01A528 - Walter SST+ 7/16" Cobalt Drill Bit for Stainless Steel

High-Performance Drilling for Industrial Applications

The Walter 01A528 7/16" SST+ Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Designed to address the common challenges of drilling through hard alloys, this bit features a proprietary cobalt blend that significantly increases heat resistance and wear life. In high-production environments where downtime for tool changes equates to lost revenue, the durability of the SST+ line provides a tangible return on investment.

One of the standout features of this drill bit is its exclusive "High Flow" flute design. This geometry is engineered to evacuate chips rapidly, preventing clogging and heat accumulation that typically leads to bit failure. The heavy-duty, fully ground body ensures that the bit maintains its structural integrity even under substantial torque, providing straight, accurate holes every time. Furthermore, the special bronze SST surface treatment acts as a lubricant, reducing friction at the cutting edge and further extending the tool's operational life.

Versatility is key in MRO operations, and the Walter SST+ excels across a wide range of materials. While it is specifically optimized for the rigors of stainless steel, it performs exceptionally well on mild steel and non-ferrous metals. Its self-centering capability is particularly beneficial when drilling on curved surfaces, such as pipes or tubing, eliminating the need for center punching in many scenarios. For professionals demanding precision and longevity, the Walter SST+ is the superior choice.
