01A519 - Walter SST+ 19/64" Cobalt Blend Drill Bit

High-Performance Drilling with Walter SST+ Technology

The Walter 01A519 19/64" SST+ Drill Bit represents the pinnacle of industrial drilling technology, designed to meet the rigorous demands of modern fabrication and maintenance environments. At the core of this tool is a sophisticated cobalt blend that significantly enhances the hardness and heat resistance of the bit. This material composition is critical when working with tough substrates such as stainless steel, where excessive heat generation can rapidly degrade standard high-speed steel bits. By maintaining its cutting edge at higher temperatures, the SST+ ensures consistent performance and a longer service life, reducing the frequency of tool changes and downtime.

Beyond its metallurgy, the Walter SST+ features a heavy-duty, fully ground body that provides exceptional structural integrity. This robust construction minimizes deflection during operation, ensuring that every hole is drilled with precision and accuracy. The geometry of the bit includes a "High flow" flute design, which is engineered to evacuate chips rapidly from the cutting zone. Efficient chip removal is vital for preventing heat buildup and clogging, particularly in deep-hole applications. This design feature allows operators to drill faster and with less feed pressure, improving overall productivity.

To further optimize performance, Walter has applied a special bronze SST surface treatment to the bit. This coating acts as a lubricant, reducing friction between the tool and the workpiece. The result is a smoother drilling action and a cleaner finish on the hole walls. Whether utilized in a portable hand drill for on-site repairs or a stationary drill press for production runs, the Walter 01A519 delivers reliable, high-speed results across a variety of materials, including mild steel, non-ferrous metals, and challenging stainless steel alloys.
