Small Diamond Core Drills

nicely made

These are good quality diamond tubular or core drills. My only complaint is that, because I use them in a small drill, I have to cut the long shanks back by one half - I don't understand why they are...

These core drills are great for tiny holes in glass.

Did the job as adavertised.
