05E104 - Walter SST+ Annular Cutter 1-1/4 Inch x 1 Inch Universal Shank

High-Performance Drilling for Tough Alloys

The Walter 05E104 SST+ Corecut Annular Cutter is a premium tooling solution designed for industrial professionals who demand precision and longevity. With a 1-1/4 inch diameter and a 1 inch depth of cut, this cutter is engineered to penetrate the hardest materials found in modern fabrication, including stainless steel and heavy structural plate. Unlike standard high-speed steel cutters that may struggle or work-harden when drilling stainless, the SST+ series utilizes a proprietary metallurgical formulation that resists heat buildup and maintains a sharp cutting edge for significantly longer periods.

Efficiency is at the core of the SST+ design. By cutting only the periphery of the hole and ejecting a solid slug, this tool requires far less horsepower and thrust than a comparable twist drill. This results in faster cycle times and reduced wear on your magnetic drilling machine. The Universal Shank is a critical feature for MRO environments, as it allows this single cutter to be compatible with a wide range of magnetic drills, including those using standard Weldon shanks and various quick-change systems (such as Nitto). This versatility reduces inventory complexity and ensures you always have the right tool for the machine at hand.

For shops that prioritize cost-per-hole metrics, the Walter SST+ stands out. It is fully resharpenable, meaning the initial investment continues to pay dividends long after the first project is complete. Whether used in field construction, maintenance repair, or production manufacturing, the 05E104 delivers clean, burr-free holes with exceptional consistency.
