01B505 - Walter SST+ Heavy Duty Cobalt Drill Bit, #5 Wire Gauge

Industrial Grade Precision with Walter SST+ Drill Bits

The Walter 01B505 #5 SST+ Jobber Drill Bit is engineered for the most demanding industrial maintenance and fabrication environments. Manufactured by Walter Surface Technologies, this bit represents the pinnacle of drilling performance, specifically designed to tackle tough materials that often cause standard high-speed steel bits to fail. The core of the SST+ performance lies in its premium cobalt blend construction. This material composition provides exceptional heat resistance, allowing the bit to maintain its cutting edge hardness even at the high temperatures generated when drilling through stainless steel and other hard alloys.

Efficiency in MRO operations is driven by tool life and speed. The SST+ series features a unique "high flow" flute design that rapidly evacuates chips from the hole. This efficient chip removal is critical for preventing heat buildup, which is the primary cause of premature drill bit failure. Additionally, the bit undergoes a specialized bronze SST surface treatment. This treatment not only enhances the surface hardness but also significantly reduces friction between the bit and the workpiece, further extending the tool's service life. The back-tapered body geometry is another advanced feature, designed to reduce surface contact and prevent binding, ensuring smooth operation even in deep-hole applications.

For procurement specialists and shop managers, the Walter SST+ offers a high return on investment by reducing downtime associated with bit changes and minimizing the number of bits consumed per project. Its versatility across mild steel, non-ferrous metals, and stainless steel makes it a universal solution for diverse workshop needs. The #5 wire gauge size (0.2055 inches) is manufactured to precise tolerances, ensuring accurate hole sizing for tapping or clearance applications.
