Iwaki, Japan – December 2025 – Tungaloy Corporation (President: Satoshi Kinoshita, Head Office: Iwaki City, Fukushima Prefecture) announces the expansion of its BoreMeister series, now featuring a ø80 anti-vibration bar for large-diameter deep hole machining and PSC adapters (C4 L/D=7, C5–C6 L/D=9) for enhanced machine compatibility and stable cutting performance.
Challenges and Trends
In industries such as aerospace, general machinery, and automotive components, deep hole machining is frequently required. However, this type of machining often faces challenges such as poor chip evacuation, tool chatter, and dimensional inconsistencies, making it difficult to maintain stable productivity and quality. Especially in environments where high precision and high efficiency are demanded, there is a strong need for machining tools that can effectively address these issues.
Product Overview
BoreMeister is a high-performance anti-vibration tooling series designed for internal turning operations. With a wide variety of interchangeable heads and shank combinations, it supports a broad range of machining applications including grooving, threading, and internal turning. Capable of handling overhang lengths from 3D to 10D, BOREMEISTER ensures high precision and productivity even in deep hole machining.
