DNMG 150404 T9215 turning insert for turning — Tungaloy

A DNMG150404 T9215 ISO‑standard turning insert engineered for external and internal turning in medium‑range steel machining.

• CVD‑coated carbide for high wear resistance
• Suited to medium steel machining
• Rhombic geometry with 0.4 mm corner radius
• Cylindrical hole and 4.76 mm plate thickness

Longer tool life through optimised grade and coating

The supplied grade combines CVD‑coated surface technology with a robust carbide substrate, delivering high wear resistance while preserving fracture toughness during continuous or lightly interrupted cuts. This formulation is intended as a first choice for medium‑range steel applications, where consistent metal removal rates and predictable tool life reduce unplanned downtime. The chemistry and coating are designed to balance abrasive wear resistance with the ability to resist chipping at the cutting edge, which supports more stable cycle times and fewer tool changes.

Secure clamping and ISO‑compatibility for flexible set‑ups

Built to ISO dimensions, the insert’s form and tolerance class allow reliable fitment in standard holders; compatibility is determined by shape, relief angle, fastening style, size and thickness. The rhombic geometry and the cylindrical hole enable secure seating and repeatable positioning when paired with a suitable outer holder or boring bar. A 0° relief angle and a plate thickness of 4.76 mm provide robust support under radial loads, so clamping stability is improved and insert life is extended in routine turning operations.

Predictable surface quality with controlled edge geometry

A 0.4 mm corner radius gives a balance between edge strength and finish: it supports vibration damping and increases edge durability while still permitting acceptable surface quality on shafts and bores. The double‑sided chipbreaker design allows reversible use of the cutting edges, doubling available edges per insert and contributing to economical machining. When selecting a chipbreaker and grade, match the breaker profile to the material and the intended feed and depth of cut to ensure consistent swarf control and surface finish.

System approach for efficient tool management

The insert is intended to be used as part of a system: an ISO‑standard indexable insert, the respective external holder or boring bar, a suitable shim or clamping set, and replacement screws form the full assembly. Standardised geometry eases inventory management and simplifies spindle‑side tooling changes. Where higher demands arise, density of the carbide substrate and coating properties make this insert suitable for ramped feeds or frequent starts and stops within its rated application range.

FAQ

Which materials is this insert suitable for?
The DNMG150404 T9215 insert is optimised for medium steel machining; the CVD coating and carbide substrate provide wear resistance and edge security for continuous to lightly interrupted cuts.

Is the insert reversible and how many cutting edges are available?
Thanks to the double‑sided chipbreaker, the insert offers two effective cutting edges per side, allowing multiple indexings before disposal.

What clamping features must the holder provide?
A holder must match the rhombic form, plate size and thickness; the cylindrical hole requires a compatible fastening arrangement to ensure repeatable seating and axial support.

How does the corner radius affect finish and tool life?
The 0.4 mm corner radius improves edge strength and reduces chipping risk while delivering a practical surface quality for shafts and bores in steel components.

Can this insert be used for interrupted cuts?
The T9215 grade is suitable for continuous and slightly interrupted cuts; for heavy interruptions, consider a grade and chipbreaker combination tailored to the specific load case.
