DNMG 150408 T9235 DNMG Turning Insert for Turning — Tungaloy

DNMG150408 T9235 is an ISO rhombic turning insert designed for external and internal turning applications, offering a tough CVD-coated carbide grade for interrupted cuts and less stable machining conditions.

• CVD-coated carbide for durable edge life
• 0.8 mm corner radius for controlled feed performance
• Rhombic ISO plate with 55° lead angle
• Double-sided chipbreaker with cylindrical hole

Consistent cutting performance under demanding conditions

The combination of a CVD-coated surface and a carbide substrate provides a balanced mix of wear resistance and toughness. The T9235 grade is formulated for steel machining at lower cutting speeds and where conditions are unstable or cuts are interrupted; this means fewer edge failures and longer periods between tool changes. The plate thickness of 4.76 mm and the 0.8 mm corner radius contribute to a robust cutting edge that tolerates the mechanical shocks associated with interrupted machining. In practice, this translates into steadier cycle times and improved process reliability when machining medium to heavy sections of steel.

Versatile ISO system compatibility for simple tool management

As an ISO-standard insert, the plate is compatible with a wide range of holders provided form, relief angle, tolerance class, fastening, size and thickness match. The system typically comprises an ISO turning insert, a suitable external holder or boring bar, a support/locking set and spare screws, enabling straightforward integration into existing tool inventories. The rhombic geometry and 55° lead angle make the insert suitable for both external profiling and internal turning, while the cylindrical hole simplifies secure clamping. These standardised interfaces reduce tool-change complexity and support leaner stock management in workshops and maintenance departments.

Reliable chip control and seating for interrupted and unstable cuts

The double-sided chipbreaker on this insert assists controlled chip formation and evacuation, lowering the risk of re-cutting and improving surface finish consistency. The nominal 0° relief angle ensures a secure seating geometry suited to rigid clamping — a design choice that helps to minimise vibration when paired with the correct holder rigidity. Together with the CVD-coated carbide composition, these features promote repeatable performance across interrupted cuts and variable material batches, thereby reducing unexpected downtime and enhancing production predictability.

Practical selection and application guidance

Select the chipbreaker style and grade according to workpiece stability, feed rate and depth of cut: for unstable setups or interrupted engagement the T9235 grade and the 0.8 mm radius favour edge strength over maximum speed. When switching from a finer-radius insert, expect improved edge robustness but consider slightly adjusted feeds to maintain desired surface finish. For inventory planning, the ISO designation and double-sided nature of the plate optimise cost per edge and simplify rotation and indexing strategies.

FAQ

Which materials is this insert best suited for?
The DNMG150408 T9235 insert is primarily intended for machining steel, with the T9235 grade optimised for lower cutting speeds, interrupted cuts and less stable conditions.

What is the corner radius and how does it affect machining?
This insert has a 0.8 mm corner radius, which provides a stronger edge for higher feed scenarios and interrupted cutting while maintaining acceptable surface finish for common turning tasks.

Is the plate indexable and how many usable edges are available?
The rhombic DNMG150408 is double-sided, allowing both faces to be used; indexing extends usable life and reduces tooling costs per edge.

How can compatibility with existing holders be checked?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; verify those parameters against the holder specifications to ensure secure clamping for DNMG150408.

Is this insert recommended for interrupted cuts?
Yes — the T9235 grade and the plate geometry are designed to tolerate interrupted cuts and unstable machining conditions, improving production reliability.
