It is intended for high productivity rough machining of hard material,<br />
especially steels. The innovative formula and composite synthesis process<br />
allow manufacturing <strong>tools</strong> that substantially increase productivity both<br />
with turning machining and with milling and that have high impact load<br />
resistance.<br />
MBR 7010<br />
Microhardness, kgf/mm2 – 6500<br />
CBN content, % - 85...90<br />
Grain size, nm – 300…800<br />
It is intended for finishing and superfinishing of cast irons, tempered steels<br />
and superhard materials including composites and materials based on<br />
tungsten and cobalt. The MBR 7010 tool superhard <strong>cutting</strong> edge ensures<br />
the highest quality of surface to be machined and high wear resistance.<br />
