Cratex 80390 Surface Grinding Wheel 46 Grit Coarse

Product Description

The CRATEX 80390 is a surface grinding wheel designed for stock removal and surface finishing on ferrous and non-ferrous materials. It measures 4 inches in diameter, 1 inch thick, with a 1/2-inch arbor hole. The 46-grit coarse grade makes it well suited for aggressive material removal, deburring, and rough surface prep where a finer finish is not required. Machinists, fabricators, and tool and die workers install this wheel on compatible bench grinders and surface grinding machines. The arbor hole size accommodates standard spindle configurations common in light industrial and shop environments.

This grinding wheel is used in metalworking and fabrication shops for surface grinding operations on steel, cast iron, and similar workpiece materials. The coarse 46-grit rating removes material efficiently, making it appropriate for first-pass grinding, weld cleanup, and scale removal. It is a single-unit item with no minimum order quantity beyond one piece, suited for both shop stocking and individual job use.
