05F148 - Walter 48mm Carbide Tipped Annular Cutter 30mm Depth

Precision Engineering for Tough Materials

The Walter 05F148 Carbide Core Cut annular cutter represents the pinnacle of drilling technology for industrial applications requiring large diameter holes in hardened materials. Engineered with a 48mm diameter and a 30mm cutting depth, this tool is specifically designed to overcome the limitations of traditional High-Speed Steel (HSS) cutters. The core advantage lies in its tungsten carbide tips, which provide exceptional hardness and thermal stability. This allows the cutter to maintain its cutting edge even when subjected to the high temperatures generated during the machining of abrasive materials like cast iron, stainless steel, and tough alloys.

The structural design of the 05F148 features a specialized flute geometry that optimizes chip flow. In deep hole drilling, chip evacuation is critical to preventing heat buildup and tool binding. Walter's design ensures that swarf is ejected efficiently, reducing the mechanical load on the magnetic drilling unit and allowing for higher feed rates. This efficiency translates to reduced cycle times and less wear on the machine motor. Furthermore, the carbide inserts are brazed using advanced techniques to ensure they withstand the shock and torque associated with heavy-duty drilling operations.

For MRO professionals and machinists, the consistency of the Walter Carbide Core Cut series is a significant asset. Unlike twist drills that require massive axial force and remove all material in the hole's volume, this annular cutter removes only the periphery, ejecting a solid slug. This method requires significantly less energy and results in a cleaner, more precise hole with superior surface finish. The 05F148 is an essential tool for fabrication shops dealing with structural steel, pipe fitting, and equipment repair where accuracy and tool longevity are non-negotiable.
