DNMG150412 T9225 turning insert — Tungaloy, 55° rhombic, CVD-coated carbide

A DNMG150412 T9225 indexable insert engineered for robust external and internal turning, suited to medium to heavy steel machining where intermittent cuts demand extra toughness.

• ISO rhombic insert DNMG150412, 55° geometry
• CVD-coated carbide grade T9225 for steels
• Double-sided chipbreaker, cylindrical hole
• 1.2 mm corner radius for robust entry

Consistent productivity in medium to heavy turning

The DNMG-style indexable insert delivers predictable material removal rates and reduced setup changes thanks to its ISO form and 55° geometry. The combination of a stable rhombic shape and a 1.2 mm corner radius supports heavier engagement and shock resistance during interrupted cuts, which translates into fewer insert changes and more uptime on the shop floor. For production-oriented turning, the result is higher process stability and a lower cost per component when matched to an appropriate holder and machining parameters.

Extended tool life through coating and substrate design

The CVD-coated carbide substrate specified as grade T9225 is selected for a balance of toughness and wear resistance, making it suitable for varying cut conditions in steel. The CVD layer improves abrasion resistance; as a consequence, flank wear develops more slowly under continuous cutting and short interruptions alike. The insert’s double-sided chipbreaker assists in chip control and consistent surface finish, while the cylindrical hole and reliable clamping ensure repeatable seating and minimal runout during index changes.

System compatibility and practical handling for workshops

Designed as an ISO-standard turning insert, the plate’s fit to a holder depends on shape, relief angle, tolerance class, fastening and thickness; the plate thickness is 4.76 mm and the nominal size is 15. The insert is double-sided for economical indexing and features a cylindrical hole for secure mounting. With a relief angle of 0° and the rhombic form, the insert suits both external and internal turning operations when combined with a compatible toolholder and correct clamp set. Selection of the chipbreaker and grade should follow the workpiece material and machine stability to take full advantage of the insert’s performance.

FAQ

What holder compatibility should be checked for this insert?
Compatibility is determined by insert form and dimensions; the DNMG150412 T9225 turning insert requires a matching ISO DNMG holder that accommodates the 55° rhombic form, 4.76 mm plate thickness and cylindrical hole for correct clamping.

Which materials are recommended for machining with this grade?
The T9225 grade on the DNMG150412 Tungaloy turning insert is formulated for medium to heavy steel machining and performs reliably under slightly interrupted cuts where toughness is required.

Is the insert single- or double-sided and how does that affect indexing?
This DNMG150412 T9225 insert is double-sided, enabling two index positions before disposal; this doubles productive life per plate compared with single-sided designs and simplifies inventory handling.

How does the CVD coating benefit machining performance?
The CVD-coated carbide substrate of the DNMG150412 T9225 insert increases abrasion resistance and extends tool life, particularly when machining abrasive steels or under higher cutting speeds.

What mounting features ensure repeatable seating of the insert?
The cylindrical hole and ISO-compliant dimensions of the DNMG150412 T9225 insert provide secure, repeatable seating when used with the correct holder and clamping set; proper torque and a clean seat are essential for repeatability.
