01B533 - Walter SST+ Cobalt Drill Bit #33 Wire Gauge

Precision Drilling with Walter SST+ Technology

The Walter 01B533 SST+ Jobber Drill Bit (Size #33) represents the pinnacle of drilling performance for industrial maintenance and fabrication. Designed to tackle the toughest materials, this bit is engineered from a premium cobalt blend that significantly outperforms standard high-speed steel (HSS) bits. The inclusion of cobalt provides exceptional heat resistance, allowing the bit to maintain its cutting edge even when drilling through work-hardening alloys like stainless steel.

One of the standout features of the SST+ series is the exclusive "Speed Tip". This 135° split point design is self-centering, eliminating the need for a center punch and preventing the bit from "walking" across the workpiece surface. This ensures immediate engagement with the material and precise hole placement every time. Combined with a robust web construction, the 01B533 delivers accurate, round holes with minimal burr formation.

Efficiency is further enhanced by Walter's innovative high-flow flute design. The wide flutes rapidly evacuate chips from the hole, preventing clogging and reducing heat buildup—the primary cause of drill bit failure. Additionally, the back-tapered body reduces friction along the sides of the hole, minimizing the risk of binding or snapping the bit during deep drilling operations. Finished with a bronze SST surface treatment, this drill bit offers reduced friction and extended tool life, making it an essential tool for professionals requiring reliability and precision.
