01B547 - Walter SST+ Heavy Duty Cobalt Drill Bit - Wire Gauge #47

High-Performance Drilling with Walter SST+ Technology

The Walter 01B547 SST+ Jobber Drill Bit (Wire Gauge #47) represents the pinnacle of drilling efficiency for industrial applications. Designed to meet the rigorous demands of professional fabrication and maintenance, this drill bit is engineered from a specialized cobalt blend. This material composition provides exceptional heat resistance, allowing the bit to maintain its cutting edge even under the high thermal loads generated when drilling hard materials like stainless steel and heavy-gauge mild steel. Unlike standard high-speed steel bits that dull quickly, the SST+ series is built to last, reducing tool changeover time and increasing overall productivity.

One of the standout features of the Walter SST+ line is the exclusive "Speed Tip." This self-centering point geometry eliminates the common issue of bit wandering, known as "walking," especially when starting holes on round or curved surfaces. This precision allows operators to drill accurately without the prerequisite step of using a center punch, streamlining the workflow. Furthermore, the drill bit features a unique "High Flow" flute design. This geometry is optimized to evacuate chips rapidly from the hole, preventing clogging and heat accumulation that can lead to premature tool failure.

The body of the drill bit is back-tapered, a subtle but critical design element that reduces friction along the sides of the hole. Combined with Walter's proprietary bronze SST surface treatment, this ensures smooth operation with minimal binding. Whether utilized in a stationary drill press for repetitive manufacturing tasks or a portable hand drill for on-site maintenance, the Walter 01B547 delivers consistent, reliable performance. It is the tool of choice for professionals seeking to maximize holes-per-bit and minimize downtime in demanding metalworking environments.
