I find that they work best on my rotary tools at medium to medium RPM, anything in the high RPM range will cause them

That must be a zero star. I just can't understand how you can drill holes in sinks with these "diamond drill bits". I've tried a few bits but haven't even made a dent on many different shells. Instead of holes, I see dark gray dust forming around the bits. The diamond dust will probably flake off the bits instead of making holes. ended up going to the hardware store for microbits and they made holes in the same projectiles that these "diamond bits" couldn't make. Since the holes are made with…

Great deal, lots of good parts at a very reasonable price. with a regular grinder. Ball drill bits are also great for drilling holes in glass. Haven't used the conical tips yet but they should work fine for etching/engraving. I find they work best if I cut off the bottom of a 2 liter bottle, fill it with water and sand down my piece while it's done. immersed. I use a flexible shaft to keep the water out of the way of the rotating tool and eliminate the risk of electrocution. When you first get…
