Bullard 28466 Grinding Wheel 4.5in Type 27 C24R 13300 Rpm

Product Description

The BULLARD 28466 is a Type 27 depressed center grinding wheel designed for angle grinder applications in metal fabrication, welding prep, and surface grinding work. Measuring 4.5 inches in diameter with a 0.25-inch thickness and a 5/8-11 arbor, this wheel mounts directly to standard angle grinders without adapters. The C24R specification indicates a coarse 24-grit silicon carbide bond suited for aggressive stock removal on masonry, concrete, and non-ferrous materials. Rated to a maximum of 13,300 RPM, it is built to match the output of common 4.5-inch angle grinders used by tradespeople in fabrication and construction environments.

This wheel is intended for use with 4.5-inch Type 27-compatible angle grinders in both residential construction and commercial job site applications. Typical install scenarios include weld bead grinding, surface preparation before coating, and rough shaping of concrete or masonry surfaces. The 5/8-11 threaded arbor is the standard mount found on most full-size 4.5-inch angle grinders. Sold individually, with a box quantity of 10 units, making it practical to stock for ongoing production or crew supply.
