CB7925 contains 75% CBN in a ceramic binder. It has a bimodal CBN grain size distribution with a mix of large and fine CBN grains (4 & 12 µm). The main application area is high alloy cast irons but this grade will also perform well in turning of hardened steel and cast iron rolls. CB7925 CBN inserts are only available in solid format.

Recommendations on inserts for hard turning

Be prepared for sticker shock with the CBN insert and that price is for one cutting edge/tip. If there is any interruption in the cut its going to suck big time, they don't like to be pounded. Been a while since I have looked at specks but ceramic inserts are capable of hard turning as well up to a certain range then CBN takes over.

Because the cost of cutting inserts is relatively low—typically just 3 percent of total machining costs with carbide inserts and 5 to 6 percent with CBN—using cheaper inserts may be a false economy. Advanced material inserts can pay for themselves in shortened cycles times or more good parts per shift.
