05F239 - Walter Carbide Core Cut Annular Cutter 39mm x 55mm Depth

High-Performance Carbide Annular Cutter for Hardened Metals

The Walter 05F239 Carbide Core Cut is a premium-grade annular cutter engineered for the most demanding industrial drilling applications. Featuring a 39mm diameter and a 55mm depth of cut, this tool is specifically designed to tackle tough, abrasive materials that typically degrade standard High-Speed Steel (HSS) cutters. By utilizing extra-hard carbide inserts, Walter has created a cutter that maintains its cutting edge longer, even when processing stainless steel, cast iron, and other hard alloys. This durability translates directly to reduced downtime for tool changes and lower cost-per-hole in high-volume production environments.

The geometry of the Carbide Core Cut series is optimized for efficiency. A specialized flute and body design ensures rapid chip evacuation, which is critical when drilling deep holes in thick materials. This design minimizes heat generation—a common cause of premature tool failure—and allows for higher feed rates. Industrial operators can expect precise, burr-free holes with excellent surface finish, reducing the need for secondary finishing operations. Whether used in a workshop setting or for on-site maintenance with a magnetic drilling unit, this cutter delivers consistent, reliable performance.

Furthermore, the robust construction of the 05F239 allows it to handle challenging drilling conditions, such as entering curved surfaces or drilling through uneven layers, without wandering or breaking. It is an essential tool for MRO professionals and fabricators who require precision and speed when working with structural steel, rail, or heavy machinery components. The integration of advanced carbide technology ensures that this cutter stands as a superior choice for modern metalworking challenges.
