CGW 45082 9" X 1/4" X 5/8"-11 WA24-R Type 27 24-Grit White Aluminum Oxide Grinding Wheel

The CGW 45082 grinding wheel is a 9-inch, silver aluminum oxide wheel designed for fast cutting of stainless steel and ferrous metals. Its WA24-R Type 27 profile provides a depressed-center configuration suitable for angular grinding, enabling efficient material removal on flat or contoured surfaces. The wheel features a 1/4-inch thickness and a 5/8-11 mounting arbor, with a 24-grit, white aluminum oxide grain that emphasizes cut-rate consistency across workpieces. A contaminant-free formulation—containing less than 0.01% iron, sulfur, or chlorine—helps minimize rust or corrosion on treated parts and equipment, which can be advantageous when working with metal assemblies sensitive to contamination.

Construction and distinguishing features include a Type 27 configuration designed for off-angle grinding and a hardened grain structure that supports sustained cutting performance at up to 6,600 RPM. The wheel’s white aluminum oxide abrasive is selected for its balance of durability and metal-cutting capability, contributing to predictable wear and finished edge quality on ferrous materials. These attributes matter when selecting tooling for deburring, shaping, or blending welds on stainless steel and other metals, where surface integrity and consistent cut quality are important.

Practical considerations include matching to compatible angle grinders with a 5/8-11 arbor and ensuring proper guard clearance for depressed-center wheels. The package indicates a per-item unit size with 10 wheels per box, which can affect downtime planning and inventory. When mounting, verify the grinder’s speed rating does not exceed the wheel’s maximum RPM (6600) to maintain safe operation and consistent performance. Cross-check application needs with the wheel’s grit and profile to determine suitability for metered material removal, edge work, or contour grinding on metal components.
