01B520 - Walter SST+ #20 Cobalt Jobber Drill Bit for Stainless Steel

High-Performance Drilling with Walter SST+ Technology

The Walter #20 SST+ Jobber Drill Bit (01B520) represents the pinnacle of drilling efficiency for industrial applications. Engineered by Walter Surface Technologies, this bit is designed to tackle the most demanding materials found in modern fabrication shops, including stainless steel, mild steel, and non-ferrous metals. The core of its performance lies in its premium cobalt blend construction, which provides exceptional hardness and heat resistance, allowing the bit to maintain its cutting edge far longer than standard high-speed steel alternatives.

Precision is paramount in professional environments, and the SST+ series delivers with its exclusive Speed Tip design. This self-centering geometry eliminates the need for center punching, even when drilling on round or curved surfaces, ensuring accurate hole placement every time. The bit also features a unique "High Flow" flute design that rapidly evacuates chips from the hole, preventing clogging and heat buildup that can work-harden sensitive materials like stainless steel.

Further enhancing its durability is the proprietary bronze SST surface treatment. This specialized coating acts as a lubricant, significantly reducing friction during the drilling process. Combined with a back-tapered body that prevents binding, the Walter #20 SST+ allows for higher drilling speeds and reduced operator fatigue. Whether utilized in a stationary drill press or a portable hand drill, this tool delivers consistent, high-quality results, making it an essential component of any MRO or fabrication toolkit.
