New Product | AT210A Cermet Grade for Small Parts: High Precision, High-Efficiency Machining

Driven by market demand and technological upgrading trends, cermet cutting tools, with their superior performance and cost-effectiveness, serve as an effective alternative to imported brands in mid-to-high-end machining applications, helping customers reduce procurement costs. Meanwhile, as modern machining evolves toward higher speed, higher precision and better surface quality, cermet materials have emerged as an ideal cutting tool solution: they address the wear-prone drawback of conventional cemented carbide inserts in finishing operations, while overcoming the high brittleness of pure ceramic inserts.

For the steel small parts machining sector, ACHTECK Tools expands its portfolio with the new AT210A grade. Combining gradient material technology with a composite nano-coating process, this grade is applied to precision ground turning inserts, delivering high-quality machined surfaces and enabling high-precision, high-efficiency machining.

Key Product Features

The AT210A retains its hardness even at elevated temperatures of 800–1000℃. Its oxidation resistance outperforms cemented carbide, reducing cutting heat-induced edge softening and making it ideal for high-speed machining.
It delivers exceptional resistance to diffusion wear and crater wear — two common wear modes in steel machining — significantly extending tool service life.
The low friction coefficient between cermet surfaces and metallic materials results in low cutting resistance and reduced built-up edge (BUE) formation. The composite nano-coating of the AT210A further lowers the friction coefficient.
Compared with pure ceramic inserts, the metallic phase in cermet improves toughness, enabling it to withstand moderate impact loads such as interrupted cutting.
