K3179-1 - Lincoln Electric 3x7 Row Stainless Steel Toothbrush Style Wire Brush

Precision Cleaning for Stainless Steel Applications

The Lincoln Electric K3179-1 Stainless Steel Wire Brush is a specialized manual cleaning tool designed for the rigorous demands of industrial welding and fabrication. Engineered with high-quality stainless steel bristles, this brush is essential for maintaining the corrosion resistance of stainless steel base metals by preventing the introduction of free iron and other contaminants often associated with carbon steel brushes. The bristles are arranged in a dense 3 x 7 row configuration, providing an optimal balance between aggressive cleaning action and surface preservation.

Measuring 7.5 inches in overall length with a block size of 0.45 inches, the K3179-1 features a "toothbrush" style handle. This ergonomic design is specifically intended to facilitate access to confined spaces, corners, and complex weld geometries that standard scratch brushes cannot effectively reach. It is particularly effective for inter-pass cleaning, removal of light slag, and surface preparation prior to welding. The handle geometry allows for precise manipulation, ensuring that the operator can apply targeted pressure to specific areas of the heat-affected zone (HAZ) or weld bead without damaging surrounding surfaces.

In professional MRO and fabrication environments, the use of dedicated stainless steel brushes is a critical quality control measure. Using this Lincoln Electric brush ensures compliance with best practices for stainless steel welding, reducing the risk of post-weld rust and oxidation. The durable construction ensures the bristles retain their shape and stiffness over repeated use, making it a reliable component of any professional welder's toolkit.
