Don, I coincidentally saw a multi-pack of those on the HF site while I
was looking (maybe a 50pc). It was under $10. They looked like the
refurbs I just bought, which all have eighth inch shanks.
I still can't get over that brand and some of the prices on the larger
power tools at that site. There's an angle grinder in there for $9.95.
At those prices, worst case scenario, some of that crap could be good
for a laugh after it breaks (maybe not immediately afterward).
I'm still wondering if anyone's used a cordless or 12V type roto for
PCB. I'm not sure they'll have them connected for listening. FWIW, my
etched holes and pads are usually enough to keep down any significant
side to side bit play, and I've got a larger press and several power
drills for bigger holes, so a cheap chuck or a tad less power may not
kill me.
-Thanks!
George
PS Don- Just an uneducated guess, but it may be possible that the
resharpened stuff isn't all that much different than new. It sounded
like they're constantly being popped out of high quantity drilling
machines as they dull, and going right back to whomever shaped the
edge to begin with (could be wrong though). I hate to admit it, but
I've gotten lazy and cut with a broken one before. At the PCB speeds,
I almost couldn't tell the difference.
