Norton 662530-49081 Type 28 Grinding Wheel 9x1/4x7/8 6600 Rpm

Product Description

The NORTON 662530-49081 is a Type 28 saucer-style depressed center grinding wheel engineered for metal grinding applications. Built with Gemini aluminum oxide abrasive, it delivers consistent stock removal and long wheel life on ferrous metals and general fabrication work. The wheel measures 9 inches in diameter by 1/4 inch thickness with a 7/8-inch arbor bore, and is rated to a maximum of 6600 RPM. It is intended for use with large angle grinders by metalworkers, fabricators, and maintenance trades requiring aggressive surface and weld grinding.

This wheel is suited for heavy-duty metal grinding tasks in fabrication shops, structural steel work, and industrial maintenance environments. The Type 28 saucer profile provides a lower grinding angle compared to flat Type 27 wheels, which reduces gouging and improves surface contact on flat and curved workpieces. The Gemini aluminum oxide grain is a proven abrasive for carbon steel, stainless steel, and similar metals requiring controlled, efficient material removal.

Key Features

• Type 28 saucer profile for low-angle grinding and improved surface contact
• Gemini aluminum oxide abrasive for consistent cut rate on ferrous metals
• 9-inch diameter by 1/4-inch thickness for aggressive stock removal
• 7/8-inch arbor bore fits standard large angle grinders
• Maximum rated speed of 6600 RPM
• Depressed center design keeps the flange clear of the workpiece

Compatibility

Designed for use on large angle grinders accepting a 9-inch depressed center grinding wheel with a 7/8-inch arbor bore. Suited for metal grinding applications on carbon steel, structural steel, and similar ferrous materials.

Installation Notes

Grinding wheel installation and operation should be performed by qualified personnel familiar with abrasive wheel safety standards, including ANSI B7.1 guidelines. Always inspect the wheel for cracks or damage before mounting and confirm the grinder's rated RPM meets or exceeds the wheel's 6600 RPM maximum speed rating. Power down and disconnect the grinder before mounting or removing the wheel. Always use the appropriate guard and personal protective equipment during operation.
