DNMG 150412 T9225 turning insert — Tungaloy (CVD-coated carbide, 55°)

A DNMG150412 T9225 ISO turning insert designed for robust medium-to-heavy steel turning, offering consistent chip control and repeatable edge life in variable engagement conditions

• DNMG ISO 55° rhombic geometry
• CVD-coated carbide grade T9225
• 1.2 mm corner radius for strength
• Double-sided insert with cylindrical hole

Consistent productivity and predictable tool life for turning

The rhombic 55° geometry combined with the T9225 CVD-coated carbide delivers a reliable balance between toughness and wear resistance, especially for interrupted or variable cuts. This combination reduces unplanned stops by improving edge stability and heat resistance during extended cycles. The measurable advantage is predictable tool life under mixed engagement, which supports planning for tool changes and reduces setup variability on batch and serial production lines.

Secure clamping and ISO compatibility for safe operation

Compatibility depends on matching form, relief angle, tolerance class, fixing method, size and thickness to the chosen holder. The insert is double-sided and supplied with a cylindrical centre hole, enabling secure seating and positive clamping in standard ISO indexable holders and boring bars. Correct seat selection and torque-controlled fastening minimise the risk of movement under load and maintain concentricity, translating directly into repeatable part tolerances and fewer rejects.

Material and coating explained: why T9225 counts

The T9225 designation denotes a CVD-coated carbide grade optimised for demanding steel applications. The chemical vapour deposition layer improves thermal stability and wear resistance, while the carbide substrate retains toughness. For medium-to-heavy steel turning this means improved resistance to flank wear and crater formation, particularly where cutting conditions vary. In plain terms: the coating extends cutting performance at elevated temperatures while the substrate prevents premature chipping in interrupted cuts.

Geometry, corner radius and chip control for quality surfaces

The 1.2 mm corner radius provides a compromise between edge strength and surface finish; it supports higher feedrates with lower risk of edge failure compared with sharper radii. The insert’s double-sided design offers two cutting edges per side, increasing economical indexability. Choose the appropriate chipbreaker and grade to match the stability of the setup and the steel grade being machined to obtain consistent surface quality and reduced secondary operations.

FAQ

What materials is this insert suited for?
The DNMG150412 T9225 insert is optimised for medium-to-heavy steel turning; the T9225 CVD-coated carbide offers improved wear resistance and toughness for variable cutting conditions.

How many usable edges are available on the insert?
As a double-sided rhombic insert with a central hole, the DNMG150412 provides multiple indexable cutting edges, allowing rotation to fresh edges to extend overall tool life.

Does the insert fit standard ISO holders?
Compatibility is determined by form, relief angle, tolerance class, fixing method, size and thickness; DNMG150412 follows ISO dimensions and seats in matching DNMG holders when clamped correctly.

What benefit does the 1.2 mm corner radius provide?
A 1.2 mm radius increases edge strength and permits higher feeds with reduced chipping risk, supporting more productive cutting in less stable or interrupted operations.

Why choose the T9225 grade over other coatings?
T9225 combines a wear-resistant CVD layer with a tough carbide core, giving balanced performance for demanding steel machining where intermittent cuts and changing engagement occur.
