Walter Surface Technologies 15X455 Fiber Disc 50 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 15X455 is a 4-1/2-inch ceramic fiber disc engineered for aggressive coated abrasive grinding and blending on metal surfaces. Part of the Cool Cut XX series, this disc uses a ceramic abrasive grain bonded with a resinoid bond to a fiber backing, delivering fast stock removal with a coarse 50-grit cut. It is rated to a maximum of 13,300 RPM and is designed for use with standard angle grinders equipped with an arbor hole attachment. Metalworking professionals, fabricators, and pipefitters rely on this type of disc for weld grinding, surface preparation, and edge work where consistent cut rate and disc longevity matter.

This disc is suited for heavy-duty grinding applications in fabrication shops, structural steel work, and maintenance environments. The ceramic grain construction supports use on carbon steel, stainless steel, and other hard metals where high material removal rates are required. The fiber backing provides rigidity and durability under sustained pressure. At 50 grit, it is positioned for coarse stock removal rather than finishing work. The orange disc color is specific to the Cool Cut XX series for quick visual identification on the job.

Installation Notes

This disc should be mounted and used by trained personnel following ANSI B7.1 and applicable shop safety standards. Always inspect the disc for damage before mounting and confirm the grinder RPM rating meets or exceeds the disc maximum before operation. Wear appropriate PPE including eye protection, gloves, and a face shield. Never exceed the 13,300 RPM maximum operating speed marked for this disc.
