    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.

    Polishing Bob and Compound Kits

    Image of Product. Front orientation. Buffing Kits. Polishing Bob and Compound Kits.
    Everything you need to polish small areas and hard-to-reach spots. These kits include polishing bobs in different shapes, sizes, and hardness ratings, along with buffing compounds. Use these bobs in a drill or grinder for bits and burs.
    Most buffing processes have two steps, cutting and coloring.
    1. Cutting removes scratches and surface imperfections.
    2. Coloring produces an even finish.
    Cutting/coloring compounds perform both steps at once.
    Wool Felt—These bobs absorb and retain compounds better than synthetic felt bobs, so you don't need to reapply as often.
    Medium—Balance removing material with leaving a smooth finish.
    Hard—For aggressive material removal.

    No-Mess Polishing Bob Assortments for Hard Metals

    Image of Product. Front orientation. Polishing Bobs. No-Mess Polishing Bob Assortments for Hard Metals.
    Keep multiple shapes, sizes, and grits on hand to polish hard metals without any messy compounds. These bobs come embedded with long-lasting diamond abrasive—the hardest we offer. They’re best for cutting into stainless steel, titanium, and other tough materials. Use them to polish small areas and hard-to-reach spots with a drill or grinder for bits and burs. Grit is approximate. Labels in the lid include our part numbers, so it's easy to replenish the assortments.
    Wool Felt—Softer than rubber, these bobs better conform to your work surface and prevent gouging. They're the best choice for final finishing steps.

    No-Mess Polishing Bob Assortments for Reciprocating Polishers

    Image of Product. Front orientation. Polishing Bobs. No-Mess Polishing Bob Assortments for Reciprocating Polishers.
    Keep a variety of rectangular sizes and grits on hand to polish flat surfaces with a reciprocating polisher—no messy compounds required. These bobs are embedded with silicon carbide abrasive, which stays cool to prevent buildup. That makes them best for soft metals prone to clogging, such as aluminum. The abrasive also lets you cut fast without pressing hard. Their flat profile suits both large surfaces and straight, narrow spaces. The bobs have a beveled tip to polish on an angle. Grit is approximate. Labels in the lid include our part numbers, so it's easy to replenish the assortments.
    Polyurethane Rubber—Harder than neoprene and wool felt, these bobs hold their shape longer, even during heavy use.

    Polishing Bob and Compound Kits for Reciprocating Polishers

    Image of Product. Front orientation. Buffing Kits. Polishing Bob and Compound Kits for Reciprocating Polishers.
    Everything you need to polish flat surfaces with a reciprocating polisher. These kits include polishing bobs in different sizes and hardness ratings, along with buffing compounds. The bobs have a flat profile that moves back and forth with the motion of the reciprocating polisher. They’re good for large surfaces or squeezing into narrow, linear spaces. Use the beveled tip to polish at an angle.
    Most buffing processes have two steps, cutting and coloring.
    1. Cutting removes scratches and surface imperfections.
    2. Coloring produces an even finish.
    Wool Felt—These bobs absorb and retain compounds better than synthetic felt bobs, so you don't need to reapply as often.
    Medium—Balance removing material with leaving a smooth finish.
    Hard—For aggressive material removal.

    Best for grinding composites, fiberglass, plaster, plastic, rubber, and wood without generating heat, these sets include a selection of our most popular tungsten carbide bits. The 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.
