01A015 - Walter SST+ 15/64" Cobalt Blend Jobber Drill Bit with Quick Shank

High-Performance 15/64" Cobalt Blend Drill Bit

The Walter 01A015 SST Jobber Drill Bit is an industrial-grade cutting tool engineered for precision and efficiency in metalworking applications. Featuring a diameter of 15/64 inches, this bit is constructed from a premium cobalt blend, which offers superior hardness and heat resistance compared to standard high-speed steel. This material composition allows the bit to maintain its cutting edge longer, even under high-temperature drilling conditions often encountered in industrial environments.

A defining feature of this model is the exclusive Quick Shank technology. This shank design is specifically engineered to provide a secure, positive lock in both keyed and keyless chucks, effectively eliminating the frustration of bit slippage during high-torque operations. This feature is particularly beneficial when using cordless power tools, as it ensures efficient energy transfer from the tool to the workpiece. The bit also incorporates a self-centering "Speed Tip" geometry that prevents walking on the material surface, allowing for precise hole placement without the prerequisite of center punching.

The body of the drill bit is fully ground and features a back-tapered design. This geometry reduces surface contact friction between the bit and the hole wall, thereby minimizing heat generation and preventing binding. The bronze SST surface treatment further enhances performance by adding a layer of lubricity and corrosion resistance. Designed to maximize productivity, the 01A015 enables operators to drill more holes per battery charge, making it an economically efficient choice for high-volume fabrication tasks involving mild steel, aluminum, and thin gauge metals.
