13H604 - Walter 6-Inch Saucer Cup Brush Knotted Steel 5/8-11 Arbor

Aggressive Weld Cleaning for Professional Fabricators

When it comes to post-weld cleaning and surface preparation, the Walter 13H604 6" Saucer Cup Brush is a powerhouse tool built for the professional welder. Standard wire brushes often struggle to get into the tight geometry of fillet welds or inside corners, forcing you to change tools or settle for a subpar clean. Walter solved this problem with the Saucer-Cup design. By angling the bristles, this brush allows you to attack the work surface at a natural 45-degree angle, driving the knotted wire tips directly into the root of the weld or the corner of the joint.

This brush features heavy-duty .020" carbon steel wire, twisted into robust knots. This construction is specifically designed for high-impact applications. If you are dealing with stubborn slag, thick mill scale, or heavy rust on structural beams, the aggressive action of the 13H604 will strip it down to bare metal quickly. The knotted style prevents the wires from bending back too easily, ensuring that the brush maintains its aggressive bite throughout its lifespan. It is the ideal companion for your 6-inch or larger angle grinder, threading directly onto the spindle with a standard 5/8"-11 hub.

Durability is a hallmark of the Walter brand. These brushes are manufactured with strict quality control to ensure perfect rotational balance. A balanced brush means less bouncing on the workpiece, which translates to a safer operation and a cleaner finish. It also means less wear and tear on your grinder's gears and bearings. For welders who demand tools that work as hard as they do, the Walter Saucer-Cup brush offers the reliability and efficiency needed to keep production moving.

• Cleaning fillet welds and lap joints.
