Tru-maxx 66253255427 Surface Grinding Wheel 8in 60 Grit

Product Description

The TRU-MAXX 66253255427 is a Type 1 straight surface grinding wheel designed for precision stock removal and surface finishing on ferrous metals and similar workpiece materials. It is manufactured from aluminum oxide abrasive grain bonded with a vitrified bond, producing a rigid, dimensionally stable wheel. At 60 grit with a K hardness rating and medium grade, this wheel balances cutting speed with surface finish quality. It is rated to a maximum of 3600 RPM. The semi-friable grain structure allows the wheel to self-sharpen during use, maintaining consistent cut rates over the wheel's service life. Licensed grinding machine operators and tool room machinists are the primary users of this wheel.

This wheel is suited for surface grinding operations on horizontal and reciprocating spindle grinders. The 8 inch diameter, 1/4 inch thickness, and 1-1/4 inch arbor hole fit standard production and tool room surface grinders configured for Type 1 straight wheels. It is appropriate for light to medium material removal passes on hardened steel, tool steel, and similar ferrous workpieces where a consistent 60-grit scratch pattern is acceptable. The non-porous, vitrified bond construction makes it suitable for use with water-soluble or oil-based grinding coolants.

Compatibility

Designed as an OEM-style replacement or direct-use Type 1 straight grinding wheel for surface grinders with a 1-1/4 inch arbor bore and a maximum wheel diameter capacity of 8 inches or greater.

Installation Notes

A qualified machine operator or tool room technician should mount and dress this wheel. Always power down and lockout the grinding machine before mounting or removing any wheel. Inspect the wheel for cracks or chips before mounting using the ring test — a damaged wheel must not be used. Never exceed the 3600 RPM maximum rated speed, and verify the machine spindle speed before operation.
