In high-feed machining operations, stability, rigidity and cost efficiency are essential for achieving consistent results and maximizing productivity. Addressing these demands, Tungaloy-NTK America Inc. has expanded its DoFeedTri cutter series, introducing additional tool body diameters to provide greater application flexibility while maintaining the performance advantages that define the platform.

The DoFeedTri series is engineered specifically for high-feed milling applications, where shallow depths of cut and high table feed rates demand exceptional rigidity and precision. At the core of the system is a robust cutter body designed to withstand aggressive cutting conditions while minimizing vibration. This high-rigidity construction enhances process stability, reduces deflection and supports predictable machining outcomes — particularly important in demanding production environments.

A defining feature of the DoFeedTri system is its double-sided insert design. Each insert provides six usable cutting edges, significantly improving cost efficiency by maximizing insert utilization before indexing or replacement is required. This design not only reduces tooling costs per edge but also supports sustained performance during extended production runs. The combination of a strong cutter body and durable insert geometry enables high metal removal rates without sacrificing surface integrity or tool life.

With the latest expansion, Tungaloy has broadened the available range of tool body diameters. This development gives manufacturers greater flexibility to align cutter size precisely with specific workpiece geometries and machining conditions. Selecting the correct diameter helps reduce unnecessary tool overhang, which can otherwise introduce instability and excessive cutting loads. By optimizing tool engagement, users can achieve smoother cutting action and enhanced overall performance.

Another benefit of the expanded diameter range is improved control over cutting accuracy. By matching tool size more closely to the material and operation, machinists can prevent inadvertent overcutting and maintain surface integrity. This level of precision is particularly valuable in industries where dimensional accuracy and repeatability are critical, such as aerospace, automotive and die and mold manufacturing.

The broader lineup also allows manufacturers to address applications that may previously have fallen outside the supported range. Whether working on smaller components requiring compact tooling or larger parts demanding increased cutter diameter for coverage and efficiency, the expanded DoFeedTri series provides more options to meet evolving production requirements.

According to Tungaloy, refining the diameter selection enhances process stability, extends tool life and delivers more predictable machining results — key advantages in high-feed operations where precision and repeatability directly impact productivity and profitability. By combining structural rigidity, cost-efficient insert technology and expanded dimensional flexibility, the DoFeedTri cutter series strengthens its position as a versatile and performance-driven solution for modern milling applications.
