Tru-maxx 66253255218 Grinding Wheel 7in 120 Grit

Product Description

The TRU-MAXX 66253255218 is a Type 1 bench and pedestal grinding wheel designed for precision material removal and tool sharpening in shop and industrial settings. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action across ferrous metals and tool steels. The wheel measures 7 inches in diameter, 1 inch thick, with a 1-inch arbor hole and is rated for a maximum of 3600 RPM. At 120 grit with a fine grade and medium hardness rating, it suits finish grinding and light stock removal. Licensed machinists, toolroom technicians, and metal fabricators are the typical end users.

This wheel is suited for bench grinders and pedestal grinders used in toolrooms, maintenance shops, and fabrication facilities. Common applications include sharpening cutting tools, deburring ferrous workpieces, and surface cleanup on steel components. The semi-friable grain structure helps the wheel resist loading while maintaining a consistent cutting edge throughout the wheel life. The non-porous, vitrified bond construction provides rigidity and dimensional stability under sustained use.

Key Features

• 120 grit, fine grade for controlled finish grinding and light stock removal
• Aluminum oxide abrasive with vitrified bond for rigid, stable cutting action
• Semi-friable grain structure resists wheel loading during sustained grinding
• Rated to 3600 RPM maximum for standard bench and pedestal grinder spindle speeds
• Type 1 straight wheel profile for flat-face grinding applications
• Specification grade 27A120O6V13 for traceable quality reference

Compatibility

Designed as a direct-fit replacement for Type 1 straight grinding wheels on standard bench and pedestal grinders accepting a 1-inch arbor hole and a 7-inch diameter wheel. No bushing is included.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Disconnect and lock out power to the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test by tapping lightly with a non-metallic tool to confirm integrity. Never exceed the 3600 RPM maximum speed rating, and always replace wheel guards and flanges before returning the grinder to service.
