DNMG150412 T9215 CVD‑coated carbide turning insert (55°) — Tungaloy

The DNMG150412 T9215 is an ISO rhombic indexable insert engineered for medium‑steel external and internal turning applications, offering robust performance in continuous to lightly interrupted cuts

• CVD‑coated T9215 for medium steel
• Rhombic DNMG shape, 55° cutting angle
• Double‑sided insert with 1.2 mm radius
• Compatible with ISO turning toolholders

Consistent productivity for medium‑steel turning

The rhombic DNMG geometry with a 55° cutting angle delivers a reliable cutting edge for both external and internal turning tasks. The CVD‑coated carbide grade T9215 is formulated to balance wear resistance and fracture toughness, which helps maintain tool life under steady cutting conditions. For production environments where cycle time and part quality matter, this insert reduces downtime through predictable performance and repeatable edge life.

How the coating and substrate benefit machining efficiency

A CVD‑coating on a carbide substrate protects the cutting edge at elevated temperatures and reduces abrasive wear, extending usable life compared with uncoated grades. The T9215 grade is optimised for medium‑strength steel, enabling higher productivity without compromising surface finish. The double‑sided design and indexed edges mean two usable cutting corners per side, improving cost efficiency per edge and simplifying inventory management for frequent turning operations.

Practical compatibility and handling in the workshop

Compatibility with a holder depends on form, clearance angle 0°, tolerance class, fixation method, size and thickness. The insert has an inscribed size of 15, a thickness of 4.76 mm and a corner radius of 1.2 mm, and is supplied with a cylindrical hole for secure clamping. A typical system comprises an ISO‑compatible turning holder, a support shim or clamping kit, and replacement screws. Selecting the correct chipbreaker and grade ensures optimal chip control for continuous to lightly interrupted cuts and reduces the risk of edge chipping.

Choosing the right cutting geometry and grade

The DNMG150412 form suits a wide range of turning operations; choose a chipbreaker matching the material and feed conditions. For medium‑steel workpieces, the T9215 grade is the first choice where a compromise between long tool life and resistance to mechanical shock is required. When facing more aggressive interruptions or harder materials, consider alternative grades or geometries; for standard production of shafts, journals and turned components, this insert provides a dependable balance of life and performance.

FAQ

What materials is this insert designed for?
The DNMG150412 T9215 insert is designed primarily for medium‑strength steel; the T9215 CVD‑coated carbide combines wear resistance and toughness for such applications.

Can the insert be used for internal and external turning?
Yes — the rhombic DNMG shape and 55° cutting angle make the insert suitable for both external and internal turning operations.

How does the hole style affect clamping?
The cylindrical hole provides precise centring and stable clamping in ISO‑compatible holders; DNMG150412’s hole style ensures repeatable fixation in the toolholder.

Is the chip control suitable for interrupted cuts?
The double‑sided chipbreaker is intended to perform well in continuous to light interrupted cuts; for heavy interruptions, a specialised geometry may be preferred over the standard chipbreaker.

Which dimensions should be checked for holder compatibility?
Check the insert’s size (15), thickness (4.76 mm), corner radius (1.2 mm), clearance angle (0°) and hole form; these determine mechanical fit and correct seating in the holder.
