05E314 - Walter SST Core Cut Annular Cutter, 7/8-Inch x 2-Inch, Universal Shank

High-Performance Drilling with Walter SST Core Cut Technology

The Walter 05E314 SST Core Cut Annular Cutter represents the pinnacle of drilling efficiency for industrial applications. Engineered with Walter's proprietary Super Speed Tip (SST) technology, this 7/8-inch diameter cutter is designed to tackle the toughest materials, including structural steel, stainless steel, and aluminum. The defining feature of the SST series is its cutting-edge surface treatment, which effectively eliminates microscopic porosity on the tool's surface. This manufacturing breakthrough results in a flawlessly smooth finish that significantly reduces friction between the cutter and the workpiece.

Friction is the primary enemy of tool life in metal drilling, as it generates excess heat that can dull cutting edges prematurely. By minimizing this friction, the Walter SST Core Cut ensures that the tool runs cooler, even during intensive drilling operations. The cutter also features fully ground, extra-large flutes. These deep channels are optimized for rapid material evacuation, preventing chip clogging that can lead to binding or breakage. This is particularly important when drilling deeper holes, such as the 2-inch depth capacity offered by this model.

Versatility is key in a busy workshop, and the 05E314 delivers with its Universal Shank design. This standard shank configuration allows the cutter to be compatible with a wide range of magnetic drilling units and stationary machines without the need for complex adapters. Whether you are fabricating heavy structural components or performing precision maintenance on stainless steel equipment, this cutter provides the reliability and speed required to maintain productivity. The special bronze SST finish not only identifies the tool but actively contributes to its wear resistance, making it a long-lasting investment for any professional fabrication environment.
