Tru-maxx 66253255654 Surface Grinding Wheel 7in 46 Grit

Product Description

The TRU-MAXX 66253255654 is a Type 1 surface grinding wheel designed for precision stock removal and surface finishing on ferrous metals and similar materials. Built with aluminum oxide abrasive in a vitrified bond, this wheel delivers consistent cutting action and maintains its shape through extended use. At 7 inches in diameter, 1/4 inch thick, and bored to a 1-1/4 inch hole size, it mounts to standard surface grinders and compatible bench or pedestal machines. The 46 grit coarse grade makes it well suited for aggressive material removal rather than finish passes. Rated to 3600 RPM, it carries a hardness code of I and a semi-friable grain structure rated at grade 6.

This wheel is used in metalworking and fabrication environments where flat surface grinding is required. Typical applications include tool room work, die grinding, weld cleanup, and general ferrous metal stock removal. The coarse 46 grit rating suits roughing operations where surface finish is a secondary concern to metal removal rate. It is appropriate for use by machinists, tool and die makers, and maintenance technicians working with conventional surface grinders in both light industrial and shop settings.

Compatibility

Designed as an OEM-style replacement or direct-use grinding wheel for surface grinders and bench grinders accepting a 7 inch diameter, 1/4 inch thick, Type 1 straight wheel with a 1-1/4 inch arbor bore.

Installation Notes

Surface grinding wheels must be installed by qualified personnel familiar with ANSI B11.9 and applicable shop safety standards. Always perform a ring test before mounting to check for cracks, and never exceed the 3600 RPM maximum speed rating. Ensure the machine arbor and flanges are clean and properly sized before mounting, and dress the wheel before the first cut. Power down and lock out the grinder before removing or installing any wheel.
