05E408 - Walter SST Corecut Annular Cutter 1-1/2 Inch x 2 Inch Depth Universal Shank

Advanced Drilling Performance with Walter SST Technology

The Walter 05E408 SST Corecut Annular Cutter represents the pinnacle of hole-making technology for industrial applications. Designed for professionals who demand precision and efficiency, this 1-1/2" diameter cutter features a 2" depth of cut, making it ideal for penetrating thick structural steel plates, heavy-wall pipe, and solid castings. The defining feature of this tool is the Super Speed Tip (SST) surface treatment. Unlike standard high-speed steel cutters, the SST Corecut undergoes a specialized process that eliminates microscopic porosity on the cutter's surface. This results in a flawlessly polished finish coated with a special bronze formulation.

This advanced surface treatment serves a critical function: friction reduction. By creating an ultra-smooth interface between the tool and the workpiece, the SST coating significantly limits heat generation. Heat is the enemy of cutting tools, particularly when working with work-hardening materials like stainless steel. The reduction in thermal stress preserves the temper of the cutting teeth, extending the service life of the cutter well beyond that of conventional alternatives. Furthermore, the fully ground, extra-large flutes are engineered to evacuate chips rapidly, preventing clogging and binding deep in the cut.

The 05E408 is equipped with a universal shank, ensuring seamless integration with a wide array of magnetic drilling units without the need for complex adapters. Whether you are drilling in the shop or on a remote job site, the reliability of the tooth geometry ensures consistent performance. The modern tooth design balances cutting forces, allowing for smooth penetration and a finish that often requires no secondary deburring operations. For MRO specialists and fabricators looking to optimize their drilling cycle times, the Walter SST Corecut offers a robust solution.
