IBOSAD Aluminum Alloy Hydraulic Knockout Hole Punch Driver Kit 1/2 to 2 inch Electrical Conduit Hole Cutter Set KO Tool Kit Metal Sheet Puncher

First off, I know HF has gotten better. I needed a KO set because I’m doing a machine shop and along with 1/2 my tools, my greenley KO set was stolen off my truck. I’ve always wanted a hydronic KO set but the prices are just unreasonable for the ones at the wholesale houses. I’ve been an electrician since 92’ and almost always had the bolt with channel-locks type. I did get to use hydraulics when apprenticing with various larger companies but my own set has been the nut tightening type.Well, on this job, I’ve pulled 30-40 holes, the last one being for a 1-1/2 pipe in a box that was better than 3/16” thick. Had to pump hard but it pulled right through. I was really hesitant about buying a crappy chi-com tool but I needed it right away to keep my guys working amazon could get it to me the next day. It was the kinda deal where if I could just get a few holes pulled before it broke and keep my guys working it would be well worth the < $200 it cost.First job with it, 1/2 way done and I’m very impressed. I don’t know how it’s going to last over the next 10 years or so but my initial impression is that it’s pretty solid. The included replacement seals look to be of top quality. The carry case feels rugged enough to bounce around my truck and has a pivot hinge, not just the bendy plastic hinge. Even the free step bit included is pretty darn sharp and we’ve made a bunch of holes with it. I read complaints of the pull bolt bending or breaking. I have no idea how you could do that. Are they using it as a hammer?

Price is beyond great and item is better than the $2000 GreenLee I have

Only used it one day but it went through a few 2" and 1" holes just fine. Swivel works well. Nice case.Probably best to release the pressure off of it to save it from leaking as others described. No issues so far

Use the product daily, and very impressed with how little effort it takes to make the holes. Mostly using on mild steel and aluminum, but have used on some stainless steel. Cuts like butter so far. Very happy with tool and you can not beat the price! Just wish they made or stocked an accessory kit to go up to 4”

I bought this product 2 years ago, still cutting like butter.Just this jobsitr alone me and my coworkers have used it to knock out holes in 1/8" thick stainless steel panels. Company has the Milwaukee battery powered knockout but this one still cuts faster and without stutters like ol' red.10/10

Out of the box, which was soaked in oil, the hydraulic cylinder was completely cracked open. JUNK...

Bought this knockout about 6 months ago. I really put it to work. Between my helper and myself we would knockout 5-10 holes daily. It punched through everything including heavy duty steel frames. The head ended up cracking up me and i contacted the supplier and within hours of contacting them they sent out a brand new set. Super satisfied with this product seems I’ll be sticking with it

I cannot imagine another hole punch being any better than this one. If they make one just like this It could be good as well, however I just Love this tool.
