05D403 - Walter 1-3/16 Inch Carbide Tipped Annular Cutter 2 Inch Depth

High-Performance Drilling for Tough Materials

The Walter 05D403 1-3/16" x 2" Carbide Core Cut Annular Cutter represents the pinnacle of hole-making technology for industrial applications involving hard and abrasive metals. Designed to outperform traditional High-Speed Steel (HSS) cutters, this carbide-tipped tool is engineered specifically to tackle the most challenging materials found in modern fabrication, including stainless steel, cast iron, and high-tensile alloys. When precision and speed are non-negotiable, this cutter delivers exceptional results, reducing cycle times and increasing productivity on the shop floor.

At the heart of this cutter's performance is its premium carbide insert technology. Unlike standard HSS bits that can dull quickly when generating heat in tough alloys, the carbide tips maintain their hardness at high temperatures, allowing for significantly faster feed rates and cutting speeds. This makes the 05D403 an indispensable tool for heavy-duty construction, rail maintenance, and equipment repair where downtime must be minimized. The specialized flute geometry is designed to evacuate chips efficiently, preventing clogging and heat buildup that can compromise the structural integrity of the workpiece or the tool itself.

The "Core Cut" annular design removes material only at the periphery of the hole, ejecting a solid slug at the end of the cut. This method requires less energy and force compared to twist drilling, which must convert the entire volume of the hole into chips. Consequently, this cutter places less strain on your magnetic drilling unit and allows for larger diameter holes to be drilled with smaller machines. With a 2-inch depth of cut capacity, it handles thick plates and structural members with ease, ensuring clean, burr-free holes that often require no secondary finishing operations.

Durability is a key feature of the Walter Carbide Core Cut series. The body of the cutter is constructed from high-quality steel that absorbs vibration, while the carbide teeth are brazed to withstand the shock of interrupted cuts often encountered on uneven surfaces. Whether you are drilling on a curved pipe or a rough casting, this tool maintains its centering and cutting accuracy. It is the ideal choice for professionals who demand reliability and longevity from their tooling investments.
