05E404 - Walter SST Corecut Annular Cutter 1-1/4" x 2" Universal Shank

Precision Engineering for Industrial Fabrication

The Walter 05E404 SST Corecut Annular Cutter represents a significant advancement in hole-making technology for the industrial MRO and fabrication sectors. Designed with a 1-1/4" diameter and a 2" depth of cut, this tool addresses the common challenges associated with drilling tough materials like stainless steel and structural alloys. The defining feature of this series is the exclusive Super Speed Tip (SST) surface treatment. Unlike standard coatings, the SST bronze treatment is applied using a specialized process that eliminates microscopic porosity on the cutter's surface. This results in an exceptionally smooth finish that drastically reduces the coefficient of friction between the tool and the workpiece.

In heavy-duty drilling applications, heat generation and chip evacuation are critical factors influencing tool life and hole quality. The Walter SST Corecut mitigates these issues through its fully ground, extra-large flutes which facilitate rapid removal of material. By preventing chip packing and reducing thermal stress, the cutter maintains its hardness and cutting edge integrity over prolonged use. The modern tooth geometry is engineered to balance cutting forces, ensuring stability and precision even when operating at higher feed rates. This makes the 05E404 an ideal choice for high-volume production environments where downtime for tool changes must be minimized.

Compatibility is streamlined through the inclusion of a universal shank. This design feature allows the cutter to be utilized across a broad spectrum of magnetic drilling units and stationary machine tools without the need for specialized adapters. Whether integrated into a CNC setup or used in field maintenance with portable equipment, the Walter SST Corecut delivers consistent, burr-free performance. It is specifically optimized for structural steel, stainless steel, and aluminum, providing a versatile solution for diverse metallurgical requirements.
