Cratex 40152 Surface Grinding Wheel 3in 80 Grit

Product Description

The CRATEX 40152 is a Type 1 surface grinding wheel designed for precision material removal on ferrous and non-ferrous workpieces. It measures 3 inches in diameter and 1/4 inch thick, with a 1/4 inch arbor hole. The abrasive matrix is aluminum oxide at 80 grit, rated medium hardness, and the wheel is approved for a maximum operating speed of 12,095 RPM. This wheel is suited for use on bench grinders, tool and cutter grinders, and surface grinders in machine shops, fabrication shops, and maintenance environments. It is typically installed and operated by machinists, tool and die makers, and skilled maintenance technicians.

This grinding wheel fits applications requiring controlled stock removal and moderate surface finishing. The 80 grit aluminum oxide composition performs well on steel, cast iron, and general-purpose metals. At 3 inches in diameter with no recess, the flat face profile suits straight surface grinding passes and off-hand tool sharpening. The compact size makes it appropriate for benchtop and portable grinder setups where a smaller wheel diameter is specified by the equipment manufacturer.

Installation Notes

Grinding wheels must be installed and dressed by a qualified operator following ANSI B7.1 safety standards. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting, and never exceed the rated maximum RPM of 12,095. Use the correct arbor flanges and blotters as specified by the grinder manufacturer, and run the wheel at operating speed in a guarded position for at least one minute before grinding.
