Hello all,

I have been looking at $80-100 import boring head/bar sets. For that
money, I would not expect to start rebuilding V12 engines, but it would
hopefully teach me a little and tolerate abuse as an adjustable hole
saw. Is that a reasonable expection?

Boring heads appear to be sold by diameter, with no mention of capacity.
Some searching and reading leads me to suspect that one can mount the
bar parallel or perpendicular to the axis of rotation, with the latter
allowing larger holes to be bored. Is that accurate?

Any cautions or advice?

Bill
