01B530 - Walter SST+ Cobalt Drill Bit #30 Wire Gauge

Premium Performance for Industrial Drilling

The Walter 01B530 SST+ Jobber Drill Bit (#30) represents the pinnacle of drilling technology for industrial maintenance, repair, and operations (MRO). Designed by Walter Surface Technologies, this bit is engineered to solve the common frustrations associated with drilling hard metals. At its core is a premium cobalt blend (M35) substrate, which provides significantly higher heat resistance than standard high-speed steel. This allows the SST+ to maintain its cutting edge even under the extreme temperatures generated when drilling stainless steel and other tough alloys.

Efficiency in a production environment is measured by speed and accuracy. The SST+ features a 135° split point "Speed Tip" that is self-centering. This geometry eliminates the need for pre-punching or pilot holes, as the bit bites into the material immediately upon contact without "walking" across the surface. This feature alone saves valuable time on every hole drilled. Furthermore, the exclusive "High Flow" flute design is engineered to evacuate chips rapidly. Efficient chip removal is critical to preventing heat buildup—the primary cause of premature bit failure. By keeping the cutting zone cooler, the tool life is extended, reducing the frequency of bit changes and lowering overall consumable costs.

The body of the drill bit features a back taper, a subtle but crucial design element that reduces surface contact between the bit and the hole walls. This reduction in friction prevents binding, which is particularly beneficial when drilling deep holes or using portable drills where alignment may vary. Finished with a bronze SST surface treatment, this #30 wire gauge bit is the reliable choice for professionals who demand precision and durability in their tooling.
