Re: Drill bits
I have a complete set of Dormer drills (1 - 60, A -Z & 1/64th to 1/2 inch) that were my late fathers and all of them are as good as when they were purchased. I have had to renew a few of the smaller number and fraction drills with Dormer replacements owing to the odd breakage and have never had any problems with them. I do sharpen them when they are blunt of course.
I do not have any metric drills as most of the things I work on are old and use imperial sizes anyway. Also part of dads kit are a set of number 61 - 80 drills but being so small I have never had to use these. All the above are HHS Jobber Series.
