Tru-maxx 66253269710 Grinding Wheel 6in 80 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253269710 is a Type 1 bench and pedestal grinding wheel designed for general-purpose stock removal and tool sharpening on stationary bench grinders and pedestal grinders. The wheel measures 6 inches in diameter, 1 inch thick, with a 1-inch arbor hole. It is made from aluminum oxide abrasive bonded with a vitrified bond at a medium grade (hardness O) and 80 grit, making it well suited for grinding ferrous metals, carbon steel, and high-speed steel tooling. Rated to a maximum of 5,410 RPM, this wheel carries a semi-friable grain structure at grain structure rating 6, providing consistent cut and controlled wear through a standard work cycle. It weighs 2.24 pounds. Specification code 27A80O6V13.

This wheel is used in machine shops, maintenance facilities, welding shops, and trade service environments where bench or pedestal grinders are part of the daily workflow. Typical applications include resharpening drill bits and lathe tools, deburring steel parts, and shaping tool edges. The 80-grit medium grade balances material removal rate with surface finish, making it appropriate for both rough shaping and finish grinding on steel and other ferrous materials. It is installed and used by machinists, tool-and-die workers, maintenance technicians, and trade professionals across HVAC, plumbing, and general mechanical service.

Key Features

• Vitrified bond construction provides rigidity and consistent wheel breakdown during use
• Semi-friable grain structure supports self-sharpening action and extended wheel life
• Non-porous wheel body minimizes loading when grinding steel
• 5,410 maximum RPM rating for use on standard bench and pedestal grinders
• Type 1 straight-wheel profile fits standard arbor flanges with 1-inch bore

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for bench grinders and pedestal grinders accepting a 6-inch diameter, 1-inch thick, Type 1 straight wheel with a 1-inch arbor hole. No bushing is included.

Installation Notes

Grinding wheel installation and dressing should be performed by a qualified technician following ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation using the ring test, and never exceed the maximum RPM stamped on the wheel. Ensure flanges are clean, properly sized, and that blotters are in place before tightening the arbor nut.
