Iwaki, Japan – May, 2026 – Tungaloy Corporation (President: Satoshi Kinoshita, Head Office: Iwaki City, Fukushima Prefecture) announces the expansion of its TungMeister series with new cylindrical blanks for exchangeable-head tools, enabling more flexible special tool design and enhanced cost efficiency.
Challenges and Trends
In recent years, driven by the rising cost of carbide materials, users of specially shaped solid end mills have increasingly sought to achieve both reduced production costs and extended tool life. As a result, the use of exchangeable head tools has been expanding, and the demand for blanks has been rapidly increasing.
With conventional solid end mills, the overall tool length is limited by the material length, making it difficult to handle deep machining or long overhang applications. In addition, there is a growing need to shorten setup and tool change times even for special-shaped tools. Consequently, production sites are demanding more flexible and efficient tool solutions.
Product Overview
TungMeister is an exchangeable-head end mill series designed to deliver high precision and productivity. With more than 45 head geometries and a wide range of materials available, it covers diameters from 5 to 32 mm. The easy head replacement reduces setup time while maintaining stable cutting performance.
Benefits and Features
Feature 1: High Design Flexibility with a Wide Range of Diameters
– Expanded cylindrical blank lineup from ø6 to ø20 to meet diverse machining needs.
-Enables the design of specialized tools optimized for workpiece sizes ranging from small to medium diameters.
– Provides flexibility in designing specialized tool geometries, achieving optimal cutting performance.
Feature 2: High Versatility through Combination with Standard Shanks
– Only the head section requires a special geometry, while the shank can utilize standard products.
– A wide range of shank options allows selection of the ideal overhang length, supporting deep and long‑reach machining.
– Utilizing standard shanks achieves both cost efficiency and shorter delivery lead times.
Feature 3: Reduced Setup Time with Exchangeable Head System
– Even specialized tools adopt the TungMeister exchangeable‑head structure.
– When the tool is worn, only the head needs to be replaced, greatly reducing setup time.
– Improves production line uptime and enhances maintenance efficiency.
