TEMCo Hydraulic Knockout Punch TH0004 - Electrical Conduit Hole Cutter Set KO Tool Kit 5 Year Warranty

This is the 3rd kit of knock outs and they work great! The price is much lower than the leading competitors but the quality is comparable to the top brands in the industry

I use this twice a week for work, specifically the 2” knockout. I install solar and batteries. It cuts clean and makes the job go more efficient.

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.

I tried to use this and the cylinder would not budge. I kept pumping the handle but nothing happened. I called their tech support and email them, but it is Saturday, so didn't get a response. I then searched online and found this on Reddit: "Back of off the draw stud until it's almost off the die, hold the cup of the die and give the cranking end of the draw stud a decent smack on a hard surface. " I did that and it worked like a charm. One whack with a hammer and the cylinder broke loose. I have now used it for several holes and it works really well. It would have gotten 5 stars if I didn't have that initial issue. I suggest that the manufacturer include instuctions in the manual under troubleshooting, on how to unstick the cylinder. So far, I like how this works.

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 use to struggle drilling out larger knockouts but this tool is so fast you will think it didn't work. So much cleaner and the cutouts are perfect.. you only need to drill a small hole for the pulled stud.

The media could not be loaded. UPDATE: We still use this for work and are happy every single time. I just wanted to let you know I used it on a 5gal plastic bucket to make a duck feeder. It worked great with that too :)We bought this not really knowing what it was. We just needed a hole bigger than any bit we had. Buying the large bit would cost twice as much. We set it up, read the instructions (kinda) and BOOM!!! We had our hole and were stoked at how easy it was. It is a for sure thing to get if you need holes in metal. It reminded me of my first cuisinart...you spend the large amount of money and end up using it for a few seconds, but oh the time that spent money saves you. If this is anything like my cuisinart it is money well spent as I've had that since my first marriage 30 years ago and its still being used 30 seconds at a time. I wish my video showed the actual hole that was made. it was perfect, but we were just so damned excited about the ease. Get one if you need holes :)

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.
