05A113 - Walter SST Corecut 1-13/16" x 1" Annular Cutter with Universal Shank

Advanced Drilling Technology for Industrial Fabrication

The Walter 05A113 SST Corecut Annular Cutter represents the pinnacle of hole-making technology for industrial applications. Engineered with Walter's proprietary Super Speed Tip (SST) technology, this 1-13/16" diameter cutter is designed to address the most common challenges faced during heavy-duty drilling operations. The core innovation lies in its advanced surface treatment—a specialized bronze coating that significantly alters the tribological properties of the tool. This treatment drastically reduces the coefficient of friction between the cutter and the workpiece, minimizing heat generation. Since heat is the primary enemy of cutting tool longevity and hole quality, the SST Corecut ensures that the structural integrity of the metal remains uncompromised while extending the lifespan of the cutter itself.

Beyond the surface treatment, the physical geometry of the 05A113 is meticulously crafted for efficiency. It features fully ground, extra-large flutes that facilitate rapid chip evacuation. In deep hole drilling or when working with gummy materials like aluminum or certain grades of stainless steel, chip packing can lead to catastrophic tool failure. The SST Corecut's design ensures that swarf is ejected smoothly, allowing for continuous drilling without the need for frequent peck cycles. The cutter is manufactured to eliminate porosity, resulting in an impeccably smooth finish on the interior of the hole, often negating the need for secondary reaming or finishing operations.

This tool is equipped with a universal shank, making it compatible with a vast array of magnetic drilling units and stationary machines. Whether deployed in a fabrication shop or on a remote job site, the Walter SST Corecut delivers consistent, high-precision performance. It is specifically optimized for drilling through mild steel, structural steel, stainless steel, and aluminum, providing MRO professionals and distributors with a versatile solution that reduces inventory complexity while maximizing operational throughput.
