The results of physicochemical and mechanical investigations into the properties of the boron– alumina–silicate glass system, designed for cBN tools with additions of submicrocrystalline sintered alumina (cubitron), have been presented. Four glasses, obtained by the fritting method were investigated by the following experimental techniques: differential thermal analysis (DTA), infra-red spectroscopy, microhardness (3.58–4.48 GPa), bonding strength (36–41 MPa), thermal linear expansion coefficient (TLEC) (5.5–7.36×10–6 1/deg), wettability on electrocorundum, cubitron and cBN substrates (q < 28°). The glasses fulfilled all the criteria of usability.
