Weiler 90315 Cup Brush 1.75 in Steel Crimped Wire

Product Description

The WEILER 90315 is a crimped-wire cup brush designed for use with angle grinders and rotary tools in surface preparation, deburring, and weld cleaning applications. The brush features a 1.75-inch diameter with 0.006-inch steel crimped wire fill and a 0.25-inch straight shank arbor for secure mounting. With a maximum rated speed of 13,000 RPM, it delivers consistent material removal on metal surfaces. The 0.75-inch trim length provides controlled wire contact and moderate flexibility during use. This cup brush is appropriate for use by HVAC technicians, pipefitters, welders, plumbers, and general metal tradespeople who require fast surface conditioning or rust removal.

This cup brush is suited for light to medium surface prep tasks on ferrous metals, including removing mill scale, rust, and light corrosion. The crimped wire construction provides a more flexible, blending action compared to knotted wire, making it well-suited for contoured surfaces and weld seam cleanup. It mounts directly to rotary tools and right-angle die grinders equipped with a 0.25-inch collet or chuck. The compact 1.75-inch diameter allows access in tighter work areas typical of pipe joints, valve bodies, and fitting connections.

Installation Notes

Installation and use of cup brushes should be performed by qualified tradespeople familiar with abrasive tool safety. Always confirm the tool RPM rating meets or exceeds the 13,000 RPM maximum stamped on the brush before mounting. Ensure the tool is fully powered off and isolated before attaching or removing the brush. Eye protection and appropriate personal protective equipment are required during operation in accordance with applicable safety standards.
