    General Purpose Grinding Wheels for Angle Grinders—Use on Metals

    Image of Product. Front orientation. Contains MultipleImages. Grinding Wheels. General Purpose Grinding Wheels for Angle Grinders—Use on Metals.
    A good value for everyday use, these wheels offer an economical balance between heavy material removal and long life. They are also known as Type 27 wheels, raised-hub wheels, and grinding discs.
    Wheels are aluminum oxide, which is the most common abrasive used in grinding metal. Use for grinding surfaces and removing weld seams. The 1/8" and 3/16" thick wheels can also be used for notching and cutting.
    Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

    Long-Life Grinding Wheels for Angle Grinders—Use on Metals

    Image of Product. Front orientation. Contains MultipleImages. Grinding Wheels. Long-Life Grinding Wheels for Angle Grinders—Use on Metals.
    Wheels are a blend of aluminum oxide and zirconia alumina, which removes more material and lasts three times as long as our General Purpose Grinding Wheels. They are also known as Type 27 wheels, raised-hub wheels, and grinding discs.
    Wheels are designed for grinding metal surfaces and removing weld seams. The 1/8" thick wheels can also be used for notching and cutting.
    Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
