01A513 - Walter SST+ 13/64 Inch Cobalt Drill Bit for Stainless Steel

High-Performance Drilling with Walter SST+ Technology

The Walter 01A513 13/64" SST+ Drill Bit represents the pinnacle of drilling technology for industrial applications. Designed to tackle the toughest materials, this drill bit is engineered with an exclusive cobalt blend that provides exceptional heat resistance and hardness. Unlike standard high-speed steel bits that can dull quickly when facing hard metals, the SST+ series maintains its cutting edge longer, making it the ideal choice for professionals working with stainless steel, mild steel, and non-ferrous alloys.

One of the standout features of this drill bit is its 135° split point geometry. This self-centering design eliminates the need for a center punch, allowing you to start drilling immediately with precision. It effectively prevents the bit from "walking" or wandering across the surface, which is particularly beneficial when drilling into round stock or curved surfaces. This ensures that every hole is positioned exactly where you intend it to be, reducing waste and rework.

Efficiency is further enhanced by Walter's innovative High Flow flute design. As the bit penetrates the material, the specialized flutes rapidly evacuate chips and debris from the hole. This action significantly reduces friction and heat buildup—the primary enemies of drill bit longevity. By keeping the cutting zone cooler, the bit retains its temper and structural integrity for a greater number of holes.

The Quick Shank feature on the 13/64" size ensures a positive lock within the drill chuck. Slippage inside the chuck is a common frustration that wastes energy and damages the bit shank; the Quick Shank design mitigates this, transferring maximum torque to the cutting tip. Finished with a unique bronze SST surface treatment, this bit not only looks professional but also benefits from reduced friction during operation. Whether you are using a portable drill or a stationary drill press, the Walter SST+ 13/64" bit delivers reliable, heavy-duty performance that industrial fabricators trust.
