OVERVIEW

The Safe Way to Clean Stainless Welds

Fabricators know that using a carbon steel brush on stainless steel is a recipe for disaster, leading to "after-rust" and failed inspections. The Walter 3-Inch Stainless Steel Cup Brush (13D312) is built to solve this problem. With pure stainless steel bristles, it allows you to clean TIG and MIG welds, remove heat tint, and prep aluminum surfaces without the risk of cross-contamination. The crimped wire style is gentle enough to polish up the heat-affected zone (HAZ) without digging into the metal, leaving a smooth, clean surface ready for passivation or painting.

What sets this brush apart is the smart supporting ring around the bristles. Wire brushes naturally want to flare out when you spin them up, which makes them softer and less effective. Walter's ring keeps the wires tight and focused, giving you better cutting action. Even better, when you've worn the wires down to the ring, you don't have to throw the brush away. Just pop the ring off, and you've got a whole new section of wire ready to go. It's like getting two brushes for the price of one.

This model features an M14x2.0 thread, so be sure to check your grinder's spindle size before purchasing, as it differs from the standard 5/8-11 thread found on many North American tools. It is perfectly balanced to run smoothly, saving your hands from the numbness that comes with cheap, wobbly brushes. Whether you are cleaning tanks, architectural railings, or aluminum boat hulls, this brush delivers the professional finish your work deserves.

FAQ

This brush features an M14x2.0 metric thread. Please verify your angle grinder spindle size before purchasing.

Yes, it will work, but it is not recommended. Using a stainless brush on carbon steel is more expensive than necessary, and if you use it back on stainless steel afterwards, you will contaminate the stainless surface.

The supporting ring prevents the wires from flaring out too much during use. It can be removed once the wires wear down to expose fresh wire, extending the brush's life.

This model uses crimped wire, which provides a flexible brushing action ideal for surface cleaning and finishing rather than heavy material removal.

The brush has a diameter of 3 inches (75mm).

No, as long as the brush has not been previously used on carbon steel. The wires are made of stainless steel to prevent contamination.

Once the wire wears down flush with the ring, you can typically pry or knock the ring off using a suitable tool to expose the remaining wire length.

Always check the brush label for the specific Max RPM, but 3-inch cup brushes are typically rated for use with standard angle grinders (often around 12,000 RPM).
