Tru-maxx 66253269713 Grinding Wheel 7in 46 Grit Aluminum Oxide

Product Description

The TRU-MAXX 66253269713 is a Type 1 bench and pedestal grinding wheel designed for material removal and tool dressing on standard bench grinders and pedestal grinders. It measures 7 inches in diameter, 3/4 inches thick, with a 1-inch arbor hole. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond, rated at a coarse 46 grit and hardness grade O with a grain structure of 6. Maximum operating speed is 3,600 RPM. At 3.79 pounds, it is a solid, full-size wheel suited for maintenance shops, fabrication environments, and tool rooms where frequent grinding and sharpening tasks are performed by machinists, welders, and maintenance technicians.

This wheel fits 7-inch bench grinders and pedestal grinders commonly found in industrial maintenance, fabrication shops, and trade apprenticeship facilities. The 1-inch arbor hole accommodates standard spindle sizes on most bench and pedestal grinder models. The coarse 46-grit rating makes it well suited for aggressive stock removal on ferrous metals, tool steel, and general-purpose carbon steel workpieces. No bushing is included with this wheel, so verify the spindle diameter before installation.

Key Features

• 46 grit coarse aluminum oxide abrasive for aggressive material removal on ferrous metals
• Vitrified bond construction provides rigidity and consistent cut throughout wheel life
• Semi-friable grain structure self-sharpens during use to maintain cut rate
• Non-porous wheel minimizes loading when working softer steels
• Type 1 straight-wheel profile fits standard bench and pedestal grinder flanges
• Rated to 3,600 RPM maximum operating speed

Compatibility

Designed as a direct-fit replacement for standard 7-inch bench and pedestal grinders with a 1-inch arbor spindle. No bushing is included; reducers may be required for spindles smaller than 1 inch.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician following ANSI B7.1 safe use requirements for abrasive wheels. Always power down and lock out the grinder before changing the wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test by tapping lightly with a non-metallic object to confirm the wheel is sound. Do not exceed the 3,600 RPM maximum speed rating marked on the wheel, and ensure flange diameter and mounting hardware meet the grinder manufacturer specifications.
