OVERVIEW

Maximize Productivity with Walter SST Double-Ended Stub Drills

The Walter SST Double-Ended Stub Drill (SKU: 01K151) represents a significant leap forward in drilling efficiency for industrial professionals. Designed specifically to address the challenges of drilling through thin materials, this tool combines advanced metallurgy with a practical, cost-saving geometry. At the core of its performance is a state-of-the-art cobalt blend. Unlike standard high-speed steel or black oxide bits that dull quickly under the heat of friction, this cobalt formulation maintains its hardness at higher temperatures, ensuring a sharp cutting edge for significantly longer periods.

The defining feature of this product is its double-ended design. In high-paced production environments or automotive repair shops, time spent changing dull bits adds up. With the Walter SST, when one side eventually dulls, the user can simply flip the bit around and continue working immediately with a fresh point. This effectively doubles the lifespan of a single unit compared to traditional single-ended stub drills. Furthermore, the "stub" length—shorter than jobber length bits—provides superior rigidity. This increased stiffness virtually eliminates the flexing and snapping often associated with drilling hard or thin metals, making it a reliable choice for precision work.

Applications for the 01K151 are vast, ranging from HVAC ductwork and electrical enclosures to specialized aeronautical repairs. The bit is engineered to penetrate sheet metal cleanly without creating excessive burrs or deforming the material. Its self-centering capabilities are particularly beneficial when working on curved automotive panels, preventing the bit from "walking" and damaging the finish. For maintenance, repair, and operations (MRO) professionals seeking to reduce consumable costs while maintaining high standards of work, the Walter SST Double-Ended Stub Drill is an indispensable asset.

Key Benefits:

  • Extended Tool Life: The cobalt blend resists heat buildup, outlasting conventional black oxide bits.
  • Cost Efficiency: Two drill points in one tool reduce inventory needs and replacement frequency.
  • Precision & Safety: Short flute length minimizes breakage and improves control on thin gauge metals.

FAQ

The primary advantage is longevity and convenience. A double-ended bit has a cutting point on both ends, so when one side becomes dull, you can simply flip the bit around and use the other side, effectively getting two drill bits in one.

This drill bit is engineered with a cobalt blend, making it suitable for drilling through sheet metal, thin steel, aluminum, and other materials commonly found in automotive and aeronautical applications.

Stub length refers to a shorter overall length compared to standard 'jobber' bits. This shorter length provides greater rigidity, reducing the chance of the bit flexing or breaking, which is especially important when drilling thin or hard materials.

Yes, the Walter SST is made from a cobalt blend which offers superior heat resistance and durability compared to standard black oxide bits, resulting in a significantly longer lifespan.

Absolutely. The stub length and double-ended design make it ideal for automotive applications, such as drilling out spot welds or creating holes for rivets in body panels.

While a center punch is always recommended for precision, the rigid stub design helps minimize 'walking' on the material surface compared to longer, more flexible drill bits.

SST typically refers to the Super Speed Tooling or similar high-performance designation by Walter, indicating the use of premium cobalt-blended high-speed steel for demanding applications.

You should flip the bit when you notice a significant decrease in cutting speed or if the bit requires excessive pressure to penetrate the material. The second side will provide a fresh, sharp cutting edge.
