Tru-maxx 66253269564 Surface Grinding Wheel 7in 46 Grit

Product Description

The TRU-MAXX 66253269564 is a Type 1 straight surface grinding wheel designed for precision material removal on surface grinders. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond, rated at a coarse 46 grit and I hardness code. With a semi-friable grain structure and porous construction, this wheel maintains consistent cut rates while resisting loading on ferrous metals. It is rated to a maximum of 3600 RPM and carries specification code 23A46I12V31. Machinists, tool grinders, and surface grinding operators are the primary installers and users of this wheel.

This wheel suits flat surface grinding applications in machine shops, maintenance facilities, and production environments. It performs on surface grinders where a coarse, free-cutting aluminum oxide wheel is appropriate for aggressive stock removal on steel, iron, and similar ferrous workpieces. The Type 1 straight profile fits standard surface grinder spindles with a 1-1/4 inch bore. Its coarse grit and soft-to-medium hardness rating make it well suited for rapid stock removal rather than fine finish work.

Key Features

• Type 1 straight wheel profile fits standard surface grinder spindles
• 46 grit coarse aluminum oxide abrasive for aggressive material removal
• Vitrified bond with porous construction resists loading and maintains wheel integrity
• I hardness code and semi-friable grain structure support consistent cut-rate retention
• Rated to 3600 RPM maximum operating speed
• Specification code 23A46I12V31 for cross-reference and replacement identification

Compatibility

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

Installation Notes

Surface grinding wheels must be installed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Ensure the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Guard the wheel properly and allow it to run free for at least one minute before engaging the workpiece.
