FIELD: process engineering.
SUBSTANCE: invention relates to grinding and can be used for cutting of solid materials, in particular, to sawing by wire. Claimed article comprises elongated body, binder ply on the surface of the latter, abrasive grains contained in said binder with the mean concentration thereof varying from approx 0.02 carat/m to approx 0.30 carat/m. Note here that abrasive grains are selected from non-Gaussian grain size including at least two different mean grain sizes.
EFFECT: higher wear resistance, longer life.
