Norton 66252843234 Type 27 7 Inch Grinding Wheel 30 Grit

Product Description

The NORTON 66252843234 is a Type 27 depressed center grinding wheel designed for aggressive material removal on angle grinders. Built with a zirconia alumina abrasive grain and a coarse 30-grit rating, this wheel cuts fast and holds up under sustained grinding pressure on steel and other ferrous metals. The resinoid bond matrix holds the grain firmly throughout the wheel life, and the hardness code U construction resists loading on heavy stock removal tasks. At 7 inches in diameter and 0.125 inches thick, it fits standard 7-inch angle grinders and weighs approximately 0.51 pounds.

This wheel is suited for surface grinding, weld blending, and edge work on fabrication projects in metal shops, construction sites, and industrial maintenance environments. The 7/8-inch arbor hole mounts directly to angle grinder spindles via a standard arbor connector. Coarse 30-grit zirconia alumina is the right choice when the job calls for rapid stock removal rather than fine finishing. Licensed metalworkers, fabricators, pipefitters, and ironworkers are the primary users of this wheel in professional trade settings.

Key Features

• Type 27 depressed center profile for flat and edge grinding clearance
• Zirconia alumina grain for fast, cool-cutting performance on ferrous metals
• Coarse 30 grit rated for aggressive stock removal and weld grinding
• Resinoid bond with hardness code U for durability under load
• 8,600 RPM maximum rated speed for 7-inch angle grinder compatibility
• Lightweight at 0.51 pounds for reduced user fatigue on extended tasks

Compatibility

Designed for use with 7-inch angle grinders fitted with a 7/8-inch arbor spindle. Confirm your grinder's spindle speed rating meets or falls below 8,600 RPM before mounting.

Installation Notes

Installation must be performed by a qualified operator following the grinder and wheel manufacturer safety guidelines. Inspect the wheel for cracks or chips before mounting and never use a damaged wheel. Always ensure the grinder is unplugged or the power source is isolated before changing wheels, and verify the spindle RPM rating does not exceed the 8,600 RPM maximum stamped on the wheel. Wear appropriate PPE including a face shield, gloves, and hearing protection during grinding operations.
