01A508 - Walter SST+ 1/8 Inch Cobalt Drill Bit for Stainless Steel

Premium Industrial Drilling Performance

The Walter 01A508 1/8" SST+ Drill Bit is engineered to meet the rigorous demands of modern industrial fabrication and maintenance operations. Designed with a proprietary cobalt alloy blend, this tool offers exceptional red hardness, allowing it to maintain its cutting edge even under the extreme temperatures generated when drilling high-tensile materials. Unlike standard high-speed steel bits that soften and dull rapidly, the SST+ composition ensures extended tool life and consistent performance in repetitive drilling applications.

A key feature of the 01A508 is its exclusive "High Flow" flute design. This geometry is specifically calculated to accelerate chip evacuation, preventing the clogging and heat accumulation that often lead to premature tool failure. By efficiently clearing debris from the hole, the bit maintains a cooler operating temperature and reduces the torque load on the drilling machine. This is complemented by a fully ground body construction, which guarantees superior concentricity compared to rolled bits, resulting in more precise hole sizing and reduced vibration during operation.

The surface of the bit is treated with a specialized Bronze SST coating. This treatment acts as a lubricant and heat barrier, significantly reducing the coefficient of friction between the tool and the workpiece. This is particularly advantageous when working with materials that tend to work-harden, such as stainless steel series 300 and 400. The combination of the heavy-duty web, the split point geometry for self-centering action, and the advanced metallurgical composition makes the Walter SST+ 1/8" bit an indispensable asset for professionals requiring reliability and efficiency in their tooling inventory.

Whether utilized in stationary drill presses or portable hand drills, the 01A508 delivers aggressive penetration rates and durability. It is rated for a wide spectrum of materials, including mild steel, non-ferrous metals, and particularly tough stainless steel alloys, making it a versatile solution for complex MRO environments.
