Tungaloy Expands DoFeedTri High-Feed Cutter Series with New Tool Diameters for Greater Machining Flexibility!

Tungaloy-NTK America, Inc. has expanded its DoFeedTri high-feed cutter series, introducing a wider range of tool body diameters designed to help manufacturers fine-tune their machining setups for optimal performance. This expansion enhances flexibility in matching tool geometry to specific application requirements, particularly in roughing and ramping operations where tool size plays a crucial role in maintaining accuracy and surface integrity.

When machining tough materials such as stainless steel, the use of an overly large cutter can remove more stock than intended, even when a finishing allowance is planned. This often leads to compromised part quality and added rework in downstream operations. Recognizing these challenges, Tungaloy has tailored the DoFeedTri series to give machinists the ability to select the ideal tool diameter for each unique workpiece and cutting condition.

At the heart of the DoFeedTri series is a high-rigidity cutter body engineered to withstand the demanding forces of high-feed machining. It is paired with double-sided inserts offering six cutting edges, maximizing productivity while keeping tooling costs under control.

The expanded range of tool diameters delivers several key advantages:

• Optimized tool selection: Machinists can now choose cutter sizes precisely matched to workpiece geometry and machining conditions, reducing unnecessary overhang and minimizing cutting loads.
• Improved surface quality: By aligning tool size more accurately with the operation, users can prevent overcutting and maintain superior surface integrity.
• Broader application coverage: The new diameter options open up capabilities for a wider variety of machining scenarios that were previously unsupported.

According to Tungaloy, this enhanced range promotes greater process stability, longer tool life, and more predictable machining outcomes—particularly in high-feed applications where consistency and repeatability are critical.

With this expansion, the DoFeedTri series reinforces its position as a versatile and cost-effective solution for high-efficiency metal removal, empowering manufacturers to achieve faster cycle times, tighter tolerances, and smoother workflow integration across diverse industries.
