Tru-maxx 66253255676 Surface Grinding Wheel 60 Grit

Product Description

The TRU-MAXX 66253255676 is a Type 1 surface grinding wheel engineered for precision stock removal and surface finishing on metalworking equipment. Built with aluminum oxide abrasive grain and a vitrified bond, this wheel delivers consistent cut rates and predictable wear characteristics across a broad range of ferrous metals. It measures 7 inches in diameter, 1/2 inch thick, and carries a 1-1/4 inch arbor hole. The 60 grit, J hardness rating makes it a strong choice for medium-material-removal work where surface finish quality still matters. Semi-friable grain structure supports self-sharpening action during use, extending effective wheel life.

This wheel is suited for surface grinders used in machine shops, tool rooms, and maintenance facilities handling ferrous stock. The vitrified bond performs well in both wet and dry grinding environments and tolerates the thermal cycling common in production surface grinding. The Type 1 straight-wheel profile fits standard horizontal-spindle surface grinder configurations. Licensed machinists, tool-and-die makers, and industrial maintenance technicians are the typical end users for this specification.

Key Features

• Aluminum oxide abrasive with semi-friable grain for consistent self-sharpening behavior
• Vitrified bond construction tolerates wet and dry grinding conditions
• 60 grit, J hardness (medium grade) balances material removal rate with surface finish quality
• Non-porous, non-recessed Type 1 straight-wheel profile fits horizontal-spindle surface grinders
• Grain structure rating of 6 provides a medium-open structure suitable for general ferrous grinding
• 3600 RPM maximum operating speed rated for standard surface grinder spindles

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for horizontal-spindle surface grinders accepting a 7 inch diameter, 1/2 inch thick, Type 1 wheel with a 1-1/4 inch arbor hole.

Installation Notes

Grinding wheel mounting and dressing must be performed by qualified personnel following ANSI B11.22 and applicable machine-specific guarding requirements. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use using the ring test — do not mount a damaged wheel. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
