01B525 - Walter SST+ Cobalt Jobber Drill Bit, Wire Gauge #25

Premium Industrial Drilling Performance

The Walter 01B525 SST+ Jobber Drill Bit (Size #25) represents the pinnacle of industrial drilling technology, designed to meet the rigorous demands of maintenance, repair, and operations (MRO) professionals. In an industrial setting, efficiency is measured by the ability to perform repetitive tasks with precision and minimal downtime. This drill bit is engineered with a proprietary cobalt blend that provides exceptional hot hardness, allowing it to maintain a sharp cutting edge even when subjected to the high temperatures generated during aggressive drilling in tough alloys.

One of the standout features of the SST+ series is the exclusive "Speed Tip." This 135-degree split point geometry is self-centering, which eliminates the need for pre-punching or pilot holes. For facility managers and machinists, this means faster cycle times and reduced labor costs. The bit also features a unique "High Flow" flute design. Unlike standard bits that may clog with swarf, the SST+ efficiently evacuates chips from the hole, reducing heat buildup and preventing the work-hardening of sensitive materials like stainless steel. The bronze SST surface treatment further enhances performance by acting as a lubricant, reducing friction and extending the tool's life significantly compared to standard high-speed steel bits.

The #25 wire gauge size (0.1495 inches) is a critical dimension for specific tapping and clearance applications in assembly work. Whether you are drilling through mild steel structural components or precision stainless steel parts, the Walter 01B525 delivers consistent, round holes with minimal burr formation. Its back-tapered body design is a subtle but crucial engineering detail that prevents the bit from binding in deep holes, ensuring that your equipment and your workpiece remain undamaged. Invest in Walter SST+ bits to experience a tangible improvement in your workshop's productivity.
