01K007 - 7/64 Inch Cobalt Double-Ended Stub Drill Bit

Industrial Precision with Double the Lifespan

The Walter 01K007 7/64" SST Double-End Stub Drill is a premium cutting tool engineered for maintenance, repair, and operations (MRO) professionals who demand efficiency and durability. Manufactured from a specialized cobalt-blended High-Speed Steel (HSS) alloy, this drill bit offers exceptional hardness and heat resistance, far surpassing standard black oxide bits. Its defining feature is the double-ended design, which effectively provides two high-performance drill bits in a single unit. When one end eventually dulls after extensive use, the operator can simply flip the bit to access a fresh cutting edge, instantly doubling the tool's service life and reducing inventory costs.

Designed with a "stub" length profile, this bit provides superior rigidity compared to standard jobber-length drills. This shorter stature minimizes deflection and vibration, significantly reducing the risk of breakage even when applying heavy feed pressure. The proprietary SST surface treatment enhances lubricity, allowing for smoother drilling action and reduced heat generation. Coupled with a "High Flow" flute geometry, the tool evacuates chips rapidly, preventing clogging and ensuring a clean finish. The self-centering point geometry bites into the material immediately, eliminating the need for center punching and preventing the bit from "walking" across the workpiece. This level of precision makes it an indispensable tool for aerospace, automotive, and general industrial fabrication.
