Tru-maxx 66253255610 Surface Grinding Wheel 8in 60 Grit

Product Description

The TRU-MAXX 66253255610 is a Type 1 straight surface grinding wheel designed for precision stock removal and surface finishing on ferrous and non-ferrous materials. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and good form retention throughout its service life. At 8 inches in diameter, 1/2 inch thick, and with a 1-1/4 inch arbor hole, it mounts directly to standard surface grinder spindles. The 60 grit, medium grade specification suits general-purpose material removal where a balance of cut rate and surface finish is required. Maximum rated speed is 3600 RPM. This wheel is intended for use by machinists, toolroom operators, and grinding specialists working on surface grinders in production or maintenance environments.

This wheel fits horizontal-spindle reciprocating surface grinders commonly found in machine shops, tool and die operations, and maintenance repair facilities. The aluminum oxide abrasive is well suited for grinding steel, ferrous alloys, and similar hard materials. The vitrified bond provides a rigid structure that holds grit position under moderate grinding pressure, making it appropriate for flat surface work, step grinding, and light form grinding applications where dimensional accuracy matters.

Key Features

• Aluminum oxide abrasive with semi-friable grain structure for consistent, controlled cutting
• Vitrified bond provides rigid grit retention and good form stability
• 60 grit medium grade balances material removal rate with surface finish quality
• Hardness Code I (soft-to-medium range) promotes self-dressing action to reduce glazing
• Non-porous, non-tapered Type 1 straight wheel profile for flat surface grinding
• 3600 RPM maximum rated speed for safe operation on standard surface grinder spindles

Compatibility

Designed as a standard Type 1 straight replacement grinding wheel for horizontal-spindle surface grinders accepting an 8 inch diameter, 1/2 inch wide wheel with a 1-1/4 inch arbor bore.

Installation Notes

Surface grinding wheels must be installed by qualified machinists or grinding equipment operators familiar with ANSI B11.22 safety standards for surface grinding machines. Before mounting, power down and lock out the grinder, inspect the wheel for cracks or chips by performing a ring test, and verify the spindle speed does not exceed the 3600 RPM wheel rating. Use proper flange hardware and do not overtighten the arbor nut; always run the wheel in a guarded position for at least one minute before bringing it into contact with the workpiece.
