Norton 66252912633 Type 27 Grinding Wheel 7 in

Product Description

The NORTON 66252912633 is a Type 27 depressed center grinding wheel designed for use with angle grinders in heavy-duty material removal applications. Built with aluminum oxide abrasive and a resinoid bond, this 7-inch wheel delivers consistent cutting action on ferrous metals, welds, and rough surfaces. The threaded 5/8-11 hub mounts directly to standard angle grinder spindles. At 1/4 inch thick, it is suited for aggressive stock removal rather than cutting or finishing. Rated to 8,600 RPM, the wheel meets demands of professional fabrication, ironwork, and general grinding tasks on the job site or in the shop.

This wheel is used in metalworking, fabrication, construction, and maintenance applications where fast material removal is required. The Type 27 raised-hub profile keeps the grinding surface at a low angle to the workpiece, reducing user fatigue and improving control during extended use. Welders, pipefitters, ironworkers, and general contractors rely on this wheel size for weld blending, surface prep, and deburring on structural steel, pipe, and plate. The 7-inch diameter provides a wide grinding path, making it efficient on broad flat surfaces and larger welds.

Key Features

• Aluminum oxide abrasive for consistent stock removal on ferrous metals
• Resinoid bond provides durability and resistance to shock loading during grinding
• Type 27 raised-hub geometry keeps wheel face at a low working angle
• Threaded 5/8-11 hole for direct mount to standard angle grinder spindles
• 8,600 RPM maximum rating for compatibility with common 7-inch angle grinders
• 1/4 inch wheel thickness optimized for aggressive material removal

Compatibility

Designed for use with angle grinders accepting a 5/8-11 threaded spindle and a 7-inch grinding wheel. Suitable for standard angle grinders commonly used in fabrication and construction trades.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Disconnect and de-energize the angle grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never operate above the rated 8,600 RPM. ANSI B7.1 and applicable OSHA standards govern the safe use, handling, and guarding of abrasive wheels in the workplace.
