05D736 - Walter 3-1/4 Inch Carbide Tipped Annular Cutter 3 Inch Depth

Precision Engineering for Tough Alloys

The Walter 05D736 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for industrial applications involving difficult-to-machine materials. Engineered with a substantial 3-1/4 inch diameter and a 3-inch depth of cut, this tool is specifically designed to overcome the limitations of traditional High-Speed Steel (HSS) cutters. The core innovation lies in its high-grade carbide inserts, which offer exceptional hardness and thermal stability. This allows the cutter to maintain its cutting edge even when subjected to the high heat generated during the machining of stainless steel, cast iron, and abrasive composites.

Structurally, the cutter features a proprietary flute and body design optimized for efficient chip evacuation. In deep hole drilling, chip packing is a common failure mode; Walter's design ensures that swarf is ejected rapidly, preventing heat buildup and binding. This geometry also contributes to the tool's stability, enabling it to engage with curved or irregular surfaces without the "walking" often associated with twist drills. For maintenance and repair operations (MRO) requiring precision holes in existing infrastructure, this stability is critical.

The Carbide Core Cut series is not merely a harder drill bit; it is a productivity solution. By removing material only at the periphery of the hole, it requires less energy and force than solid drilling, reducing wear on the magnetic drilling unit. The result is a clean, burr-free hole with tight tolerances, often eliminating the need for reaming or deburring. For fabrication shops dealing with high-tensile alloys or heavy structural components, the 05D736 provides a reliable, high-performance solution that maximizes machine uptime and cut quality.
