01K008 - Walter 1/8 Inch Cobalt Double-Ended Stub Drill Bit

Maximize Drilling Efficiency with Walter SST Double-End Stub Drills

In high-volume industrial environments, tool longevity and cycle time are critical metrics. The Walter 01K008 1/8" SST Double-End Stub Drill is engineered to address the specific challenges of drilling thin-gauge materials and sheet metal. Unlike standard jobber length bits that are prone to flexing and breakage when used with portable power tools, this stub-length drill provides superior rigidity. This structural integrity ensures that the energy from the drill motor is transferred directly into the cut, rather than being lost to deflection, resulting in cleaner holes and significantly reduced tool breakage.

The core of this high-performance tool is its material composition. Crafted from a specialized Cobalt High-Speed Steel (HSS) alloy, the bit offers exceptional heat resistance compared to standard black oxide alternatives. This is particularly important when drilling high-tensile materials or stainless steel, where heat buildup is the primary cause of cutting edge failure. To further enhance performance, Walter applies their proprietary SST surface treatment. This treatment increases surface lubricity, reducing friction at the cutting interface and facilitating smoother chip flow. The result is a drill bit that runs cooler and maintains its cutting edge for longer durations.

Productivity is further boosted by the intelligent geometry of the bit. The "High Flow" flute design is optimized to evacuate chips rapidly, preventing clogging that can lead to overheating and binding. Additionally, the self-centering point geometry eliminates the time-consuming step of center punching. Operators can place the bit directly on the workpiece and initiate the cut without the tool "walking" across the surface. Perhaps the most significant value proposition is the double-ended design. By providing two cutting ends on a single shaft, the 01K008 effectively doubles the lifespan of the consumable, reducing inventory requirements and lowering the cost per hole. For maintenance, repair, and operations (MRO) professionals seeking a reliable, cost-effective solution for sheet metal and thin-wall applications, this Walter drill bit is the superior choice.
