13H404 Saucer-Cup Brush

The Walter 13H404 is a knot-twisted carbon steel wire brush designed for abrasive finishing on pneumatic or hydraulic power tools. Its 45-degree working angle helps operators reach inside corners, contours, and edges during surface preparation tasks.

Oil-hardened tempered wires

The brush uses oil-hardened and tempered wires that deliver aggressive brushing action for deburring and removing impurities from steel surfaces. The tightly knotted, twisted construction keeps the wires perfectly balanced to reduce vibration during operation.

Metal fabrication and maintenance

This brush suits welders and fabricators cleaning weld seams or preparing steel for coating. It is not intended for non-metallic materials or precision polishing where a softer media is required.

Questions about this item

How long do the oil-hardened carbon-steel wires last before the brush needs replacing?

The oil-hardened and tempered carbon-steel wires are built for aggressive brushing action; replacement timing depends on how often you use the brush on steel surfaces for deburring or cleaning.

What limits continuous operation of the 45-degree saucer-cup design?

The 45-degree working angle lets the knot-twisted wires reach inside corners and contours; the practical limit is wire wear from sustained contact with metal rather than a thermal or duty-cycle restriction.

Does the brush generate noticeable heat or vibration during all-day use on steel?

The balanced knot-twisted construction reduces vibration, and because the tool has no motor the only heat comes from friction between the carbon-steel wires and the workpiece.
