What are you guys using for drill bits for pinning, bottle bosses, whatever? I've been using Enco import bits for pinning, jobber length, don't remember what angle, black oxide; not too impressed, they seem to dull very quickly, break easily. I'm about to freshen my supply and am leaning towards 135 degree split points, screw machine length, black oxide, Enco again, possibly Hertel brand (import, or domestic)

Even the larger sizes for bosses (std bits from Lowes or Home Depot) walk enough to annoy (yes, even after spotting) so I figure I'll use the same type as above....or just use spotting drills.

Or would straight flute, stub length be the ticket, or perhaps something else?

Interested in feedback, recommendations, reactions.
