I never have and never will write any reviews for any kind of compensation. Every review is an honest opinion based upon my personal experience with a product I have purchased:I do some lapidary as a hobby and make my own gifts for friends and family. I have included a picture of a few of the stones I drilled with my bits. I have drilled obsidian, jade, aventurine, amazonite, quartz, labradorite, tiger eye, and more with no problem. Have fun😎

I'm not gonna lie, when I opened the package I thought what am I supposed to do with these little needles. Decided to give them a try before jumping to conclusions. Best advise from other reviews, slow and steady. Not a lot of pressure.They work great on the sea glass I'm working with.Pleasantly surprised!

It’s a good value for the money! Once I learned the best pressure to keep them from snapping off, I usually get several crystals drilled per bit

These drill bits were flimsy and useless.
