05H406 - Walter 1-3/8 Inch Carbide Core Cut Annular Cutter with Universal Shank

High-Performance Carbide Drilling for Tough Materials

The Walter 05H406 Carbide Core Cut Annular Cutter is an industrial-grade drilling solution engineered for the most demanding metalworking environments. Measuring 1-3/8 inches in diameter with a 2-inch depth of cut, this cutter is specifically designed to overcome the challenges of drilling into hard, abrasive, and difficult-to-machine materials. Unlike traditional High-Speed Steel (HSS) cutters which may dull quickly or overheat when facing stainless steel or cast iron, this carbide-tipped tool maintains its cutting edge integrity even under high thermal stress.

At the heart of its performance is the advanced carbide insert technology. These extra-hard inserts allow the cutter to penetrate tough alloys and composites with significantly higher speed and feed rates. This translates to reduced cycle times and increased productivity on the shop floor. The cutter features a sophisticated flute and body design that optimizes chip flow, preventing clogging and heat buildup inside the hole. This is particularly critical when drilling deep holes up to 2 inches, ensuring that the cutter runs cool and smooth throughout the operation.

Versatility is a key component of the 05H406's design. It utilizes a Universal Shank, making it compatible with a wide array of magnetic drilling units, including popular brands like Hougen and Nitto. Whether you are working on flat plate, structural beams, or even curved surfaces like pipes, this cutter delivers precise, burr-free holes with minimal effort. It is the ideal choice for MRO professionals and fabricators who require reliability and precision when working with materials that typically pose a challenge to standard tooling.
