    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.

    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.

    Almost as hard as diamond, these tungsten carbide bits cut through nonmetals without generating heat.
    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.
