Vap, how did you manage to spend 40 on a M3 HSS tap? You guys are supposedly Metricified since '88 so that shouldn't be a rarity. I got a 3 piece set for M3 and it was something like $6 which was seemingly outrageous as I later picked up a M3-12 tap die set (el cheapo) and doubt I spent more than $9.
And, I'm farther than you from China and we have Eurotaxes. Are you getting the fancy stuff?
Nice job all around, and on the groove ingenuity.
LoL, $40 was for a 3 piece set with each one a different profile and of the highest quality I could buy. I live is a small town of about 7,000 so that has a lot to do with price and availability.
Thanks for the kind words though
