    Miniature Multipurpose Grinding Bit Sets

    Image of Product. Front orientation. Grinding Bits. Miniature Multipurpose Grinding Bit Sets .
    Best for intricate, precise grinding jobs on metal, ceramic, and plastic, these sets include diamond abrasive bits with different head shapes. Their 3/32” diameter shank and small head make them great for tasks with fine details.
    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.

    Image of Product. Front orientation. Grinding Bits. Rubber-Cushioned Abrasive Grinding Bit Sets for Metals.
    The bits in this set have rubber blended into the abrasive, which cushions during grinding to produce a smooth to extra-smooth surface texture.
    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.
    Aluminum oxide bits are for grinding hard metals.
    Silicon carbide bits are for grinding soft metals.
