01B551 - Walter SST+ Cobalt Jobber Drill Bit - Wire Gauge #51

High-Performance Cobalt Drilling Solution

The Walter SST+ Jobber Drill Bit (SKU: 01B551) represents the pinnacle of drilling technology for industrial maintenance and repair operations. Sized at Wire Gauge #51, this bit is engineered to tackle the toughest materials found in modern manufacturing environments, including stainless steel, mild steel, and non-ferrous metals. Unlike standard high-speed steel bits that dull quickly under thermal stress, the SST+ series utilizes a proprietary cobalt blend that maintains hardness even at high drilling temperatures.

Efficiency is critical in MRO settings, and the SST+ delivers with its exclusive "Speed Tip" design. This 135-degree split point is self-centering, allowing operators to drill immediately without the time-consuming step of center punching. This feature is particularly valuable when working on rounded surfaces or in awkward positions where tool stability is a challenge. The bit's body features a back-tapered geometry and a "High Flow" flute design, which work in tandem to evacuate chips rapidly. This prevents clogging and heat buildup, two primary causes of premature tool failure.

Durability is further enhanced by Walter's special bronze SST surface treatment. This coating not only protects the bit from environmental factors but also adds a layer of lubricity that reduces friction during the cut. For professionals requiring precision holes with a diameter of 0.0670 inches, the Walter #51 SST+ drill bit provides a reliable, long-lasting solution that minimizes downtime and maximizes productivity.
