Abrasive Material

Abrasive materials cut and smooth the workpiece. Abrasives perform differently based on the workpiece material and is also affected by the grade and bond.

Aluminum Oxide is a strong, sharp, and durable abrasive that withstands heat and high speeds.
Silicon Carbide is a sharp synthetic abrasive that breaks down quickly to maintain a sharp edge for fast cutting of nonmetallic and low-tensile strength metals.
Ceramic self-sharpens to speed cutting which keeps the surface cooler, making it a good choice for heat-sensitive metals.

Abrasive Grade

Abrasive grade refers to the size and roughness of the abrasive material and affects material removal rates and finish quality. Tool choice, workpiece material, abrasive bond, and abrasive hardness also affect final results.

Coarser grits remove material at higher rates but leave a rougher finish than finer grades. They're often a better choice for soft, ductile, or stringy materials, such as aluminum and soft steel.

Finer grits remove less material and are used when a smooth surface is important and for applications that require precision finishing and close tolerances. Finer grits are a good choice when working with hard and brittle materials such as glass, tool steel, and cemented carbide.

Coarse is 30 to 50 grit.
Medium is 60 to 80 grit.
Fine is 100 to 120 grit.
Very Fine is 150 grit and higher.

Grit

Grit describes how the size of the abrasive grains. Coarser grits have larger grains with more space between the cutting edges to break down more quickly to maintain a sharp edge and remove material quickly. Finer grits have a smoother surface that remove less material and produce a smoother finish.

Specification

Wheel specification is a Norton-specific code that identifies wheel composition by abrasive, grit, wheel hardness grade, structure (grain spacing), and bond type. This code, printed on all Norton conventional grinding wheels, can be used to quickly identify replacement wheels.
