01A526 - Walter SST+ 13/32 Inch Cobalt Drill Bit for Stainless Steel

Industrial Grade Precision with Walter SST+ Technology

The Walter 01A526 13/32" SST+ Drill Bit is engineered to meet the rigorous demands of industrial fabrication and maintenance. Manufactured by Walter Surface Technologies, the SST+ line is renowned for its ability to tackle the toughest materials, including stainless steel, with exceptional efficiency. At the core of this drill bit is a premium cobalt blend (M35), which provides superior red hardness. This allows the bit to maintain its cutting edge even under the high temperatures generated when drilling hard alloys, significantly extending tool life compared to standard high-speed steel bits.

Precision is paramount in the design of the SST+. It features a 135-degree split point geometry. Unlike standard 118-degree points, this split point design is self-centering, meaning it bites into the material immediately upon contact. This eliminates the common issue of "walking" or wandering across the workpiece, removing the need for pre-punching center holes and ensuring accurate placement every time. The heavy-duty fully ground body construction guarantees that the bit runs true, producing round, precise holes that meet tight tolerance requirements.

Chip evacuation is a critical factor in drilling performance, particularly in work-hardening materials like stainless steel. The Walter SST+ utilizes a "high flow" flute design that rapidly ejects chips from the hole. This prevents chip packing and reduces heat buildup, which is the primary cause of premature bit failure. Furthermore, the bit is treated with a special Bronze SST surface finish. This treatment acts as a lubricant, reducing friction between the bit and the workpiece, allowing for faster drilling speeds and smoother operation. Whether used in a stationary drill press or a portable hand drill, the Walter 01A526 delivers consistent, high-performance results.
