05D740 - Walter 3-1/2 Inch Carbide Tipped Annular Cutter 3 Inch Depth

Precision Drilling for Hardened Alloys

The Walter 05D740 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for industrial applications. Designed with a substantial 3-1/2 inch diameter and a 3-inch depth of cut, this tool is engineered to tackle the most challenging materials that standard High-Speed Steel (HSS) cutters simply cannot handle. By utilizing premium tungsten carbide tips, Walter has created a cutter that maintains its cutting edge even under the high thermal stress generated when drilling stainless steel, cast iron, and other resilient alloys.

Efficiency is at the core of the 05D740's design. The specialized flute geometry is optimized for rapid chip evacuation, a critical factor when drilling deep holes in dense materials. This design reduces friction and heat buildup, allowing for significantly faster feed rates and reduced dwell time. For fabrication shops and industrial maintenance teams, this translates to lower cycle times and increased throughput. The carbide composition also provides the rigidity necessary to drill precise, burr-free holes, minimizing the need for secondary finishing operations.

Beyond its metallurgical advantages, the Walter Carbide Core Cut is built for versatility in difficult operating conditions. It excels in drilling uneven or curved surfaces, a common scenario in structural steel erection and heavy equipment repair. Where traditional twist drills might wander or bind, this annular cutter bites in cleanly and maintains concentricity throughout the cut. Whether utilized in a controlled workshop environment or on-site with a magnetic drilling unit, the 05D740 delivers consistent, high-performance results for heavy-duty boring operations.
