2.5-Inch (65mm) Twisted Cup Brush with Hex Mount

Brief Overview

This 2.5-inch twisted cup brush is built for rapid rust removal, paint stripping, and surface preparation on mild steel and cast iron. The twisted steel-wire construction delivers aggressive cutting action while maintaining control on flat and slightly contoured surfaces. Designed to mount directly onto standard angle grinders and rotary tools via the hexagonal nut arbor, this brush is an essential workhorse for fabrication shops, maintenance teams, and restoration operations. For alternative wire configurations, consider larger diameter brushes or knotted-style alternatives that may suit different applications or aggressive rust conditions.

Key Features

• Twisted Steel-Wire Construction: Individual twisted tufts provide consistent cutting action and extended brush life compared to straight-wire designs
• 2.5-Inch (65mm) Cup Diameter: Optimal balance of coverage and control for hand-held power tools
• Hexagonal Threaded Mount: Direct attachment to standard arbor spindles on angle grinders and rotary tools; no adapter required
• Metallic Gray Wire Bristles: High-quality steel wires resist matting and maintain aggressive properties through extended use
• Cup Shape Design: Concentrates wire action on flat and slightly curved surfaces; ideal for edge work and corner access
