SBN K-TIP is morphologically featured in that cBN grains constitute

the skeleton with special binders filling voids and creating coherent bonds.

Use of SBN K-TIP is recommended for the purpose of

cutting hard ferrous alloys and difficult to work materials

and for a raw material of wear resistant part.
