Negative Rake Carbide Tipped Cutters

Rake is the angle of a tool relative to its cutting surface, and most turning tools have a zero (or neutral) rake. These tips have a negative rake, so the face of the cutting tool slopes away from the cutting edge. The geometry makes a cut less aggressive, therefore safer; the negative rake angle virtually eliminates chatter and chipping. It's physics: a negative rake simply can't catch. Make sure your selection is for a mini or a midi tool!
