01A530 - Walter 15/32" SST+ Cobalt Blend Jobber Drill Bit

High-Performance Drilling with Walter SST+ Technology

The Walter 01A530 15/32" SST+ Drill Bit is a premier cutting tool engineered for industrial environments where precision, speed, and durability are paramount. Manufactured by Walter Surface Technologies, the SST+ series is renowned for its ability to tackle the toughest materials, including stainless steel, heavy-duty alloys, and mild steel, without compromising on performance. This specific bit features a diameter of 15/32 inches, making it a versatile addition to any machinist's or fabricator's toolkit.

At the core of the SST+ drill bit's performance is its material composition. It is crafted from a specialized cobalt blend that provides exceptional heat resistance. In high-speed drilling applications, friction generates intense heat that can rapidly dull standard high-speed steel (HSS) bits. The cobalt content in the SST+ allows the bit to maintain its hardness and cutting edge even at elevated temperatures, significantly extending the tool's service life. This makes it an ideal choice for repetitive drilling tasks in hard metals where tool longevity directly impacts operational efficiency.

The geometry of the 01A530 is designed for accuracy and ease of use. It features a 135-degree split point, a self-centering design that bites into the material immediately upon contact. This eliminates the common issue of "walking" or wandering across the workpiece, thereby removing the need for pre-punching or pilot holes. This feature alone saves valuable time during fabrication and assembly processes. Furthermore, the heavy-duty fully ground body construction ensures the bit remains rigid under torque, producing rounder, more precise holes.

Another distinguishing feature is the exclusive Bronze SST surface treatment. This specialized coating serves multiple purposes: it acts as a lubricant to reduce friction between the bit and the workpiece, it facilitates smoother chip flow, and it helps dissipate heat. Combined with a unique flute design that promotes rapid chip evacuation, the Walter SST+ drill bit prevents clogging and binding, ensuring a smooth drilling action from start to finish. Whether utilized in a stationary drill press or a portable hand drill, the 01A530 delivers consistent, professional results.
