DNMG150408 T9215 turning indexable insert by Tungaloy

The DNMG150408 T9215 is an ISO-standard rhombic indexable insert designed for external and internal turning, optimised for medium steel machining.

• CVD-coated carbide grade T9215
• Rhombic 55° insert geometry
• 0.8 mm corner radius for versatility
• Double-sided insert with cylindrical hole
• Negative 0° relief, thickness 4.76 mm

High productivity through a wear-resistant grade

The CVD-coated carbide T9215 combines high wear resistance with notable fracture resistance, making the insert particularly effective for medium steel applications. This composition supports sustained cutting performance during continuous to slightly interrupted operations and helps maintain consistent component quality. By selecting a grade engineered for stability rather than purely for maximum cutting speed, process reliability and tool life are improved, which in turn reduces downtime and tool changes.

Secure clamping and ISO compatibility reduce setup time

The indexable plate follows ISO-standard dimensions, so compatibility with holders is governed by the insert form, clearance angle, tolerance class, fixing method, size and thickness. The rhombic 55° geometry and the cylindrical hole enable a stable clamping interface when used with the correct holder, minimising chatter and improving repeatability. The 4.76 mm plate thickness and double-sided design permit economical index changes while maintaining secure fixation for reliable turning cycles.

Consistent part finish with optimised edge geometry

A 0.8 mm corner radius delivers a balance between edge strength and surface quality, giving a robust cutting edge that resists chipping while producing a fine finish on turned surfaces. The double-sided configuration and the insert’s geometry contribute to even wear progression, which supports repeatable surface roughness over longer runs. For applications demanding dimensional consistency, the combination of controlled edge radius and a stable grade helps preserve tolerance and reduces rework.

Practical selection and system recommendations

When integrating this insert into a tooling system, choose the chipbreaker and insert grade to match the workpiece material, cutting conditions and stiffness of the machine-holding arrangement. A standard system comprises the indexable insert, a matched external holder or boring bar, an underlay shim or clamp set, and the correct replacement screws. For outside and inside turning operations, selecting a double-sided insert with the specified relief and hole style ensures straightforward installation and efficient stock removal, especially when productivity and process security are priorities. The DNMG150408 T9215 designation provides a clear reference when checking compatibility with existing holders.

FAQ

What materials is this insert intended for?
The T9215 grade is tailored for medium steel machining; the DNMG150408 insert performs well on typical steel alloys under continuous to slightly interrupted cuts.

How does the double-sided design affect tool life?
A double-sided insert extends usable life by allowing the workpiece to be machined using a second cutting edge after indexing, which improves economy and reduces tool changes for turning applications.

Which parameters determine holder compatibility?
Compatibility depends on insert form, clearance angle, tolerance class, fixing method, size and thickness—verify these dimensions against the intended holder before use.

Can this insert be used for interrupted cuts?
Yes; the T9215 grade combines wear resistance with fracture toughness, making it suitable for continuous and light to moderate interrupted cuts.

What should be checked when replacing an insert?
Ensure the holder accepts a rhombic 55° insert with 4.76 mm thickness, confirm the cylindrical hole and fixing method match the clamp system, and select the appropriate chipbreaker for the workpiece.
