OVERVIEW

Industrial-Grade Precision with Walter SST Double-Ended Drills

The Walter 01K013 13/64" SST Double-End Stub Drill represents the pinnacle of drilling efficiency for industrial maintenance and fabrication environments. Engineered by Walter Surface Technologies, this tool is designed to address the common failure points of standard length drill bits when working with thin gauge materials. The "stub" length profile provides exceptional rigidity, virtually eliminating the flexing and snapping that often occurs with jobber-length bits in high-torque or off-angle drilling scenarios. This rigidity is crucial for maintaining hole tolerance and roundness in sheet metal applications.

At the core of this bit's performance is its advanced metallurgy. Manufactured from a premium Cobalt blend High-Speed Steel (HSS), the 01K013 offers significantly higher hot hardness than conventional black oxide or standard HSS bits. This allows the bit to maintain a sharp cutting edge even under the high thermal loads generated when drilling stainless steel and other tough alloys. The tool is further enhanced by Walter's proprietary SST surface treatment, which utilizes a bronze-colored oxide coating to increase surface lubricity. This reduction in friction facilitates smoother chip flow and lowers the overall cutting temperature, extending the tool's service life.

Efficiency is maximized through the double-ended design. By providing two fully ground cutting heads on a single shaft, operators effectively receive two tools in one. When one end dulls, simply flip the bit in the chuck to continue working, reducing trips to the tool crib and minimizing downtime. The 135° self-centering split point geometry ensures immediate engagement with the workpiece, preventing the bit from "walking" across the surface and removing the necessity for pre-punching operations. For MRO professionals seeking reliability and cost-effectiveness, the Walter SST Double-End Stub Drill is the superior choice.

FAQ

A double-ended drill bit features cutting heads on both ends of the shaft. This effectively gives you two drill bits in one tool; when one side becomes dull, you can simply flip it over and use the other side, doubling the tool's lifespan.

It is called a stub drill because it has a shorter overall length compared to standard 'jobber' bits. This shorter length provides increased rigidity and strength, making it less likely to break when drilling hard materials or thin sheet metal.

Yes, the Walter 01K013 is made from a Cobalt blend HSS which is specifically designed to withstand the high heat generated when drilling tough metals like stainless steel.

No, this bit features a 135° self-centering split point geometry that bites into the material immediately, preventing the bit from walking or skating across the surface.

SST stands for Super Surface Treatment. It is a proprietary coating by Walter that increases lubricity on the bit's surface, reducing friction and heat buildup to extend the life of the cutting edge.

Absolutely. The stub length makes it very stable and easy to control, which is ideal for portable hand drilling applications where long bits might wobble or snap.

The diameter is 13/64 of an inch.
