The HeliPlan system from Leitz is a planer head constructed with the interface and cutter block in one piece (monolithic). The spiral arrangement of the cutting edges results in a “soft” contact, designed to provide decreased noise levels, and reduced cutting and feeding forces. The concave-ground cutting edges avoid tear-outs, so the tool can come very close to final tolerances so finish planing requirements remain small. Cutting edges are carbide, with the potential to be sharpened four times.
