01D530 - Walter SST+ 3.00mm Cobalt Drill Bit for Stainless Steel

Premium 3.00mm Cobalt Drill Bit for Industrial Applications

The Walter 01D530 3.00mm SST+ Drill Bit is an industrial-grade cutting tool designed to meet the rigorous demands of modern manufacturing and maintenance environments. Crafted from a high-performance cobalt blend, this drill bit is engineered to penetrate the toughest materials, including stainless steel, mild steel, and various non-ferrous alloys. The inclusion of cobalt in the substrate significantly increases the bit's red hardness, allowing it to maintain a sharp cutting edge even under the high thermal loads generated when drilling hard metals. This makes it an indispensable tool for machine shops and fabrication facilities where efficiency and tool longevity are paramount.

A standout feature of the SST+ series is the proprietary "High Flow" flute design. This geometry is optimized to evacuate chips rapidly from the hole, preventing chip packing and heat buildup that can lead to premature tool failure. Coupled with a back-tapered body, the 01D530 minimizes friction along the sidewalls, ensuring smooth operation and reducing the torque load on your drilling equipment. The bit is finished with a specialized Bronze SST surface treatment, which further enhances lubricity and wear resistance. Whether used in a stationary drill press or a portable hand drill, this Walter drill bit delivers consistent, precise holes with reduced cycle times, making it a cost-effective solution for high-volume drilling operations.
