Temco Hydraulic Knockout Punch Th0004 - Electrical Conduit Hole Cutter Set Ko Tool Kit 5 Year Warranty

This is actually my 3rd tool from TEMCo. I’m consistently impressed how they get this quality at the price point. Works just as well as the Greenlee it’s replacing. It’s smooth, cuts clean, and it’s easy to remove the punched out piece the way it bends it. If you need a punch kit, and this one has the sizes you need, you won’t be disappointed.

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.

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 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.
