05D406 - Walter 1-3/8 Inch Carbide Tipped Annular Cutter 2 Inch Depth

Precision Engineering for Tough Materials

The Walter 05D406 Carbide Core Cut annular cutter is a premium industrial tool designed to address the challenges of drilling large diameter holes in materials with high tensile strength and abrasive properties. Unlike traditional High-Speed Steel (HSS) cutters, this unit utilizes high-grade carbide inserts that maintain their hardness at elevated temperatures, allowing for significantly higher surface feet per minute (SFM) during operation. This 1-3/8 inch diameter cutter features a 2-inch depth of cut, making it an essential component for structural fabrication, heavy machinery maintenance, and MRO operations involving thick plate or pipe.

The geometry of the Carbide Core Cut is engineered to optimize chip load and evacuation. The specialized flute design prevents chip packing, which is a common failure mode in deep hole drilling, particularly in gummy materials like certain grades of stainless steel or aluminum. By efficiently removing debris and reducing friction, the cutter minimizes thermal transfer to the workpiece, preserving the metallurgical integrity of the base material and extending the life of the tool. This makes it particularly effective for drilling cast iron, hard alloys, and uneven surfaces where shock loading might otherwise damage a standard bit.

For procurement and operations managers, the value proposition of the 05D406 lies in its efficiency and durability. The ability to drill faster with less down-pressure reduces operator fatigue and machine wear, while the extended tool life decreases the frequency of tool changes, ultimately lowering the total cost per hole. Whether utilized in a controlled shop environment or on-site with portable magnetic drilling units, this Walter cutter delivers consistent, burr-free performance that meets the rigorous standards of modern industrial fabrication.
