Tungaloy-NTK America Inc has expanded its DrillMeister exchangeable-head drill series with the introduction of new pre-thread drills that enable drilling and chamfering in a single operation. The latest addition is designed to simplify hole-making processes, reduce machining time, and improve productivity for manufacturers across a wide range of industries.
The new DrillMeister pre-thread drills are engineered for standard tap-size holes, allowing machine shops to complete drilling and chamfering in one pass instead of carrying out two separate operations. By eliminating the need for an additional chamfering step, manufacturers can reduce tool changes, minimise machine downtime, and improve overall production efficiency.
The solution supports commonly used tap sizes, including 3/8-inch, 7/16-inch, 1/2-inch, 9/16-inch, 5/8-inch, 3/4-inch, and 7/8-inch, making it suitable for a broad range of machining applications. For jobs requiring extended reach, Tungaloy also offers modular drill bodies with integrated chamfering capability, enabling reliable performance even in long-overhang applications.
The expanded DrillMeister range has been developed to help manufacturers optimise machining operations while maintaining high levels of accuracy and consistency. Combining multiple machining processes into a single operation not only shortens production cycles but also improves workflow by reducing setup time and machine interruptions.
DrillMeister is built around a flexible exchangeable-head system that allows one drill body to be used with different cutting heads, enabling manufacturers to adapt quickly to various machining requirements without replacing the complete tool. This modular design offers greater versatility while reducing tooling costs and inventory requirements.
The DrillMeister portfolio includes several specialised head options designed for different materials and machining conditions. These include the DMP general-purpose head, the DMC self-centering head for high-accuracy drilling, the DMF head for flat-bottom holes, the reinforced-edge DMH head for demanding applications, the DMM head for stainless steel and exotic alloys, and the DMN head for machining non-ferrous materials.
To enhance tool performance, Tungaloy offers the AH9130 grade across the DrillMeister series. The grade features an advanced nano-multilayer coating that provides high resistance to wear, oxidation, built-up edge formation, and tool fracture. The strong bond between the coating and carbide substrate helps prevent coating separation during machining, resulting in longer tool life and more stable cutting performance.
With the latest expansion of the DrillMeister family, Tungaloy continues to provide machining solutions that improve efficiency, reduce production costs, and support higher productivity. The new pre-thread drilling solution offers manufacturers a practical way to simplify operations while maintaining the precision, reliability, and durability required in today’s competitive manufacturing environment.
