01D570 - Walter SST+ 7.00mm Cobalt Drill Bit for Stainless Steel

Industrial-Grade Precision and Durability

The Walter 01D570 7.00mm SST+ Drill Bit is engineered to meet the rigorous demands of modern industrial fabrication. In environments where efficiency and tool longevity are paramount, the SST+ series stands out as a premier solution. Constructed from a specialized cobalt blend, this drill bit offers superior hardness and heat resistance compared to standard high-speed steel bits. This metallurgical advantage allows it to maintain a sharp cutting edge even when subjected to the high temperatures generated during continuous drilling operations. For fabrication shops working with diverse materials, from mild steel to challenging stainless steel alloys, the 01D570 provides consistent, reliable performance that reduces downtime associated with frequent tool changes.

Advanced Geometry for Optimal Chip Evacuation

What truly sets the Walter SST+ apart is its thoughtful geometric design. The bit features a unique "high flow" flute configuration that is specifically optimized to evacuate chips rapidly from the hole. In materials like stainless steel, which are prone to work hardening if heat is allowed to build up, efficient chip removal is critical. By clearing debris quickly, the bit remains cooler, preventing the material from hardening and ensuring a clean, precise cut. Additionally, the body of the bit is back-tapered, a design choice that significantly reduces friction between the tool and the sidewalls of the hole. This reduction in friction not only lowers heat generation but also prevents the bit from binding, making it exceptionally effective for deep hole drilling.

Enhanced Surface Treatment

To further augment its performance, the 01D570 is finished with Walter's exclusive Bronze SST surface treatment. This coating acts as a high-performance lubricant, reducing resistance as the bit penetrates the material. It also provides a layer of protection against corrosion and wear. Whether utilized in a high-precision stationary drill press or a portable hand drill on the shop floor, the Walter 7.00mm SST+ Drill Bit delivers round, burr-free holes with minimal effort. It is the ideal choice for professionals who refuse to compromise on quality and demand tools that can keep pace with their production schedules.
