Brown Aluminum Oxide Grinding Wheels

A

Dark Brown

High toughness, High bearing force, Strong anti-crushing ability. Used in anti-metal, such as rough grinding for carbon steel, alloy steel, malleable cast iron, hard bronze and etc.

White Aluminum Oxide Grinding Wheels

WA

White

Lower toughness, the fragile grains, sharp edge, the ability of its grinding is superior to A. Used in grinding hardened steel, alloy steel, high speed steel, High carbon steel as well as thin wall workpiece, Generally grinding thread, gear, blade, inside and out side diameter, surface and etc.

Chromium Corundum Grinding Wheels

PA

Pink

Toughness is lower than WA, good surface finish, high efficiency. Used in grinding cutter, measuring tool, meter thread as well as workpiece needed high surface finishing.

Single Crystal Corundum Grinding Wheels

SA

Buff or White
