Norton 66252917052 Type 29 Grinding Wheel 7in 36 Grit

Product Description

The NORTON 66252917052 is a Type 29 depressed center grinding wheel built for aggressive material removal on angle grinders. It measures 7 inches in diameter and 1/8 inch thick, with a 5/8-11 threaded arbor hole for secure mounting. The abrasive material is aluminum oxide at 36 grit, placing it in the very coarse grade range. This combination delivers fast stock removal on steel, iron, and similar ferrous materials. The resinoid bond holds the abrasive grains firmly during heavy grinding passes. Licensed tradespeople and fabricators working in metal fabrication, construction, or maintenance use this wheel for weld blending, surface preparation, and deburring tasks.

This wheel is designed for use with standard 7-inch angle grinders in both shop and field environments. Its Type 29 saucer-shaped profile allows the wheel to contact the workpiece at an angle, reducing chatter and improving control during edge work and flat surface grinding. The coarse 36 grit rating makes it best suited for initial material removal rather than finishing. It is sold individually and fits grinding applications across light industrial and heavy-duty field service settings.

Key Features

• Type 29 depressed center profile for low-angle grinding and improved surface contact
• Aluminum oxide abrasive at 36 grit for fast, aggressive material removal
• Resinoid bond construction for durability under sustained grinding loads
• 5/8-11 threaded connector for direct mounting to standard angle grinder spindles
• Rated to 8,600 RPM maximum for safe operation within grinder speed ratings
• 1/8 inch wheel thickness provides a balance of cutting aggression and wheel longevity

Compatibility

Designed for use with angle grinders equipped with a 5/8-11 threaded spindle. Confirm your grinder's no-load RPM does not exceed 8,600 RPM before installing this wheel.

Installation Notes

Installation should be performed by a qualified operator familiar with angle grinder safety procedures. Always power down and unplug or de-energize the grinder before mounting or removing wheels. Inspect the wheel for cracks or chips before each use and never operate above the rated maximum RPM. Appropriate personal protective equipment including a face shield, gloves, and hearing protection is required during grinding operations.
