01B513 - Walter SST+ Cobalt Jobber Drill Bit #13 (0.1850")

Unmatched Performance in Industrial Maintenance Drilling

The Walter 01B513 SST+ Jobber Drill Bit #13 represents the pinnacle of drilling technology for Maintenance, Repair, and Operations (MRO) professionals. In industrial environments, time is money, and equipment downtime due to broken or dull tooling can be costly. Standard high-speed steel bits often fail when confronted with the hardened materials found in modern machinery, such as stainless steel frames or abrasive alloys. The Walter SST+ series is engineered to overcome these challenges, providing a robust solution that maintains its cutting edge far longer than conventional alternatives.

Advanced Cobalt Blend Technology

At the core of the 01B513 is a proprietary cobalt blend. Unlike standard HSS bits that soften under the intense heat generated by drilling hard metals, this cobalt-enriched formulation retains its hardness at elevated temperatures. This makes it the ideal choice for drilling through stainless steel, where work-hardening can destroy lesser bits in seconds. The addition of a special bronze SST surface treatment further enhances performance by significantly reducing friction. This coating acts as a lubricant, allowing the bit to rotate more freely within the hole, thereby reducing heat buildup and preventing the bit from welding to the workpiece.

Precision Geometry for Efficiency

Efficiency in the workshop is driven by precision. The Walter SST+ features an exclusive self-centering "Speed Tip." This 135-degree split point geometry allows the operator to place the drill bit exactly where the hole is needed without the bit "walking" or skating across the surface. This eliminates the need for pre-punching center marks, streamlining the workflow. Furthermore, the "High Flow" flute design is engineered to evacuate chips rapidly. In deep hole applications, efficient chip removal is critical to prevent clogging and binding. The back-tapered body design works in tandem with the flutes to reduce contact area with the sidewalls, minimizing torque requirements and reducing the risk of snapping the bit.

Versatility Across Materials

While optimized for stainless steel, the Walter #13 SST+ drill bit is a versatile workhorse capable of drilling mild steel, non-ferrous metals, and aluminum with equal proficiency. Whether you are repairing conveyor systems, fabricating custom brackets, or performing general facility maintenance, this drill bit delivers consistent, round, and burr-free holes. It is compatible with both stationary drill presses and portable hand drills, making it an essential component of any industrial tool crib.
