01A504 - Walter SST+ 1/16-Inch Cobalt Drill Bit for Stainless Steel

High-Performance Drilling for Tough Materials

The Walter 01A504 1/16" SST+ Drill Bit represents the pinnacle of drilling technology for industrial applications. Designed specifically to address the challenges of drilling through hard, high-tensile materials, this bit is engineered with a proprietary cobalt blend. This unique composition significantly enhances the bit's hardness and heat resistance, allowing it to maintain a sharp cutting edge even under the extreme temperatures generated when drilling stainless steel. Unlike standard high-speed steel bits that dull quickly on abrasive metals, the SST+ series is built to endure, providing a cost-effective solution for high-volume fabrication environments.

Efficiency is at the core of the SST+ design. The bit features a specialized "high flow" flute geometry that optimizes chip evacuation. By rapidly removing debris from the hole, the bit reduces friction and heat buildup—the primary causes of premature tool failure. This design allows operators to drill numerous holes in less time, boosting overall productivity. Furthermore, the exclusive bronze SST surface treatment acts as a lubricant and a shield, further reducing friction and adding an extra layer of toughness to the tool's body. Whether you are working in a machine shop or on a job site, this drill bit delivers consistent, reliable performance.

Precision is guaranteed with the 135° split point geometry. This self-centering tip eliminates the need for a center punch, preventing the bit from "walking" or skating across the surface of the workpiece. This is particularly advantageous when drilling on curved surfaces or round stock, ensuring that every hole is positioned exactly where intended. The heavy-duty construction of the Walter SST+ ensures that it can withstand the torque and pressure of both stationary drill presses and portable power tools, making it a versatile addition to any professional toolkit.
