05H311 - Walter 11/16" x 2" Carbide Core Cut Annular Cutter with Universal Shank

High-Performance Carbide Annular Cutter for Tough Alloys

The Walter 05H311 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for industrial fabrication. Engineered with premium carbide inserts, this 11/16-inch cutter with a 2-inch depth of cut is specifically designed to tackle the most challenging materials found in heavy industry, including stainless steel, cast iron, and abrasive alloys. Unlike standard High-Speed Steel (HSS) cutters, the carbide tips on this tool maintain their hardness at high temperatures, allowing for significantly faster feed rates and longer tool life.

Industrial operators rely on the Carbide Core Cut series for its ability to produce burr-free, precise holes without the need for pilot drilling or step drilling. The advanced flute geometry efficiently evacuates chips, reducing heat buildup and preventing work hardening in sensitive materials like stainless steel. This makes it an essential tool for structural steel erection, heavy equipment repair, and custom fabrication shops where efficiency and precision are paramount.

The universal shank design ensures compatibility with a wide range of magnetic drilling units, providing versatility across different machine brands. Whether working on flat plates or curved surfaces such as pipes, the robust body design minimizes vibration, ensuring a clean cut every time. By focusing the cutting action on the periphery of the hole, this annular cutter requires less power and thrust than twist drills, reducing wear on your magnetic drill motor while maximizing throughput.
