05F149 - Walter 49mm Carbide Tipped Annular Cutter 30mm Depth

Precision Drilling for Hardened Alloys

The Walter 05F149 49mm x 30mm Carbide Core Cut is a high-performance annular cutter engineered for the most demanding industrial drilling applications. Unlike standard High-Speed Steel (HSS) cutters, this tool utilizes premium tungsten carbide tips, significantly increasing hardness and heat resistance. This composition makes it the superior choice for machining tough, abrasive materials such as stainless steel, cast iron, and resilient high-tensile alloys. The cutter is designed to maintain its cutting edge longer, ensuring consistent hole geometry and reducing the frequency of tool replacements in high-volume production environments.

Technically, the Carbide Core Cut series features a sophisticated flute design that optimizes chip evacuation. Efficient chip removal is critical when drilling deep or large-diameter holes to prevent binding and heat accumulation, which can work-harden the material. The 49mm diameter and 30mm depth of cut provide substantial capacity for structural steelwork and heavy machinery fabrication. By allowing for higher rotational speeds and aggressive feed rates, this cutter improves overall operational efficiency, reducing cycle times per hole while minimizing the mechanical load on the drilling unit.

Furthermore, the structural integrity of the carbide inserts allows for drilling on non-standard surfaces. Whether the workpiece is curved, uneven, or has a rough surface finish, the Walter 05F149 engages cleanly without wandering, ensuring precise hole placement. This stability is essential for maintaining tolerances in complex assemblies. For MRO professionals seeking a reliable solution for hard-metal drilling that outperforms traditional tooling, this carbide cutter delivers measurable improvements in productivity and finish quality.
