1/2" conduit We use these in electrical for conduit holes

Thank you Mike, and they are designed to cut an oversized hole? Is that correct?

[@mikebennett6373]

@@J_R_Shop right. 1/2” conduit would require a 7/8” hole for the fitting

[@J_R_Shop]

@@mikebennett6373 it took me a few minutes to figure that out, it makes sense that the hole needs to be larger than the actual conduit. Thank you for that information Mike!

@@J_R_Shop 1/2" thin wall conduit has an OD of 0.706", 1/2" pipe is nominal 0.840" OD, 1/2" copper pipe is 0.625" OD. There's tables for all these, it will drive you nuts.

This is primarily an electrician's tool, therefore the die is marked based on the PVC conduit size being used. A 1/2" die would cut a hole the correct size to accept a 1/2" TA (terminal adapter) , which then accepts a 1/2" conduit. Thanks for the review and hopefully this explanation helps!

Hello Alvin. That's a nice tool. I purchased the Qmax brand steel punches years ago, and they really come in handy. I bought the 1/2, 5/8, 3/4, and 1" punches. I see that you can get a set from Harbor Freight 1/2, 3/4, 1, and 1-1/4". But the description does say "pipe and conduit" so they may be like yours. One thing for sure is to lubricate them. They will cut easier and last longer. Nice birthday gift. George B

Hi George, I don't think the ones I have would take daily use very well, but for the occasional user, they will be fine...and I agree with you on lubing them each time, most definitely will help to cut and save the tool from wear. 😊

7/8” hole is for Electrical trade size 1/2” conduit

[@J_R_Shop]

Hey thanks.

[@sizzle073]

Well I’ll be dipped! That’s a great excuse! My wife always says I purposely break stuff on her car so I can get a “new tool”. Now I’ve got another in my pocket to throw her way when I want, er I mean need a new tool! Thanks Alvin! 😂

[@J_R_Shop]

Lol Troy, Christmas gifts in October are another good one that seems to work! I'll have to try your method also, the money flows much better when the wife's car is broken down. 😎

[@christopherhenry3472]

Always love your videos. Just tearing down my 65 convertible too so Im excited for every video you put put. Make the mistakes first so I don't have too lol

[@J_R_Shop]

Thank you Christopher, remember to bag n tag all of the parts! 😋

[@michaelwalters266]

As Mike said those sizes are for conduit sizes, as a retired Ford electrician we used those all of the time. The punches we used were made by Greenlee, it's possible that they also make specific sizes, you could check their website. I've never seen them but you would think someone would make them.

[@J_R_Shop]

Thank you Michael, for all the holes I'll be making, I feel these will do just fine...I'll use the die that makes the hole I need at the time. 😎

[@michaelwalters266]

Also would like to add that if you try that on 1/8 steel you might end up needing that repair kit. LOL

[@J_R_Shop]

Lol...you are right Michael, the 1/8 steel will most likely be a stretch for this set up!

ECTG1 (eric the car guy) - he says "hey, if it's your birthday, please enjoy this electronic confection I found online", then inserts a pic of a piece of cake...(something a bit different every time, but always looks like a birthday cake type item)

[@J_R_Shop]

Hey Sue, that's a fun thing to do for the viewers. Thanks for the tip! 😊

[@442olds7]

Those over seas tools are cheap for many reasons, one is that they let the consumers do the quality control, which is nice of them I guess 🤔. Good hole maker, easy and makes a nice clean hole.

[@J_R_Shop]

I definitely wouldn't suggest that this is of a quality that could be used professionally. For me however, I'm pretty sure I will not wear it out anytime soon, and I can see using it for other sheet metal forming projects, as long as the pump holds up.

[@joernone]

Alvin, C'mon...7/8" being 1/2". What's the dif? Picky-picky. 🤪 Regards, John

[@J_R_Shop]

I know John...just too fussy! It all makes sense in the world of conduit installation...it's the conduit size , and the hole required for installation with adapters. I like it when I learn something new. 😁
