Weiler 14516 Cup Brush 6 in Nylon Crimped 120 Grit

Product Description

The WEILER 14516 is a 6-inch diameter crimped cup brush filled with nylon abrasive filaments loaded with 120-grit silicon carbide. It is designed for surface preparation, light deburring, blending, and cleaning on materials where a fine, controlled abrasive action is needed without aggressive metal removal. The brush mounts via a 5/8-11 threaded arbor hole with an internal nut and is rated for a maximum of 6,600 RPM. A trim length of 1.25 inches provides the filament exposure needed for consistent contact on contoured or flat workpiece surfaces. This tool is typically installed and operated by machinists, maintenance technicians, and fabricators working with angle grinders or bench grinders.

This cup brush is suited for fine finishing work on metal, composite, and similar hard surfaces in light industrial and maintenance environments. Its nylon fill with silicon carbide abrasive makes it appropriate for applications where steel wire brushes would cause excessive surface damage or contamination. Common use cases include weld seam blending, surface conditioning before coating, and light scale removal on aluminum, stainless steel, and other materials sensitive to ferrous contamination. It is sold individually and is a direct fit for grinders accepting a 5/8-11 threaded arbor.

Installation Notes

Power down and unplug or lock out the grinder before mounting or removing this brush. Thread the brush onto the 5/8-11 arbor and tighten the internal nut securely using the appropriate wrench. Always confirm the tool's no-load RPM rating does not exceed the 6,600 RPM maximum marked on this brush before operation. Wear appropriate PPE including eye protection and gloves; inspect the brush for damaged or splayed filaments before each use.
