DNMG 150404 T9235 indexable insert for turning — Tungaloy, CVD-coated carbide, 55° rhombic

DNMG150404 T9235 Tungaloy indexable insert for ISO-compliant external and internal turning, designed for interrupted cuts and unstable machining conditions

• CVD-coated carbide grade T9235
• Rhombic DNMG with 55° cutting angle
• 0.4 mm corner radius for robustness
• Double-sided chipbreaker, cylindrical hole

Improved performance when machining unstable or interrupted cuts

The combination of a CVD-coated surface and a tough carbide substrate in this grade was chosen to withstand low cutting-speed strategies and heavy interruption. The coating reduces adhesion and protects the cutting edge from thermal and abrasive wear while the substrate absorbs impacts, which results in more consistent edge life under variable conditions. As an indexable insert, the component enables fast tip changes, reducing non-productive time and maintaining machining stability when interruptions or vibration occur.

Predictable fit and secure clamping for stable results

Produced to the ISO DNMG form, the insert matches standard holders when the seat geometry, relief angle and tolerances correspond; the cylindrical hole aids positive location and repeatable clamping. The specified relief angle of 0° and the rhombic 55° geometry contribute to predictable cutting forces, helping to reduce chatter in less rigid set-ups. Clear compatibility between insert and holder simplifies process planning and avoids unexpected fit issues during tool changes.

Lower cost per part through longer edge life and robust edge geometry

The T9235 grade is formulated for toughness rather than maximum speed, making it suitable for steels and unstable cutting. The 0.4 mm corner radius increases edge strength and resistance to chipping, which reduces frequent indexings and part rework. Together, coating and substrate selection improve wear behaviour and help to lower the effective tooling cost by extending service intervals and maintaining surface quality across interrupted turning cycles.

Practical guidance for integration into production

For reliable results, match the insert’s double-sided chipbreaker and grade to the workpiece material and the cycle type (roughing vs finishing). Use a holder rated for DNMG 55° geometry and ensure secure clamping with correct torque on a compatible screw and clamp system. Typical applications include external and internal turning of steels where process instability or interrupted cuts are expected; selecting the right feed and cutting speed for a tougher grade will deliver steadier performance and fewer unscheduled stops.

FAQ

What materials is this insert designed for?
The DNMG150404 T9235 insert is engineered primarily for steel machining; the T9235 carbide grade emphasises toughness for interrupted cuts and unstable turning operations.

How does the chipbreaker affect cutting?
The double-sided chipbreaker on this indexable insert improves chip control for varying depths of cut and helps maintain consistent surface quality during external and internal turning.

Is this insert compatible with standard DNMG holders?
Yes — the DNMG150404 conforms to ISO DNMG geometry; compatibility depends on holder form, relief, tolerance class and clamping style, and the insert’s cylindrical hole aids repeatable seating.

What advantages does the CVD coating provide?
The CVD-coated layer enhances flank and crater wear resistance and reduces adhesion at the cutting edge, which is particularly beneficial at lower cutting speeds and in unstable machining conditions.
