I bought this for the metric sized dies and because it was cheap. The metric dies make a smaller hole than the alternative english sized hole saws. for 3/4 fitting you get a 27.5mm hole instead of 28.5 which fits the typical 26 to 27mm 3/4 fitting well. So far I've done a couple of test holes and 3 real 3/4 trade holes in a typical electrical sheet metal box. Works fine.The main issue is that the pilot holes are also metric. 10.5mm (I used 7/16 = 11.1mm) and for the 1" and larger trade sizes the larger pilot measured 19.75mm. Best english fit is 25/32 but good luck finding that size drill bit. 20mm would be fine. 3/4 is TOO SMALL! I have ordered a step bit with a 25/32 diameter. Waiting for that to make bigger holes.Would you believe that a similar Greenlee tool is over $1000? Probably would last longer, but I can buy quite a few of these for that price.I bought direct to save another 20 bucks over inflated prices on amazon and got free shipping too.This is my 2nd Vevor product. So far I'm pleased with quality and price.

I needed a good tool for hole punching in electrical boxes. At work I add components and emergency stops to older units and have seven units up coming for maintenance. I have made some test hole punch on old electrical boxes. Love the hole punch works great need to test on thicker metals.

Great tool case sucks

I've used this to punch holes in a new floor pan for my car. It has been very easy to use and works great.

We manufacture an LED light rail and we are using the punch for electrical knockouts. An exceptional tool. Has paid for itself many times over with labor savings. Would be nice to have more punches available, especially with a square knockout.

Good equipment for the best price

Product arrived quickly and does everything we need it to do. TH

WISH THE INSRUCTION CAME WITH IT. FOR THE PRICE, GREAT DEAL.
