Leather Hole Punch Set - 6 Pcs Drill Bits Set 3/16" 1/4" 5/16" 3/8" 7/16" 1/2" - High-Precision Leather Punch Tool for Belts, Fabric and Crafts - Durable Carbon Steel Tools for Hobby & DIY Use

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.

This made my job of making 100 holes for laces so very easy. Suggest a hard cutting board under cutter for material.

Works perfect.

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.

Works perfect with my Bosch electric impact driver.

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.

An FYI to prospective buyers. The 3/16 hole punch bench with the very first use. These are garbage. Do not buy. Very poor value. Metal is way too soft.

These are awesome and made my life much easier! I used them to cut holes in canvas for installation of grommets. They made the process fast and easy.
