01B542 - Walter SST+ #42 Cobalt Jobber Drill Bit for Stainless Steel

Industrial Grade Precision with Walter SST+ Drill Bits

The Walter 01B542 SST+ Jobber Drill Bit (#42) represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered by Walter Surface Technologies, this bit is meticulously crafted from a premium cobalt blend, designed specifically to withstand the high thermal stresses encountered when drilling through hard metals. Unlike standard bits that dull quickly under heat, the SST+ series maintains its cutting edge longer, ensuring consistent performance in production environments.

Efficiency is at the core of the SST+ design. The bit features a unique "High Flow" flute geometry coupled with a back-tapered body. This configuration significantly reduces friction and allows for rapid chip evacuation, preventing clogging and heat buildup that can compromise the structural integrity of the bit. The distinctive bronze SST surface treatment further enhances performance by acting as a lubricant barrier, smoothing the drilling action and extending the tool's lifespan.

For maintenance professionals, accuracy is non-negotiable. The Walter 01B542 is equipped with an exclusive self-centering "Speed Tip." This advanced point geometry bites into the material instantly, eliminating the common issue of "walking" or wandering across the workpiece. This feature allows for precise hole placement even on round or curved surfaces without the need for a center punch, saving valuable time on every job. Whether used in a stationary drill press or a portable hand drill, this #42 drill bit delivers reliable, high-speed results.
