OVERVIEW

Premium Performance for Industrial Drilling

The Walter 11/64" SST+ Drill Bit (SKU: 01A511) represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered specifically to address the challenges of drilling hard, high-tensile strength metals, this tool is manufactured from a premium cobalt blend (M35). Unlike standard high-speed steel (HSS) bits that soften and dull rapidly under high temperatures, the cobalt content in the SST+ series maintains hardness at elevated temperatures, making it the ideal choice for drilling stainless steel and other tough alloys.

Precision is paramount in professional environments, and the SST+ delivers with its 135° split point geometry. This self-centering design bites into the material immediately upon contact, effectively eliminating "walking" or skating across the workpiece. This feature removes the necessity for pre-punching holes, thereby streamlining the workflow and increasing productivity. The heavy-duty, fully ground body ensures concentricity, resulting in rounder, more accurate holes and reduced vibration during operation.

Chip evacuation is a critical factor in drill bit longevity. The Walter SST+ features a unique "High Flow" flute design that rapidly channels chips away from the cutting edge. This prevents chip packing and heat buildup—the primary causes of premature bit failure. Furthermore, the exclusive Bronze SST surface treatment acts as a lubricant, reducing friction between the bit and the hole wall. This combination of advanced geometry and surface technology allows for higher drilling speeds and significantly more holes per bit compared to conventional alternatives.

Whether utilized in a stationary drill press for repetitive manufacturing tasks or a portable hand drill for on-site maintenance, the 01A511 delivers consistent, reliable performance. It is robust enough to handle the rigors of heavy-duty fabrication while precise enough for delicate instrumentation work. For professionals seeking to minimize downtime and maximize tool life, the Walter SST+ is the definitive solution.

FAQ

The Walter SST+ drill bits are made from a premium cobalt blend (M35), which provides superior heat resistance and hardness compared to standard High-Speed Steel (HSS).

Yes, the SST+ series is specifically engineered for drilling stainless steel and other hard metals that generate significant heat during drilling.

No, the bit features a 135° self-centering split point that prevents walking, allowing you to start drilling precisely without a center punch.

The Bronze SST surface treatment reduces friction between the bit and the workpiece, allowing for smoother drilling and higher speeds while reducing heat buildup.

Absolutely. The quick-biting split point and efficient cutting action make it excellent for portable cordless drills where battery life and ease of use are important.

The 'High Flow' flute design is optimized to evacuate chips quickly from the hole. This prevents clogging and keeps the bit cooler, extending its lifespan.

The 01A511 SKU corresponds to a diameter of 11/64 inches.

Yes, like most high-quality twist drills, the Walter SST+ can be resharpened, though maintaining the specific split-point geometry requires proper sharpening equipment.
