Result and comparison basis
At 250 m/min high-speed continuous turning of HRC 60 steel, the coated KBCN5010 grade showed the least flank wear of the three compared grades.
Comparison basis: Three competitor reference grades under identical high-speed conditions.
Comparative data from Koves internal cutting tests and customer field applications. Competitor grades are anonymized as reference grades. Results depend on workpiece, machine and setup; validate on your own production before adopting parameters.
