Tru-maxx 66243496733 Type 7 Surface Grinding Wheel 46G

Product Description

The TRU-MAXX 66243496733 is a Type 7 recessed surface grinding wheel engineered for precision surface grinding operations on ferrous metals. Made from aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent, controllable stock removal at a coarse 46 grit. At 12 inches in diameter and 2 inches thick with a 5-inch arbor hole, it is sized for industrial surface grinders used in machine shops and maintenance grinding applications. The white aluminum oxide grain is semi-friable, meaning it self-sharpens during use to maintain cut rate and reduce heat buildup at the workpiece.

This wheel is suited for surface grinding operations in machine shops, tool rooms, and industrial maintenance environments. The Type 7 double-recessed configuration with two-side recessing and a 7.5-inch recess diameter accommodates compatible surface grinder spindle flanges. Coarse grit is appropriate for aggressive stock removal on flat surfaces, weld cleanup, and initial workpiece conditioning before finish grinding. Installation and operation are typically performed by machinists or skilled maintenance technicians on horizontal-spindle surface grinders rated for this wheel size and speed.

Key Features

• Aluminum oxide abrasive grain — effective on hardened steels and ferrous metals
• Vitrified bond construction for rigidity and consistent form holding
• Semi-friable grain structure promotes self-sharpening and cooler cutting
• Type 7 double-recessed profile with two-side recesses for spindle flange clearance
• Coarse 46 grit and J hardness rating suit aggressive stock removal applications
• Maximum operating speed rated at 2069 RPM — do not exceed

Compatibility

Designed for use on horizontal-spindle surface grinders accepting a Type 7 wheel with a 12-inch diameter, 2-inch face width, and 5-inch arbor bore. Verify that the machine spindle speed does not exceed the rated maximum of 2069 RPM before mounting.

Installation Notes

Grinding wheel installation must be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Before mounting, ring-test the wheel for cracks and confirm the machine's rated spindle speed does not exceed 2069 RPM. Power down and lock out the grinder before changing wheels, and use only properly matched flanges and blotters. Always dress the wheel with an appropriate diamond or rotary dresser before grinding to true the face and expose fresh abrasive grain.
