SI FANG 30Pcs Diamond Grinding Stone Carving Drill Bits, 1/8" Accessories

Excellent value. Used to grind on a bathroom concrete floor in hard to reach areas where a molding typically covers up. I made a pass over all four wall edges. Say 15min of use lightly grinding concrete. The bit held up and has more life left.

I was tired of using disk after disk of sand paper on my rotary tool for dog nails. This is working like a charm so far. Removes quick before heat can build up and irritate the puppers.

Used to grind out a steering part that had rusted bad. Good job!!!!!!!!!!!!!!!!! by ---HERB THE POWERMAN ---

I love these bits for my Dremel on resin crafts!

I purchased these bits to use on limestone sculptures. Takes stone off like it was balsa wood. No issues with over heating but five bits have randomly bent in the pencil grinder (running) while I wasn't grinding and was just holding the tool. Otherwise good product.

Using with my rotary tool and have only had to use one bit so far and have done multiple stones from quartz to jasper. Great value for the price. Will order again.

Great for working with fired pottery.

These worked great grinding down glazed pottery. They are very durable. Well worth the money

They are a little bigger than I thought, but they work great. I don't know how you can get so many for such a good price! Very happy with my purchase; I use them for carving in stone.

Have used some of the bits to carve addresses in two hard rocks and they worked well.

Get exactly what you pay for!
