Indeed. The LV description of their sawtooth bits seems to indicate that
they *won't* drill a completely-flat-bottomed hole:

"Both styles have slightly sloped chipping bevels so that bits ride a
shallow cone of wood to keep them boring straight. Center brads can then
be shorter, increasing bit versatility in thin material."

You're right, Doug...I didn't see that part. However, that may be
because I was reading the other page on their forstner bits, where they
specifically say, "The bit gives a cleanly cut, flat-bottomed hole
ideal for plugging."

Then even show a picture of a perfectly flat-bottomed hole as a
feature.

Regardless, I don't know who the hell would knowingly buy a forstner
bit that drilled a volcano-bottomed hole into a board, so these will go
back.

This is the second time I've found an error in the specs/descriptions
Lee Valley provides in their catalogue. On their low-angle block
plane, they advertise the blade as being a 25-degree bevel. In
reality, it's a 23-degree bevel with a 2-degree micro bevel. I found
that out when I bought their MKII sharpening jig, only to find it
didn't have a pre-set angle to sharpen their own blade. That certainly
wasn't a big enough deal to warrant a return, but the volcano bits are
going back.
