05A105 - Walter SST Core Cut Annular Cutter 1-5/16 Inch Diameter 1 Inch Depth

Precision Engineering for Heavy-Duty Drilling

The Walter 05A105 SST Corecut is a premium 1-5/16" x 1" annular cutter designed to redefine efficiency in industrial drilling operations. At the heart of this tool's performance is Walter's proprietary Super Speed Tip (SST) technology. This advanced manufacturing process involves a specialized bronze surface treatment that eliminates microscopic surface imperfections on the cutter. By creating an exceptionally smooth finish, the SST Corecut drastically reduces friction between the tool and the workpiece. Less friction means less heat generation, which is the primary enemy of cutting tool longevity. This makes the 05A105 particularly effective when drilling through tough materials like stainless steel and structural steel, where work-hardening and heat buildup can often lead to premature tool failure.

Beyond the surface treatment, the geometry of the Walter SST Corecut is engineered for maximum material removal rates. The cutter features fully ground, extra-large flutes that spiral up the body of the tool. These deep channels are critical for evacuating chips rapidly, preventing clogging that can slow down the drilling process or damage the cutter. The modern tooth design works in tandem with the flute geometry to slice through metal cleanly, leaving a burr-free hole that typically requires no secondary finishing operations. This level of precision is essential for fabrication shops where accuracy and speed are paramount.

Versatility is another key advantage of the 05A105. It is equipped with a universal shank, making it compatible with a wide array of magnetic drilling units and stationary machines available on the market today. Whether you are working with Nitto, Hougen, or other standard magnetic drill arbors, this cutter is designed to fit securely and transmit torque efficiently. For industrial MRO professionals and metal fabricators looking for a reliable, high-performance solution for drilling 1-5/16" holes up to 1" deep, the Walter SST Corecut offers a blend of durability, speed, and precision that stands out in the abrasives and cutting tool category.
