05A308 - Walter SST Core Cut Annular Cutter 1/2" x 2" Universal Shank

High-Performance Industrial Drilling Solution

The Walter SST Core Cut Annular Cutter (SKU: 05A308) represents the pinnacle of hole-making technology for industrial fabrication and MRO applications. Engineered with Walter's proprietary Super Speed Tip (SST) technology, this 1/2-inch diameter cutter is designed to penetrate the toughest materials with exceptional speed and precision. The defining feature of this tool is its advanced surface treatment—a specialized bronze coating that effectively eliminates microscopic porosity on the cutter's surface. This ultra-smooth finish drastically reduces friction between the tool and the workpiece, thereby minimizing heat generation, which is the primary cause of premature tool failure in heavy-duty drilling operations.

With a 2-inch depth of cut, this cutter is versatile enough to handle thick plate steel, structural beams, and heavy-wall pipe. The geometry of the cutter includes fully ground, extra-large flutes that facilitate rapid chip evacuation. Efficient chip removal is critical when drilling deep holes, as it prevents clogging and binding, ensuring a continuous and smooth cutting action. The modern tooth design is optimized to distribute cutting forces evenly, allowing for faster feed rates without compromising the integrity of the tool or the quality of the hole.

Compatibility is a key consideration for industrial tooling, and the Walter 05A308 excels with its universal shank design. It readily fits a wide array of magnetic drilling units and stationary machines, making it a flexible addition to any tool crib. Whether working with mild steel, stainless steel, or aluminum, the SST Core Cut delivers consistent, burr-free results. By cutting only the periphery of the hole and ejecting the center as a solid slug, it requires significantly less power and torque than traditional twist drills, leading to less wear on your machinery and faster cycle times for your operators.

Invest in the Walter SST Core Cut for your operations to experience reduced downtime, extended tool life, and superior hole quality. It is the ideal choice for structural steel erectors, metal fabricators, and maintenance professionals who demand reliability and efficiency in every cut.
