    Grinding Wheels for Straight Grinders

    Image of Product. Front orientation. Grinding Wheels. Grinding Wheels for Straight Grinders.
    Use these wheels for heavy material removal in one spot or along a weld seam. They are also known as Type 1 wheels and snagging wheels.
    Wheels are aluminum oxide, which is the most common abrasive used in grinding metal.
    Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

    Heavy-Removal Grinding Wheels for Angle Grinders—Use on Metals

    Image of Product. Front orientation. Contains MultipleImages. Grinding Wheels. Heavy-Removal Grinding Wheels for Angle Grinders—Use on Metals.
    A large grinding surface, combined with a thick layer of rough abrasive removes more material than other wheels. They are also known as Type 11 wheels, flared-cup wheels, snagging wheels, and cup stones.
    Wheels are often used to grind weld seams and remove flaws from castings.
    Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
    For Steel—Wheels for steel are aluminum oxide, which is the most common abrasive used in grinding metal.
    For Steel and Stainless Steel—Wheels for steel and stainless steel are zirconia alumina, which grinds faster and lasts longer than aluminum oxide.
    Full Backing—The full backing provides additional support.

    Quickly remove vinyl, decals, tape, and double-sided molding striping and trim without damaging the surface below. These solid, molded wheels use friction instead of abrasives to prevent scratches and damage. Since friction creates heat, you should not use these wheels with heat-sensitive surfaces.
    Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

    Wheels remove more material than other grinding wheels with cotton laminate.
    A combination of cotton laminate and aluminum oxide abrasive creates a smoother surface than other grinding wheels with similar grits. Wheels are also known as Type 1 wheels and snagging wheels.
    Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

    Wheels have a large surface area and a thick layer of rough abrasive for heavy material removal on concrete and stone. They are also known as Type 11 wheels, flared-cup wheels, snagging wheels, and cup stones.
    Wheels are silicon carbide, which won't generate much heat.
    Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
