STC ROUTER CUTTERS

Finishing Spiral
Three Flute Downcut STC

A range of three flute downcut spiral cutters, which give high feed rates with
fine surface finish. Downcut spirals give better hold-down when working on
vacuum beds but require efficient extraction as the cutting action pushes the
cut material downwards.
A limited range is available in LH (anti-clockwise) rotation.
