Norton 66252843229 Type 28 Grinding Wheel 7in 24 Grit

Product Description

The NORTON 66252843229 is a Type 28 depressed center grinding wheel designed for aggressive material removal with an angle grinder. Built with a zirconia alumina abrasive grain and a coarse 24 grit rating, this wheel cuts fast on tough metals including stainless steel, structural steel, and cast iron. The resinoid bond holds grain securely under heavy load, and the hardness code S designation indicates a firm wheel suited for high-pressure grinding applications. At 7 inches in diameter and 1/4 inch thick, it fits standard large-angle grinders and is rated to a maximum of 8,600 RPM. Installers and fabricators in industrial, construction, and maintenance trades are the primary users.

This wheel is used for weld grinding, surface blending, and stock removal on ferrous metals in fabrication shops, construction sites, and maintenance facilities. The Type 28 saucer profile allows for a lower grinding angle, reducing operator fatigue during extended flat-surface grinding. It threads directly onto the grinder spindle via a standard 5/8-11 threaded hub, which is the most common arbor size on 7-inch angle grinders. Both professional fabricators and maintenance technicians will find this wheel appropriate for heavy-duty, high-stock-removal tasks.

Key Features

• Zirconia alumina abrasive grain for fast cut rate on ferrous metals
• 24 grit coarse grade for aggressive stock removal and weld grinding
• Type 28 depressed center profile reduces grinding angle for flat surface work
• Resinoid bond with hardness code S for durability under heavy grinding pressure
• 5/8-11 threaded hub fits standard angle grinder spindles directly
• 8,600 RPM maximum speed rating for use with 7-inch angle grinders

Compatibility

Designed for use with angle grinders accepting a 7-inch, 5/8-11 threaded depressed center wheel.

Installation Notes

Mounting and removal of grinding wheels should be performed by qualified personnel following ANSI B7.1 safety standards. Always power down and disconnect the grinder from its power source before changing wheels. Inspect the wheel for cracks or chips before installation, and never exceed the marked maximum RPM. Use the correct guard configuration for the wheel type as required by the grinder manufacturer and applicable OSHA regulations.
