05D518 - Walter 2-1/2 Inch TCT Annular Cutter 1-1/2 Depth Weldon Shank

Precision Engineering for Tough Materials

The Walter 05D518 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for industrial applications. Designed with premium tungsten carbide tips (TCT), this 2-1/2 inch diameter cutter is engineered to overcome the limitations of traditional High Speed Steel (HSS) bits. When faced with abrasive materials, high-tensile alloys, or hardened metals, standard cutters often fail due to excessive heat generation and edge degradation. The Carbide Core Cut series addresses these challenges with a specialized metallurgical composition and advanced geometry that maintains hardness even at elevated cutting temperatures.

This specific unit features a 1-1/2 inch depth of cut, making it versatile for drilling through thick plate, structural beams, and heavy-walled pipe. The 3/4 inch Weldon shank is the industry standard, ensuring seamless integration with a wide array of magnetic drilling units. The cutter's design incorporates a sophisticated flute profile that accelerates chip removal. Efficient chip evacuation is critical in large-diameter drilling to prevent recutting of chips, which can damage the cutting edges and mar the surface finish of the workpiece. By clearing debris effectively, the Walter 05D518 maintains a cooler cutting zone and extends tool life.

Furthermore, the carbide inserts are precision-ground to handle interrupted cuts and uneven surfaces. Whether drilling into cast iron housings or overlapping existing holes for slotting applications, the rigid body and hard cutting tips resist deflection and wandering. This stability ensures that every hole meets tight tolerance specifications, reducing the need for reaming or secondary finishing operations. For MRO professionals and fabricators demanding reliability and speed in the most challenging materials, the Walter Carbide Core Cut is the definitive solution.
