OVERVIEW

Achieve Superior Finishes with Walter Crimped Wire Brushes

Upgrade your metal cleaning and finishing capabilities with the Walter Allsteel 4" Crimped Saucer-Cup Brush. Designed for the discerning welder and fabricator, this tool (Model 13W431) brings professional-grade performance to your angle grinder. The innovative saucer-cup shape is a game-changer for anyone who has struggled to clean inside corners or along curved surfaces with a standard cup brush. By angling the bristles outward in a saucer profile, Walter allows you to approach the workpiece at a more natural angle, providing better coverage and control during intricate cleaning tasks.

The brush features premium crimped steel wires that excel at surface conditioning. Whether you are prepping a surface for welding, removing oxidation after a cut, or stripping old paint from a restoration project, the crimped action provides a thorough clean without digging into the metal. This makes it particularly useful for sheet metal work and finishing applications where maintaining the integrity of the surface profile is important. The 5/8"-11 threaded arbor screws directly onto your grinder's spindle, eliminating the need for locking nuts and ensuring a tight, slip-free fit that handles the torque of start-ups and heavy loads.

Walter Surface Technologies is renowned for producing brushes that run smoother and last longer. The 13W431 is no exception, boasting an impeccably balanced core that virtually eliminates the wobble and vibration found in lesser quality brushes. This smooth operation translates to cleaner finishes, less operator fatigue, and a safer working environment. The high-density wire fill ensures that fresh cutting edges are constantly available as the brush wears, maintaining consistent performance from the first use to the last. Add this versatile saucer-cup brush to your abrasive arsenal and experience the difference that quality engineering makes in your daily fabrication work.

FAQ

The saucer-cup shape allows the brush to access corners, contours, and hard-to-reach areas more effectively than a standard flat cup brush. It also permits a flatter angle of approach for better control.

This brush comes with a built-in 5/8"-11 threaded arbor, which is the standard spindle size for most 4-1/2" and 5" angle grinders.

While it can physically clean stainless steel, this 'Allsteel' brush uses carbon steel wire. Using it on stainless steel can leave carbon deposits that may lead to rust (cross-contamination). For stainless steel, it is recommended to use a brush with stainless steel wire.

The maximum safe operating speed for this brush is typically rated at 12,500 RPM. Always check the label on the brush itself to confirm and ensure your grinder does not exceed this speed.
