01A510 - Walter SST+ 5/32" Cobalt Blend Jobber Drill Bit

High-Performance Drilling for Tough Alloys

The Walter 01A510 5/32" SST+ Drill Bit represents the pinnacle of drilling technology for maintenance, repair, and operations (MRO) professionals who demand reliability and speed. Engineered specifically to tackle the challenges of work-hardening materials, this drill bit features a proprietary cobalt blend body that maintains hardness even under the high temperatures generated when drilling stainless steel and other ferrous alloys. Unlike standard high-speed steel (HSS) bits that dull rapidly in tough applications, the SST+ series is built to withstand thermal stress, ensuring a significantly longer service life and reduced cost per hole.

Precision is paramount in industrial environments, and the SST+ delivers with its 135° split point geometry. This self-centering design eliminates the need for a center punch, preventing the bit from "walking" or skating across the workpiece surface upon initial contact. This feature is particularly beneficial when working on rounded surfaces or in awkward positions where stability is difficult to maintain. The heavy-duty, fully ground body ensures excellent concentricity, resulting in rounder, more accurate holes that meet tight tolerance requirements.

Chip evacuation is a critical factor in drilling efficiency, and Walter has addressed this with their unique "high flow" flute design. The geometry of the flutes is optimized to eject chips rapidly, preventing clogging and heat buildup inside the hole. Combined with the exclusive bronze SST surface treatment, which acts as a lubricant to reduce friction, this drill bit cuts faster and cooler than competitors. Whether utilized in a stationary drill press or a portable hand drill, the Walter 01A510 provides the consistent performance required for professional fabrication and assembly tasks.

Technical Excellence

The combination of material science and geometric precision makes the SST+ a versatile tool. It is capable of drilling mild steel, non-ferrous metals, and stainless steel with equal proficiency. The robust web construction adds rigidity, reducing the risk of breakage under heavy feed pressure. For industrial users seeking to minimize downtime and maximize productivity, the Walter SST+ 5/32" bit is the superior choice.
