01B545 - Walter SST+ Cobalt Jobber Drill Bit #45 (0.0820")

High-Performance Drilling with Walter SST+ Technology

The Walter 01B545 SST+ Jobber Drill Bit (#45) represents the pinnacle of drilling technology for industrial maintenance and fabrication. Designed by Walter Surface Technologies, this bit is engineered to overcome the common challenges associated with drilling hard metals, particularly stainless steel. The core of its performance lies in its material composition; crafted from a specialized cobalt blend, the SST+ bit withstands higher temperatures than standard high-speed steel bits. This thermal resilience is critical when drilling work-hardening materials, ensuring the cutting edge remains sharp longer and reducing the frequency of bit changes in high-volume environments.

Precision is paramount in MRO applications, and the SST+ delivers with its exclusive self-centering "Speed Tip." This feature allows operators to drill exact holes without the preliminary step of center punching, effectively preventing the bit from "walking" or wandering across the workpiece surface. This not only saves time but also protects the surface finish of the material. Furthermore, the bit features a unique "High flow" flute design. This geometry is optimized to evacuate chips rapidly from the hole, preventing heat buildup and clogging that can lead to bit failure. The back-tapered body further assists in this by reducing friction along the sidewalls, minimizing the risk of binding even in deep-hole applications.

To further enhance longevity, Walter applies a proprietary bronze SST surface treatment. This coating acts as a lubricant and heat shield, significantly reducing friction during the cut. Whether utilized in a stationary drill press for precision components or a portable hand drill for on-site repairs, the Walter #45 SST+ Jobber Drill provides consistent, reliable performance. It is the ideal choice for professionals requiring efficiency and durability when working with mild steel, non-ferrous metals, and difficult-to-machine stainless steel alloys.
