05D748 - Walter Carbide Tipped Annular Cutter 4 Inch x 3 Inch Depth

High-Performance Drilling for Tough Materials

The Walter Carbide Core Cut annular cutter (SKU: 05D748) represents the pinnacle of hole-making technology for industrial applications. Engineered specifically to tackle the most abrasive and hard-to-cut materials, this 4-inch diameter cutter with a 3-inch depth of cut is an essential tool for heavy fabrication, structural steelwork, and maintenance operations. Unlike traditional High-Speed Steel (HSS) cutters that can struggle or burn out when facing hardened alloys, the Carbide Core Cut series utilizes premium carbide inserts that maintain their cutting edge even under extreme thermal stress.

Precision is paramount in industrial environments, and Walter has designed this cutter to deliver accurate, round holes with exceptional surface finish. The specialized flute design promotes efficient chip ejection, which is critical when drilling deep 3-inch holes to prevent binding and overheating. This efficiency allows operators to run their magnetic drilling units at higher speeds and feed rates, significantly reducing cycle times and increasing overall shop throughput. Whether you are working with stainless steel, cast iron, or complex composite materials, this cutter provides the aggressive penetration needed without sacrificing tool life.

Durability is a core feature of the 05D748. The carbide tips are brazed using advanced techniques to ensure they withstand the shock and torque associated with large-diameter drilling. This makes the cutter particularly effective for on-site repairs where equipment downtime must be minimized. By choosing Walter's carbide technology, procurement managers and tool crib supervisors can reduce the frequency of tool replacements, ultimately lowering the cost per hole. This cutter is compatible with standard magnetic drills, making it a versatile addition to any professional tool inventory focused on efficiency and reliability.

In summary, the Walter Carbide Core Cut is not just a drill bit; it is a productivity solution for the toughest machining challenges. Its ability to handle uneven surfaces and resist wear in abrasive environments makes it the superior choice for professionals demanding the highest quality results in their metalworking projects.
