    Remove material more quickly than other arbor-mount discs. These have precision-shaped abrasive that cuts easily and reduces heat to prevent wear. The grains continually fracture to expose fresh cutting edges while keeping their engineered points and angle. These discs fit over your tool’s arbor for the most stable mounting and require a backup pad.
    Fiber Abrasive Backing—The stiff backing lets you apply maximum force on flat or angled surfaces without the disc collapsing or tearing.
    Ceramic Alumina Abrasive—The sharp edges cut quickly for efficient material removal.
    Threaded Arbor Hole—These discs don’t need a nut to secure, so they're quicker to change out than unthreaded arbors.
    Flat Disc—The standard shape.
    Grit—The lower the grit number, the rougher the finish and the duller the appearance. The higher the grit number, the more polished the finish and the more satin or mirrored the appearance.

    The precision-shaped abrasive on these discs quickly penetrates hard metals and reduces heat to prevent wear. The grains continually fracture to expose fresh cutting edges while keeping their engineered points and angle. Twist or snap the connector on the back to swap out discs in seconds. Choose the connection style that matches your tool or backup pad.
    Cloth Abrasive Backing—Resist tearing and hold up to wet sanding better than paper-backed discs.
