05A313 - Walter SST Annular Cutter 13/16 Inch x 2 Inch Depth Universal Shank

Advanced Metallurgy for Precision Drilling

The Walter 05A313 SST Core Cut Annular Cutter represents the pinnacle of drilling technology for industrial fabrication. Designed with a diameter of 13/16 inches and a cutting depth of 2 inches, this tool is engineered to tackle the toughest materials found in modern manufacturing, including stainless steel, structural steel, and aluminum. The defining feature of the SST (Super Speed Tip) series is its advanced surface treatment technology. Walter utilizes a special bronze SST coating that effectively eliminates microscopic porosity on the cutter's surface. This results in an exceptionally smooth finish that serves a critical purpose: friction reduction.

In heavy-duty drilling, friction is the primary source of heat buildup, which leads to premature tool failure and work hardening of the material. By minimizing friction with the work surface, the Walter SST Core Cut operates at cooler temperatures, preserving the temper of the cutting edge and significantly extending the lifespan of the tool. This is particularly vital when working with stainless steel, a material notorious for work-hardening if the cutting tool generates excessive heat or dwells too long in the cut.

Beyond the surface treatment, the geometry of the cutter is optimized for high-performance material removal. The unit features fully ground, extra-large flutes that facilitate rapid chip evacuation. Efficient chip removal is essential to prevent clogging and binding, especially in deep hole drilling applications up to 2 inches. The modern tooth design works in tandem with the cutter geometry to deliver aggressive yet stable cutting action, reducing the time required per hole and increasing overall productivity. Equipped with a universal shank, this cutter is compatible with a wide array of magnetic drilling units and stationary machines, making it a versatile addition to any professional tool crib.

For operations that demand consistency, speed, and longevity, the Walter SST Core Cut offers a scientifically engineered solution that outperforms standard high-speed steel cutters. It transforms the drilling process from a bottleneck into a streamlined operation, delivering clean, burr-free holes with minimal effort.
