DNMG 150412 T9215 – DNMG turning insert for turning, Tungaloy

The DNMG150412 T9215 is an ISO-standard rhombic turning insert optimised for medium-steel turning, offering high wear resistance and good fracture toughness for continuous to light interrupted cuts.

• CVD-coated carbide T9215 grade
• ISO DNMG rhombic geometry
• Corner radius 1.2 mm for strength
• Double-sided chipbreaker design
• Cylindrical locating hole for clamping

Boosted productivity through wear-resistant coating and grade

The combination of CVD-coated carbide and the T9215 grade delivers a reliable balance between wear resistance and edge toughness, making it a consistent choice for higher-volume turning operations. This coating technology protects the substrate against abrasive wear while maintaining the cutting-edge integrity required for sustained production. As a result, cycle times remain stable and tool-change intervals extend, supporting improved overall equipment effectiveness and predictable throughput.

Clear guidance on holder compatibility and mounting

Compatibility is determined by insert form, relief angle, tolerance class, clamping method, size and thickness. The rhombic ISO DNMG form with a specified relief angle of 0°, an insert thickness of 4.76 mm and a cylindrical locating hole requires a matching external holder or boring bar with corresponding geometry and clamping provisions. Correct pairing reduces vibration and ensures repeatable seating, which in turn sustains surface finish and tool life. When selecting a holder, prefer one that matches the tolerance class and clamping style to exploit the insert's properties.

Practical advantages in machining and recommended application

The 1.2 mm corner radius increases edge strength and helps to stabilise the cutting process on medium steels, favouring both external and internal turning tasks. The double-sided chipbreaker contributes to controlled chip formation and stable evacuation under varying depths of cut, improving surface quality while lowering the risk of built-up edge. System assembly typically comprises the ISO insert, a matching holder or boring bar, a backing shim or clamp set and the appropriate fastening screws; attention to clamping torque and seat cleanliness ensures optimal performance. This insert performs best in continuous to light interrupted cuts and is particularly suited where a balance between productivity and predictable wear is required.

FAQ

What materials is this insert designed for?
The DNMG150412 T9215 insert is optimised for medium steel turning; the T9215 grade provides abrasion resistance and toughness for a wide range of steel alloys.

Is the insert indexable and reversible?
Yes, the insert is double-sided with a rhombic geometry, allowing indexation to present a fresh cutting edge when required.

What does the T9215 designation indicate?
T9215 denotes a CVD-coated carbide grade tailored for medium-steel applications, combining high wear resistance with good fracture toughness for productive machining.

Which holder characteristics must match the insert?
Holders must match the ISO DNMG form, the relief angle (0°), tolerance class, clamping method, size and thickness; the cylindrical locating hole requires a compatible clamping arrangement.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm corner radius increases edge strength, improving stability and enhancing surface finish under moderate cutting conditions.

Can this insert be used for interrupted cuts?
The grade is suitable for continuous to light interrupted cuts; for heavy interruptions, select a grade or geometry specifically validated for more severe shock loads.
