Iwaki, Japan – October, 2026 – Tungaloy Corporation (President: Satoshi Kinoshita, Head Office: Iwaki City, Fukushima Prefecture) announces the expansion of its TungMeister series with the addition of the AH715 grade to its T-slot milling head lineup. As the first-choice general-purpose grade, AH715 offers excellent wear and chipping resistance. Combined with a wide variety of head geometries and shank options, it helps reduce setup time while achieving both high machining accuracy and long tool life.
Challenges and Trends
In the manufacturing of automotive components, tooling-related parts, and general machinery components, slot milling with T-slot cutters is an important machining process. Conventional HSS tools and brazed carbide T-slot cutters have faced challenges in terms of limited tool life. Frequent tool changes and maintenance during machining can negatively impact productivity and increase operating costs. As a result, demand has been growing for more durable and longer-lasting cutting tools. To address these challenges, Tungaloy continues to develop innovative solutions that help customers improve productivity and reduce manufacturing costs on the shop floor.
Product Overview
TungMeister is a head-changeable end mill series designed to deliver high-precision and high-efficiency machining. The lineup includes more than 50 head geometries and a wide variety of shank materials, covering tool diameters from 5 mm to 32 mm. With over 25,000 possible head and shank combinations, the series supports a broad range of machining applications. The system enables quick and easy tool changes with excellent repeatability, reducing setup time while maintaining stable cutting performance.
