05E407 - Walter SST Corecut 1-7/16" x 2" Annular Cutter with Universal Shank

Advanced Core Drilling Technology

The Walter 05E407 SST Corecut Annular Cutter represents a significant advancement in hole-making technology for industrial fabrication. Engineered with a diameter of 1-7/16 inches and a cutting depth of 2 inches, this tool is designed to deliver precision and efficiency in the most demanding environments. The defining feature of this series is the proprietary Super Speed Tip (SST) bronze surface treatment. This specialized coating drastically alters the tribological properties of the cutter, minimizing friction at the cutting interface. By reducing heat generation, the SST treatment prevents work hardening of the material and extends the operational lifespan of the cutter, making it a cost-effective solution for high-volume production.

Beyond its surface treatment, the geometry of the Walter SST Corecut is optimized for performance. It features fully ground, extra-large flutes that facilitate rapid chip evacuation, a critical factor when drilling deep holes in gummy materials like aluminum or tough alloys like stainless steel. The modern tooth design ensures a smooth cutting action that eliminates porosity and leaves a burr-free finish, often negating the need for secondary reaming or deburring operations. This attention to geometric detail ensures that the cutter maintains structural integrity even under high feed rates.

Versatility is central to the design of the 05E407. Equipped with a universal shank, this annular cutter is compatible with a wide array of magnetic drilling units and stationary drill presses, eliminating the need for specialized adapters. Whether working on structural steel erection, heavy machinery assembly, or custom fabrication, the Walter SST Corecut delivers consistent, high-tolerance results. It is suitable for use on a broad spectrum of materials, including mild steel, structural steel, stainless steel, and aluminum, providing a singular solution for diverse drilling requirements.
