05F248 - Walter 48mm Carbide Tipped Annular Cutter 55mm Depth

Precision Engineering for Tough Materials

The Walter 05F248 Carbide Core Cut Annular Cutter represents the pinnacle of hole-making technology for industrial applications. Engineered by Walter Surface Technologies, this 48mm diameter cutter is specifically designed to overcome the limitations of standard High-Speed Steel (HSS) bits when facing challenging materials. The core of its performance lies in the premium tungsten carbide tips, which offer exceptional hardness and heat resistance. This allows the cutter to penetrate materials with high tensile strength, such as stainless steel, cast iron, and exotic alloys, without suffering from premature wear or thermal deformation.

With a cutting depth of 55mm, this tool is perfectly suited for drilling through thick plates, structural beams, and heavy-walled pipe. The geometry of the cutter is meticulously calculated to optimize chip flow. As the carbide tips shear the metal, the specially designed flutes rapidly evacuate the swarf, preventing clogging and reducing the torque load on the magnetic drill unit. This efficient cutting action not only speeds up the drilling process but also results in a superior surface finish inside the hole, often eliminating the need for secondary reaming or deburring operations.

The 05F248 is built to withstand the rigors of heavy industrial environments. Its robust body construction minimizes vibration, ensuring concentricity and accuracy even at the large 48mm diameter. For MRO professionals and machinists looking for reliability and precision, the Walter Carbide Core Cut series is the definitive choice for maximizing productivity and minimizing tooling costs over the long term.
