I've been looking for a set of metric counter-bore cutters for cap screws and I'm befuddled by the options. What to choose for "general use"?
2 flute, 3 flute, 4 flute? KEO has fixed pilots but come in three different sizes?
Before thread, Fine, Medium. So I guess you have to decide if you want to cut all your counter-bores before or after threading the hole all the time? I'm certainly not going to buy three different sets, that's for sure.
How do you guys deal with it?
My Enco set of Imperial counter-bore cutters came in one size pilot diameter. Take it or leave it.
