Tru-maxx 66253255222 Grinding Wheel 8in 46 Grit 3600 Rpm

Product Description

The TRU-MAXX 66253255222 is an 8-inch diameter, Type 1 bench and pedestal grinding wheel designed for material removal and tool dressing on stationary grinding equipment. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal on ferrous metals, tool steels, and general shop work. The wheel measures 1 inch thick with a 1-inch arbor hole and is rated to a maximum of 3600 RPM. Grit is 46 coarse with a hardness grade of O (medium), a grain structure of 6, and a semi-friable abrasive that fractures under load to expose fresh cutting edges. Licensed tradespeople and experienced shop technicians are the primary installers.

This wheel is suited for bench grinder and pedestal grinder applications in maintenance shops, fabrication environments, and tool-and-die work areas. The 46-grit coarse grade makes it appropriate for aggressive stock removal, edge shaping, and deburring operations rather than fine finishing. The non-porous, vitrified bond provides rigidity and resistance to heat and coolant, making it reliable for both dry and light wet grinding scenarios typical in industrial and trade settings.

Key Features

• 8-inch diameter, 1-inch thick Type 1 wheel with 1-inch arbor hole for standard bench and pedestal grinders
• Aluminum oxide abrasive, semi-friable — fractures under load to expose fresh cutting edges and maintain cut rate
• Vitrified bond provides structural rigidity and resistance to heat and shop fluids
• 46-grit coarse grade suited for aggressive stock removal and edge shaping on ferrous metals
• Hardness grade O (medium) with grain structure 6 for balanced wheel life and cut aggressiveness
• Rated to 3600 maximum RPM — matched to standard bench and pedestal grinder spindle speeds

Compatibility

Designed as a direct-fit replacement grinding wheel for standard bench grinders and pedestal grinders accepting an 8-inch diameter, 1-inch thick, Type 1 wheel with a 1-inch arbor hole. No bushing is included.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified technician following ANSI B11.9 and OSHA 29 CFR 1910.215 guidelines for abrasive wheel machinery. Before mounting, power down and lock out the grinder at the main disconnect. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the marked maximum RPM. Always dress the wheel after mounting to ensure proper balance and a true running surface before returning the machine to service.
