Drilled my oyster shells and didn’t break!
The media could not be loaded. Perfect drill bits to make holes in various sized and thickness of oyster shells for an art project. After returning another brand that snapped every times, I drilled all these plus a few more using just one drill bit.I am stoked, quality is good and I will get a lot of use out of these with my Dremmel.The photos also show my method of drilling in water to keep the toxic dust down.I hope this review helps you to continue being creative and having fun.

Good quality
These are better than the diamond twist bits that I have been using! Will continue to purchase more

Poor Quality
It was so disappointing to have finally found the drill bits I was looking for, only to receive them and find how poorly they were made. They’re breaking all the time! I should have known better…

Love these for drilling jade, but needle shears over time.
Drills super fast for more holes, and are longer than the hard shaft drill burrs, I just wish the needle shaft was a little thicker, because they shear at the chuck over time with the torque of the dremel so eventually you're left with a good burr head, but no shaft left. Because of this I mount them as shallow as possible each time so they have more shaft left each time they shear.

An unusual application...
I used these to unclog the hollow tubular heating element for a Hakko desoldering tool. The heating element is no longer available, so repairing is the only option. Slow and steady with a Dremel tool worked.

Love these
What was I doing putting off ordering these?! They’re perfect for widening holes in my pendants for when I need to string the cord through instead of adding a bail. I’ve done 10 pendants and the bit is still fit to keep going. Ebony wood is a pretty dense wood that my regular bits have trouble with I’ll be ordering more in the future
