05F139 - Walter 39mm Carbide Tipped Annular Cutter 30mm Depth

Precision Drilling for Industrial Applications

The Walter 05F139 Carbide Core Cut Annular Cutter is a high-performance tooling solution designed for industrial environments where precision and speed are paramount. With a 39mm diameter and 30mm depth of cut, this cutter is engineered to tackle the most challenging materials found in MRO and heavy manufacturing sectors. Unlike standard High-Speed Steel (HSS) bits, the Carbide Core Cut series utilizes premium carbide inserts that maintain their hardness even at high temperatures, allowing for aggressive feed rates without compromising the integrity of the tool.

This cutter is particularly effective on hard, abrasive, or uneven materials such as stainless steel, cast iron, and specialized alloys. The body of the cutter features a sophisticated flute design that rapidly evacuates chips, preventing heat buildup and binding. For facility maintenance teams and machinists, this means less downtime for tool changes and more consistent hole quality. Whether you are drilling on-site with a portable magnetic drill or in a workshop setting, the Walter Carbide Core Cut delivers reliable, burr-free results.

Durability is a key feature of the 05F139. The carbide tips are brazed securely to the cutter body, ensuring they withstand the shock and vibration of heavy-duty drilling. This makes it an excellent choice for structural steel work, rail maintenance, and large-scale equipment repair. By reducing the effort required to drill through tough metals, this tool reduces operator fatigue and increases overall productivity.
