DNMG 150404 T9235 turning insert — CVD-coated carbide, double-sided chipbreaker (Tungaloy)

DNMG150404 T9235 is an indexable turning insert engineered for stable chip control and reliable performance in steel turning operations

• CVD-coated carbide for tough steel cuts
• Double-sided chipbreaker for consistent chips
• Rhombic DNMG shape with 55° cutting angle
• 0.4 mm corner radius for reliable edge strength

Consistent chip control for demanding steel turning

The CVD-coated carbide T9235 grade is formulated as a tougher cutting material for machining steel under lower cutting speeds and in less stable or interrupted cutting conditions. As a consequence, the insert provides improved wear resistance where shock and varying chiploads occur. The double-sided chipbreaker supports predictable chip formation and evacuation, reducing downtime for indexing and helping to maintain steady cycle times. This combination enhances process stability, which translates into more predictable batch output and fewer unplanned tool changes.

Design features that simplify holder selection and setup

The DNMG geometry (rhombic form with a 55° cutting angle) and the 0° relief geometry are standardised to fit ISO-compatible holders, but compatibility is ultimately determined by form, relief angle, tolerance class, fastening method, size and thickness. The insert has a 0.4 mm corner radius and a plate thickness of 4.76 mm, with a cylindrical mounting hole for positive clamping. Specifying the matching external holder, shim/clamp set and replacement screws ensures correct seat and secure fastening, avoiding runout and chatter while preserving surface finish quality.

Economical operation and predictable lifetime in production

As an indexable turning solution, the insert’s double-sided design supports multiple indexing positions, delivering a favourable cost-per-edge compared with brazed or solid tools. The rhombic DNMG form allows versatile use for both external and internal turning when used with the appropriate boring bar or holder. Where interrupted cuts or unstable setups are unavoidable, the tougher grade and chip control reduce catastrophic edge failure, increasing cumulative cutting time between regrinds or replacements. For those seeking improved throughput and lower tooling cost over time, this insert offers a pragmatic balance of robustness and efficiency.

FAQ

Which materials is this insert intended for?
The DNMG150404 T9235 insert is a tougher CVD-coated carbide grade optimised for machining steel, especially effective at lower cutting speeds and under interrupted or unstable cutting conditions.

How does the double-sided chipbreaker affect tool life?
A double-sided chipbreaker provides multiple usable cutting edges and consistent chip control, allowing for cost-efficient indexing and extended cumulative cutting time before replacement of the insert.

How is holder compatibility ensured?
Compatibility depends on matching the insert form, relief angle, tolerance class, fastening method, size and thickness; selecting an ISO-compatible DNMG holder with the correct clamp and shim set ensures proper seating and performance with the DNMG150404 T9235.

What components are required to build a functional system?
A complete system comprises the ISO insert, a suitable external holder or boring bar, a matching underlay/clamp set and replacement screws to secure the insert correctly.

Can this insert be used for internal turning operations?
Yes; the geometry and hole style permit use in both external and internal turning when combined with the appropriate boring bar and holder configuration.
