OVERVIEW

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.

FAQ

Stub length drill bits are shorter than standard jobber bits, providing increased rigidity and strength. This reduces the likelihood of the bit flexing or breaking, especially when drilling into hard materials or applying significant pressure.

Yes, the Walter SST drill bit is made from a cobalt HSS blend, which provides the heat resistance and hardness necessary to effectively drill through stainless steel and other hard alloys.

Double-ended means the drill bit has cutting tips on both ends of the shaft. When one side becomes dull, you can flip the bit around and use the other side, effectively giving you two bits in one.

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

SST is a proprietary surface treatment by Walter that improves the lubricity of the drill bit. This reduces friction during drilling, keeps the bit cooler, and extends the tool's life.

Absolutely. The 7/64" size and rigid stub design make it ideal for drilling out rivets in automotive and sheet metal applications without damaging the surrounding material.

It is designed for all types of metals, including mild steel, stainless steel, aluminum, and other non-ferrous metals.

The High Flow flute design is engineered to evacuate chips from the hole quickly. This prevents the flutes from clogging, reduces heat buildup, and allows for faster drilling speeds.
