FIELD: machine building.
SUBSTANCE: diamond cutoff tool comprises a base from metal wire with a functional layer of diamondiferous material. The base is provided with the longitudinal grooves of rectangular cross-section in which the functional layer is laid. The depth H of each groove amounts to (1/10-1/3)A, where A is the average diameter of diamond grains of main fraction. The number of grooves Zk is chosen according to a certain dependence.
EFFECT: console fixation of diamond grains on the base of a diamond cutoff tool which provides for longer service life of the latter.
