Works great. Very clean holes, perfectly sized. Quality tool.

ATS INT HOLE PUNCH 2-1/4&3-1/8

Works well. What seems to work best is continue to tighten the nut until you hear two. I use it in combination with a hole jig.

ATS INT HOLE PUNCH 2-1/4&3-1/8

Worked very well. Made short work of cutting instrument holes after lubing the threads. Just wait for the second click.

Life saver! Well more like time saver! Wow how quickly it was able to cut through .085 T3 aluminum, took some effort at the end with sheetmetal this thick, but it did it and it did not warp or bend as anticipated. Its worth the money....as I always say...time is money and what is your time worth?? Highly recommend! Great tool, high quality.

Great tool.. I was reluctant to purchase this tool based on the reviews. I went ahead and ordered it and it works great. Punched 8 holes in a 6061 T6 .90 dash panel the first day I had it and it was simple.

i am amazed how quickly it arrived. great tool used it to punch over 21 holes already works great a quality tool well made highly recommend both tool and your company. if i could give more stars i would this coming from a military aircraft structural mechanic first class ray reininger

Works great!

Good for popping quick holes. Will warp the metal depending on thickness. I bought this to make a panel overlay with some .032 aluminum and was left with some warping outside of the instrument hole. Cut a new hole for a G5 in my thinner primary panel and this was perfect for that job.

Nice product for making very clean instrument holes. Only made a few so far so I cant tell you if blades dull quickly after use or not. Only down side was no instructions for use, however you can play with it and figure it out quick enough. Basically sandwich the sheet metal between the cutting piece and hole and turn the nuts until it punches through.

I punched two 2 1/4 holes and two 3 1/8 holes in a 16 ga. (0.062) aluminum 6061 Instrument panel. The threads on the 5/8 thru shaft that is used to line up the punch and apply the necessary torque was not hardened and the threads stripped making the punch useless! I need a replacement 5/8 shaft to do use this punch again.

The claim that this tool is suitable for up to 0.125” aluminum is not correct. We u it on 0.086” aluminum and didn’t even get one hole made before the thread of the center bolt stripped. It required so much torque that it warped the material and there’s absolutely no way it would work with other instruments installed like suggested in the description as it requires a long handled socket on each side and a lot of muscle. Very disappointed and will be attempting to return.
