FIELD: woodworking industry.
SUBSTANCE: invention relates to woodworking industry, in particular, to round-sawing machines and other devices for high-efficiency and quality division of wood in longitudinal and transverse directions with increased period of resistance. Round saw for wood with effect of self-sharpening contains housing with cutting edge with teeth and alternating layers of hard and soft material. Layers of soft material are located on lateral and back surfaces of teeth. Ratio of the hardness of the layers lies within limits HB1/HB2=2–3, where HB1 is hardness of the hard layer, HB2 is hardness of the soft layer.
EFFECT: higher durability of saw and broader technical capabilities.
