FIELD: process engineering.
SUBSTANCE: cutting tool comprises cutting parts with back angle composed by cutting supports with side surface there between. Note here that every separate cutting part on the other cutting edge has symmetric cutting part with common cutting diameter arranged on the other cutting edge. Said side surface features length larger than or equal to width of appropriate cutting edge while periphery of separate cutting part, nearby the axis, is arranged sp that the start of separate cutting part nearby cutting edge periphery is located more close to the axis than periphery of cutting part nearby the axis. Cutting tools arranged in symmetry in different directions from the axis of different coordinates are located in different cutting planes. Note here that separate cutting parts feature width smaller than 1/7 of cutting tool diameter+ Note here that separate peripheral cutting part can feature cutting width smaller than 0.1 mm.
EFFECT: higher heat resistance, decreased cutting forces, higher precision.
