Hi there Sonnie,

here's what I use:

A narrow straight bit used for:
- plunge cutting openings in shelf braces
- cleaning up edges of panels that have been cut slightly oversize with saw
- cutting driver openings
- cutting undersize port openings

A wider straight bit used for:
- Cutting driver rebates

A flush trim bit used for:
- Cleaning up overhang from joints
- opening up port holes

A rollover bit used for
- Cutting port flares
- Rounding off edges if cabinet is not to be veneered
- Edges of grille frames

A 45 degree chamfer bit used for
- Opening up around deeply recessed amps
- Edges of grille frame

Some of the straight bits could be duplicated with spiral upcut bits which pull the cut material out of the work area

regards
Collo
