In the late 80s I worked for an electrical contractor doing commercial work there was a journeyman and apprentice both with issues and little commercial experience. The apprentice was using the journeyman's knockout cutters and had the die in backwards. Watching this brought the story back to me, I own the Greenlee slugo buster set and the next one with the ratchet Jarrett has here. I also own a hydraulic set from Princess Auto.
Jeff B. I had an apprentice do the exact same thing. He put the cutter on backwards and pulled it through making a hole. I had to take the cup with backwards cutter in it to a machine shop to get the two pieces separated.
We used an impact driver with a rectangular die which was effective. Also, we were cutting a rectangular hole in a cabinet of thicker graded metal. Please advise.
+Ronald James I have seen the draw studs break when used with an impact driver. The high carbon steal in which the are made of didn’t last with the impact. That being said, I have used an impact driver also.
@@jarrettthejourneyman7196 Thank you. we did have an initial problem with the draw studs. we had to clan and rethread . then we had to use the impact driver because the ratchet would not turn. again thank you for your input.
slv 421 I would check the oil, but if there is no sign of leaking oil I would say seals. I have seen seals blow when you try to cut large holes in stainless steal.
@@jarrettthejourneyman7196 wow, thanks. How thick of steel will it cut, or is it pretty much confined to about the thickness of an electrical box? Would it cut a stainless sink deck?
I didn't know there was a hydraulic hole punch kit. Just thinking about what it must cost makes me cringe. I can't quite understand why hole punch kits are so expensive. It's such a basic tool when you think about it (in theory one could make them in a machinist's shop) so I'm a bit baffled with the cost issue, especially when you think of how handy they'd be for anyone doing a bit of metal work if they were affordable.
@@stopthephilosophicalzombie9017 I wouldn't know. I guess turning the specific hardened steel and then giving it a precise bevel and edge ain't so trivial. Maybe it's worth asking one of the machinists from the many machinists' channels on youtube. Someone is bound to have an idea! Love the moniker btw ; ) lol
@@Stelios.Posantzis Yeah any time you are turning tool steel it gets more expensive. Wear and tear on the lathe, and of course the steel itself is costlier.
+Miguel Apolo I don’t use the hydraulic pump on stainless steal, but the dies work well on it. I have had some pumps blowout the seals when trying to cut stainless steal. Check out my video on the Milwaukee draw set, I have used that one on a lot of stainless steal.

Thank you.. Im a maintenance technician and this my first time knowing this tool.. So informative
+steadfast22 Thank you for watching.
+steadfast22 Thanks for watching.
Thank you saved me from looking like a dumbass not knowing how to use it

Great video ! man, My hydraulic puncher is not working what could it be? oil ? seals ?
slv 421 I would check the oil, but if there is no sign of leaking oil I would say seals. I have seen seals blow when you try to cut large holes in stainless steal.
So is the die actually turning to make the cut, or is it a fully sharp edge that gets pulled and literally punces it out like a paper hole puncher?
The dies remain still and the sharp edges cut through the metal. Thanks for watching!

@@Orrphan I have cut a lot of stainless steel with the knockouts, they should have no problem cutting a hole in a sink.
@@jarrettthejourneyman7196 awesome. Thanks
08:53 : a Mickey Mouse hole! ; )
That's EXACTLY what I thought when he pulled the punch out!

They probably aren't trivial to make though. Require skilled machinist to make. I saw one for $125 recently. That's not unusual for a quality tool.

how much
Can I use on St steel???
