Looking to invest in a "shelix" type cutter for pattern cutting on my shaper and need suggestions. Spindle is 1 1/4". I would like to be able to flip the head and feed from both directions. If I buy a Byrd head it will be down cutting spinning one way, and when fliped, it will be up cutting. Not good.. Do they make a left & right spiral head? Should I consider a different head, that has staggered teeth, but not a shearing cutting edge?
