Tru-maxx 66253269924 Surface Grinding Wheel 60 Grit 7 in

Product Description

The TRU-MAXX 66253269924 is a Type 1 surface grinding wheel designed for precision flat-surface stock removal on ferrous metals and hard materials. It measures 7 inches in diameter and 1/2 inch thick, with a 1-1/4 inch arbor hole for standard spindle mounting. The abrasive is aluminum oxide at 60 grit, which places it in the medium grade range — aggressive enough for rapid material removal while still leaving a workable surface finish. Rated to a maximum of 3600 RPM, this wheel is suited for bench grinders and surface grinders used in machine shops, tool rooms, and maintenance environments. It weighs 1.4 pounds and features a non-porous, ruby-colored wheel body with an I hardness code.

This wheel is used in applications requiring controlled surface stock removal, deburring, and sharpening of tooling on fixed grinding equipment. The 60-grit aluminum oxide construction is a common choice for general-purpose grinding of carbon steel, alloy steel, and similar ferrous workpieces. It is a straight, flat-face Type 1 configuration with no recess, making it appropriate for surface grinding setups where the full wheel face contacts the workpiece. Machinists, tool and die makers, and maintenance technicians are the typical installers and operators of this wheel.

Compatibility

Designed as a standard Type 1 replacement or service wheel for bench grinders and surface grinders with a 7-inch wheel capacity and a 1-1/4 inch spindle arbor.

Installation Notes

Wheel mounting and dressing must be performed by qualified personnel following ANSI B7.1 safe-use guidelines for abrasive wheels. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting and perform a ring test; do not use a wheel that produces a dull thud instead of a clear tone. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
