05E010 - Walter SST Corecut 5/8-Inch Annular Cutter for Stainless Steel

Precision Core Drilling for Tough Materials

The Walter 05E010 SST Corecut Annular Cutter represents a pinnacle in hole-making technology, specifically engineered for the demanding requirements of industrial metalworking. Unlike traditional twist drills that remove all material from the hole, this annular cutter removes only a narrow periphery, ejecting the center as a solid slug. This method requires significantly less energy and thrust, allowing for faster penetration rates and reduced wear on the magnetic drilling machine. The 5/8-inch diameter and 1-inch depth of cut make it a versatile tool for structural fabrication, maintenance, and heavy-duty manufacturing environments.

The "SST" designation highlights this cutter's specialized formulation and geometry, optimized for stainless steel and other hard alloys. Drilling stainless steel presents unique challenges, primarily due to its tendency to work-harden if heat is not managed correctly. The Walter SST Corecut features advanced tooth geometry that promotes efficient chip evacuation and reduces friction. This design minimizes heat buildup at the cutting interface, preserving the temper of the cutter and preventing the workpiece from hardening during the operation. The result is a cleaner cut with extended tool life, even in the toughest materials.

A key feature of this model is its Universal Shank. In a market often divided between Weldon (two flat) and Nitto (One-Touch) shank styles, the Walter Universal Shank bridges the gap, offering compatibility with virtually all major magnetic drill brands. This eliminates the need for adapters or carrying duplicate inventory for different machines. The cutter is manufactured from premium high-speed steel (HSS) and undergoes a proprietary heat treatment process to ensure maximum hardness without brittleness, providing the reliability required for critical industrial applications.

Operators will appreciate the precision of the 05E010. Because annular cutters do not rely on a chisel point to start the hole, they do not wander. The result is a burr-free, accurate hole that typically requires no reaming or secondary finishing. Whether used in a workshop setting or on a remote job site, the Walter SST Corecut delivers consistent, high-performance results, reducing cycle times and lowering the cost per hole.
