05A613 - Walter SST Annular Cutter 13/16 Inch Diameter x 3 Inch Depth

High-Performance Drilling with Walter SST Technology

The Walter 05A613 13/16" x 3" SST Core Cutter represents a significant leap forward in hole-making technology for industrial applications. Designed for heavy-duty fabrication and MRO environments, this annular cutter utilizes Walter's proprietary Super Speed Tip (SST) surface treatment. Unlike standard high-speed steel cutters, the SST treatment effectively eliminates surface porosity. This microscopic smoothing of the cutter's surface drastically reduces friction between the tool and the workpiece, preventing heat buildup—the primary cause of premature tool failure. The result is a cutter that stays harder for longer, delivering consistent performance even in tough materials like stainless steel and structural alloys.

Efficiency is at the core of the 05A613's design. It features fully ground, extra-large flutes that are specifically engineered to evacuate chips rapidly. When drilling deep holes up to 3 inches, effective chip removal is critical to prevent binding and breakage. The modern tooth geometry works in tandem with the flute design to cut cleanly through the periphery of the hole, leaving a solid slug that is ejected upon completion. This method requires significantly less horsepower and thrust than traditional twist drilling, reducing wear on your magnetic drilling unit and operator fatigue.

Versatility is another key advantage of this Walter core cutter. It is equipped with a universal shank, making it compatible with a wide range of magnetic drilling units and stationary drill presses without the need for specialized adapters. Whether you are drilling through thick structural beams, stacking multiple sheets of steel, or working with aluminum components, the Walter SST Core Cutter delivers precise, burr-free holes with exceptional speed. It is an essential tool for shops prioritizing accuracy, speed, and tool longevity.
