01A532 - Walter SST+ 1/2-Inch Cobalt Blend Drill Bit for Stainless Steel

Premium Performance for Industrial Drilling

The Walter 01A532 1/2" SST+ Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Designed to address the common challenges associated with drilling hard metals, this tool features a proprietary cobalt blend substrate. This material composition provides exceptional hot hardness, allowing the bit to maintain its cutting edge even under the high temperatures generated when drilling stainless steel and other tough alloys. Unlike standard high-speed steel bits that dull rapidly in these applications, the SST+ series is engineered to withstand thermal stress, ensuring consistent performance over a longer service life.

A key technical advantage of this drill bit is its exclusive Bronze SST surface treatment. This specialized coating reduces friction at the cutting interface, which not only lowers operating temperatures but also facilitates smoother cutting action. Combined with a heavy-duty, fully ground body construction, the bit offers superior rigidity and concentricity. This structural integrity minimizes runout, resulting in more precise holes and reduced wear on the drill motor bearings. The geometry of the bit includes a "High Flow" flute design, specifically engineered to expedite chip evacuation. Efficient chip removal is critical in deep hole drilling to prevent packing and heat buildup, further enhancing the tool's efficiency.

This 1/2-inch drill bit is versatile enough for a wide array of machining environments. It performs reliably in both portable power tools used for on-site repairs and stationary drill presses found in machine shops. Whether the workpiece is mild steel, non-ferrous metal, or hardened stainless steel, the Walter SST+ delivers the torque transfer and cutting aggression required for professional results. By integrating advanced metallurgy with precision grinding, Walter provides a solution that significantly reduces cycle times and increases productivity in demanding MRO environments.
