    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.

    Grind a variety of materials, from metal to ceramic and plastic, in precise, detailed jobs. These bits have a diamond abrasive, so they’re extremely hard. Their 3/32" diameter shank and small head allow them to get into intricate spots. They 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.

    Long-Life Rubber-Cushioned Abrasive Grinding Bits for Metals

    Image of Product. Side1 orientation. Grinding Bits. Long-Life Rubber-Cushioned Abrasive Grinding Bits for Metals.
    A diamond abrasive that's bonded to a rubber cushioning makes these bits last 10 to 20 times longer than rubber-cushioned bits without diamond. Because they’re cushioned during grinding, these bits produce a smoother surface texture than other bits with similar grits. 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.

    Made with diamond abrasive, these bits are extremely hard and last longer than tungsten carbide. They have a small shank and head for precise and intricate jobs. To extend the life of these bits and improve their finish, use a water- or oil-soluble mist or coolant. They 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.

    Produce a smooth surface on precise, intricate grinding jobs. These bits are cushioned by rubber, so they create a smoother finish than other bits with similar grits. Made with a diamond abrasive, they last 10 to 20 times longer than rubber-cushioned bits without diamond. Their 3/32" diameter shank and small head allow them to get into intricate spots. 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.
