PCD/PCBN Integrated Touring Holder Reamer
With a focus on consistent quality based on the control of key reamer specifications—such as outer diameter and runout tolerance—our designs can accommodate high-precision requirements, including surface roughness, roundness, and concentricity, as well as high-speed feed rates. We meet our customers’ needs with a wide range of products, from standard specifications to value-added options.
Switching from the conventional straight-edge design to a design with a lead allows for a significant reduction in resistance, enabling high-speed feed. This contributes to improved productivity.


By adopting a unique, specially designed segmented blade configuration, we can suppress resonance vibrations and ensure stable roundness and cylindricity.
