Tungaloy Expands PVD Grade AH3225 to Broader Milling Applications
November 1, 2025
Tungaloy Corporation has expanded its AH3225 PVD-coated grade, now available across a wider range of milling tools including high-feed cutters (MillQuadFeed), face milling cutters (DoOcto), shoulder milling cutters (TungTriShred), and ISO insert geometries such as SDKN42 and TEEN32.
"Across sectors such as general machining, automotive parts manufacturing, die and mold, and heavy electrical and industrial machinery, manufacturers are under increasing pressure to improve machining efficiency and extend tool life-particularly in ISO P steel applications," said a company spokesperson. "In these high-speed, high-load conditions, traditional grades often wear rapidly, leading to unstable performance and increased production costs."
The spokesperson continued: "To address these challenges, Tungaloy developed AH3225 with a proprietary Triple Nano Coating, offering an excellent combination of wear resistance, fracture toughness, and oxidation resistance. This technology offers long tool life, minimizes dimensional variation, and delivers consistent machining quality even under demanding conditions."
Key benefits and features:
- High resistance to crater and flank wear for extended tool life
- Reduced frequency of tool changes and stable machining across long production runs
- Maintains surface quality and tight tolerances over time
- Enables faster cutting speeds and feedrates without compromising tool integrity
- Suited for high-feed and high-speed applications, reducing cycle times and overall machining costs
- Available across popular milling tool families: MillQuadFeed, DoOcto, and TungTriShred
- Compatible with ISO insert styles (SDKN42, TEEN32), offering flexible tooling solutions tailored to varied machining environments.
