Yescom 15 Ton Hydraulic Punch Driver Kit Conduit Hole Cutter Set Manual Hole Knockout Puncher Tool w/ 10 Dies for Aluminum Brass Stainless Steel

Package arrived in 2 days and is very heavy at 47lbs. No instructions except for the warnings of use. YouTube provides an excellent source of information so it was fairly easy to figure out. Practiced on some scrap metal at first and it does cut like butter. Comes with additional gaskets for hydraulic pump. All dies are oiled and wrapped separately. Dies are very sharp. Case latches are somewhat loose and could be of better design. You do not want this thing popping open while carrying it about.

Am a electrical contractor , I got this last week so only have punched a few holes so far, but have to say works great. and didn't have to pay thousands of dollars , Made in china, but for the price can't beat it. It is a little heavy, Case is okay , but will change it to a better one, for the money I saved I can get a really good one, lol.

Used it one time on a PRL2A panel. Blew the hydraulic line. the dies are soft. pretty much can tell the threads will also strip. doesn't matter though, will need to modify it for a line capable of taking the pressure.

Works great , buy a large step drill so you can drill center hole for the die arbor to fit through your centering hole and your set!

Well i was skeptical about ordering this set since i am partial to Greenlee cutters. So far, so good, and they cut well. It takes a few to figure out how to set up with the different threaded rods. Seems their is some leaking of fluid but not a deal breaker. If you are a heavy user invest in Greenlee, but if you use occasional they work perfect. Only complaint is the threads will strip very easy.....

This is a great deal for the price, it comes with all of the trade sizes from 1/2” to 4”, it has performed great; and the whole kit is less than the price of one of the Greenlee dies.

Seems like the tool is decent quality. However, if you need to put the hole centered on a specific point you typically draw crosshairs and most KO sets have hash marks at on each side of the punch to line it up perfectly and get the hole exactly where you want it. These KO's do not have marks to do this. Kind of a big deal if you're looking for accuracy. We had to engrave, mark the 4 marks on each head to ensure accuracy. Product would be much better if it had the hash marks.

Great knock out set - worth every penny. (The carry case could use some updating - they use cardboard to hold everything stable - NOT).

Great product

Opened up the box and it was filled with oil so I decided to try it to see if it’d work and it leaked out all the oil and it does not work!
