DNMG 150408 T9225 indexable turning insert — 55° rhombic, 0.8 mm radius (Tungaloy)

DNMG 150408 T9225 is an ISO-standard indexable insert designed for external and internal turning, offering a tough universal grade for medium to heavy steel machining.

• CVD-coated carbide for high wear resistance
• Rhombic 55° geometry for versatile turning
• 0.8 mm corner radius for durable edges
• Double-sided chipbreaker with centre hole

Reliable performance for medium to heavy steel turning

The CVD-coated carbide composition delivers increased wear resistance and consistent edge life in interrupted and variable cutting conditions. The insert’s universal grade T9225 is tailored for turning operations where toughness matters — it absorbs shocks from undercut or slightly interrupted cuts while still maintaining dimensional accuracy. For production environments that require dependable repeatability, this indexable insert reduces tool change frequency and supports predictable process planning.

Geometry and edge design that support versatile machining

With a 55° rhombic geometry and a 0.8 mm corner radius, the insert balances versatility and strength: the acute rhombic shape allows entry to diverse profiles while the modest radius maintains a robust cutting edge for heavier engagement. The double-sided chipbreaker aids chip control across a range of feeds, and the centre (cylindrical) hole enables secure clamping in standard ISO-compatible holders. These features together support efficient material removal and stable surface finish in typical turning cycles.

System compatibility and practical integration

The insert conforms to ISO dimensions, so compatibility with a matching external holder, clamping set and replacement screws is determined by form, clearance angle, tolerance class, fixation type, size and thickness. The specified 0° clearance angle and 4.76 mm plate thickness suit many common external turning holders; confirmation of holder fit prevents assembly issues and optimises clamping stability. When selecting an insert for a tooling system, choose the chipbreaker and grade that match material, operation and machine rigidity for best results.

FAQ

What materials is this insert intended for?
The Tungaloy DNMG150408 T9225 insert is a universal grade primarily intended for medium to heavy steel machining and performs well under varying engagement conditions.

How does the T9225 grade behave with interrupted cuts?
The T9225 CVD-coated carbide grade is formulated to offer increased toughness, making the insert tolerant of slightly interrupted cuts and changes in cutting conditions without rapid edge failure.

Which holders fit this ISO insert?
Compatibility depends on the holder’s form, clearance, tolerance class, fixation and thickness; the DNMG150408 follows ISO-standard dimensions, so it fits holders designed for DNMG 150408 inserts when those parameters match.

Is chip control effective across feeds?
Yes; the double-sided chipbreaker provides reliable chip control across a practical range of feed rates, supporting steady surface quality and safe chip evacuation.

Can this insert be used for internal turning?
The geometry and hole position allow use in appropriate internal turning holders; ensure the selected holder accepts the DNMG150408 form and size before mounting.
