05A100 - Walter SST Corecut 1-Inch Diameter x 1-Inch Depth Annular Cutter

High-Performance Drilling with Walter SST Corecut Technology

The Walter 05A100 1" x 1" SST Corecut Annular Cutter represents the pinnacle of hole-making technology for industrial fabrication. Designed to meet the rigorous demands of heavy-duty metalworking, this cutter utilizes Walter's proprietary SST (Super Surface Treatment) technology. This advanced bronze surface treatment is not merely a coating but a performance enhancer that significantly reduces the coefficient of friction between the tool and the workpiece. By minimizing friction, the cutter generates less heat during operation, which is the primary cause of tool failure and work hardening in sensitive materials like stainless steel.

Engineered for precision and efficiency, the SST Corecut features fully ground, extra-large flutes. These deep channels are critical for the rapid evacuation of chips, preventing clogging and binding even when drilling through thick structural steel or gummy aluminum alloys. The result is a cleaner, burr-free hole that often eliminates the need for secondary finishing operations such as reaming or deburring. The cutter's geometry is optimized to eliminate porosity, ensuring an impeccably smooth finish on the interior wall of the hole, which is essential for critical bolted connections and structural integrity.

Versatility is a key component of the 05A100's design. It features a universal shank that allows it to be used with a wide array of magnetic drilling units and stationary machines without the need for specialized adapters. Whether you are working in a fabrication shop or on a remote job site, this core cutter delivers consistent, reliable performance. It is specifically formulated to handle a broad range of materials, including mild steel, structural steel, stainless steel, and aluminum, making it an indispensable tool for MRO professionals and metalworkers seeking to maximize productivity and reduce tooling costs.
