DNMG110408 T9235 — DNMG turning insert by Tungaloy, 55° rhombic

The DNMG110408 T9235 is an ISO rhombic, double-sided indexable insert designed for external and internal turning, offering a robust solution where interrupted cuts and unstable setups demand higher toughness.

• CVD-coated carbide grade T9235
• ISO DNMG 110408 rhombic insert
• Double-sided chipbreaker for economy
• Cylindrical hole for secure clamping

Durable grade for unstable and interrupted turning

The CVD-coated carbide composition of the insert, specified as T9235, delivers increased toughness that reduces edge chipping in interrupted cuts and under unstable conditions. This translates into a measurable improvement in process reliability: the tougher substrate tolerates more shock without catastrophic edge failure, while the coating provides enhanced wear resistance and lower friction at the cutting zone. For operations in steel where cutting speed is conservative but stability is limited, the grading and coating combination supports longer effective tool life and steadier production.

Geometry that balances versatility and secure clamping

The rhombic plate form with a 55° cutting angle and a 0.8 mm corner radius offers a balance between strength at the cutting edge and surface finish capabilities; smaller radii favour finer finishes while contributing to lower cutting forces. The insert is double-sided, enabling economical index changes, and features a cylindrical hole for positive, repeatable clamping. As an ISO-form insert, compatibility with suitable external holders is determined by form, tolerance class, fastening method, size and thickness, which ensures predictable interchangeability across standard toolholder systems.

Practical guidance for application and optimisation

Intended primarily for turning of steel under less aggressive cutting speeds, the insert’s design promotes reliable chip control when matched with the correct chipbreaker and process parameters. The double-sided chipbreaker supports two usable cutting edges per index, reducing tooling costs per finished part. Selection of the precise chipbreaker variant and cutting data should follow the material grade, workpiece rigidity and machining stability; in marginal setups, favour lower feeds and conservative depths of cut to exploit the grade’s shock resistance while maintaining consistent surface quality. For assembly, use the compatible clamping set, underlay and replacement screws specified for ISO DNMG formats.

FAQ

Which materials is this insert best suited for?
The Tungaloy DNMG110408 T9235 insert is formulated primarily for machining steel; the T9235 grade provides toughness suitable for unstable conditions and interrupted cuts in steel applications.

Can the insert be used for both external and internal turning?
Yes, the ISO rhombic geometry and the cylindrical clamping hole make the insert suitable for both external and internal turning when used with the correct holder and mounting accessories.

How does the corner radius affect surface finish and strength?
A 0.8 mm corner radius gives a compromise between edge strength and surface finish; it improves edge robustness for semi-finishing operations while still allowing acceptable surface quality at typical turning feeds.

Is the DNMG110408 compatible with standard DNMG toolholders?
The DNMG110408 conforms to ISO geometry, so compatibility depends on matching the insert form, clearance angle, tolerance class, fastening and thickness to the holder specifications.

Are both sides of the insert usable?
Yes, the insert is double-sided, offering multiple cutting edges per plate to improve cost-efficiency and reduce changeover frequency.
