Hi Terryd,
I have also coloured the tops of the flutes of all drills and taps and a dab of colour on all dies, same side as size stamping. Funnily enough, my Metric gear has been coloured red same as you did. BA =white. ME32T=blue band. ME 40T=blue and yellow bands.
BSW=orange band. BSF =red and yellow bands. Brass 26T = yellow band.
Metric drills=red. No. series=green. Letter series= yellow. Fraction series unmarked.
When I get around to it, I will colour my Metric endmills and slotcutters red, leaving Imperial sizes unmarked.
Many moons ago, drills came chemically(?) blued with a silvery band on the shank where the size was clearly stamped. Now, metric drills come all over matt black, badly or illegibly stamped with sizes if stamped at all. Have the beancounters banned “quality”?
My back entrance gate, outhouse both have coloured padlocks, together with the 2 on my workshop door, all with matching coloured keys. So much quicker and more convenient.
Regards,
John
