Iwaki, Japan – January, 2025 – Tungaloy Corporation (President: Satoshi Kinoshita, Head Office: Iwaki City, Fukushima Prefecture) announces the expansion of its SolidMeister series, featuring the new grade AH3005 for enhanced durability in machining high-hardness materials up to 65 HRC. The lineup now offers tool diameters from 0.3 to 6.0 mm, including versatile ball, 2-flute, 4-flute, and 6-flute square end mills, enabling high-efficiency machining and extended tool life across a wide range of applications.
Challenges and Trends
In the field of mold machining and high-hardness steel machining, numerous challenges related to tool life and machining efficiency are commonly observed. Particularly in the machining of high-hardness steel, tools experience severe wear, making it difficult to complete shape machining with a single end mill. Additionally, the conventional lineup of small-diameter end mills often falls short of meeting certain machining requirements, creating a demand for more options. Furthermore, even when using 4-flute end mills for finishing processes, machining efficiency does not sufficiently improve, making it challenging to maintain productivity. To address these challenges and market conditions, the development of higher-performance end mills capable of meeting diverse needs is strongly demanded by the market.
Product Overview
SolidMeister is a high-performance end mill ideal for precision-demanding fields such as mold machining, aerospace components, and turbine blades. It is designed to handle difficult-to-machine materials like steel, heat-resistant alloys, and titanium alloys. With cutting-edge technology, it delivers reduced machining time and enhanced productivity.
