Result and comparison basis

Machined 1.5 times the number of parts of the previously used grade with better surface finish (Rz max 4.8 μm) at 0.35 mm/rev feed.

Comparison basis: Previously used grade.

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.
