The optimum mode of drawing of a covering on which the experimental batch of cutters is prepared is established and tests for their firmness are conducted. On operation of turning of pigiron sleeves of cylinders of diesel engines firmness of the tool with a covering has raised in 1,7–1,8 times in comparison with a covering from carbide of the titan.
