05A501 - Walter SST Core Cut Annular Cutter 2-1/16" x 2" Depth

High-Performance Drilling with Walter SST Corecut Technology

The Walter 05A501 SST Corecut is a premium annular cutter designed to redefine efficiency in industrial drilling operations. Sized at a substantial 2-1/16 inches in diameter with a 2-inch depth of cut, this tool is engineered for heavy fabrication tasks where precision and speed are paramount. The defining feature of this series is the Super Speed Tip (SST) technology. This involves a specialized bronze surface treatment that drastically reduces the coefficient of friction between the cutter and the workpiece. By minimizing friction, the cutter generates significantly less heat during operation, which is the primary enemy of tool longevity. This allows for sustained high-performance drilling even in tough materials like stainless steel.

Beyond the coating, the physical geometry of the cutter is optimized for material removal. It features fully ground, extra-large flutes that facilitate rapid chip evacuation. In deep hole drilling, chip packing can often lead to tool breakage or poor surface finish; the SST Corecut's design ensures that waste material is cleared effectively, maintaining a clean cutting path. The modern tooth design works in tandem with the flute geometry to eliminate porosity, delivering a hole finish that is virtually burr-free and often requires no secondary finishing operations.

This cutter is built for versatility across the shop floor. It is compatible with both magnetic drilling units and stationary machines, thanks to its universal shank design. Whether you are working on structural steel erection, heavy machinery assembly, or custom fabrication involving aluminum and stainless alloys, the Walter SST Corecut delivers consistent, reliable results. It represents a fusion of advanced metallurgy and practical engineering, ensuring that every hole drilled is precise, clean, and achieved with maximum efficiency.
