This needs to be standard in any electrician's van. Unless you like burning up expensive bimetal holesaws and making unclean cuts with tons of collateral scraping. My panel changes now directly bolt up to old service holes because this makes the hole exactly where I need it. It is exact, so there isn't much slack for adjustment. I primarily cut out 2" holes but have also used it for 1.5" holes as well. The design is competent, durable, and well made. The hole cuts clean and releases clean. No struggling to release the cookie. I chucked the garbage standard metal case (with its deceptive latches that don't latch) it comes with as fast and far as I could and store the tool in a tool bag with the bits inside a durable zipper container for optimal organization. Indispensable tool even if it wears out quickly.

Junk, terrible seller. Missing the small rod. Can't use the 1/2" die. Threads are very poor. Need to use hand tools just the thread in the die. Case with Styrofoam. Seller only issued a partial refund to send back their defective item. Seller just denied their is a problem, I'm electrician, I know how to use this, and this product is just not useable, save your money.

Great price, works great, but I did a slight modification.I put a quick disconnect hydraulic coupler for ease of storage.Love it more. Much happier.

The product itself is excellent but the box is not because the hydrolic pump doesn’t fit properly and the no place to organize the parts but for the price I paid and the performance is excellent overall no problem recommend you to buy this product

This item works good! I imagine if I was knocking out holes all the time I might need a more expensive brand but this one works great!

I side the case is just cheap styrofoam, which came broken. So expect the tool to just tool around in the case and get smashed up. Good price tho, so perhaps I'll make a tray for it and live with it.

Haven't put it to the test yet but it should fit the purpose for which I purchased it for

Worked great - once! Not sure what happened. I was punching some VERY thin metal building siding. No issues - clean, easy cut. Went to use it again on a mild steel panel... wouldn't pull the cutter thru. It acts like the hydraulic fluid is leaking by somewhere internally. It just won't develop any pressure any more. As for the punch set, they seem great. Too bad I can't use the hydraulic drive! Bummer!

I'm always skeptical of these cheap Chinese tools, but at less than 10% of the cost of a Greenlee punch set, I thought I'd give it a try. When I pulled out the instruction manual I got a bit nervous. Firstly, it calls the tool a "hydraulic hole digger" and the rest of the "manual" (if you can call a single small sheet of folded paper a manual) is written in horrible, nonsensical "Chinglish" and doesn't actually tell you how to use the tool.However, upon looking at the dies and the tool, they appeared to be of decent quality. The metal case is fairly decent, but the styrofoam insert that holds the parts in place kind of sucks. I just pulled it out and tossed it.My first use of this tool was to make a hole in a 15 gauge stainless steel box. I was enlarging an existing hole, so I didn't need to make a pilot hole. However, if you do, you'll need a 7/16" or 11mm hole for the 1/2" and 3/4" K.O. dies and a 13/16" or 20mm hole for the 1", 1-1/4", 1-1/2", and 2" K.O. dies. I assembled the die set on the tool and a couple pumps of the handle later, the die went right through like it was nothing!I've only used the tool for one hole, so I can't really comment on the longevity of the tool. If something should happen, I'll update my review. It should also be noted that this set includes a set of o-rings to rebuild the hydraulic part.

Excellent value. I would have to spend ten times as much to get a name brand knockout kit. This set has it all. I threw away the Styrofoam inside the case and built wood trays to hold the dies.

A good tool, works as well as a greenlee, but not as expensive!

When I first bought this product I was skeptical. Not anymore. I've been using it for a month now. It is great. Hydraulics are tight and cutting dyes are still sharp and crisp. I have cut about 500 holes on panels and metal building purlins and no problem. For the money, u can't beat this product. Kevin
