Norton 662529-39259 Type 27 Grinding Wheel 7in Aluminum Oxide

Product Description

The NORTON 662529-39259 is a Type 27 depressed-center grinding wheel engineered for metal grinding and stock removal applications. Built with Gemini aluminum oxide abrasive, this wheel delivers consistent cut rate and durability across a wide range of ferrous metals. At 7 inches in diameter with a 0.125-inch thickness and a 5/8-11 threaded arbor, it mounts directly to standard angle grinders and fits the most common spindle thread used in the trade. The wheel is rated to a maximum of 8,600 RPM, making it compatible with most 7-inch grinder models operating within that speed range.

This wheel is suited for use in metal fabrication, structural steel work, weld blending, and general surface grinding on ferrous materials. The Type 27 depressed-center profile allows the wheel face to contact the workpiece at a low angle, giving the operator better control and access in flat and confined grinding scenarios. It is appropriate for both shop and field use by welders, pipefitters, ironworkers, and general metal tradespeople.

Key Features

• Gemini aluminum oxide abrasive grain for consistent metal stock removal
• Type 27 depressed-center design allows low-angle grinding access
• 7 inch diameter x 0.125 inch thickness for aggressive yet controlled grinding
• 5/8-11 threaded arbor fits standard angle grinder spindles
• 8,600 RPM maximum speed rating for compatibility with common 7-inch grinders

Compatibility

Designed for use with 7-inch angle grinders equipped with a 5/8-11 spindle thread and a speed rating at or below 8,600 RPM. Intended for grinding ferrous metals.

Installation Notes

This wheel must be mounted by a qualified operator following the angle grinder manufacturer's instructions and ANSI B7.1 safety requirements for abrasive wheels. Always confirm the grinder's no-load RPM does not exceed the wheel's 8,600 RPM maximum before mounting. Inspect the wheel for cracks or damage before each use and never use a wheel that has been dropped or shows visible defects. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation.
