05A310 - Walter SST Core Cut 5/8" x 2" Annular Cutter with Universal Shank

High-Performance Drilling with Walter SST Technology

The Walter 05A310 SST Core Cut Annular Cutter represents the pinnacle of hole-making technology for industrial fabrication. Engineered with Walter's exclusive Super Speed Tip (SST) surface treatment, this 5/8-inch diameter cutter is designed to withstand the rigors of heavy-duty drilling in the toughest materials. The bronze SST coating is not merely a cosmetic finish; it is a functional surface treatment that drastically reduces friction between the tool and the workpiece. By minimizing heat generation—the primary enemy of cutting tools—the SST Core Cut ensures a longer service life and maintains cutting edge integrity even when drilling through work-hardened stainless steel or thick structural plate.

Beyond the coating, the geometry of the 05A310 is optimized for efficiency. It features fully ground, extra-large spiral flutes that facilitate rapid chip evacuation. In deep hole drilling (up to the 2-inch depth capacity of this model), effective chip removal is critical to prevent binding and breakage. The modern tooth design cuts aggressively yet smoothly, requiring less feed pressure from the operator or the magnetic drilling unit. This results in cleaner, burr-free holes that often eliminate the need for secondary reaming or deburring operations.

Versatility is a key component of the SST Core Cut design. The cutter utilizes a universal shank, making it compatible with a wide array of magnetic drilling machines, including those from major brands like Hougen, Nitto, and Jancy. Whether utilized in a fabrication shop or on a remote job site, this cutter delivers consistent, precision performance. It is the ideal choice for MRO professionals seeking to maximize productivity and minimize tooling costs per hole.
