Another Top Quality Tool From Greenlee
All the Greenlee tools I've owned have been the best money can buy. This punch set is no exception. I used a 1/2" drive ratchet and 1" socket, and making the punch was effortless.Excellent product Greenlee!

Good price compared to others
Received this to add power strips to a metal cabinet to house ipad mini's. Punched through the cheap steel fairly easily. Had a few holes where the metal was wedged into the cutter instead of cutting clean. Also had to loosen, rotate 90 degrees and re-punch a couple of holes. Bearing on one unit was gritty, others were very smooth. All-in-all a good buy, I always expect little problems with tools like this so really wasn't disappointed.

AMAZING!!!
Not only does it cut a perfect hole it cuts the slug in two pieces so it just falls out, instade of having to fight with it. the cutter housing turns on a bearing while pulling the cutting bit through the metal. We used it on Stainless steel with no problems. Make sure you have a good drill bit for metal, for the pilot hole, then use a step drillbit to get to the proper size for the threads to go through. When cutting bit does not slip and is very smooth.

Green Lee knock out set
Awesome tool. Very compact. Need to purchase the wrench 🔧 separately but very sharp. Also need cutting grease to make last longer. Excellent tool.

I used a set like these 20 years ago and recently biught another set ...
I used a set like these 20 years ago and recently biught another set for a home project. I used a ratchet and socket to tighten the bolt and create the knock out.I saw a quetuon about using an impact to tighten these.It is posible to use one but it will dull the knockout tool faster. I have never used an impact but I have seen the results.This kit is worth the time and effort it saves you.A unu but wiorks to but yuo may exceed the clearance you need if you used a unibit.
