make sure to order the "Knockout Die" if replacing a worn/damaged set; this is only the punch side that has the cutting teeth and is pulled through the material you are punching.

Decent.
You need to buy the 14722P Slug-Buster Knockout Die along with this. Works great when you are absolutely in need a hole.
