01D580 - Walter SST+ 8.00mm Cobalt Drill Bit for Stainless Steel

High-Performance Metallurgy for Industrial Drilling

The Walter 01D580 8.00mm SST+ Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered to address the common challenges of drilling tough alloys, this bit features a proprietary cobalt blend that significantly enhances the hardness and heat resistance of the substrate. This metallurgical advantage allows the SST+ to maintain its cutting edge even under the high thermal loads generated when drilling stainless steel and other high-tensile materials.

Beyond the core material, Walter has applied their exclusive Bronze SST surface treatment. This specialized coating serves a dual purpose: it drastically reduces the coefficient of friction between the bit and the workpiece, and it facilitates smoother chip flow. The result is a drilling process that generates less heat, preventing work-hardening of the material—a critical factor when working with austenitic stainless steels.

The geometric design of the SST+ is equally advanced. It incorporates a back-tapered body which provides clearance behind the cutting edges, eliminating binding and reducing drag. The high-flow flute design ensures that chips are evacuated rapidly, preventing clogging and breakage. Whether utilized in a stationary drill press or a portable hand drill, the self-centering point geometry bites instantly, even on round surfaces like piping or tubing, ensuring precision without the need for a center punch.
