Okay if you want to drill through hardened steel gun pieces. These are your bits. They cut through hardened blued steel fire arm parts like they are butter. NO OTHER BITS NOT EVEN DIAMOND CAME CLOSE TO EVEN MAKING A MARK. I ordered several more in different sizes. I will never use any other kind of drill bits but these for any kind of gunsmithing

This item is simply worthless. I tried to drill small holes in a thin piece of metal, ended up breaking 3 bits!

I bought these to drill pearls. The tips would break off and get stuck, which ruined the pearls. Definitely do not recommend these based on fragility and the waste of materials.

For dense plastic models. This size bit snaps easy. Nice to have very sharp size bits in stock.

Well made, sharp PCB drills.Best if used with CNC feedrates. Of course, very fragile because they're carbide.Money well spent!
