Tru-maxx 66253269895 Surface Grinding Wheel 60 Grit 8in

Product Description

The TRU-MAXX 66253269895 is a Type 1 surface grinding wheel designed for precision stock removal and surface finishing on ferrous and non-ferrous metals. The abrasive matrix is aluminum oxide bonded with a vitrified bond, yielding consistent cut rates and predictable wear. At 60 grit with a medium grade and I hardness code, this wheel balances aggressive material removal with adequate wheel life. It is rated to a maximum of 3600 RPM. Machinists and tool room operators use this wheel in surface grinders where flat, parallel finishes are required on workpiece faces.

This wheel fits standard surface grinder spindles configured for a 1-1/4 inch arbor bore. The 8 inch diameter and 1/2 inch face width suit horizontal-spindle reciprocating table surface grinders commonly found in job shops, maintenance facilities, and production machine shops. The ruby-colored, non-porous aluminum oxide structure is well suited to grinding hardened tool steels, carbon steels, and similar ferrous materials where heat control and consistent finish are priorities.

Key Features

• Aluminum oxide abrasive grain for grinding hardened ferrous materials
• Vitrified bond provides consistent wheel structure and coolant compatibility
• 60 grit medium grade for balanced material removal and surface finish
• I hardness code suits general-purpose surface grinding applications
• Type 1 straight wheel profile with no recess and no taper
• Non-porous ruby wheel body rated to 3600 RPM maximum operating speed

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for horizontal-spindle surface grinders accepting an 8 inch diameter, 1/2 inch thick, Type 1 straight wheel with a 1-1/4 inch arbor bore.

Installation Notes

Grinding wheel installation and dressing must be performed by qualified machinists following ANSI B11.9 and applicable shop safety standards. Before mounting, ring-test the wheel for cracks and verify the grinder spindle speed does not exceed the 3600 RPM maximum marked on the wheel. Never exceed the rated spindle speed. Use proper flanges and a compressible blotter between the flange and wheel face; do not over-torque the arbor nut. After mounting, run the wheel in a guarded position for at least one minute before bringing it near the workpiece.
