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…

Rock drilling for jewelry
Better than some others I have tried

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.

Gets the job done.
Love these. I bought one high dollar diamond to drill bit and it wasn't near the quality of these. I use to drill agate. Great price. Great product. Will buy again.

Worked like a charm.
Needed to clean out the holes of some 1.5" long beads that were not fully drilled. Put a little water in each end for cooling, then drilled with an Hitachi cordless rotary tool. The bit went through very nicely. After three beads the bit still looked like new.

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.
