6 Pcs Leather Hole Punch Set — Belt Hole Puncher for Leather Belts, Watch Bands, Soft Plastic, DIY Crafts — Carbon Steel Hollow Punches for Drill 3/16" 1/4" 5/16" 3/8" 7/16" 1/2", Case Not Included

I have never heard of punches that worked with a drill but saw these and thought they might work well on soft materials like rubber and so forth. I used the 1/4" punch on a on seal made of silicone material and it worked perfectly: Just used my 1/4" drill, applied some pressure and it made a perfect hole. All punches in the set I received are sharp.

WOW. The experience was riveting... ;) So, I'm using this(specifically the .5") to punch holes to add extra grommets to a 20mil heavy duty poly-somethingOrOther tarp that I recently purchased. Decided on using some dollar store "roll up" cutting boards (cut to one inch squares) as reinforcement material on either side of the grommet. As a test I cut out a piece of cutting board, put a piece of cardboard box under it and hit the trigger on my cheap little cordless drill. Got some resistance in under a second and thought to myself that maybe this wasn't cutting the plastic as easily as I'd hoped it would. Oh yeah, it cut the plastic alright, and the cardboard. That resistance was the top of my little wooden fold out table that I use as a work bench. Didn't even feel it, and it cut a nice 1/16" deep circle in the wood on the table top. Conclusion, these things are awesome. They're also razor sharp, so keep your fingers out of the way. Would certainly work for leather, denim, or any other thick or tough material up to 1/16", excluding metal.

These are very nice punches. I used them to punch speaker "holes" for a package tray on an old chevy. Worked well and came out nice. Good value.

These make clean holes in thick nitrile rubber and softer foams. Worth noting however, they came rusty (coating, not pitted) which means their oil-coating/storage needs improvement. I did a quick Dremel job on them with a buffing bit and re-oiled and they’re as good as they should have been out of the box. Very easy to sharpen as well.

Worked perfectly to make holes in a backdrop

The 1/4” hole punch bent before making it through the third hole I tried to cut on 5 oz leather using a table top hand press. Design Flaw: A redesign is necessary to ensure more structural support is left on the body when making the side cut/discharge slot. I tried to contact the company but their website is so new it isn’t working yet so my only option is to return the set.

Nice and sharp. Used to put many holes in a felt hat and they cut like butter the whole time. Seem well made and accurate.

I’m working with 1/4” reinforced rubber strap. The product does work with sufficient force applied. The reason for 3 ⭐️ is that it got stuck in my impact driver, we had to put the cutter in a vise and drive the drill off of it. All the cutters are out of tolerance, we tried a different impact driver with the same result. It got stuck in the 1/4” driver chuck. Not just 1 but all sizes were out of tolerance to fit the driver. Use a standard drill and chuck when using this product.

Worked perfectly, very good price. Thankyou.

Great quality, heavy build, super sharp. Worked great on my two recent projects. The price is unbeatable

Easier than hammer tapping

I am not sure of all the possible applications, but they wirk great on cutting foam plugs for fly fishing popper heads

I used these to put holes in a thick piece of canvas like material because I wanted to install toggle bolts to fasten it to the floor. I found the end to be sharp, it did the job without any issues - and now I have a whole set if I ever need to do this king of thing again. They seem well made, are a good weight and look like a quality product.
