01B518 - Walter SST+ #18 Cobalt Jobber Drill Bit for Stainless Steel

High-Performance Drilling with Walter SST+ Technology

The Walter #18 SST+ Jobber Drill Bit (SKU: 01B518) represents the pinnacle of drilling efficiency for industrial applications. Designed specifically for maintenance, repair, and operations (MRO) professionals who demand reliability, this drill bit is engineered to tackle the toughest materials found in modern workshops. At the core of its performance is a proprietary cobalt blend that provides exceptional heat resistance and hardness, making it the ideal choice for drilling through stainless steel, mild steel, and other non-ferrous heavy metals.

One of the standout features of the SST+ series is the exclusive "Speed Tip." This self-centering point geometry allows operators to drill immediately upon contact with the material, completely eliminating the need for pre-punching or pilot holes. This feature is particularly valuable when working on round surfaces or in awkward positions where tool walking can damage the workpiece. The 135-degree split point ensures aggressive cutting action that reduces the axial force required, thereby reducing operator fatigue during repetitive drilling tasks.

Thermal management is critical in metal drilling, and Walter has addressed this with a unique "High Flow" flute design. These flutes are optimized to evacuate chips rapidly, preventing heat buildup that can anneal the workpiece or dull the bit. Furthermore, the bit features a specialized bronze SST surface treatment. This coating not only protects the tool from oxidation but also acts as a solid lubricant, significantly reducing friction between the bit and the hole wall. The result is a drill bit that cuts faster, stays cooler, and lasts significantly longer than standard high-speed steel bits.

Whether utilized in a stationary drill press or a portable hand drill, the Walter 01B518 delivers consistent, precise holes with minimal burr formation. Its back-tapered body design further prevents binding, ensuring smooth retraction even from deep holes. For professionals seeking to maximize productivity and minimize tool replacement costs, the Walter SST+ #18 is the superior choice.
