05A415 - Walter SST Core Cut Annular Cutter 1-15/16 Inch x 2 Inch Depth

High-Performance Drilling with Walter SST Technology

The Walter 05A415 SST Core Cut is a premium annular cutter engineered for the most demanding industrial drilling applications. Designed with a diameter of 1-15/16 inches and a cutting depth of 2 inches, this tool represents the pinnacle of hole-making efficiency. At the heart of its performance is Walter's proprietary Super Speed Tip (SST) technology. This advanced bronze surface treatment is not merely a coating but a functional enhancement that significantly reduces the coefficient of friction between the tool and the workpiece. By minimizing friction, the cutter generates less heat during operation, which is the primary cause of tool failure and work hardening in sensitive materials like stainless steel.

Structurally, the cutter features fully ground, extra-large flutes that spiral aggressively to evacuate chips rapidly. Efficient chip removal is critical in deep hole drilling to prevent binding and heat buildup. The modern tooth geometry is precision-ground to bite cleanly into the material, eliminating the porosity often seen with inferior cutters and leaving a burr-free, mirror-like finish that rarely requires secondary reaming or deburring. This attention to geometry and surface treatment ensures that the SST Core Cut maintains its cutting edge longer, providing a lower cost per hole over the lifespan of the tool.

Ideal for use with magnetic drilling units and stationary machines, this cutter excels in a wide range of materials, including structural steel, aluminum, and difficult-to-machine stainless steel alloys. The robust construction resists breakage under heavy load, making it a reliable choice for fabrication shops, structural steel erection, and heavy equipment manufacturing. When precision, speed, and tool longevity are non-negotiable, the Walter SST Core Cut stands as the superior solution for professional machinists and fabricators.
