Tru-maxx 66253255575 Surface Grinding Wheel 60 Grit

Product Description

The TRU-MAXX 66253255575 is a Type 1 surface grinding wheel designed for precision stock removal and surface finishing on ferrous and non-ferrous workpieces. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and long service life in surface grinding applications. It measures 7 inches in diameter, 3/4 inches thick, and carries a 1-1/4 inch arbor hole. The 60 grit, medium grade, I hardness rating makes it well suited for general-purpose material removal where surface finish and dimensional control are both priorities. Maximum operating speed is 3600 RPM.

This wheel is intended for use on horizontal spindle surface grinders in tool rooms, maintenance shops, and production grinding environments. It is appropriate for grinding carbon steel, alloy steel, and similar hard materials. The vitrified bond provides rigidity and porosity control, supporting consistent performance across both light and moderate cuts. Machinists, tool and die workers, and maintenance technicians working with surface grinders in the 7-inch wheel class will find this a direct-fit option for standard arbor configurations.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous metals
• Vitrified bond construction provides dimensional stability and consistent cut rate
• 60 grit, medium grade for general-purpose stock removal and surface finishing
• I hardness rating with semi-friable grain structure for balanced wear and sharpness
• Non-porous, no-recess Type 1 wheel profile for straightforward mounting
• Rated to 3600 RPM maximum operating speed

Compatibility

Designed as an OEM-style replacement or standard consumable for horizontal spindle surface grinders accepting a 7-inch diameter, 1-1/4 inch arbor hole, Type 1 straight wheel.

Installation Notes

Surface grinding wheels must be installed by qualified machinists or maintenance technicians following all applicable machine guarding and abrasive wheel safety requirements, including ANSI B11.24 and OSHA 29 CFR 1910.215. Before mounting, visually inspect the wheel for cracks and perform a ring test. Never exceed the wheel's maximum rated RPM of 3600. Ensure the spindle and flanges are clean and that the arbor hole fit is correct before tightening.
