No matter where I set the bit clearance, no matter how fast/slow I feed
the bit, and no matter how deep I go per pass, my bit clogs with
material almost instantly.

Any help would be mondo appreciated!!


You have to hone the chisel and sharpen the bits.
On a stone, smooth the outside of the chisel. One the inside, Lee Valley
has a tool for sharpening it. It is a cone shaped wheel. Take a small file
to the bit and file the same angle as on the bottom of the cutting blade and
on the side.

If you don't do these two steps, you will never get a good mortise. There
may be better chisel and bit sets around but these as they come from the
factory are crappy.
