01D625 - Walter SST+ 12.50mm Cobalt Blend Heavy-Duty Drill Bit

High-Performance Drilling with Walter SST+ Technology

The Walter 01D625 12.50mm SST+ Drill Bit represents the pinnacle of drilling performance for industrial applications. Designed to tackle the toughest materials found in maintenance, repair, and fabrication environments, this bit is engineered with a proprietary cobalt blend. This material composition provides exceptional heat resistance, allowing the bit to maintain its cutting edge even when drilling through work-hardening materials like stainless steel. Unlike standard high-speed steel bits that dull quickly under thermal stress, the SST+ series is built to endure, delivering more holes per bit and reducing overall tooling costs.

Advanced Geometry for Speed and Precision

Speed and accuracy are critical in professional settings, and the Walter SST+ delivers on both fronts. The drill bit features a unique "high flow" flute design that rapidly evacuates chips from the hole. Efficient chip removal is vital for preventing heat buildup and binding, especially in deep drilling applications. Complementing the flute design is a back-tapered body, which significantly reduces friction along the sidewalls of the hole. This geometric advantage allows for smoother drilling action and less strain on your power tools, whether you are using a stationary drill press or a portable hand drill.

Durable Bronze SST Surface Treatment

To further enhance performance, Walter applies a special bronze SST surface treatment to the 01D625. This coating acts as a lubricant, reducing friction at the cutting interface and protecting the bit from corrosion. The result is a tool that cuts cooler and lasts longer. Whether you are drilling into mild steel, aluminum, or heavy-gauge stainless steel, this 12.50mm bit provides the reliability and consistency required for high-quality metalworking. It is the ideal choice for professionals who demand efficiency and precision in every task.
