Grinding wheels are used for dressing the surface of material, from hard and soft metals, to stone and concrete, to plastics. The various product designs and abrasive types allow a great range of uses.
See "Abrasive Materials and Applications" tab below for specific types and purposes.
Abrasive Materials and Applications
ZA24T - Zirconia Aluminum Oxide give consistent grinding action for quicker and easier working. The zirconia grain is sharper, cuts faster, and lasts longer than aluminum oxide grain.
T-grade bond and 24 grain size.
WA24S - White Aluminum Oxide with an S-grade bond is a contaminant-free design for fast cutting of stainless steel, ferrous metals, food grade, and nuclear applications. Contains virtually no iron, sulfur, or chlorine for rust-free and corrosion free results.
A24R - Aluminum Oxide Grain is the #1 selling 1/4" Depressed Center grinding wheel. The R-grade bond provides for longer life and excellent stock removal.
A24N Fast Cut - Aluminum oxide grain and soft N-grade bond provides for fast stock removal. This is an economical choice for metal and low-grade stainless steel.
A30N - Premium Aluminum oxide grain, with a soft N-grade bond, designed for use on aluminum, copper, zinc, and other soft metals.
C24R Fast Cut - Silicon carbide grain and R-grade bond are designed for easy working on masonry, concrete, and stone.
C3 Ceramic - CGW'S new ceramic grinding disc is the best choice for grinding stainless steel, titanium, Inconel, and other hard metals. Using CGW’s ceramic grinding disc will give a "cool grinding surface" since the grain has a self sharpening formula.
Cotton - Yes, Cotton. Cotton Fiber impregnated with aluminum oxide grains and latex bond for superior stainless steel and aluminum blending and finishing. Grind and finish with one wheel. Aluminum will not load up.
