DNMG150408 T9235 — ISO turning insert for unstable and interrupted turning, Tungaloy

The DNMG150408 T9235 is an ISO‑standard rhombic turning insert intended for external and internal turning where interrupted cuts or reduced machine stability require a tougher grade and reliable chip control.

• CVD-coated carbide grade T9235
• ISO-standard rhombic DNMG geometry
• 0.8 mm corner radius for robust cutting
• Double-sided chipbreaker, cylindrical hole

Increased process reliability for interrupted and unstable cuts

The CVD-coated cemented carbide substrate of this insert delivers pronounced toughness, which is beneficial when machining under unstable conditions or performing interrupted cuts. The T9235 grade is formulated for lower cutting speeds where edge strength and resistance to chipping are priorities. By choosing a tougher grade rather than a harder, more brittle alternative, the risk of premature edge failure is minimised and tool life becomes more predictable. This translates into fewer unscheduled insert changes and a steadier production flow.

Geometry and clamping designed for predictable handling and chip control

The ISO DNMG form with a rhombic outline and a 55° cutting angle provides a widely compatible platform for many external holders. The insert is double-sided, offering two usable edges per side, and is supplied with a cylindrical hole, ensuring positive location in standard clamping systems. The 0.8 mm corner radius balances edge strength with obtainable surface finish. Compatibility with a specific holder is determined by form, relief angle, tolerance class, fastening, size and thickness; these parameters should be checked against the toolholder documentation before assembly to guarantee correct seating and repeatable results.

Rapid changeover and economical operation for production environments

A double-sided chipbreaker lowers set-up times because each indexation restores a prepared cutting edge without time-consuming regrinding. The insert forms part of a simple system consisting of the insert, a matching outer holder or boring bar, a backing clamp or mounting set, and replacement screws; this standardised approach reduces inventory complexity and shortens intervention times. In practice, fewer interventions and the option to index both sides lead to lower per-cutting-edge costs and improved overall equipment effectiveness in series production.

Material recommendations and practical application notes

This insert is optimised for machining steel and similar materials where interrupted cuts or lower speeds are anticipated. The T9235 grade offers wide applicability across unalloyed and alloyed steels when stability is limited; selecting a chipbreaker and grade to suit the workpiece material and cutting conditions remains essential. For finishing cuts on more stable set-ups, a finer corner radius or a different grade may be preferable. Always verify machine power and fixture rigidity before increasing cutting data, and follow established wear-monitoring practices to maintain consistent component quality.

FAQ

What materials is this insert best suited for? This insert is primarily intended for machining steel; the T9235 grade is selected for toughness in interrupted- or unstable-cut conditions.

How many usable cutting edges does the insert offer? The DNMG150408 is double-sided, providing multiple indexable edges per insert to extend service life before replacement.

Is the insert compatible with standard DNMG holders? Compatibility depends on holder form, relief angle, tolerance class, fastening, size and thickness; the DNMG150408 is ISO‑standard and generally fits standard DNMG holders when specifications match.

What does the CVD coating provide? The CVD coating on the cemented carbide enhances wear resistance and edge protection under moderate cutting speeds, while the base grade maintains impact resistance for interrupted cuts.

Can this insert be used for finishing passes? The 0.8 mm corner radius and the tougher T9235 grade are optimised for robustness rather than ultra-fine finishing; for final finishing, consider a smaller corner radius or a grade optimised for surface finish.
