Tru-maxx 66253255675 Surface Grinding Wheel 60 Grit

Product Description

The TRU-MAXX 66253255675 is a Type 1 surface grinding wheel designed for precision material removal on surface grinders in machine shops and metalworking environments. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond, delivering consistent stock removal and a predictable wear pattern. Key specs include a 60 grit rating, I hardness code, and a grain structure of 6, placing it in the medium-soft range suited for harder workpiece materials. At 2 pounds, it is sized for standard horizontal-spindle surface grinders. Licensed machinists and grinding technicians are the primary users of this wheel.

This wheel is intended for surface grinding operations on ferrous metals and tool steels where a medium-fine finish is required. The vitrified bond provides good porosity control and rigidity during flat surface grinding passes. The pink aluminum oxide abrasive is semi-friable, meaning it self-sharpens at a controlled rate, helping maintain cut rate over the wheel's service life. It is suited for use in production and toolroom environments running horizontal-spindle, reciprocating-table surface grinders.

Key Features

• Type 1 straight wheel profile — no recess, compatible with standard surface grinder flanges
• 60 grit aluminum oxide abrasive for medium stock removal with a controlled surface finish
• I hardness (soft) rating — recommended for grinding harder workpiece materials
• Vitrified bond construction for rigidity and thermal stability during grinding passes
• Semi-friable grain promotes self-sharpening action and extended wheel life
• Rated to 3600 RPM maximum operating speed

Compatibility

Designed as an OEM-style replacement surface grinding wheel for horizontal-spindle surface grinders accepting a 7-inch diameter, 1-inch to 1-1/4-inch bore wheel with a Type 1 straight profile.

Installation Notes

Surface grinding wheels must be installed by a qualified machinist or grinding technician following ANSI B7.1 safety standards. Always perform a ring test before mounting and inspect the wheel for cracks or chips. Power down and lock out the grinder before changing wheels. Do not exceed the 3600 RPM maximum speed rating stamped on the wheel.
