Customer Reviews:
Awesome Set! 
Been using this for my rotary tool and they’ve been great! Make sure to cool off the bits in water every once in a while during long use and they’ll last a lifetime(or at least a long time).
OK for soft materials 
The drill bits worked fine on soft materials such as seashells as long as I didn’t put too much pressure on the bit. But on harder materials such as ceramic or stone, the diamond coating wore off very quickly, rendering the bit useless. And yes, I did use lubricant.
Pro-Quality 20-Piece Diamond-Point Bit
Very nice drill bit set. Seems to be of good quality.
I am using the diamond bits to drill semi-precious gems.
One bit has lasted three gems, so far.
A must buy for Crafty people.
One of these diamond tipped bits will run you between $8.00 - $10.00 at any retail or hardware store. This set has every bit for any project you could think of and the power to handle almost any material. It is definately worth the money. Works great on glass, metal, and stone.
I am very very satisfied.
