05E100 - Walter SST Corecut Annular Cutter 1-Inch Diameter Universal Shank

High-Performance Drilling for Stainless Steel

The Walter 05E100 SST Corecut Annular Cutter represents the pinnacle of hole-making technology specifically designed for challenging materials like stainless steel. In industrial fabrication and MRO environments, drilling through stainless steel often presents significant difficulties due to the material's tendency to work-harden and its high tensile strength. Standard high-speed steel (HSS) cutters often fail prematurely or produce inferior finishes. The SST Corecut series addresses these issues with a specialized geometry and material composition optimized for tough alloys.

This cutter features a 1-inch diameter and a 1-inch depth of cut, making it a versatile tool for creating clean, burr-free holes in plate and structural steel. The "SST" designation indicates its primary application: Stainless Steel. By utilizing advanced metallurgy, Walter Surface Technologies has created a cutter that maintains its cutting edge longer, reduces heat generation, and minimizes the torque required to penetrate the workpiece. This results in faster cycle times and reduced wear on the magnetic drilling machine.

Universal Compatibility and Design

One of the key features of the 05E100 is its Universal Shank. This design innovation ensures compatibility with a wide array of magnetic drill presses available on the market, including those utilizing the standard Weldon shank system and other quick-change mechanisms. This universality reduces inventory requirements for shops with mixed equipment fleets.

• Diameter: 1 Inch


• Depth of Cut: 1 Inch


• Shank Style: Universal (Fits Weldon & Nitto)


• Application: Stainless Steel, Structural Steel

The core drilling process removes material only at the periphery of the hole, ejecting a solid slug upon completion. This method is significantly more efficient than twist drilling, as it converts less metal into chips and requires less thrust. For MRO professionals, this means less operator fatigue and faster project turnaround. The Walter 05E100 is an essential consumable for any operation dealing with heavy-duty stainless steel fabrication.
