Tru-maxx 66253255464 Surface Grinding Wheel 8in 60G

Product Description

The TRU-MAXX 66253255464 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous metals and general-purpose bench or surface grinder applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, controlled cutting action at medium grade with an H hardness rating. It measures 8 inches in diameter, 1/2 inch thick, and accepts a 1-1/4 inch arbor hole. The semi-friable grain structure allows for self-sharpening behavior during use, reducing glazing and maintaining cut rate over the wheel's life. Rated to a maximum of 3600 RPM, it is appropriate for standard surface and bench grinding equipment found in machine shops and fabrication environments.

This wheel is suited for surface grinder and bench grinder setups in machine shops, tool rooms, and fabrication facilities. The 60 grit and H hardness combination makes it appropriate for moderate material removal on carbon steel, alloy steel, and similar ferrous workpieces where finish and dimensional accuracy are both relevant. It is a non-porous, white aluminum oxide wheel with no recess, intended for straight-wheel mounting configurations common in industrial and trade shop settings.

Compatibility

Designed as a standard Type 1 straight grinding wheel for use on surface grinders and bench grinders with an 8 inch wheel capacity, 1-1/4 inch arbor, and a maximum spindle speed of 3600 RPM or lower.

Installation Notes

Grinding wheel installation should be performed by a qualified machinist or toolroom technician following ANSI B7.1 safety requirements. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips using a ring test before mounting, and never exceed the maximum RPM rating stamped on the wheel. Use proper flanges and blotters and confirm arbor hole fit before operating.
