01D520 - Walter SST+ 2.00mm Cobalt Drill Bit for Stainless Steel

High-Performance Industrial Drilling

The Walter SST+ 2.00mm Drill Bit (01D520) represents the pinnacle of drilling technology for industrial maintenance and fabrication. Designed to tackle the most demanding materials, this drill bit is engineered with a proprietary cobalt blend that significantly enhances hardness and heat resistance compared to standard high-speed steel. This composition makes it an ideal choice for continuous drilling operations in stainless steel, mild steel, and non-ferrous metals found in heavy manufacturing environments.

Efficiency is at the core of the SST+ design. The bit features an exclusive "High Flow" flute geometry that rapidly evacuates chips from the hole, preventing clogging and heat accumulation that typically degrades tool life. Coupled with a specialized back-tapered body, this design minimizes friction along the sidewalls, allowing the bit to penetrate deep materials without binding. For MRO professionals, this means less downtime changing dull bits and more consistent performance across every job.

The surface is finished with a unique Bronze SST treatment, which acts as a lubricant to further reduce friction and drilling temperature. Whether used in stationary drill presses or portable hand drills, the Walter 01D520 delivers precise, clean holes with minimal effort. Its ability to bite into round surfaces without walking ensures accuracy even in difficult setups.
