05E308 - Walter SST Core Cut Annular Cutter 1/2" x 2" Universal Shank

Technical Overview: Walter 05E308 SST Core Cut

The Walter 05E308 is a high-performance annular cutter from the SST Core Cut series, engineered to deliver precision and efficiency in industrial drilling operations. This specific model features a 1/2-inch diameter and a substantial 2-inch depth of cut, making it suitable for penetrating thick plates, structural beams, and heavy-walled pipe. The cutter is equipped with a universal shank, ensuring broad compatibility with a wide range of magnetic drilling units and stationary drill presses commonly found in fabrication shops and MRO environments.

At the core of this tool's performance is Walter's proprietary Super Speed Tip (SST) technology. The cutter undergoes an advanced surface treatment process that significantly reduces surface porosity. This treatment serves two critical technical functions: it minimizes the coefficient of friction between the tool and the workpiece, and it prevents the adhesion of material (galling), which is particularly beneficial when drilling gummy materials like aluminum or work-hardening alloys like stainless steel. The result is a substantial reduction in heat generation, which is the primary cause of tool failure in annular cutters.

Structurally, the 05E308 is designed with fully ground, extra-large flutes. This geometric feature optimizes the evacuation of metal chips, preventing clogging and binding deep within the cut. The modern tooth design balances cutting forces, ensuring a stable drilling process that produces burr-free holes with excellent surface finish. By requiring less energy to cut, this tool reduces wear on the drilling machine's motor while maximizing the lifespan of the cutter itself. It is an ideal solution for operators requiring consistent, high-tolerance holes in mild steel, structural steel, stainless steel, and aluminum.
