OVERVIEW

Aggressive Surface Preparation for Professionals

Tackle the toughest cleaning jobs with the Walter 3" Knot-Twisted Stainless Steel Cup Brush. Designed for professional welders and fabricators, this tool transforms the arduous task of surface cleaning into a quick and efficient process. The brush utilizes tightly twisted knots of stainless steel wire, creating a rigid and aggressive face that digs deep to remove contaminants. It is the ideal solution for stripping away heavy slag, cleaning root passes, or removing oxidation from stainless steel surfaces without compromising the base material's integrity.

Precision Engineering for Safety and Comfort
Safety and comfort are paramount in high-speed grinding operations. Walter Surface Technologies engineers every brush with internal balancing to ensure smooth rotation even at high RPMs. This attention to detail prevents the "bouncing" effect often seen with inferior brushes, allowing the operator to maintain steady control and achieve a uniform surface profile. The stainless steel composition is strictly controlled to ensure it meets the requirements for working on exotic metals and stainless grades, preventing the introduction of ferrous contaminants that could lead to costly rework.

Specific Fitment for Metric Tools
This model (13F312) comes equipped with an M14 x 2.0 integrated nut. This specific threading is intended for angle grinders with metric spindles, common in many high-end power tool brands. The direct-mount design simplifies tool changes—just spin it on and tighten—eliminating the need for separate adapters or locking nuts. The cup shape is perfect for flat or slightly curved surfaces, providing a wide contact patch that speeds up workflow.

From removing heat discoloration to prepping for painting or polishing, this Walter cup brush stands up to the rigors of daily industrial use. Its robust construction ensures long wire life and consistent performance, making it a staple accessory in any professional welding rig or metalworking shop.

FAQ

This brush features an M14 x 2.0 metric thread. Please check your angle grinder spindle to ensure compatibility, as this is different from the standard 5/8"-11 thread.

Yes, you can use it on carbon steel, but it is not recommended if you plan to use the same brush on stainless steel later. Using it on carbon steel will contaminate the brush, which can then transfer rust to stainless steel parts.

Knot-twisted brushes are much more aggressive and rigid. They are designed for heavy-duty cleaning, such as removing thick scale, heavy rust, or weld spatter. Crimped brushes are better for lighter cleaning and surface finishing.

Yes, stainless steel brushes are generally safe for use on aluminum to prevent ferrous contamination, although dedicated aluminum brushes are sometimes preferred to prevent loading.

This is a 3-inch diameter cup brush, suitable for use on compatible angle grinders.

Absolutely. Always wear a face shield, safety glasses, gloves, and protective clothing. Wire brushes can shed wires at high speeds, which can be dangerous.

Internal balancing ensures the brush spins smoothly without vibration. This reduces operator fatigue, protects the grinder bearings, and provides a more consistent cleaning action.
