OVERVIEW

Industrial Grade Precision and Durability

The Walter 15/64" SST Double-End Stub Drill is engineered to meet the rigorous demands of industrial maintenance, repair, and operations. Designed with a state-of-the-art cobalt high-speed steel (HSS) blend, this tool offers exceptional resistance to heat and wear, significantly outperforming standard black oxide alternatives. The inclusion of cobalt in the alloy matrix allows the bit to maintain its hardness at higher temperatures, making it an excellent choice for drilling through tough metals, including stainless steel and other hard alloys found in aeronautical and automotive environments.

Efficiency is at the core of the SST+ geometry. The "High flow" flute design is specifically optimized to evacuate chips rapidly, preventing heat buildup and ensuring consistent cutting performance. This feature is critical when drilling multiple holes in succession, as it maintains the integrity of both the tool and the workpiece. Furthermore, the specialized SST surface treatment enhances lubricity, reducing friction during the drilling process and contributing to a smoother finish with minimal burrs.

The double-ended stub configuration is a key value proposition for facility managers and machinists. By providing two cutting points on a single shaft, users effectively get two tools in one, reducing inventory costs and downtime associated with tool changes. The stub length adds a layer of structural rigidity that standard jobber length bits lack, making this bit highly resistant to snapping under side-load pressure or when drilling into curved surfaces.

Technical Specifications

This drill bit features a precise 15/64" diameter and a self-centering point that bites into the material immediately upon contact. This eliminates the need for pre-punching, streamlining the workflow in high-volume drilling operations. Whether used in portable drills or stationary machinery, the Walter SST Double-End Stub Drill delivers reliable, high-performance results for the most challenging industrial applications.

FAQ

Stub drill bits are shorter than standard bits, which makes them much more rigid. This rigidity prevents the bit from flexing or breaking, especially when drilling into hard materials or applying side pressure.

The double-ended design provides two cutting points on a single tool. When one end becomes dull, you can simply flip the bit around and use the other end, effectively doubling the life of the product.

Yes, the Walter SST drill bit is made from a Cobalt HSS alloy, which provides the high heat resistance and hardness necessary for drilling through tough metals like stainless steel.

No, this bit features a unique self-centering point that prevents 'walking' on the material surface, allowing you to start drilling accurately without a center punch.

SST is a specialized surface treatment applied to the bit that increases lubricity. This helps reduce friction and heat buildup during drilling, extending the tool's life.

Yes, it is suitable for all types of metals, including aluminum. The high-flow flute design helps clear soft aluminum chips quickly to prevent clogging.

This specific drill bit has a diameter of 15/64 inches.

Yes, the Cobalt blend and SST geometry offer significantly longer lifespan and better performance than standard black oxide bits, especially in demanding applications.
