01B531 - Walter SST+ Cobalt Jobber Drill Bit #31

High-Performance Industrial Drilling Solution

The Walter #31 SST+ Jobber Drill (SKU: 01B531) represents the pinnacle of drilling technology for industrial maintenance, repair, and operations (MRO). Designed to meet the rigorous demands of modern workshops, this drill bit is crafted from a specialized cobalt blend that provides superior hardness and heat resistance compared to standard high-speed steel bits. This material composition is critical when working with tough alloys, ensuring the bit retains its cutting edge longer, even under high-stress conditions.

Efficiency is at the core of the SST+ design. The bit features a revolutionary "High Flow" flute geometry that rapidly evacuates chips from the hole. This efficient chip removal prevents heat buildup—the primary cause of premature tool failure—and allows for faster drilling speeds. Coupled with a back-tapered body, the design significantly reduces friction and the risk of binding, making it a reliable choice for deep-hole drilling in solid materials.

Precision is paramount in professional settings, and the Walter SST+ delivers with its exclusive self-centering "Speed Tip." This feature eliminates the need for center punching or pilot holes, as the bit bites into the material immediately upon contact without "walking" or wandering across the surface. This is particularly advantageous when drilling on curved surfaces or round stock. Finished with a unique bronze SST surface treatment, this drill bit offers enhanced lubricity and durability, making it an essential tool for any industrial toolkit dealing with mild steel, stainless steel, and non-ferrous metals.
