05E311 - Walter SST Core Cut Annular Cutter 11/16-Inch x 2-Inch Universal Shank

High-Performance Drilling with Walter SST Corecut Technology

The Walter 05E311 SST Corecut Annular Cutter represents the pinnacle of hole-making technology for industrial fabrication. Designed with a precise 11/16-inch diameter and a generous 2-inch cutting depth, this tool is engineered to handle the most demanding drilling tasks in structural steel, stainless steel, and aluminum. The defining feature of this series is the exclusive Super Speed Tip (SST) bronze surface treatment. This advanced coating creates a flawlessly smooth finish on the cutter, drastically reducing friction between the tool and the workpiece. By minimizing heat generation—the primary cause of tool failure—the SST treatment ensures a significantly longer service life compared to standard high-speed steel cutters.

Efficiency is at the core of the Walter design. The cutter features fully ground, extra-large flutes that optimize material evacuation. In deep hole drilling, chip removal is critical to preventing binding and overheating; Walter’s geometry ensures chips are cleared rapidly, allowing for faster feed rates and cleaner cuts. The modern tooth design further enhances performance by delivering a smooth, burr-free finish that often eliminates the need for secondary reaming or deburring operations. This makes the 05E311 an essential asset for workshops focused on productivity and precision.

Versatility is ensured through the inclusion of a Universal Shank. This shank design allows the cutter to be used with a wide variety of magnetic drilling units and stationary machines without the need for complex adapters. Whether you are working on-site with a portable mag drill or in a fabrication shop with stationary equipment, the Walter SST Corecut delivers consistent, reliable performance. It is the ideal choice for MRO professionals and metalworkers who require durability, speed, and accuracy in every cut.
