05H275 - Walter 27.5mm x 55mm Carbide Tipped Annular Cutter

Precision Engineered Carbide Annular Cutter

The Walter 05H275 is a high-performance 27.5mm Carbide Core Cut annular cutter designed for industrial metalworking applications requiring precision and speed. Engineered by Walter Surface Technologies, this cutter features premium carbide tips (TCT) that are brazed onto a tough alloy body. This construction allows the tool to cut through difficult materials such as stainless steel, cast iron, and hard alloys that would typically dull standard High-Speed Steel (HSS) bits rapidly. The 55mm depth of cut capability makes this tool particularly versatile, allowing operators to drill through thick plates, structural beams, and pipe walls in a single pass.

The geometry of the Walter Carbide Core Cut is optimized for efficient chip removal. As the cutter rotates, the specialized flute design ejects swarf quickly, preventing heat accumulation that can damage the workpiece or the tool itself. This thermal management is critical when working with work-hardening materials like stainless steel. The cutter utilizes a standard Weldon shank, ensuring secure fitment and torque transmission in a wide variety of magnetic drilling machines. By cutting only the periphery of the hole and ejecting a solid slug, this tool requires less energy and force than solid twist drills, resulting in less wear on the machine motor and reduced operator fatigue.

Durability is a hallmark of the Walter Core Cut series. The carbide grades are selected for their balance of hardness and toughness, resisting micro-chipping during the initial entry into the material. This reliability ensures consistent hole tolerances over the life of the cutter, reducing the need for secondary reaming or deburring operations. For MRO professionals and fabricators, the 05H275 represents a cost-effective solution for high-volume hole making where accuracy and cycle time are paramount.
