These spiral cutterheads with straight edge reversible knives cuts smoother and quieter than the cutterheads with one length straight blades. If one edge of the inserts is broken or dull, you untigten the screw, turn the edge to another egde, tighten it to the seat.

Replace only the inserts when all four edges are dull or damage.The short length knives also greatly break up cutting forces and the cutterheads require less horsepowerof your woodworking machines.
