Walter SST+ 13/64 Inch Cobalt Drill Bit for Stainless Steel

Unmatched Durability for Stainless Steel Applications

When precision and speed are non-negotiable, the Walter 13/64" SST+ Drill Bit (01A513) is the tool of choice for serious fabricators and welders. This bit is specifically formulated to overcome the challenges of drilling through work-hardening materials like stainless steel. The secret lies in its heavy-duty cobalt blend body, which offers superior resistance to the high temperatures generated during aggressive drilling. This results in a tool that cuts faster and lasts significantly longer than conventional bits, providing excellent value over its lifespan.

The geometry of the SST+ bit is optimized for ease of use and accuracy. It features a 135-degree split point, a critical specification for drilling hard metals. This point angle allows the bit to bite into the material instantly upon contact, reducing the feed pressure required by the operator. This "self-centering" capability is essential for maintaining accuracy, especially in portable drilling scenarios where stability can be a challenge. You can achieve clean, round holes without the bit skating across the workpiece.

Chip removal is handled effortlessly by the High Flow flute design. Efficient chip evacuation is vital for preventing the bit from binding or overheating. By clearing debris quickly, the SST+ bit maintains a cooler cutting temperature, which preserves the hardness of the cutting edges. Additionally, the body of the bit is fully ground, ensuring concentricity and balance that contributes to smoother operation and less vibration.

For secure power transmission, this bit utilizes Walter's Quick Shank technology. This shank design prevents the bit from spinning inside the chuck, a common issue that can mar the shank and reduce drilling efficiency. The bronze surface treatment adds a layer of lubricity and corrosion resistance. Suitable for a wide range of applications—from automotive repair to structural steel fabrication—the Walter 13/64" SST+ Drill Bit is a versatile and robust addition to any tool crib, delivering consistent results in the most demanding environments.
