05A115 - Walter SST Core Cut Annular Cutter 1-15/16 Inch x 1 Inch Depth

Advanced Drilling Technology with Walter SST Core Cut

The Walter 05A115 SST Core Cut Annular Cutter represents a significant leap forward in hole-making technology for industrial applications. Designed with a diameter of 1-15/16 inches and a cutting depth of 1 inch, this tool is engineered to deliver precision and efficiency in the most demanding environments. The defining feature of this series is the Super Speed Tip (SST) surface treatment. Unlike standard high-speed steel cutters, the SST Core Cut undergoes a specialized treatment process that eliminates microscopic surface imperfections. This results in an ultra-smooth finish that drastically reduces friction between the tool and the workpiece.

Friction is the enemy of tool life, particularly in drilling operations where heat buildup can degrade the cutting edge and work-harden the material. By minimizing friction, the SST treatment ensures that the cutter runs cooler, maintaining its hardness and edge retention for significantly longer periods. This is complemented by the cutter's fully ground, extra-large flutes. These deep channels are designed to evacuate chips rapidly, preventing clogging and further reducing heat generation. The result is a tool that can sustain higher feed rates without compromising the quality of the hole or the integrity of the cutter.

Metallurgically, the Walter SST Core Cut is crafted to handle a diverse range of materials. It excels in drilling mild steel, structural steel, and is particularly effective on difficult-to-machine materials like stainless steel and aluminum. The universal shank design adds a layer of versatility, allowing this high-performance cutter to be utilized across a wide array of magnetic drilling units without the need for specialized adapters. For MRO professionals seeking a reliable, long-lasting solution for large diameter hole creation, the 05A115 offers a perfect balance of speed, durability, and precision engineering.
