01A030 - Walter SST+ 15/32" Cobalt Jobber Drill Bit with Quick Shank

High-Performance Drilling with Walter SST+ Technology

The Walter 01A030 15/32" SST+ Jobber Drill Bit represents the pinnacle of drilling efficiency for industrial maintenance and fabrication. Engineered with a proprietary cobalt blend, this tool is designed to withstand the high temperatures generated during aggressive drilling operations in tough materials like mild steel, stainless steel, and aluminum. Unlike standard high-speed steel bits that may dull quickly under thermal stress, the SST+ maintains its cutting edge longer, ensuring consistent performance and reduced downtime for tool changes.

One of the standout features of this drill bit is the exclusive Quick Shank design. In high-torque applications, round shanks often spin inside the chuck, damaging both the bit and the drill. The Quick Shank features engineered flats that lock securely into both keyed and keyless chucks, ensuring 100% power transmission from the motor to the workpiece. This is particularly beneficial for MRO professionals using cordless power tools, as the efficient energy transfer allows for more holes to be drilled per battery charge, maximizing daily productivity.

Precision is paramount in metalworking, and the Walter SST+ delivers with its self-centering Speed Tip. This advanced geometry prevents the bit from "walking" or wandering across the surface of the material, eliminating the need for pre-punching or pilot holes. Combined with a heavy-duty fully ground body and a back-tapered design to reduce friction, this bit drills round surfaces and thin gauge metals with remarkable ease. The special bronze SST surface treatment further aids in chip evacuation and heat dissipation, making the 01A030 an essential component of any professional tool crib.

Technical Specifications and Applications

Designed for versatility, the Walter 01A030 excels in a wide range of materials including non-ferrous metals and thin gauge sheets. Its robust construction allows it to drill through multiple layers of metal effortlessly. Whether utilized in a stationary drill press or a portable hand drill, the SST+ Jobber bit provides the reliability required for critical assembly and repair tasks. The 15/32" diameter is a common size for bolt clearance holes and tapping preparation, making this specific SKU a high-demand item for machine shops and field service technicians alike.
