Iwaki, Japan – April, 2024 – Tungaloy Corporation (President: Satoshi Kinoshita, Head Office: Iwaki City, Fukushima Prefecture) announces the expansion of its DrillMeister series, now featuring head-changeable drills from 4.0 mm to 8.4 mm in diameter with 3xD drilling depth, compatible with TinyMiniTurn sleeves for automatic lathes.

Challenges and Trends
In drilling operations using automatic lathes, the tool mounting diameter is restricted, making it common to use sleeves for tool installation. However, with conventional sleeves, the drill overhang must be readjusted during tool changes. This adjustment process is difficult in the limited space inside the machine, leading to poor workability and decreased productivity. These challenges and market conditions have created a demand for more efficient and user-friendly tool solutions.
