    Bench and Pedestal Grinding Wheels with Rubber-Cushioned Abrasive for Soft Metals

    Image of Product. Front orientation. Grinding Wheels. Bench and Pedestal Grinding Wheels with Rubber-Cushioned Abrasive for Soft Metals.
    The silicon carbide abrasive in these wheels is suspended in rubber for a cushioned grind with light material removal.
    Silicon carbide cuts through soft metals without generating much heat or causing material buildup.
    Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

    The abrasive grains in these bits are blended with rubber, which cushions during grinding to produce a smoother surface texture than other bits with similar grits. 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.

    Grinding Bit Sets for Metals

    Image of Product. Front orientation. Grinding Bits. Grinding Bit Sets for Metals .
    Each set contains a selection of grinding bits. All include bits made of aluminum oxide, which is the most common abrasive used for grinding metal. These bits are also known as mounted points and die grinder bits.
    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.
    For Steel, For Stainless Steel, For Aluminum, For Brass, For Bronze, For Copper, For Iron, and For Nickel—Sets for steel, stainless steel, aluminum, brass, bronze, copper, iron, and nickel contain bits made from a range of abrasive materials in different shapes and sizes. They’ll help you achieve varying levels of finish on a wide range of materials. Cotton laminate/aluminum oxide blend bits remove more material than rubber-cushioned aluminum oxide bits, and they’ll create a nicer finish than vitrified ceramic alumina bits. Bits with nylon mesh remove the least material but create the nicest finish.

    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.

    Made of cotton fiber layers embedded with aluminum-oxide grains, these bits grind and finish in one step. They’re ideal for light deburring, blending, and finishing metal. These grinding bits remove material more efficiently than rubber-cushioned bits. While grinding, they resist the buildup of aluminum, brass, bronze, and other nonferrous metal. They’re 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.

    Bits attach to shanks so you can quickly switch head shapes without removing the shank. The abrasive grains are blended with rubber, which cushions during grinding to produce a smoother surface texture than other bits with similar grits.
    Bits are silicon carbide, which cuts through soft metals without generating much heat or causing material buildup. 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.
