The Walter 01A531 SST+ 31/64" Drill Bit is engineered for the most demanding industrial applications. When precision and speed are non-negotiable, the SST+ series delivers with a proprietary cobalt blend that significantly outperforms standard high-speed steel. This composition provides the thermal resistance necessary to drill through work-hardening materials like stainless steel without dulling prematurely.
Walter has integrated a unique "High Flow" flute design into this bit, which is critical for deep hole drilling. This geometry ensures that chips are evacuated rapidly from the cutting zone, reducing friction and heat buildup—the primary enemies of drill bit longevity. The heavy-duty fully ground body ensures that the bit maintains its structural integrity even under high torque loads, providing a straight, accurate hole every time.
Designed with the professional in mind, the 135-degree split point allows for instant engagement with the material. This self-centering feature eliminates the need for a center punch and prevents the bit from "walking" across the surface, ensuring accuracy from the very first rotation. Whether you are working in maintenance, repair, or production, the Walter SST+ 31/64" bit offers the reliability required to keep operations moving smoothly.
