TH0390 – Manual Knockout Punch Driver Kit (Set) for ½ inch to 2 inch Electrical Conduit Hole Sizes (1/2"-2" Conduit Size)

I used this to make a bunch of 3/4" and 2" holes in wire tray for a solar installation. It went pretty well but I wished that I had either a stubby electric impact wrench or the hydraulic version. If I were a professional I'd buy the hydraulic. The time and effort it takes to turn a wrench on this tool is significant. It works well and if you have time to spare you'll save a ton of money over hydraulic. I put a conduit bender on the end of my ratchet about half way through as a cheater bar. You need quite a bit of force to finish it off. I used it for about 12 2" holes 2 1.5" holes, and 2 3/4" holes. The 3/4" were really easy, the 1.5 I did with a ratchet alone, but 2" is right at the limit of what you can realistically do by hand I think. And that's only if you have room for a cheater bar. For infrequent use, this is the tool to get, especially if you can use an impact wrench. For regular use though, step up to hydraulic.

Fonctionne très bien!Mon seul regret est de ne pas avoir acheté ça beaucoup plus tôt car ça travaille extrêmement bien. Me semble de très grande qualité

trabajo el hace te pero klein un como funciona no producto buen un es precio el Por

I needed one of these for work but I didn't want to spend a lot if I didn't have to. I don't use it every day so I don't need top of the line. This works fantastic and is totally worth the money especially considering it comes with a storage case. Just make sure to use it with a ratchet and socket. You can use it with an adjustable wrench but I wouldn't recommend it if you have to make more than a couple of holes.

I'll provide updated review later. This a gift for uncle. once received he will provide his view and ill relay them here.cheers
