AMZCNC 1/2" Conduit Hole Size Knockout Punch Unit with Manual Draw Stud – (0.86" – Actual Hole Size)

Works like the name brand product at a much better price. The included wrench is ratcheting which makes it much quicker and easier to complete the punch. I used it to punch holes for 2" conduit, it's largest size, through a steel panel and it worked well.

Worked will for my use.I liked how the punch cut in 1/2 the slugs.The included wrench is 19 mm but I used a SAE 3/4" socket with my impact wrench.Now if they offered this punch set with their hydraulic ones that would be great.https://www.amazon.com/dp/B096TFHN4Q

Quality was top notch. Shipping as promised. Cuts a 1” hole.

Really nice hole punches....but, they are all mislabeled. 2" is actually 2.45" etc.

I used the 2.5", 1.5", and 1" sizes. All of them worked well for punching holes in a large metal pull box as well as to enlarge the smaller knockouts in a Leviton structured media panel metal box.

I used a step drill to create a hole for the press screw, and used this to make four holes in electrical panels. The holes were clean and smooth while the cuttings were easy to remove. There is no wear on the tool.

Price was decent compared to other brands , and it worked well.

This is fine if you have a few holes to do but it does not hold up overtime. I have a fairly large solar project. I am working on. I had about 24 different sized hole knockouts I needed to do, primarily in metal wire ways. The threads of the large bolt do not hold up overtime, even though they were greased for each hole that I knocked out.Wish I had just spent extra money and bought the hydraulic punch out kit. Now I’m in the middle of this job that I cannot have downtime on and I have to figure out what to do.

I use this for making holes in circuit breaker panels, and so far I haven't had any problems doing so.Well made cutters.
