CGW 36109 5" X 1/4" X 7/8" A30-N Type 27 30-Grit Calcium Stearate Grinding Wheel for Aluminum

The CGW 36109 is a small-diameter grinding wheel designed for non-ferrous metals, notably aluminum, copper, and zinc. It is a 5 inch wheel with a 1/4 inch thickness and a 7/8 inch arbor size, configured as a Type 27 non-woven cup-style wheel intended for flat-to-convex grinding tasks. The wheel uses a 30-grit aluminum oxide grain set in a soft N-grade bond, engineered to deliver a non-loading cutting action that helps maintain material removal efficiency when working on delicate or soft metals.

The combination of aluminum oxide grit and a calcium stearate formulation contributes to reduced loading and smoother grinding, which can be important when removing welds or smoothing surfaces on non-ferrous joints. The A30-N specification indicates a balance between aggressiveness and control, suitable for weld removal and finishing operations where heat generation and gouging must be minimized. These wheels are commonly used on tasks such as deburring, beveling, or contour grinding on aluminum and other non-ferrous components.

When selecting this wheel, ensure compatibility with your tool’s arbor and RPM rating. This particular wheel is specified at 12,200 RPM, and with a 5" diameter, 1/4" thickness, and 7/8" arbor, it is important to verify your grinder’s speed capability and mounting fit before operation. Packaged individually but available in box quantities, this CGW wheel is appropriate for maintenance, fabrication, and shop floor use where controlled removal of welds or surface finishing on aluminum and similar metals is required.
