Chiloskit 10 Pics Diamond Grinding Bits Rotary Burr Set, 8mm Head Mounted Points Grinding Bit for Stone Carving, DIY Grinding, Polishing, Engraving, 1/8 Shank Suit Most Rotary Tool

Perfect to round off my dogs' toenails after clipping. No sharp edges on them. Long lasting and I have tried many. 4 x 16 nails on five dogs...Do the maths

I use these in my dremel for nails on my two German shepherds and my bully. They last far longer than the barrel sandpaper type Dremel attachments, the dogs don't mind them because they don't chatter like the sandpaper drums do which puts an end to nail shortening. I'll be ordering more!

Good bits for the price and amount recieved. They last fairly well. I'm sure it depends on the material you are using it on. I use mine for stone that has sharp edges and uneven rough surfaces... And I use them ALOT. So I probably put the bits to the ultimate test... And these held up well. My only complaint is that on some of the bits(around half that I bought) wore down to metal(all the diamond coating came off) in only one strip of the bit or just one chunk of it. Which for my purposes, rendered it useless after two or three uses. Again- could be the material I use them on. Other than that they are great. I am ordering my next batch now.

The product is as described, but I thought they'd be a bit stronger. It does the job of dremeling my Lab's nails though!

I do stone carving and these bits do great with water and last. Customer service is excellent also.

I was tired of breaking the stone bits for my dremel and bought these to see if that would be a good substitute. I haven't used them enough to speak to their longevity, but they do work well, and are a good value

Bought these for my rechargeable Dremel to file our dogs nails. The sandstone bits I had were not working well at all. With one of these, I finished her nails in less than a 1/4 of the time and no wrestling. She's a 50lb cattle dog/boxer mix with some hard nails. This was the first use, so not sure about durability. But with 10 bits included, it's safe to say these are going to last me awhile.

I bought these to use in a dremel to grind dog toenails. They were recommended to me for that use. But they did not fit my regular dremel, and on another one that i had they did not work at all as expected. Very disappointed.

These dermal bits work great! They fit both my dremels ( oster and andis)

Needed to widen the opening on a ceramic sink for a faucet. The bit worked flawlessly and got the job done.

Used to polish cut glass

I was a bit skeptical since the grit looked to fine to me but it actually did a decent job on my dog's nails. I honestly don't think they don't burn like the paper ones but looks like the discomfort is definitely less. I like that the head is smaller.. makes handling way easier especially if you have small hands. Fits perfectly on the Oster Pet Nail Grinder. Overall I'm satisfied with my purchase.
