DNMG150404 T9225 Tungaloy indexable insert — Turning (ISO rhombic, 55°)

The DNMG150404 T9225 is an ISO rhombic indexable insert engineered for medium to heavy turning operations, providing a rugged, CVD-coated carbide grade for stable chip formation and extended tool life.

• CVD-coated carbide Grade T9225
• ISO rhombic DNMG 55° geometry
• Double-sided chipbreaker design
• Cylindrical hole for secure clamping

Consistent performance with a universal carbide grade

The insert is built from CVD‑coated carbide, a coating process that deposits hard ceramic layers onto the carbide substrate to enhance wear resistance and thermal stability. The T9225 designation denotes a robust universal grade intended for medium to heavy steel turning, particularly where variable engagement or light interruptions in the cut demand increased toughness. In practical terms, this means longer intervals between indexings and fewer tool changes, which supports efficient production flows and predictable component quality. The composition and coating together balance hardness and fracture resistance to suit a wide range of steels and typical workshop conditions.

Stable clamping and geometry for precise cutting

The ISO rhombic DNMG format with a 55° lead angle combines approach accessibility with edge strength, making it suitable for external and internal turning tasks. The insert features a 0° clearance angle and a cylindrical hole, ensuring secure, concentric clamping in standard holders and boring bars; compatibility depends on holder form, tolerance class and plate thickness. The double-sided chipbreaker contributes to repeatable chip control and predictable forces during the cut. These design elements reduce vibration and improve surface integrity, which is particularly valuable when machining components that require consistent dimensional accuracy.

Workshop advantages and system compatibility

Using an ISO-indexable insert like this one streamlines tooling logistics: the double-sided design offers multiple usable edges, reducing inventory and cost per edge compared with single-edge solutions. The rhombic shape and standard size mean easy replacement within an existing ISO tooling system; the 15 mm plate size and 4.76 mm thickness are compatible with common holders, and the insert is intended to work with appropriate underplates, clamping kits and replacement screws as part of the system. For interrupted cuts or variable feed conditions, the grade’s toughness and the chipbreaker geometry improve process security and extend effective tool life, supporting reliable, repeatable production.

FAQ

What materials is this insert best suited for?
The Tungaloy DNMG150404 T9225 insert is optimised for medium to heavy steel machining and performs well under variable engagement and light interruptions thanks to the tough T9225 grade.

How many usable cutting edges are available?
The double-sided chipbreaker provides multiple usable edges; reversing and re-indexing the insert extends the total number of cuts per insert and reduces tooling cost per edge.

Which holders are compatible with this DNMG insert?
Compatibility is dictated by ISO form, clearance angle, tolerance class, clamping method, size and thickness; the DNMG150404 fits standard ISO rhombic external holders and boring bars designed for 15 mm inserts.

What benefit does the CVD coating bring?
The CVD-coated carbide increases wear resistance and thermal stability at elevated cutting speeds, improving tool life and maintaining edge integrity in demanding turning operations.

What are the exact identification codes for ordering?
Relevant identifiers are SKU 6944688-Tungaloy and manufacturer article number 6944688; the manufacturer SKU is TUN6944688 and the ISO designation is DNMG150404.
