Master Cut (Double Cut) Fine Cut RHS The WIDIA exclusive master cut, with its chisel-type cutting The WIDIA fi ne cut right-hand spiral is used in applications edge, is a machine-ground tool built to exacting tolerances where stock removal is light and workpiece fi nish is critical. of concentricity, size, and shape. This accuracy, when A greater number of fl utes reduces chip load and provides combined with precision grinders, results in smooth-running, excellent control in deburring small, intricate areas. fast metal removal, and fi ne fi nishes. The right- and left-hand Available as specials. helical fl utes combine to produce a chisel-type cutting tooth. This results in faster penetration and stock removal with minimal bounce or chatter. The master cut design also produces an easy-to-handle granular-type chip in most metals, as opposed to the conventional sliver-type chips. Throughout its life, the master cut gives faster stock removal and less operator fatigue, and maintains a good fi nish on the widest possible variety of workpiece materials.

Aluminium Cut The WIDIA aluminium cut burs are outstanding on soft or non-ferrous type materials. Use the aluminium cut design on aluminium, magnesium, brass, lead, and most plastics.
