Meaningless answers to an unanswerable question. They last until they're
too dull to plane the kind of wood you have to plane at the moment. Might
do the next variety well, but that's a horse of a different color.

I work almost exclusively with qs white oak. I dont think I've ever paid
attention to how many bf I'm getting out of my planer blades, but I'll
guess
between 75 and 100 board feet, depending on my depth of cut.

That 75-100 board feet guestimate is with roughsawn lumber and planing
it
only enough to bring it to a smooth finished surface. I say guestimate
because it could be half that much or twice as much.

Wow. That seems really short. inless you are referrring to the actual
VOLUME
of material removed. I'm referring to 100 bf being processing 100bf of
rough-cut stock , 4/4 or 5/4 into nominal S4S.

My cumulative guess over a halfdozen blade changes on a delta snipe-master
and a DW733 is a few hundred bd ft.
