Iwaki, Japan – February, 2025 – Tungaloy Corporation (President: Satoshi Kinoshita, Head Office: Iwaki City, Fukushima Prefecture) announces the expansion of its TungMeister series, featuring a broader range of replaceable-head end mills with the advanced AH715 grade coating for extended tool life, improved surface finishes, and enhanced machining precision.
Challenges and Trends
In the automotive industry, construction machinery, general machining, and even in fields dealing with generator components, achieving high efficiency and stability in daily mass production processes is essential. For users of solid end mills in particular, extending tool life remains a critical challenge. Frequent tool wear and replacement not only reduce productivity but also increase cost burdens, driving a strong demand across the market for enhanced durability.
Additionally, with conventional end mill products, multiple passes in the Z-axis direction to machine walls can result in step marks at the pass junctions. This issue significantly affects the finish quality and precision of the machined surface, often necessitating additional corrective work in subsequent processes. Addressing these challenges and achieving higher-quality, more efficient machining are highly anticipated across many manufacturing sites.
Product Overview
TungMeister is Tungaloy’s high-efficiency exchangeable head end mill series. It offers flexibility with over 45 head shape options and a wide size range from 5mm to 32mm in diameter. Made from high-performance shank materials, it meets various machining needs and delivers exceptional productivity.
Benefits and Features
Feature 1: Simple and Quick Tool Replacement
The TUNGMEISTER system adopts a design where the cutting edge and shank are separated, allowing the head to be attached to the shank.
Eliminates the need for managing overhang length during tool replacement, significantly reducing tool replacement time.
Reduces machine downtime and boosts production efficiency.
Feature 2: Superior Tool Life with “Triple Nano Technology” Coating
The AH715 utilizes a “Triple Nano Technology” coating, which incorporates Nano multilayer film technology.
Provides outstanding tool life compared to existing and competing grades in the machining of various materials.
Extended tool life reduces tool replacement frequency, contributing to cost reduction and improved productivity.
Feature 3: Enhanced Surface Finish Quality
The newly expanded VEH-type square head features a design with an R added to the rear edge of the cutting blade.
Smoothly connects paths in the Z-axis direction, reducing step marks at the connection points.
This results in improved surface finish quality and achieves high-precision machining outcomes.
