Bought these to fix my dog’s unruly nail - he has one that has grown wild and the vet has not taken care to help fix it. So I bought these to fix it myself. Turns out, these are awesome nail trimming bits!! I use my normal dremel on 10-13,000 and carefully trim. His nails are looking better than ever! The bits are a nice length (not too long like some other Chinese bits) and work great.

They work like they should and sharpened my Ryobi electric mower blades.

I had to remove some edges of a ceramic tile where a water line would be near it. I didn't want the outside of the pex water line rubbing the tile, so this was great to take 1/4" off the tile in no time. 60 grit removed tile material quick and still left a nice edge finish. Now I don't have to worry about a future water leak. Very useful little diamond burrs, I'm sure I'll fine more uses for them.

I use these to work plastics and they perform very well for that purpose.

Work great for cleaning out the thin set between tiles. They also do minor shaping of tile edges with minimal effort.

All of these bits were too big to fit into my nail drill.

These bits are super aggressive. Will chew through just about anything. Very durable. Highly recommend.

The grit didn’t last very long. But considering they’re fairly inexpensive - you get what you pay for. I use them to smooth out the edges of my wood carving. They might work really well on a softer material… But I don’t recommend them for woodworking

Performed well and as described in my applications. Worked well on hard metal and trimmed dogs nails quickly without heat buildup when used correctly

Why advertise 10 pieces if it's only 5?
