Norton 66252849370 Type 27 Grinding Wheel 5 Inches

Product Description

The NORTON 66252849370 is a Type 27 depressed center grinding wheel designed for material removal on aluminum and similar non-ferrous surfaces. Built with an aluminum oxide abrasive and a resinoid bond, this 5-inch wheel delivers consistent cut rate and durability under sustained grinding loads. The reinforced construction supports safe operation up to 12,225 RPM, making it suitable for use with standard 5-inch angle grinders. The 7/8-inch arbor hole fits the most common spindle size found on portable grinders used in fabrication, maintenance, and field service work. HVAC technicians, pipefitters, and general metal tradespeople will find this wheel a reliable go-to for deburring, weld blending, and surface prep on aluminum workpieces.

This wheel is intended for grinding aluminum in light fabrication, HVAC ductwork prep, and general metalworking applications. The Type 27 depressed center profile keeps the grinding face angled slightly off the workpiece surface, reducing gouging risk and improving control on flat stock, tubing, and sheet metal. It is sold individually and fits 5-inch right-angle grinders with a standard 7/8-inch arbor. The black resinoid-bonded wheel is well-suited for shop bench use as well as jobsite conditions.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Always confirm the grinder's rated RPM meets or exceeds the wheel's 12,225 RPM maximum before mounting. Power down and disconnect the grinder from its power source before changing wheels, and verify the arbor flange and backing flange are clean and undamaged. Inspect the wheel for cracks or chips before each use and never operate a damaged abrasive wheel.
