DPMT 070208 T9215 ISO turning insert — rhombic 55° geometry by Tungaloy

The DPMT 070208 T9215 is an ISO‑standard rhombic turning insert designed for external and internal turning of medium‑grade steels

• CVD‑coated cemented carbide T9215 for wear resistance
• Ideal for medium‑steel turning applications
• Rhombic insert with 55° cutting angle
• 0.8 mm corner radius for reliable finishes

Consistent productivity for medium‑steel turning

The CVD‑coated cemented carbide grade T9215 combines high wear resistance with fracture toughness, making it suitable for sustained productivity in continuous to slightly interrupted cuts. The coating reduces flank wear and extends tool life under stable cutting conditions, while the carbide substrate preserves edge strength where tool engagement varies. For machining tasks where consistent component quality and predictable tool change intervals matter, this grade offers an economically efficient balance between life and performance. Compatibility with ISO holder systems ensures predictable clamping and repeatability across tool changes.

Geometry and edge preparation that improve surface quality

A rhombic 55° geometry with a 0.8 mm corner radius and a clearance angle of 11° provides a favourable compromise between cutting edge strength and surface finish. The insert thickness of 2.38 mm contributes to rigidity in the holder, reducing vibration in light‑to‑moderate cuts. The single‑sided chipbreaker geometry controls chip flow for turning of steel grades, promoting stable cutting and easier chip evacuation. In practical terms, the combination of specified edge radius and angle yields finer finishes on shafts and bores while maintaining durable cutting performance during longer production runs.

System compatibility and practical set‑up for workshop use

As an ISO‑standard turning insert, the plate requires a compatible external holder or boring bar, plus a suitable pad/clamp set and replacement screws for secure mounting. Compatibility depends on insert shape, clearance angle, tolerance class, fixing method, size and thickness — these parameters ensure correct seating and consistent cutting geometry. The plate is supplied with a cylindrical hole and a one‑sided countersink (40°–60°) for positive securing; selecting a holder that matches these features ensures safe clamping and repeatable positioning. For typical applications — external turning, internal turning and medium steel workpieces — select the chipbreaker and grade to suit material, process stability and the intended feed/speed range.

FAQ

Is this insert suitable for external turning of medium‑strength steels?
The DPMT 070208 T9215 insert is optimised for medium‑grade steel turning; the T9215 CVD coating and carbide substrate offer wear resistance and edge strength appropriate for external turning operations.

What holders are compatible with the DPMT 070208 geometry?
Compatibility is determined by insert form, size 07, thickness 2.38 mm, clearance angle 11° and the 55° geometry; choose an ISO‑compatible external holder or boring bar that accepts rhombic DPMT inserts with the specified fixing and tolerance class.

How does the 0.8 mm corner radius affect the finish and tool life?
A 0.8 mm corner radius increases edge strength compared with finer radii, improving resistance to edge chipping and supporting better surface finish under steady cutting conditions.

Can the insert be used for interrupted cuts?
The T9215 grade is designed for continuous to slightly interrupted cuts; for heavy interruptions, consider grades and chipbreakers tailored to increased shock loading.

What is the purpose of the countersunk hole design?
The cylindrical hole with a one‑sided countersink (40°–60°) provides secure positive locating and clamping, ensuring repeatable seating and consistent cutting geometry when used with matching clamping sets.
