Hello Gentlemen,
I should have been more specific. I was really after HSS. Nigel B seems to have hit the jackpot with the Cromwell drill blanks. These are said to be HSS. But as they are described as drill blanks, I am not 100 % certain. One way to find out for sure I suppose!
Thanks everyone!
Andrew.
If they're hardened and ground all over without back taper, there doesn't seem much room for doubt.
