Комбинированный режуще-деформирующий метчик, отличающийся тем, что, с целью повышения точности и качества поверхности образуемой резьбы, на заборной части выполнены стружечные канавки, которые образуют режущие зубья и деформирующие выступы, что обуславливает улучшение эксплуатационных свойств резьбы за счет поверхностного пластического деформирования.Combined cutting-deforming tap, characterized in that, in order to improve the accuracy and quality of the surface of the formed thread, chip grooves are made on the intake part, which form cutting teeth and deforming protrusions, which leads to an improvement in the operational properties of the thread due to surface plastic deformation.
