01B511 - Walter SST+ Cobalt Jobber Drill Bit #11

High-Performance Drilling with Walter SST+ Technology

The Walter SST+ Jobber Drill Bit #11 (SKU: 01B511) represents the pinnacle of drilling efficiency for industrial maintenance and fabrication. Designed to tackle the toughest materials, this drill bit is crafted from a proprietary cobalt blend that significantly outperforms standard high-speed steel (HSS) bits. The inclusion of cobalt provides exceptional heat resistance, allowing the bit to maintain its cutting edge even when drilling through work-hardening materials like stainless steel. This makes the SST+ series an essential tool for professionals who demand reliability and longevity in their consumables.

One of the standout features of this drill bit is the exclusive "Speed Tip." This self-centering point geometry allows the operator to drill immediately upon contact with the workpiece, completely eliminating the need for center punching or pilot holes. This feature is particularly beneficial when working on round surfaces, such as pipes or tubing, where standard bits tend to "walk" or wander. The precision of the Speed Tip ensures accurate hole placement every time, reducing scrap and rework costs.

In addition to its cutting geometry, the Walter SST+ #11 features a sophisticated "High Flow" flute design. This innovation optimizes the evacuation of chips from the hole, preventing clogging and reducing the friction that leads to heat buildup. Coupled with the unique bronze SST surface treatment, the bit operates cooler and smoother, extending its service life. The back-tapered body design further reduces surface contact with the hole walls, minimizing drag and maximizing the energy transfer to the cutting edge. Whether used in a portable hand drill or a stationary drill press, the Walter SST+ delivers consistent, high-speed performance across mild steel, non-ferrous metals, and stainless steel applications.
