Walter 3-Inch Stainless Steel Cup Brush with Ring, M14 Thread

Essential Weld Cleaning for Stainless Steel

For welders working with stainless steel or aluminum, cross-contamination is a major concern. Using a carbon steel brush on exotic metals can embed iron particles, leading to rust and failed inspections. The Walter 13G312 3" Stainless Steel Cup Brush is the solution. Built with high-grade 304 stainless steel wire, it is perfectly suited for pre-weld cleaning and post-weld discoloration removal on non-ferrous metals. It effectively removes slag, spatter, and oxidation without compromising the base material's corrosion resistance.

This brush is equipped with an M14 x 2.0 thread, designed for angle grinders with metric spindles. It is crucial to check your grinder's spindle size before purchasing, as this differs from the standard 5/8"-11 thread found on many North American tools. For shops equipped with metric tools, this brush offers a direct, secure fit that ensures safety and optimal power transmission.

Durability is key in heavy fabrication. The 13G312 features a unique safety supporting ring that holds the crimped wires in place. This prevents the wires from splaying out too early, keeping the brushing action concentrated and aggressive where you need it. It is ideal for cleaning large, flat weldments, preparing surfaces for painting, or deburring cut edges. The crimped wire style is less aggressive than a knotted wheel, leaving a smoother finish that is often desirable for cosmetic stainless steel work.

Application Versatility

Whether you are working in a shipyard, a food processing equipment plant, or an architectural metal shop, this brush handles the workload. Its rotational balance is superior to many competitors, reducing the 'hand-arm vibration' syndrome often associated with long-term grinder use. Trust Walter's engineering to keep your welds clean and your workflow efficient.
