Tru-maxx 66253246705 Surface Grinding Wheel 7in 60 Grit

Product Description

The TRU-MAXX 66253246705 is a Type 5 recessed surface grinding wheel designed for precision stock removal and surface finishing on hard materials. Built with a silicon carbide abrasive grain and a vitrified bond, this wheel delivers consistent cut rate and maintains its form throughout the grinding cycle. The I hardness rating and 60 grit classification place it in the medium-grade range, making it well suited for controlled material removal without excessive loading. Rated to a maximum of 3600 RPM, it is sized at 7 inches in diameter and 1 inch thick, with a 1-1/4 inch arbor hole and a 3-inch one-side recess. The green wheel color is standard for silicon carbide wheels used in toolroom and surface grinding applications.

This wheel is intended for use on surface grinders in toolroom, maintenance, and production environments. The Type 5 recessed profile fits machines configured for recessed-hub mounting. Silicon carbide abrasive is particularly effective on non-ferrous metals, cast iron, carbide tooling, ceramics, and other hard or brittle materials. The vitrified bond provides rigidity and good chip clearance, which supports clean, accurate surface finishes. This is a non-porous wheel, appropriate for dry or compatible wet grinding setups depending on machine and material requirements.

Key Features

• Type 5 one-side recessed design with 3-inch recess diameter for compatible spindle mounting
• Silicon carbide abrasive grain — effective on carbide, cast iron, ceramics, and non-ferrous metals
• Vitrified bond provides form stability and open structure for efficient material removal
• 60 grit, I hardness (medium grade) for balanced stock removal and surface finish
• Rated to 3600 RPM maximum operating speed
• Non-porous construction supports consistent performance throughout wheel life

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for surface grinders accepting a Type 5 wheel with a 7-inch diameter, 1-inch face width, and 1-1/4 inch arbor hole.

Installation Notes

Surface grinding wheels must be installed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always perform a ring test before mounting and inspect the wheel for cracks or chips. Power down and lock out the grinder before mounting or removing the wheel, and verify the machine spindle speed does not exceed the wheel maximum RPM rating of 3600. Use the correct flanges and blotters as specified by the grinder manufacturer.
