05D105 - Walter 1-5/16 Inch Carbide Tipped Annular Cutter 1.5 Inch Depth

Technical Overview: Walter 05D105 Carbide Core Cut

The Walter 05D105 is a high-performance annular cutter belonging to the renowned Carbide Core Cut series, engineered specifically for industrial drilling applications involving challenging metallurgical compositions. This cutter features a precise diameter of 1-5/16 inches and a cutting depth capacity of 1.5 inches, making it a versatile tool for structural fabrication and heavy-duty maintenance operations. Unlike traditional High-Speed Steel (HSS) cutters, this unit utilizes premium-grade carbide inserts brazed onto a hardened steel body. This construction allows the tool to maintain hardness and cutting edge integrity at significantly higher temperatures, a critical factor when machining materials with low thermal conductivity such as stainless steel.

The geometry of the 05D105 is optimized for aggressive material removal. The flute design is engineered to maximize chip evacuation, preventing heat buildup and work hardening of the substrate material—a common issue when drilling austenitic stainless steels. The carbide tips are precision-ground to ensure concentricity and reduce vibration during the drilling process. This results in holes with superior surface finish and dimensional accuracy, often eliminating the need for secondary reaming or deburring operations. The cutter is designed to withstand the high torque and feed pressures associated with magnetic drilling units, ensuring stability even when drilling into uneven or curved surfaces.

In terms of operational parameters, the Walter Carbide Core Cut series allows for substantially higher surface feet per minute (SFM) compared to HSS alternatives. This efficiency translates to reduced cycle times per hole. The tool is compatible with a wide range of ferrous and non-ferrous metals, including cast iron, carbon steel, structural steel, and various hard alloys. Its robust construction makes it particularly suitable for MRO (Maintenance, Repair, and Operations) environments where tool reliability is paramount. Operators can expect consistent performance and extended tool life, reducing the frequency of tool changes and associated downtime.

The 05D105 is an essential component for fabrication shops and field service teams requiring reliable hole-making capabilities in tough materials. Its ability to handle the thermal and mechanical stresses of drilling hard alloys ensures that it remains a cost-effective solution for high-volume and critical drilling tasks.
