good bit poor description
Ufortunately it was inadequate for the job I bought this to do as I needed to drill 10mm deep. I wish the desciption had mentioned that the shank was a larger diameter than the flutes. it's a good drill bit however, well ground and a good finish on the holes that were only 7mm deep.
