Walter SST Corecut 3/4-Inch Annular Cutter Universal Shank

Precision Holes in Tough Metals

Upgrade your magnetic drill's capabilities with the Walter 3/4" x 1" SST Corecut Annular Cutter. If you are a welder or fabricator who frequently works with stainless steel, you know the frustration of burning through standard bits. The Walter 05E012 is built to withstand the rigors of drilling hard materials. Unlike standard high-speed steel bits that dull quickly when they hit a hard spot, the SST Corecut series features a specialized hardening process that maintains a sharp cutting edge longer, even in 304 and 316 stainless steel.

This cutter is all about making your job easier and your finish better. The annular cutting action removes material only at the periphery of the hole, leaving a solid slug. This means you are turning less metal into chips, which translates to less heat and faster cutting speeds. The result is a clean, burr-free hole that often requires no secondary deburring or reaming. Whether you are mounting brackets, creating bolt holes in flanges, or fabricating custom frames, this tool ensures your holes are perfectly round and true to size every time.

The "Universal Shank" is a massive convenience feature for any shop with multiple drills. You don't need to worry about whether this bit will fit your specific mag drill model—it is designed to lock securely into almost all standard arbors, including Weldon and Nitto styles. This versatility, combined with Walter's legendary durability, makes the 05E012 an essential addition to your tool kit. Stop fighting with dull bits and work-hardened holes; switch to the Walter SST Corecut for a smoother, faster drilling experience.
