Tru-maxx 66253292506 Surface Grinding Wheel 60 Grit

Product Description

The TRU-MAXX 66253292506 is a Type 1 straight surface grinding wheel designed for precision material removal on surface grinders. It is constructed from aluminum oxide abrasive bonded with a vitrified bond system, producing a pink wheel with a semi-friable grain structure rated at grain structure 6. The wheel operates at a maximum of 5410 RPM and carries a J hardness code, placing it in the medium hardness range. At 6 inches in diameter and 1/2 inch thick with a 1-1/4 inch arbor hole, this wheel fits standard surface grinder spindle configurations. It is installed and used by machinists, tool and die makers, and maintenance technicians in job shops and industrial facilities.

This wheel is suited for surface grinding operations on ferrous metals and tool steels where a medium-grade, 60-grit cut is appropriate. The 60-grit specification delivers a balance between stock removal rate and surface finish quality, making it a practical choice for general-purpose surface grinding and light tool reconditioning. The vitrified bond provides rigidity and open structure for efficient chip clearance during wet or dry grinding passes. The non-porous construction and semi-friable abrasive help the wheel maintain a consistent cutting edge throughout its service life.

Key Features

• Type 1 straight wheel profile fits standard surface grinder arbors
• 60-grit aluminum oxide abrasive for general-purpose ferrous metal grinding
• Vitrified bond with grain structure 6 for rigidity and chip clearance
• J hardness code (medium) balances wheel life and cutting action
• Semi-friable grain promotes self-sharpening during use
• Rated to 5410 RPM maximum operating speed

Compatibility

Designed as a standard Type 1 surface grinding wheel for use on horizontal-spindle surface grinders accepting a 1-1/4 inch arbor hole and wheels up to 6 inches in diameter.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Always power down and lock out the surface grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B7.1 standards. Never exceed the 5410 RPM maximum operating speed marked on the wheel.
