OVERVIEW

Superior Cleaning for Weld Prep and Finishing

For welders, surface preparation is the foundation of a quality weld. The Walter 13D302 3" Crimped Wire Cup Brush is an essential tool for ensuring your base material is free of contaminants before you strike an arc. Specifically designed for use on steel, this cup brush excels at removing surface rust, mill scale, old paint, and spatter. The crimped wire design offers a degree of flexibility that allows the brush to conform to irregular surfaces and contours, ensuring a thorough clean without removing excessive base metal.

What sets this brush apart is the integrated safety supporting ring. In aggressive grinding environments, wire brushes often fail due to wire fatigue and flaring. The supporting ring on the 13D302 counteracts this by holding the wires in a tight formation, concentrating the brushing action where it is needed most. As you work and the wire wears down, you simply remove the ring to unleash a second life for the brush. This feature is a game-changer for welders who are tired of throwing away brushes that still have usable wire left but have become too flared to be effective.

This model comes equipped with an M14 x 2.0 thread, making it compatible with grinders featuring metric spindles. It is crucial to check your grinder's spindle size, as this will not fit standard 5/8"-11 North American spindles. For those with the correct equipment, this brush offers perfectly balanced rotation. A balanced brush means less wobble and vibration, allowing for greater control when cleaning delicate areas or preparing bevels. The oil-hardened carbon steel wires are tough enough to handle the heat generated during aggressive cleaning, ensuring they don't snap or fly off prematurely.

Add the Walter 13D302 to your welding arsenal for reliable, safe, and cost-effective surface finishing. Whether you are cleaning up a repair job or prepping structural steel, this brush provides the performance professional welders trust.

FAQ

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

The safety supporting ring prevents the wires from flaring out too quickly, which keeps the brushing action aggressive and safe. Once the wire wears down to the ring, the ring can be removed to expose more wire, extending the brush's life.

This brush uses carbon steel wire and is recommended for use on steel. Using it on stainless steel or aluminum can cause cross-contamination and rust issues (after-rust). For stainless or aluminum, look for a stainless steel (304/316) wire brush.

The maximum rated speed for this 3-inch cup brush is 12,000 RPM. Always ensure your grinder's speed does not exceed this rating.

Crimped wire is more flexible and less aggressive than knotted wire. It is ideal for light to medium cleaning, surface finishing, and paint removal where you want to avoid removing base material. Knotted wire is better for heavy-duty slag and scale removal.

Once the wires have worn down flush with the ring, the ring can typically be knocked off using a hammer and a punch or a similar tool to dislodge it from the cup base, exposing the remaining wire.

This is a 3-inch (75mm) diameter cup brush.

Walter balances their brushes to ensure smooth operation. An unbalanced brush causes vibration, which leads to operator fatigue, poor finish quality, and premature wear on the grinder's bearings.
