I bought a lot of new router bits. Included were 3 Amana straight single
flute bits.

I've never seen a single flute before. Is there some purpose to it, other

In solid surface fabrication, it's the bit of choice for doing cook-top
and sink cut-outs. The single flute throws the waste away nice and quick
without heat build-up. Duane is right; the finish isn't great.
