48L646 - Walter Knot Twisted Wire Cup Brush with Safety Ring

Precision Engineered for Heavy-Duty Surface Preparation

The Walter Surface Technologies Knot Twisted Wire Cup Brush represents the pinnacle of abrasive wire technology, designed specifically for the most demanding industrial environments. At the core of its performance is the proprietary oil-hardened and tempered wire, which ensures consistent metallurgical properties and exceptional fatigue resistance. This attention to material science results in a brush that maintains its aggressive cutting action over a significantly longer service life compared to standard commodity brushes.

A defining feature of the 48-L series is the integrated safety supporting ring. This mechanical innovation serves a dual purpose: it tightly controls the flaring of the wire knots during high-RPM operation, and it provides structural support to prevent premature wire breakage at the ferrule. As the wire wears down, the user can easily remove the ring, exposing fresh wire length and effectively doubling the usable life of the brush. This system not only enhances safety by reducing the likelihood of thrown wires but also optimizes the economic value of the consumable.

Ideally suited for large surface areas, this cup brush excels in removing heavy scale, rust, paint, and weld slag. Its knot-twisted construction delivers high-impact cleaning power, making it the tool of choice for structural steel fabrication, shipyard maintenance, and pipeline field work. The brush is precision-balanced to minimize vibration, protecting both the angle grinder's bearings and the operator from long-term fatigue.
