Happybuy Hydraulic Hole Punching Tool Hole Punch Machine CH-60 for Copper Aluminum Iron Stainless Steel Plate with 31T Copper Bar

Great press works as if should have used it to punch holes in 1/4 inch plates and I have done just about 400 holes so far. Works very well. One thing that I find an issue is the die unscrews itself after about 10 punches so keep an eye on the die to tighten it every so often. If I was only just using one die then I would just apply some loctite on it. But I’m changing dies for various projects.

Bought this for a signing project I had going on at work. Easily saved us from having to buy probably $2k worth of drill bits, not to mention the time savings. We used this on 3/8" steel I-beams with a handheld hydraulic pump(not what it was listed as to be used for). But it worked, and even managed to punch through a 3/16" sheet of 304 stainless(shattered the die, but made the hole!). I've bought 3 of these so far. The first one completed approximately 600-700 holes before the frame began to deform. (Not upset, as the tool paid for itself in time/payroll savings alone). The onky thing to note is that when you try to adapt fittings to work with this, you need to be aware that the thread coming out of the unit is British thread, not SAE/Metric, or even NPT. Most hydraulic supply stores can assist you in getting set up properly. Only real problem is finding the dies for this. If the manufacturer would set different die sets separately, that would be great. The ones that came with it however, do work and are quite durable.

This tool is awesome. There are many dies available to suit your requirements.

My bueno me gusto mucho

This unit is impressive, but I didn't receive the 1/2" dies, and am having a hard time getting it sorted. My only option is to return or exchange. Other than that, it seems like a great addition to the shop.
