Iām using these bits as setting burrs, and a preliminary test prove to be a positive one. Great value. Arrived promptly.

3/32 shaft is really hard to find, works great, better than expected.

These diamond bits arrived as expected. They are just the right size for starting my drill holes on my gemstones. I love them

Size is good for what I wanted. Wears out fast. I would not purchase again. One bit on etching one glass and it is done. I have others and they do not wear out this fast and were less expensive.
