13F300 - Walter 3-Inch Knot-Twisted Wire Cup Brush M10x1.25 Thread

Heavy-Duty Surface Preparation with Walter Quality

The Walter 13F300 3-Inch Knot-Twisted Wire Cup Brush is a premium abrasive tool engineered for the most demanding industrial cleaning applications. Manufactured by Walter Surface Technologies, a leader in surface treatment solutions, this brush is designed to tackle tough tasks such as deburring, removing heavy rust, eliminating scale, and cleaning weld edges. The 13F300 features a specific M10 x 1.25 threaded arbor, making it compatible with angle grinders that utilize this specific spindle size, ensuring a secure and safe fit during high-speed operation.

What sets this brush apart is its construction. It utilizes top-quality, oil-hardened, and tempered steel wire. This manufacturing process ensures that each wire strand maintains its integrity and stiffness even under significant pressure and heat. The knot-twisted design bundles the wires together, creating a rigid and aggressive brushing face that digs deep into surfaces to remove stubborn contaminants that crimped wire brushes simply cannot handle. This makes it an essential tool for metal fabrication shops, shipyards, and maintenance departments where efficiency is paramount.

Operator safety and comfort are central to Walter's design philosophy. The 13F300 is precision-balanced to run smoothly without the excessive vibration often associated with standard wire brushes. Reduced vibration not only protects the operator from fatigue and long-term injury (such as white finger syndrome) but also reduces wear on the power tool's bearings. Whether you are prepping a surface for painting or cleaning up after a heavy weld, this cup brush delivers consistent, high-performance results.
