Description

The Pearl Abrasive Greenback™ Zirconia Maxidisc™ (MAX4540ZG) is a premium trimmable flap disc designed for high stock removal and long service life. Its standout feature is a trimmable nylon backing that allows users to shave off the edge of the backer as the flaps wear down, exposing fresh abrasive material and extending the disc’s usability.
