05E309 - Walter SST Corecut 9/16 Inch x 2 Inch Annular Cutter Universal Shank

Walter SST Corecut Annular Cutter 9/16" x 2"

The Walter 05E309 SST Corecut is a premium annular cutter designed for heavy-duty industrial drilling applications. Featuring a 9/16-inch diameter and a 2-inch depth of cut, this tool is engineered to deliver precision holes in tough materials including stainless steel, structural steel, and aluminum. The defining feature of the SST Corecut series is its specialized bronze SST surface treatment. This advanced coating significantly reduces friction and heat generation during the drilling process, preventing work hardening and extending the service life of the cutter.

Constructed with fully ground extra-large flutes, the 05E309 ensures rapid chip evacuation, which is critical for maintaining cutting speed and accuracy in deep hole drilling. The contemporary tooth geometry is optimized to bite into the material cleanly, eliminating porosity and leaving a burr-free finish that often requires no secondary operations. This efficiency translates to reduced drilling time and lower cost per hole for fabrication shops and maintenance teams.

Equipped with a universal shank, this core cutter is compatible with a wide range of magnetic drilling units and stationary machines, making it a versatile addition to any tool crib. Whether working on structural steel erection or precision fabrication, the Walter SST Corecut provides the reliability and performance professionals demand.
