Tru-maxx 66253255863 Surface Grinding Wheel 60 Grit 7in

Product Description

The TRU-MAXX 66253255863 is a Type 1 straight surface grinding wheel designed for precision stock removal and surface finishing on ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and thermal stability during dry or wet grinding operations. It measures 7 inches in diameter, 1/4 inch thick, with a 1-1/4 inch arbor hole, and is rated to 3600 RPM. The 60 grit, medium grade, I hardness specification makes it well suited for moderate material removal where surface finish and wheel life need to be balanced. This wheel is white in color and semi-friable, meaning it self-sharpens during use to maintain cutting efficiency.

This grinding wheel is used in surface grinding applications on pedestal grinders, bench grinders, and surface grinding machines in machine shops, maintenance facilities, and fabrication environments. The Type 1 straight profile fits standard surface grinder spindles and is appropriate for grinding carbon steel, tool steel, and similar ferrous workpieces. Licensed machinists, tool and die makers, and maintenance technicians are the typical users. The non-porous, vitrified bond construction provides rigidity and resistance to oils and coolants commonly encountered in shop environments.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous metals
• Vitrified bond for rigidity, heat resistance, and coolant compatibility
• 60 grit medium grade for balanced material removal and surface finish
• Semi-friable grain construction promotes self-sharpening during use
• Type 1 straight wheel profile fits standard surface grinder arbors
• Non-porous construction resists loading on steel workpieces

Compatibility

Designed as an OEM-style replacement or standard fitment for Type 1 surface grinding wheel applications requiring a 7 inch diameter, 1-1/4 inch arbor hole, and a maximum spindle speed of 3600 RPM or lower.

Installation Notes

Grinding wheel mounting should be performed by a qualified machinist or maintenance technician following ANSI B11.9 and OSHA 1910.215 standards for abrasive wheel machinery. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum RPM. Flanges and blotters must be clean, flat, and properly matched to the wheel diameter.
