05E405 - Walter SST Core Cut Annular Cutter 1-5/16 x 2 Inch Universal Shank

High-Performance Drilling with Walter SST Corecut Technology

The Walter 05E405 SST Corecut Annular Cutter represents the pinnacle of hole-making technology for industrial fabrication. Designed with a diameter of 1-5/16 inches and a cutting depth of 2 inches, this tool is engineered to deliver precision and speed in the most demanding environments. The defining feature of this series is the Super Speed Tip (SST) surface treatment. This exclusive bronze coating is not merely aesthetic; it is a functional surface hardening treatment that eliminates microscopic porosity on the cutter's surface. By creating an exceptionally smooth finish, the SST treatment significantly reduces friction between the tool and the workpiece, thereby minimizing heat generation—the primary cause of premature tool failure.

Beyond the surface treatment, the geometry of the Walter Corecut is optimized for efficiency. The cutter features fully ground, extra-large flutes that facilitate rapid chip evacuation. In deep hole drilling, effective chip removal is critical to preventing binding and overheating. The modern tooth design works in tandem with the flute geometry to slice through tough materials like stainless steel and structural steel with less resistance than conventional cutters. This results in a cleaner hole with fewer burrs, often eliminating the need for secondary reaming or deburring operations.

Versatility is also a key component of the 05E405's design. It is equipped with a universal shank, ensuring compatibility with a wide range of magnetic drilling units and stationary machines. Whether you are working in a fabrication shop or on a remote job site, this cutter integrates seamlessly into your existing tooling setup. The robust construction and advanced materials ensure that the Walter SST Corecut maintains its cutting edge longer, providing a lower cost per hole and higher productivity for industrial operators.
