Norton 662529-40095 Type 28 Saucer Grinding Wheel 7in

Product Description

The NORTON 662529-40095 is a Type 28 saucer-profile depressed-center grinding wheel engineered for metal grinding applications. Built with Gemini aluminum oxide abrasive, it delivers consistent cut rate and long wheel life on ferrous metals. The wheel measures 7 inches in diameter by 1/4 inch thick with a 7/8-inch arbor bore and is rated to a maximum of 8,600 RPM. It is sold individually and is a standard tool on job sites where fabricators, ironworkers, and metal finishing tradespeople need a reliable angle grinder wheel for surface grinding and weld blending work.

This wheel is suited for use on mild steel, structural steel, and similar ferrous metal stock in both shop and field environments. The Type 28 saucer geometry provides a lower grinding angle compared to flat Type 27 wheels, allowing better surface contact for blending, finishing, and cleaning flat workpieces. It is a common choice for weld prep, deburring, and surface conditioning tasks on fabricated steel assemblies and structural components.

Key Features

• Type 28 saucer profile for improved surface contact at low grinding angles
• Gemini aluminum oxide abrasive grain for consistent stock removal on ferrous metals
• 7 x 1/4 x 7/8 inch dimensions fit standard 7-inch angle grinders with 7/8-inch arbors
• 8,600 RPM maximum speed rating for safe operation on compatible grinders
• Depressed center design provides clearance for fasteners and weld beads

Compatibility

Designed for use on 7-inch angle grinders with a 7/8-inch arbor accepting Type 28 depressed-center saucer wheels rated at or below 8,600 RPM.

Installation Notes

Wheel mounting and replacement should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and unplug or lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting, and never exceed the rated maximum RPM marked on the wheel. Ensure the guard is properly installed before operation.
