Rubber-Cushioned Abrasive Grinding Bits for Metals


Style 1	Style 2	Style 3	Style 4	Style 5	Style 9	Style 10	Style 11

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.

Rubber-Cushioned Abrasive Grinding Bits without Shank for Metals


Style 1	Style 2	Style 3	Style 4	Style 5

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.

Spiral-Wound Cartridge Sanding Rolls

Straight

Taper

Cone

As the outer layer wears away, new abrasive is exposed. A shank adapter or tapered spindle with a shank is required (both sold separately). The most common abrasive material, aluminum oxide is hard enough to sand steel and wood. The diameter listed is for the large end of the roll.

Straight—Straight rolls are for use in channels, fillets, recesses, contours, sidewalls, and other hard-to-reach spots.

Taper—Tapered rolls are for use on angles, corners, concave contours, funnel-shaped recesses, and other intricate shapes.

Cone—Cone rolls are for use in holes. Unlike tapered rolls, they have a flat surface to allow for a more even finish within internal surfaces.

Hook and Loop Sanding Discs for Stainless Steel and Hard Metals

Image of Product. Front orientation. Sanding Discs. Hook and Loop Sanding Discs for Stainless Steel and Hard Metals.

The extra-sharp abrasive cuts through hard metals faster than other discs. A hook-and-loop mount lets you switch grits and avoid the waste of adhesive-backed discs, which are done after one use. Pair with a compatible sanding tool or backup pad (sold separately).

Cloth Abrasive Backing—Resist tearing and hold up to wet sanding better than paper-backed discs.

Silicon Carbide Abrasive—Super sharp to cut quickly under light pressure. Silicon carbide is hard but brittle, so it tends to wear out sooner than other abrasives.

Grit—The lower the grit number, the rougher the finish and the duller the appearance. The higher the grit number, the more polished the finish and the more satin or mirrored the appearance.

Adhesive-Back Sanding Discs

Press these discs onto sanding tools or backup pads for a hold that won’t slip. To ensure the best bond, clean the pad with a mild alcohol—avoid harsh solvents such as MEK and acetone that can damage the adhesive. Also known as PSA discs.

Cloth Abrasive Backing—Resist tearing and hold up to wet sanding better than paper-backed discs.

Aluminum Oxide Abrasive—The most versatile and affordable abrasive we offer. Aluminum oxide is the go-to choice for general purpose sanding.

Grit—The lower the grit number, the rougher the finish and the duller the appearance. The higher the grit number, the more polished the finish and the more satin or mirrored the appearance.

Adhesive-Back Sanding Discs for Stainless Steel and Hard Metals

Image of Product. Front orientation. Sanding Discs. Adhesive-Back Sanding Discs for Stainless Steel and Hard Metals.

The abrasive on these discs is sharp and durable enough to cut hard metals without dulling quickly. Press discs onto sanding tools or backup pads for a hold that won’t slip. To ensure the best bond, clean the pad with a mild alcohol—avoid harsh solvents such as MEK and acetone that can damage the adhesive. Also known as PSA discs.

Cloth Abrasive Backing—Resist tearing and hold up to wet sanding better than paper-backed discs.

Silicon Carbide Abrasive—Super sharp to cut quickly under light pressure. Silicon carbide is hard but brittle, so it tends to wear out sooner than other abrasives.

Grit—The lower the grit number, the rougher the finish and the duller the appearance. The higher the grit number, the more polished the finish and the more satin or mirrored the appearance.
