OVERVIEW

Premium Surface Finishing with Walter Technology

The Walter 13G312 is a high-performance 3-inch wire cup brush engineered for professionals who demand precision and longevity in their abrasive tools. Manufactured by Walter Surface Technologies, this brush is distinguished by its use of superior oil-hardened and tempered stainless steel wires. Unlike standard carbon steel brushes, this unit is specifically designed for use on stainless steel and aluminum surfaces, ensuring that the workpiece remains free from ferrous contamination and rust bloom after processing.

One of the standout features of this model is the integrated safety supporting ring. In standard cup brushes, wires tend to flare outwards under centrifugal force, reducing the effective contact area and creating safety hazards. Walter's supporting ring constrains the wires, maintaining a tight, dense brush face that delivers aggressive cleaning action while preventing premature wire fatigue. As the brush wears down, the user can remove the ring to expose fresh wire length, effectively giving the tool a second life and maximizing value.

This specific model features an M14 x 2.0 threaded arbor, making it compatible with angle grinders utilizing metric spindles. The internal construction is meticulously balanced to ensure concentricity, which drastically reduces vibration during operation. Less vibration means less operator fatigue and a smoother finish on the material. Whether you are removing paint, rust, or scale from large flat surfaces, the 13G312 delivers consistent, high-quality results.

Technical Excellence

Walter's commitment to quality is evident in the wire positioning. Each tuft is anchored securely to prevent fly-off, a common issue with inferior brushes. The crimped wire design offers a degree of flexibility, allowing the brush to conform slightly to surface irregularities while still providing enough stiffness for effective removal of surface contaminants. This balance of aggression and control makes it an essential tool for industrial MRO environments.

FAQ

This brush has an M14 x 2.0 metric thread. Please verify your angle grinder spindle size, as this is different from the standard 5/8"-11 thread.

While it will work, it is not recommended. Using a stainless steel brush on carbon steel is an unnecessary expense, and if you later use the same brush on stainless steel, you will contaminate the stainless with iron particles.

The supporting ring prevents the wires from flaring out under centrifugal force, keeping the brush face dense for more aggressive cleaning and extending the wire life.

This is a crimped wire brush. Crimped wire is generally more flexible and leaves a smoother finish compared to the high-impact action of knotted wire brushes.

The maximum rated speed is 12,000 RPM. Always ensure your grinder's speed does not exceed this rating for safety.

Yes, the stainless steel wires are safe for use on aluminum and will not cause rust contamination like carbon steel brushes would.

Once the wires have worn down to the level of the ring, the ring can be removed to expose the remaining length of the wire for continued use.

This is a 3-inch diameter cup brush, suitable for use on standard 4.5-inch or 5-inch angle grinders (provided they have an M14 spindle).
