Emery
Emery is a dark gray, round shaped grain which tends to polish rather than abrade a work surface.

• For polishing and cleaning metal only.

Crocus
Iron Oxide (crocus) is a very soft, natural abrasive which is red in color.

• For fine polishing soft metals such as gold.

Silicon Carbide
Silicon carbide is the hardest and sharpest of the manufactured abrasives. Because of it's extreme sharpness, this bluish-black abrasive permits fast stock removal and cool cut.

• For use with: nonferrous metals, i.e., brass, aluminum, bronze,
• non-metallics, i.e., glass, rubber, plastic, stone,
• final finish on wood and stainless steel
• abrasive planing particleboard,
• Cast iron

Zirconia Alumina
Zirconia alumina is an ultra-tough, synthetic abrasive which provides a free, cool cut for high stock removal applications. It is tougher and sharper than aluminum oxide. It has a micro-crystalline structure which allows for controlled breakdown and self-sharpening.

• For heavy duty snagging and grinding all ferrous and nonferrous metals,
• abrasive planing of wood, plywood and particleboard,
• grinding fiberglass, rubber and plastics.

Light Brown aluminum oxide
Light brown aluminum oxide is a tough, yet sharp, synthetic abrasive characterized by cool cut, long life and the ability to break down under pressure producing new cutting edges.

• For production wood sanding,
• nonferrous metal finishing.

Brown aluminum oxide
Brown aluminum oxide is a tough, durable, synthetic abrasive characterized by the long life and wear resistance of it's cutting edges. It offers enormous penetrating strength, even at high speeds.

• For use with ferrous metals,
• hard wood.

Ceramic Alumina
The sub-micron structure of ceramic alumina allows each grain to continually expose sharp cutting points, resulting in a cooler cutting action and an extended life.

• For all ferrous/nonferrous metals, carbon steel and exotic alloys.
