05E013 - Walter SST+ 13/16 Inch Annular Cutter for Stainless Steel

High-Performance Drilling for Tough Alloys

The Walter 05E013 is a premium 13/16-inch annular cutter from the renowned SST+ Corecut series, engineered to address the specific challenges of drilling stainless steel and other hard metal alloys. Unlike standard high-speed steel cutters that may dull rapidly when encountering the work-hardening characteristics of stainless steel, the SST+ line utilizes a proprietary HSS blend and advanced geometry. This design ensures that the cutting edge remains sharp longer, maintaining consistent feed rates and reducing the mechanical load on magnetic drilling units.

This cutter features a 1-inch depth of cut capability, making it suitable for a wide range of structural and fabrication applications involving plate and tubing. The core drilling process is inherently more efficient than twist drilling, as it removes only the periphery of the hole, converting a smaller volume of metal into chips. This results in significantly lower energy consumption and faster penetration times. The 05E013 is designed to eject the center slug cleanly at the end of the cut, provided the appropriate pilot pin is utilized.

A key feature of this model is its Universal Shank. This shank design incorporates multiple flats and connection points, allowing it to interface seamlessly with a vast array of magnetic drill presses, including those using Weldon style arbors and quick-change systems like Nitto Kohki. This universality reduces inventory complexity for tool cribs and ensures that the cutter can be deployed immediately on almost any available machine on the shop floor. The cutter is also fully resharpenable, offering a sustainable tooling solution that maximizes return on investment over the product's lifecycle.

Technical Specifications

The geometry of the SST+ Corecut is optimized for chip evacuation. In stainless steel applications, heat management is critical; the flute design of the 05E013 promotes rapid chip flow, carrying heat away from the workpiece and the cutting edges. This reduces the risk of thermal expansion seizing the cutter or altering the metallurgy of the surrounding material. For optimal performance, it is recommended to use this cutter in conjunction with high-quality cutting lubricants or coolants specifically designed for stainless steel operations.
