12D058 - Walter A-21 Stainless Steel Grinding Point

Precision Finishing for Stainless Steel Applications

The Walter A-21 Mounted Point (SKU: 12D058) represents a pinnacle in abrasive engineering, specifically formulated to address the unique challenges of grinding and finishing stainless steel. In industrial environments where precision and surface integrity are paramount, standard general-purpose abrasives often fail due to heat generation and material contamination. Walter Surface Technologies has developed this mounted point with a specialized bond and high-grade abrasive grain structure that promotes cool cutting action, significantly reducing the risk of thermal discoloration (blueing) on the workpiece.

The A-21 shape is a standard geometry in the abrasive industry, typically featuring a 1-inch diameter and 1-inch length, making it exceptionally versatile for accessing narrow areas, internal diameters, and contours that larger grinding wheels cannot reach. This product is manufactured with strict concentricity tolerances. A perfectly balanced tool is critical when operating at the high RPMs typical of die grinders; it prevents the "chatter" that ruins surface finishes and accelerates wear on the power tool's bearings. By ensuring vibration-free performance, Walter allows operators to maintain steady control for intricate deburring and shaping tasks.

Furthermore, the integrity of the abrasive composition ensures that the point breaks down at a controlled rate, constantly exposing fresh, sharp grain edges. This self-sharpening characteristic is vital for maintaining consistent material removal rates on tough alloys like stainless steel. Whether used for enlarging holes, smoothing weld seams in fittings, or general fabrication cleanup, the 12D058 offers a reliable, high-performance solution that aligns with the rigorous standards of modern metalworking facilities.
