Tru-maxx 66253269956 Grinding Wheel 6in 60 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253269956 is a Type 1 bench and pedestal grinding wheel designed for material removal and tool sharpening on stationary grinders. Built from aluminum oxide abrasive with a vitrified bond, it delivers consistent stock removal on ferrous metals including carbon steel and tool steel. The wheel measures 6 inches in diameter, 1/2 inch thick, with a 1-inch arbor hole. It carries a medium grade (hardness rating O) and a 60-grit designation, making it suitable for general-purpose grinding tasks. Maximum operating speed is 5,410 RPM. Specification code 27A60O6V13 confirms wheel composition and bond for procurement and safety documentation.

This wheel fits standard 6-inch bench grinders and pedestal grinders found in maintenance shops, tool rooms, fabrication facilities, and trade service vehicles. It is well suited for sharpening drill bits, chisels, and tool steel, as well as deburring and shaping ferrous metal workpieces. The 60-grit medium grade removes material efficiently without excessive wheel loading, making it a practical choice for everyday shop grinding tasks performed by machinists, maintenance technicians, and trade professionals.

Key Features

• 60-grit medium grade aluminum oxide abrasive for general-purpose ferrous metal grinding
• Vitrified bond provides rigidity and consistent cut rate throughout wheel life
• Semi-friable grain structure continuously exposes fresh cutting edges as the wheel wears
• Non-porous construction resists loading when grinding steel and similar materials
• Type 1 straight wheel profile fits standard bench and pedestal grinder flanges
• Specification code 27A60O6V13 supports safety compliance and replacement documentation

Compatibility

Designed as a direct-fit replacement for standard 6-inch bench and pedestal grinders that accept a Type 1 straight wheel with a 1-inch arbor hole.

Installation Notes

Bench and pedestal grinding wheels must be installed and dressed by qualified personnel following ANSI B7.1 safety standards for abrasive wheels. Before mounting, power down and lockout the grinder per OSHA lockout/tagout procedures. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the 5,410 RPM maximum speed rating stamped or marked on the wheel. Ensure flange diameter, blotters, and arbor bushing sizing comply with the grinder manufacturer's specifications before operating.
