Diamond Drill Grinding Bit Set, Stone Carving Rotary Tools Polishing Kits Diamond-Coated with 1/8-inch Shank Universal Fitment for Stone Glass Ceramics

perfect, price is right, easy to use, fits great, and the quality is well made

These work great for a variety of uses. I will definitely purchase these again.

Event hough they were smaller than expected, they work well

The obvious durability and the variety make these a one-time, satisfying purchase. I have not used them on metal, but I'm quite certain they'd hold up better than the alternatives littering Amazon.

We did some yard word and added these beautiful black stones but had a bunch left over. They are small, maybe 3-5in but nicely polished. I had seen a stone engraver on Tiktock but since I already had a Dremel, this was perfect. SO many bits all for a GREAT low price. I have engraved about 6-7 rocks and it’s a lot of fun! The bits fit the Dremel perfectly and engrave the rock without hesitation. It leaves a beautiful mark on the stone as the different bits allow it to be fairly wide or fine point. I have only used 1 oval bit really, and so far it’s showing no signs of wear. A great set of bits!

These work but aren’t the best. For the price I suppose they are okay.

Bought these diamond drills to use with my Dre el tool. Fine selection of shapes, and quite durable.

I wanted to etch some memory stones for family members who recently passed away. These bits were just what I needed to do just that. They work great!
