For drill press only
The bits looked great. Unfortunately you have to use them on a drill press. The description said hand held drill would work.

Need drill press attachment
Very good quality but something you need to know. You need the drill press attachment to use them. Watch video on youtube before buying on how to use

Good product
Product itself could not be used without the adapter which is not mentioned in advertisement. I made my own custom adapter and used these drills several times and was very pleased with the results.
