01J019 - Walter #19 Cobalt Stub Drill Bit for Sheet Metal

Unmatched Rigidity with Walter SST Stub Drill Bits

When precision and durability are non-negotiable in your industrial operations, the Walter #19 SST Stub Drill stands out as a premier choice for metalworking professionals. Designed specifically to address the common challenges associated with drilling into thin gauge metals and hard alloys, this drill bit combines advanced materials with superior geometry. The "stub" design, characterized by a shorter overall length and flute length compared to standard jobber bits, provides exceptional rigidity. This structural integrity significantly reduces the likelihood of breakage, a frequent issue when applying pressure in tough drilling scenarios or when using portable hand drills where stability can be compromised.

The core of the Walter SST Stub Drill is its high-quality cobalt blend construction. Unlike standard high-speed steel (HSS) bits, the inclusion of cobalt allows this tool to withstand substantially higher temperatures, maintaining its cutting edge even when drilling through abrasive materials like stainless steel and other high-tensile alloys. This heat resistance translates directly to a longer service life, reducing the frequency of tool changes and downtime in your production line. Furthermore, the bit undergoes a specialized bronze SST surface treatment. This proprietary finish not only enhances the surface hardness but also promotes smoother chip evacuation and reduces friction, ensuring a cleaner cut and less heat buildup during the drilling process.

Efficiency is at the heart of the SST design. The bit features a self-centering split point geometry. This crucial feature eliminates the need for a center punch, as the bit bites into the material immediately upon contact without "walking" or wandering across the surface. This is particularly advantageous when working on curved surfaces or round stock, where precision starting is difficult. For maintenance, repair, and operations (MRO) environments, the ability to drill more holes in less time with a single bit offers a tangible return on investment. Whether you are drilling mild steel, non-ferrous metals, or demanding stainless steel sheets, the Walter #19 SST Stub Drill delivers consistent, high-performance results that professional machinists and fabricators trust.

In summary, the Walter 01J019 is not just a consumable; it is a solution for difficult drilling tasks. Its robust design minimizes flexing, ensuring that the energy from your drill is transferred directly into the cut. This makes it an ideal companion for both stationary drill presses and handheld power tools found in rigorous industrial settings.
