01A030A - Walter SST 15/32" Cobalt Drill Bit with Quick Shank

High-Performance Drilling with Walter SST Technology

The Walter 01A030A 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 thermal stresses associated with drilling through mild steel, aluminum, and thin gauge metals. Unlike standard high-speed steel bits, the SST series maintains its cutting edge longer, reducing downtime for tool changes and sharpening. The heavy-duty fully ground construction ensures that every hole is precise, round, and burr-free, meeting the rigorous standards of professional workshops.

Innovative Quick Shank Design

One of the standout features of this drill bit is the exclusive Quick Shank. In high-torque applications, round shanks often slip 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 cutting edge. This feature is particularly beneficial for users of cordless power tools, as it eliminates energy waste caused by slippage, thereby allowing operators to drill more holes per battery charge. This efficiency makes the SST line a preferred choice for mobile repair operations and field installations.

Precision and Ease of Use

Accuracy is paramount in metalworking, and the Walter SST bit delivers with its self-centering Speed Tip. This advanced tip geometry bites into the material instantly, eliminating the need for pre-punching or pilot holes. It effectively prevents the bit from "walking" or wandering across the surface, which is a common issue when drilling into curved surfaces like pipes or round stock. Additionally, the back-tapered body design reduces friction along the flutes, preventing binding and ensuring smooth chip evacuation. Finished with a special bronze SST surface treatment, this bit runs cooler and cuts faster, making it an essential tool for any serious machinist or technician.
