05A412 - Walter SST Core Cut Annular Cutter 1-3/4" x 2" Universal Shank

High-Performance Walter SST Core Cut Annular Cutter

The Walter 05A412 SST Core Cut Annular Cutter represents the pinnacle of drilling technology for industrial fabrication. Designed with a substantial 1-3/4 inch diameter and a 2-inch cutting depth, this tool is engineered to handle the most demanding drilling tasks found in structural steel erection, heavy manufacturing, and MRO environments. The defining feature of this cutter is its exclusive Super Speed Tip (SST) technology, which incorporates a specialized bronze surface treatment. This advanced coating is not merely aesthetic; it plays a critical role in reducing the coefficient of friction between the tool and the workpiece. By minimizing friction, the cutter generates significantly less heat during operation, which is the primary enemy of tool life in metal drilling applications.

Beyond its surface treatment, the physical geometry of the Walter SST Core Cut is optimized for efficiency. It features fully ground, oversized flutes that provide a clear pathway for swarf and chips to escape the cutting zone. Efficient chip evacuation is essential when drilling deep holes or working with gummy materials like aluminum and stainless steel, as it prevents binding and ensures a clean, burr-free finish. The modern tooth design further enhances cutting aggression while maintaining stability, allowing operators to drill faster with less feed pressure. This results in reduced operator fatigue and less wear on the magnetic drilling unit itself.

Versatility is a key component of the 05A412's design. It is equipped with a universal shank, making it compatible with a wide array of magnetic drilling machines available on the market today. Whether you are using a Hougen, Nitto, or other major brand mag drill, this cutter is designed to fit securely and perform flawlessly. The cutter is rated for use on a variety of tough materials, including mild steel, structural steel, stainless steel, and aluminum. Its ability to maintain a sharp edge and resist heat buildup makes it particularly well-suited for drilling stainless steel, a material notorious for work-hardening and destroying lesser quality bits.

In summary, the Walter 05A412 offers a superior combination of speed, durability, and precision. By eliminating porosity through its surface treatment and optimizing chip flow with its flute design, it delivers exceptionally smooth finishes and reliable performance. For professionals requiring a 1-3/4" x 2" solution that reduces drilling time and increases productivity, the Walter SST Core Cut is the industry standard choice.
