    The diamond abrasive in these bits is extremely hard and lasts longer than tungsten carbide. For longer tool life and improved finish, use a water- or oil-soluble mist or coolant.
    Bits are also known as mounted points and die grinder bits. Head diameter is measured at the widest point.
    Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

    Similar to diamond, boron nitride is harder than aluminum oxide and lasts longer. Bits are also known as jig grinding pins and mandrels.
    Head diameter is measured at the widest point.

    Adhesive-Back Sanding Discs for Masonry, Ceramics, and Composites

    The hardest of all abrasives, diamond is the best choice for extremely hard materials. These discs cut quickly and wear slowly when sanding masonry, ceramics, and composites. Press them onto sanding tools or backup pads for a hold that won’t slip. To ensure the best bond, clean the pad with a mild alcohol—avoid harsh solvents such as MEK and acetone that can damage the adhesive. Also known as PSA discs.
    Cloth Abrasive Backing—Resist tearing and hold up to wet sanding better than paper-backed discs.

    The hardest of all abrasives, diamond is the best choice for extremely hard materials. These discs cut quickly and wear slowly when sanding masonry, ceramics, and composites. Their unique abrasive pattern prevents material buildup and leaves a consistent finish. The connector on the back lets you swap out discs in seconds. Choose the connection style that matches your tool or backup pad.
