05A409 - Walter SST Core Cut Annular Cutter 1-9/16" x 2" Universal Shank

High-Performance Industrial Drilling Solution

The Walter 05A409 SST Core Cut Annular Cutter is engineered for industrial professionals who demand precision, speed, and durability in their metalworking operations. Measuring 1-9/16 inches in diameter with a 2-inch depth of cut, this tool represents the pinnacle of core drilling technology. At the heart of its performance is the Super Speed Tip (SST) technology, a proprietary bronze surface treatment that significantly alters the dynamics of the drilling process. By reducing the coefficient of friction between the tool and the workpiece, the SST coating minimizes heat generation—the primary cause of tool failure—thereby extending the service life of the cutter even under rigorous use.

Beyond its advanced coating, the physical geometry of the Walter SST Core Cut is designed for maximum efficiency. It features fully ground, extra-large flutes that facilitate rapid chip evacuation. In deep hole drilling, chip buildup can cause binding and overheating; the spacious flutes of the 05A409 ensure that material is cleared effectively, maintaining a clean cutting path. The modern tooth design works in tandem with the cutter geometry to eliminate porosity, delivering an exceptionally smooth finish that often negates the need for secondary reaming or deburring operations. This level of finish is critical in structural steel fabrication and high-precision manufacturing environments.

Versatility is a key component of the Walter 05A409's design. Equipped with a universal shank, this annular cutter is compatible with a wide array of magnetic drilling units and stationary machines, making it a flexible addition to any tool crib. It is specifically formulated to handle a broad spectrum of materials, including aluminum, mild steel, structural steel, and notoriously difficult stainless steel. For maintenance, repair, and operations (MRO) teams, having a reliable cutter that performs consistently across different substrates reduces downtime and inventory complexity. Trust Walter's engineering to deliver a drilling solution that enhances productivity and ensures structural integrity in every hole drilled.
