CGW 45003 4-1/2" X .045" X 7/8" Type 27 60-Grit White Aluminum Oxide Cutting Wheel

The CGW 45003 is a Type 27 grinding wheel designed for rapid material removal on non-ferrous metals and other soft alloys. Its 4-1/2 in diameter, 0.045 in thick wheel features a 7/8 in arbor hole, making it compatible with common angle grinders and cutoff/rotary tools used in facility maintenance and fabrication tasks. The wheel is manufactured with white aluminum oxide abrasive, selected for its clean-cutting action and consistent performance in light to moderate-duty grinding applications.

Key construction details include a friable grain structure that is intended to promote efficient cutting with a lower tendency to heat the workpiece. The wheel is formulated to minimize contamination, boasting low levels of iron, sulfur, and chlorine, which helps reduce rust and corrosion on sensitive materials and tool surfaces. This makes it suitable for applications where surface integrity and cleanliness are important after machining.

Typical use scenarios include deburring, edge blending, and material finishing on metals where a relatively fine grade is appropriate. The 60-grit specification supports a balance between material removal rate and surface finish quality. When selecting accessories and wheels, ensure proper mounting and guard clearance for a 4.5-inch Type 27 wheel and verify RPM compatibility with your grinder, as operating at or below the wheel’s maximum 13,300 RPM helps maintain wheel integrity and user safety. The package contains individual wheels, with a box quantity of 25, which supports stocked replacement needs for small shops or maintenance teams.
