i bought one for myself as electrician, after couple months i got another one for my brother. because of good customer service and fast reply to my request.the kit is easy to work with. so far so good.

This product is great and compared to other manufacturers you cant beat the price. This is an electrician tool so the sizes are for conduit so they aren't true measurements. So the 1/2 inch knock out is 7/8 if you want to know the rest look them up its a standard. If you don't understand this, this isn't the product for you. Stop complaining the sizes are wrong they aren't you just don't understand the product. The bit does pull much faster then others I've used so I do expect it to fail eventually but who knows.

This punch does exactly what I want it to do. Two complaints though…1) I did not receive the unibit that the picture shows is included with the kit and 2) I would like this punch even better if it had a swivel fitting on the pump end like it does the press end. Overall, this is a huge timesaver and cuts out very nice holes!

I purchased this product 7+ years ago. Being an electrician I have punched countless hole into panels and boxed including stainless steel. I am surprised how well it has held up. I have no leakage and have only had to replace on die (3/4) because it was getting dull. For the price at the time. I consider it a great purchased and have gotten my money's worth and then some.

Fonctionne très bien, bonne qualité et très satisfait pour le prix payé !

For an economical set up as this, being an experienced electrician for nearly three decades, this is a good product. I was surprised that it came with a step-drill bit (unibit as we call it in the field). It has the cutters that shear the knockout, like the more expensive "GREEN" product, not to knock any name as that is a really good set (experienced electricians will know what I mean there. At any rate, if you are looking for a good product, this is a good one. Comes with more than one size spacer, which I really like about it as well.

I actually bought this to use with the Lisle 17350 exhaust pipe expander kit. The stud in this kit fits both sets (Temco and Lisle) perfectly so no compatibility issues there. If you are working with thicker exhaust pipe or especially stainless it can be very hard to expand it manually and this setup works amazingly well. The 9 ton hydraulic capability not only gives you the power you need but it's also alot easier to control how much you're stretching the pipe so you can really get a perfect fit prior to welding anything. I know overall it's not cheap setup at all but it will save you a ton of time and money if you're working with stainless exhaust (which is not cheap either) so I highly recommend it.

Today I use 3/4 inch it was so smooth clean cut I hope that will still like this I like it so much I m proud about this tool

I reviewed just after purchase (at the end) but thought i should update after 18 months: The dies are holding up well for what this set cost I did not expect it to last but it has. I have used it quite a bit and did tune up the 1" and 1.5" punches, As I mentioned I use it with my green dies for the larger sizes i have and the ram will do 3" holes well. I dont to much larger than 3". If only 1 small 1/2 or 3/4" i use a carbide hole saw since i have to drill the pilot anyway but if doing larger and or more holes this baby is really easy to use and quick, I oil the punch with every use and it only takes a few pumps and the hole is done, if i were to purchase again i would get the larger set up to 4" but when I purchased this I was gambling because it was 1/8 the cost of the green one. I have had no problems with the ram or draw bar and i mentioned i did use a dremel to tune up the cutting edge on the 1" & 1.5" but have done the same on my green set when dull (they may have punched more holes but at 1/8 the cost a little tune up is the same as i do with the green ones) the case has held up well. my apprentice bought the same kit and some of the guys in his class gave him a hard time until they heard that my set has lasted, the only thing that could make this set any better for an electrician is a 1-7/32 punch for industrial control panel switches where I may put 30+ holes in 1 panel (that 1 punch cost almost 40$) I five give the set 5 stars for the cost it should get more but thats all they allow, and I did not request a free gift for my review so you know it is honest.original review:for the price this is an awesome knockout set. I have punched a few holes and it worked as well as my green one. the dies from my green one also fit the draw bar at 1/8 the price hope it holds up but for the price I could buy quite a few new sets compared to the green one.

The media could not be loaded.

I actually would give this unit 4.75 stars, but I didn't want Amazon to show 5 stars, because it's not quite perfect. But with just a little bit more effort by TEMCo, it could be truly excellent. I bought this unit to punch various holes in project boxes for my electronics projects. The boxes are made of about 1mm thick (20 gauge) aluminum. I have not previously used a hydraulic punch, just manual ones, so this review is written from the perspective of somewhat of a beginner.On the positive side, the various pieces are well packaged and seem very sturdy. As others have remarked, this unit is a great bargain for the price. TEMCo has obviously put some care into the presentation. And I like the warranty. I tried out all of the punches and they work beautifully. The four largest punchout die (1" -> 2") thread on to a main stud, which in turn threads into the hydraulic ram. The other two (1/2" and 3/4") punchout die thread on to a smaller adapter stud, which in turn threads into the main stud.Two thick spacers (provided) fit over the main stud and are used to accommodate the thicknesses of the various punchout die. You will need to play with the spacers a bit to maximize the throw of the hydraulic ram to get the best punch, depending on which punch die you use.Here's where a problem appeared. I could ... not... get (frustration!) the right spacer combination for any of the four largest die. The two spacers provided were too thick. I needed something smaller. I suppose that I could have adjusted how deep the main stud threaded into the hydraulic ram to change the throw distance of the punch. But that seems risky since a lot of force is applied to the main stud and I wanted it fully threaded into the ram. So I went to my local hardware store and purchased some hardened washers that were large enough to fit over the main stud. Each washer was about 9/64" thick. I found that three of these washers worked perfectly to give optimum throw for the 1-1/4", 1-1/2" and 2" die. And I added a fourth washer to optimize the throw for the 1" punch out die. For the small 1/2" and 3/4" die, two of these washers in addition to the thick spacers provided in the kit gave the best throw. I think these should have been provided in the kit, or if they really aren't needed, then a better description of how to use the spacers provided would have been nice.A couple of other useful tips. Put a little oil on the threads of the studs and the punchout die. It makes it easier to assemble and disassemble the die, especially as they tend to jam if the cut is not complete. Also, the pilot hole that you must drill in the panel is very large if you are using any of the larger (1", 1-1/4", 1-1/2", 2") punchout die. I found that the 1/2" punchout die gives a hole exactly the right size for the pilot hole of the larger punchout die. This saves having to muck around with a very large drill bit.So, all in all, a beautiful unit. Just needs a few smaller spacer/washers and a bit better written description to be perfect.
