Tru-maxx 66253255173 Grinding Wheel 10in 120 Grit

Product Description

The TRU-MAXX 66253255173 is a Type 1 bench and pedestal grinding wheel designed for precision stock removal and tool sharpening on stationary bench grinders and pedestal grinders. It measures 10 inches in diameter and 1 inch thick with a 1-1/4 inch hole diameter. The wheel is bonded with a vitrified bond and made from aluminum oxide abrasive, rated at a medium-hard P hardness grade with a grain structure of 5. At 120 grit, this wheel is suited for fine finishing and edge refinement on ferrous metals. It carries a maximum operating speed of 3,250 RPM and weighs 8.2 pounds.

This grinding wheel is intended for use on bench grinders and pedestal grinders in machine shops, tool rooms, maintenance departments, and fabrication facilities. It is well-suited for sharpening tools, dressing cutting edges, and light to moderate material removal on steel and other ferrous workpieces. The semi-friable aluminum oxide abrasive self-sharpens during use, maintaining consistent cut throughout the wheel's service life. No bushing is included, so confirm arbor compatibility before installation.

Installation Notes

Installation should be performed by a qualified machine operator or maintenance technician familiar with ANSI B7.1 grinding wheel safety standards. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum rated RPM of 3,250. Eye protection and a properly adjusted tool rest and wheel guard are required during operation.
