I had a stone countertop I needed to drill into to install a small screw to hold my dishwasher in place. None of the other drill bits I tried could do it, but these did. And it's a good price.

I needed to drill some holes in the bottom of my ceramic bowl that I made. The key with ceramic is to soak the bowl in water for an hour before drilling. That way you don’t crack the ceramic! These drill bits were exactly what I needed to drill precise holes without breaking the bottom, and the holes drilled out very cleanly! A great set of bits for all of your drilling needs!!

These Diamond Drill Bits seem to be of good quality. I use them for carving limestone for my driftwood sculptures. I'd rather the shank wasn't painted.
