Tru-maxx 66253269724 Surface Grinding Wheel 100 Grit

Product Description

The TRU-MAXX 66253269724 is a Type 1 surface grinding wheel designed for precision material removal on surface grinders. It measures 7 inches in diameter, 1/4 inch thick, with a 1-1/4 inch arbor hole. The wheel is manufactured from ceramic abrasive grain bonded with a vitrified bond system, rated at K hardness with a grain structure of 6 and a grit of 100 (fine grade). The vitrified bond provides rigidity and porosity control, making it well suited to consistent stock removal and fine surface finishing. Rated to a maximum of 3600 RPM.

This wheel is intended for surface grinding applications in machine shops, toolrooms, and maintenance environments. It is a flat, straight-profile Type 1 wheel with no recess, compatible with horizontal-spindle reciprocating-table surface grinders. The 100-grit fine grade targets finish grinding passes where dimensional accuracy and surface finish quality matter. The blue color identifies the ceramic grain composition. It is appropriate for grinding ferrous and hardened materials where ceramic abrasive offers longer wheel life and cooler cutting compared to conventional aluminum oxide.

Key Features

• Type 1 straight wheel profile with no recess — mounts directly on standard surface grinder arbors
• Ceramic abrasive grain for cooler cut and extended wheel life on hardened steels
• Vitrified bond provides structural rigidity and consistent grit exposure throughout wheel life
• 100 grit (fine grade) suited for finish grinding and tight-tolerance surface work
• K hardness (medium) balances wheel longevity with free-cutting action
• Maximum operating speed of 3600 RPM

Compatibility

Designed as a direct-mount replacement or consumable wheel for horizontal-spindle surface grinders accepting a 7-inch diameter, 1/4-inch wide Type 1 wheel with a 1-1/4-inch arbor hole.

Installation Notes

Installation should be performed by a qualified machine operator or toolroom technician following ANSI B7.1 safe-use standards for abrasive wheels. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI guidelines. Never exceed the rated maximum speed of 3600 RPM; confirm the machine spindle speed before operation.
