Norton 66253246817 Surface Grinding Wheel 46 Grit 16 in

Product Description

The NORTON 66253246817 is a Type 1 vitrified aluminum oxide surface grinding wheel built for heavy-stock removal on ferrous and non-ferrous metals. It measures 16 inches in diameter, 2 inches thick, with a 5-inch arbor hole, and carries a coarse 46-grit rating with an I hardness code. The vitrified bond provides rigid, consistent cutting action and good thermal resistance during extended grinding passes. At a maximum operating speed of 2,030 RPM, this wheel is suited for production-volume grinding on surface grinders and cylindrical grinders in machine shops and tool rooms. Weighing 14.93 pounds, it is a substantial wheel intended for professional-grade equipment.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Its coarse 46-grit aluminum oxide abrasive makes it effective for rapid material removal on a wide range of workpiece materials including hard and soft carbon steels, 400 series stainless steel, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a standard straight wheel with no recess and no taper, making it straightforward to mount on compatible spindles and flanges.

Installation Notes

Grinding wheel installation and dressing should be performed by a qualified machinist or grinding equipment operator following ANSI B7.1 safety standards. Always power down and lock out the grinder before mounting or changing the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test to confirm structural integrity. Never exceed the maximum rated RPM of 2,030 and confirm that the machine spindle speed is set correctly before starting the grinder.
