05H309 - Walter Carbide Core Cut Annular Cutter, 9/16-Inch x 2-Inch Depth, Universal Shank

High-Performance Carbide Tooling for Industrial Drilling

The Walter 05H309 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for industrial maintenance, repair, and operations (MRO). Designed to meet the rigorous demands of modern fabrication, this 9/16-inch diameter cutter features a 2-inch depth of cut, allowing for deep penetration in structural steel, heavy plate, and pipe. Unlike traditional High-Speed Steel (HSS) cutters, the Core Cut series utilizes premium carbide inserts that significantly enhance hardness and heat resistance. This metallurgical advantage enables the tool to maintain its cutting edge even when processing abrasive materials such as cast iron, tough alloys, and work-hardening stainless steel.

Engineering precision is at the heart of the 05H309. The cutter incorporates a sophisticated flute and body design that optimizes chip evacuation, a critical factor in preventing heat buildup and ensuring hole accuracy. By efficiently removing debris from the cutting zone, the tool reduces friction and allows for higher feed rates and rotational speeds. This efficiency translates to reduced cycle times and increased throughput in production environments. Furthermore, the robust construction of the carbide tips minimizes vibration and deflection, resulting in burr-free holes that often eliminate the need for secondary reaming or deburring operations.

Versatility is a key component of the Walter Carbide Core Cut design. The tool is equipped with a universal shank, engineered to be compatible with a wide array of magnetic drilling units available on the market, including those utilizing Weldon and Nitto-style arbors. This universal compatibility simplifies inventory management for tool cribs and ensures that the cutter can be deployed across various machines without the need for specialized adapters. Whether drilling on flat surfaces, curved pipes, or uneven materials, the Walter 05H309 delivers consistent, reliable performance that industrial professionals trust for their most challenging applications.
