Walter Surface Technologies 15L453 Type 29 Grinding Wheel

Product Description

The WALTER SURFACE TECHNOLOGIES 15L453 is a Type 29 depressed center grinding wheel designed for aggressive material removal on angle grinders. The wheel measures 4.5 inches in diameter with a 5/8 inch center hole and 5/8-11 threaded connector. It uses an aluminum oxide abrasive at 36 grit, placing it in the coarse grade range for fast, heavy stock removal. Rated to a maximum of 13,300 RPM, it is built for sustained use under load. This wheel is a standard choice for fabricators, welders, and metalworkers who need reliable cutting action across multiple metal types.

The 15L453 is suited for grinding aluminum, non-ferrous metals, stainless steel, and carbon steel. Its Type 29 conical profile provides an aggressive contact angle, which improves material removal rates compared to flat Type 27 wheels. This makes it well-suited for weld blending, surface preparation, and deburring work on structural and sheet metal fabrication projects. It mounts directly to angle grinders equipped with a 5/8-11 threaded spindle, which is the standard configuration found on most 4.5 inch angle grinders used in industrial and field applications.
