01B544 - Walter SST+ Cobalt Jobber Drill Bit - Wire Gauge #44

Premium Performance for Hard Metals

The Walter SST+ Jobber Drill Bit #44 (01B544) represents the pinnacle of drilling technology for industrial applications. Designed specifically to address the challenges of drilling through tough materials like stainless steel, this bit is engineered with a proprietary cobalt blend. This material composition provides exceptional hot hardness, allowing the bit to maintain its cutting edge even under the high temperatures generated during aggressive drilling operations. Unlike standard high-speed steel bits that dull quickly when facing work-hardening alloys, the SST+ series delivers consistent performance and extended tool life, making it a cost-effective choice for high-volume fabrication environments.

Advanced Geometry for Precision

Precision is paramount in professional machining and maintenance, and the Walter SST+ incorporates several geometric innovations to ensure accuracy. The bit features an exclusive Speed Tip design, which is self-centering. This eliminates the common issue of "walking" or wandering upon initial contact with the workpiece, thereby removing the need for pre-punching center holes. This feature alone significantly reduces setup time and improves overall workflow efficiency. Furthermore, the bit is constructed with a back-tapered body, a subtle design element that reduces the surface area in contact with the hole walls. This reduction in friction prevents binding and galling, which are common causes of bit breakage in deep-hole drilling.

Optimized Chip Evacuation

Effective chip removal is critical to preventing heat buildup, which is the primary enemy of drill bit longevity. The Walter 01B544 utilizes a unique "High Flow" flute design that rapidly evacuates swarf and chips from the cutting zone. Combined with the special bronze SST surface treatment, which acts as a lubricant to further reduce friction, this bit runs cooler and cuts faster than conventional alternatives. Whether utilized in a stationary drill press or a portable hand drill, the Walter SST+ #44 provides the reliability and speed required by MRO professionals and metalworkers demanding the best results in mild steel, non-ferrous metals, and particularly stainless steel.
