05A505 - Walter SST Core Cutter - 2-5/16 in Diameter x 2 in Depth - Universal Shank Annular Cutter

Advanced Drilling Technology for Precision Fabrication

The Walter 05A505 SST Core Cutter is a premier tooling solution designed for industrial fabricators who demand precision, speed, and longevity from their drilling equipment. Part of Walter's renowned SST (Surface Treatment Technology) series, this 2-5/16 inch diameter cutter is engineered to overcome the common challenges associated with heavy-duty metal drilling. The core of its performance lies in the proprietary bronze SST surface treatment. Unlike standard high-speed steel cutters that can suffer from microscopic surface irregularities, the SST process eliminates porosity, creating a flawlessly smooth finish. This reduction in surface friction is critical; it significantly lowers the heat generated during the cutting process, preserving the temper of the tool and preventing work-hardening of the material being drilled.

Efficiency in material removal is paramount when drilling large diameter holes. This cutter features a modern tooth design coupled with fully ground, extra-large flutes. This geometry ensures that chips are evacuated rapidly and cleanly, preventing clogging and binding even when drilling through thick plate or structural beams up to 2 inches deep. The result is a cleaner hole with fewer burrs, reducing the need for secondary finishing operations. The cutter is robust enough to handle a wide range of materials, including mild steel, structural steel, stainless steel, and aluminum, making it a versatile asset in any machine shop or fabrication floor.

Compatibility is key for modern tooling inventories. The Walter SST Core Cutter utilizes a universal shank design, making it compatible with virtually all major brands of magnetic drilling units, including Hougen, Nitto, and others. This universality allows shop managers to standardize their tooling without worrying about machine-specific fitment issues. Whether used in stationary drill presses or portable magnetic drills on a job site, the 05A505 delivers consistent, high-performance results. By reducing drilling time and extending tool life, this cutter directly contributes to lower production costs and increased throughput for complex fabrication projects.
