The Rottluff Premiumflex ZK 40 combines zirconium abrasive grains with a durable flap-disc construction to provide high stock-removal performance and a consistent grinding action. Zirconia-based flap discs are particularly suited to demanding metalworking because the abrasive can maintain a strong cutting action as the disc wears.
With a 115mm diameter and 22.23mm bore, it is designed for compatible small angle grinders. The coarse 40-grit specification makes it suitable for heavier grinding and preparation work rather than fine polishing.
