DNMG150412 T9225 turning insert for Drehen by Tungaloy

The DNMG150412 T9225 is an ISO‑standard rhombic indexable turning insert designed for external and internal turning, offering a tough universal grade for medium to heavy Stahl machining.

• CVD‑coated carbide grade T9225
• Robust universal grade for Stahl machining
• Rhombic 55° geometry, 1.2 mm corner radius
• Double‑sided insert with cylindrical hole

Consistent performance for demanding turning tasks

The insert combines a CVD coating with a carbide substrate to deliver wear resistance under varying cutting conditions. The T9225 grade is specified for medium to heavy Stahl machining, where intermittent cuts or fluctuating engagement demand elevated toughness rather than the finest wear resistance alone. This balance reduces the frequency of tool changes and supports stable cycle times in batch production. The rhombic DNMG form with a 55° included angle provides a versatile cutting edge suitable for general profiling and light finishing steps, while the 1.2 mm radius improves edge strength for roughing passes.

Clear guidance on compatibility and secure clamping

Compatibility between insert and holder depends on geometry, relief angle, tolerance class, fastening style, size and thickness; these factors determine seating and clamp stability. The insert is supplied with a cylindrical hole, enabling positive locating and secure clamping in compatible toolholders. The listed 0° relief angle and the ISO designation simplify selection of matching external holders or boring bars; ensure the holder accepts a rhombic DNMG 15 size with 4.76 mm thickness to achieve correct axis position and repeatable clamping accuracy.

Practical benefits in machining and lifecycle economy

Choosing a universal, robust grade reduces the risk of unexpected edge failure during interrupted cuts and offers a compromise between tool life and process security. The CVD coating enhances thermal resistance at elevated speeds and prolongs edge integrity in sustained contact with Stahl. Fewer tool changes and predictable wear progression translate into higher productivity and less downtime, which supports lean production practices. The insert’s double‑sided design maximises usable edges per index and lowers consumable costs per machined component.

Selecting geometry and process parameters for best results

The DNMG geometry with a 1.2 mm corner radius provides increased chip‑forming volume and a smoother surface finish than sharper radii, making it a reliable choice for semi‑roughing and finishing sequences where consistent surface quality is required. For optimal performance, match feed and depth of cut to the radius: larger radii favour higher radial depths and smoother finishes, while lighter feeds preserve edge life during fine finishing. Use cutting data charts from the holder or insert supplier as a starting point and adjust based on workpiece clamping and machine rigidity.

FAQ

What determines whether this insert fits a particular holder?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; check that the holder accepts a rhombic DNMG 15 insert with 4.76 mm thickness and a cylindrical hole for secure clamping.

Which materials is the insert suited for?
The T9225 grade is a robust universal grade intended for medium to heavy Stahl machining; the CVD‑coated carbide substrate provides thermal resistance and edge stability under typical turning conditions.

Is the insert suitable for interrupted cuts?
Yes. The T9225 composition emphasises toughness to withstand varying engagement and light interruptions while maintaining a reasonable tool life.

How does the DNMG geometry affect surface finish and stability?
The 55° DNMG geometry with a 1.2 mm radius increases edge strength and produces a smoother finish than smaller radii; it is particularly beneficial in semi‑roughing and finishing where machine and workpiece rigidity are adequate.
