Cratex 80388 Surface Grinding Wheel 4 in 46 Grit

Product Description

The CRATEX 80388 is a surface grinding wheel designed for material removal and surface finishing in industrial and trade shop applications. Measuring 4 inches in diameter and 1/4 inch thick, this wheel mounts on a 1/2 inch arbor hole and is rated at 46 grit, placing it in the coarse grade category. Coarse grit wheels are suited for aggressive stock removal on ferrous and non-ferrous metals, welds, castings, and rough surfaces where speed of cut matters more than finish quality. Machinists, fabricators, and maintenance technicians are the primary users of this wheel type.

This wheel is intended for use on bench grinders, pedestal grinders, and compatible surface grinding equipment that accepts a 4 inch diameter wheel with a 1/2 inch arbor. The 46 grit coarse grade makes it well suited for deburring, weld blending, casting cleanup, and initial stock reduction on steel, iron, and similar hard materials. It is packaged and sold individually and is appropriate for both shop and field maintenance use.
