Norton General Purpose Toolroom Grinding Wheels for Metals

Use these wheels for precision grinding on surface, cylindrical, and tool and cutter grinders. They are also known as Type 1 wheels and straight wheels.

Truing and cleaning before first use is recommended.

Norton 38A Abrasive—38A white wheels are for light material removal. They stay cool during use, so they're a good choice for heat-sensitive applications. They are aluminum oxide, which is the most common abrasive used in grinding metal.

Norton 32A Abrasive—32A purple wheels are for medium to heavy material removal. They are aluminum oxide.

Norton Long-Life Toolroom Grinding Wheels for Metals

A more durable abrasive allows these wheels to remove more material and last longer than Norton General Purpose Grinding Wheels. They are also known as Type 1 wheels and straight wheels.

Truing and cleaning before first use is recommended.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Norton 32AA Abrasive—32AA purple wheels are for medium to heavy material removal. They are a blend of aluminum oxide and ceramic alumina, which lasts up to twice as long as Norton 32A General Purpose Grinding Wheels.

Norton 5SG Abrasive—5SG blue wheels are for heavy material removal. They are ceramic aluminum oxide, which lasts up to five times as long as Norton 32A General Purpose Grinding Wheels.

Heavy-Removal Norton Toolroom Grinding Wheels for Metals


Recessed Grinding Wheel	Straight Grinding Wheel

Plated-Disc Grinding Wheel

The porous bond leaves more space between abrasive grains so heavy amounts of chips and coolant easily flow through.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Norton 32A Abrasive—32A purple wheels are for medium to heavy material removal. They are aluminum oxide, which is the most common abrasive used in grinding metal.

Norton 5SG Abrasive—5SG blue wheels are for heavy material removal. They are ceramic aluminum oxide, which lasts up to five times as long as 32A wheels.

Norton Toolroom Grinding Wheels for Soft Metals


Cylindrical Grinding Wheel	Straight Grinding Wheel

Unlike aluminum oxide wheels, these silicon carbide wheels won't clog when grinding soft metals.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Grinding Wheel Segments for Surface Grinders

Grind flat stock and flat surfaces with these segments. You can use several together in your surface grinder's chuck so they move over your workpiece, or keep the segments stationary and move your workpiece.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Mounted Dressers for Toolroom Grinding Wheels

Dressers have a diamond abrasive, which is extremely hard and wear resistant. They mount onto surface, cylindrical, and tool and cutter grinding equipment. They are also known as cleaners.

Single Point


Round Shank with Round Head—For Use With Norton Machines	Round Shank with Round Head—For Use With Cincinnati Machines

A single point removes more material than dressers with multiple points.

Not Resettable—Nonresettable dressers have one point.

Centerless Grinding Wheels

Remove material and shape metal cylindrical forms or parts without the need for centers or fixtures. These wheels have tight dimensional tolerances and create a smooth surface. They’re good for grinding numerous materials with just a few machines.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
