10 Pcs Diamond Burr - 3/32'' Shank Cone Shape Diamond Burs Stone Carving Bits for Rotary Tools includes Dremel (D Type)...

I wanted to poke holes in sea shells for my kids to string them on necklaces. worked good for that, just dont press too hard and let the bit do the work, keep it wet while drilling.

I'm writing this review mostly because I'm tired of reading reviews that state "won't work with Dremel" on various bits/burs sold on ZeeBooth. These have smaller shafts than the traditional Dremel bits, which means you will use a different collet than the one Dremel tools usually have installed from the factory. Depending on your tool, you should have gotten more than one collet. Look at the accessories that came when you purchased your tool. If nothing else a quick Google search for Dremel collet will educate you on what needs to be done to make these bits work with your "Dremel" tool. As for these things... They are good you get a nice selection of sizes. What I really like is the smaller diameter bits .5 & .8 aren't blunt cut at the tip they come to a nice point. They are delicate don't try cutting through metal... Also if you wet them before each use it helps extend the life of the diamond coating. They aren't meant to last forever. They are best for detail work.... I would like to by the smaller ones in bulk. Unfortunately when looking to purchase these specific shapes in bulk I've had no success....

Rather small bits

Perfect for pottery! These made quick work of some holes I accidentally filled with glaze, much more cheaply than other big name *cough* Diamond brands. Great value.

These will not fit in a dremel. I put one in, it fell right out. Shaft is to thin, waste of money.
