Internal Diameter Toolroom Grinding Wheels for Metals


Recessed Grinding Wheel

Typically used with cylindrical, surface, and ID grinders, these wheels are specially designed to grind the inside diameter of workpieces. They’re often used to make bearings.

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

The special shapes of these wheels provide more clearance than typical straight wheels.

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

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

Heavy-Removal Norton Toolroom Grinding Wheels for Metals


Recessed 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.
