05D309 - Walter 9/16" x 2" Carbide Tipped Annular Cutter

High-Performance Carbide Drilling for Tough Alloys

The Walter 05D309 Carbide Core Cut Annular Cutter is a premium industrial tool designed to tackle the most challenging drilling applications in the metalworking industry. Measuring 9/16 inches in diameter with a substantial 2-inch depth of cut, this cutter is engineered to penetrate hard materials that typically degrade standard High-Speed Steel (HSS) bits rapidly. By utilizing high-grade tungsten carbide tips, Walter has created a tool that maintains its cutting edge even under the high thermal stress generated when drilling stainless steel, cast iron, and other abrasive alloys.

Efficiency is at the core of the 05D309's design. The specialized flute geometry promotes rapid chip evacuation, which is critical when drilling deep holes to prevent binding and overheating. This design allows operators to run their magnetic drilling units at higher speeds and feed rates, significantly improving productivity on the shop floor. Whether you are working on structural steel erection, heavy equipment repair, or precision fabrication, the ability to drill clean, burr-free holes quickly translates to lower labor costs and reduced downtime.

One of the standout features of the Carbide Core Cut series is its versatility on uneven surfaces. Traditional drill bits often wander or break when engaging curved or irregular faces, but the robust construction of this carbide cutter ensures stability and precision from the moment of contact. It is particularly effective for on-site drilling tasks where conditions are less than ideal. The cutter is compatible with a wide range of magnetic drilling units, making it a flexible addition to any professional tool crib.

Durability is paramount in industrial environments, and the Walter 05D309 delivers with a long operational lifespan. The carbide inserts are brazed securely to the body, resisting the shock and vibration common in heavy-duty drilling. This resilience makes it an excellent choice for drilling through rust, scale, and composite materials without compromising the integrity of the hole. For professionals seeking a reliable, high-speed solution for large diameter holes in tough metals, the Walter Carbide Core Cut stands out as a superior choice.
