I needed to put holes in magnetic sheets, like bumper magnets. My sheets were extra thick and a standard drill bit destroyed them. Found these and hoped they worked. First, unlike everything else I've ordered lately, these arrived on time. Packing is terrible and the set is loose in a small baggie. The punches are solid steel and fairly sharp, and when put in a drill press, worked great. I put an extra layer of sheet material on a wood block to protect the bits. Again, they worked good. They tend to "swell" the hole slightly as they cut, but the hole is smooth. Time will tell about durability and They may be difficult to sharpen. So far, very pleased and really grateful they actually delivered as promised. A concept other sellers could learn from.

There may be easier, faster, or better ways of creating holes for grommets but these are the best I have ever used. Clean, sharp, smooth, and perfectly sized, I’m sold on this product for life! Could you please package a “duh” preventative with these, though? Managed to catch part of the main project under the place I meant to make my hole and guess I’ll remember forever more to watch for that “duh” error! Great product and good price.

Along with this set of fabric/leather hole cutter bits, I have grommet kit from General Tools with a manual (hammer-driven) punch. That punch has a sharper edge than any of the bits in this hole cutter set. I was cutting a 3/8-inch hole in two canvas bags; one with double-layer canvas, and the other with triple layer reinforced canvas. I was able to get the job done with the 3/8 inch hole cutter bit. I did learn that it is crucial to focus diligently on the bit drilling into the canvas; if you lean the bit away from the perpendicular axis (away from 90º perpendicular to your work surface), the bit will fail to cut the canvas on one side of the circle. Not a show stopper but it is crucial you maintain a perpendicular drilling posture with your drill and bit.

These items were obtained to assist with installation of retaining clips for our vehicle mats. We encountered no issues drilling the pilot hole so we could expand to allow clip installation. We would recommend as they efficiently drilled cleanly and neatly.

very cheap, 3/16' broke first usage

Totally life changing. Clean, easy neat holes. perfect fit, can go through MANY layers of jeans or PU leather, or whatever, can do even two pieces with multiple layers at once to line up holes. How did I ever live without this laboriously exacto knifing holes that still were messier.... Also, these are fully as good as more expensive versions that they sell on sailmaking websites. BUY THEM NOW!.

The media could not be loaded. As I age, it is more and more difficult for me to deal with grommeting for my corsetry and costumes. I bought a grommet press last year and just found these so that I don’t have to cut my fabric or try to stretch the fibers over the grommet. I popped this in my impact driver and it worked a charm on three layers of cotton canvas. Brilliant and easy.
