Article is devoted to increase of operability of the samples made of heterogeneous materials. The samples subjected to unilateral cementation, especially when the cemented layer is squeezed, received: 1) significant increase in working capacity; 2) strong clearing of damped oscillations; 3) almost double increase in internal friction. Thus, samples with unilateral cementation possess the increased resistance to fatigue failure at emergence of resonant fluctuations in use. Results of the carried-out tests and the developed manufacturing techniques heterogeneous staly, allows to use them as the cutting tool for woodworking, meat-processing and other areas of the industry for cutting of nonmetallic materials, such as a tree, paper, plastic, slate, etc. In the woodworking industry it is possible to use for production of saws, in particular round saws. The saws made from alloyed stale (9HF) have low hardness 41 … 46 HRC as they are required to be parted therefore are quickly in a stupor. Heterogeneous materials allow to increase the hardness and firmness of the tool considerably
