DNMG110412 T9215 — Tungaloy ISO turning insert for medium-steel turning, rhombic 55°

A DNMG110412 T9215 ISO-standard indexable insert designed for external and internal turning; CVD-coated cemented carbide, rhombic 55° geometry with cylindrical hole and double-sided cutting edges for productive, repeatable metal removal.

• CVD-coated cemented carbide T9215
• Ideal for medium-steel machining
• Rhombic 55° geometry, double-sided
• Cylindrical hole for secure clamping

Optimised wear resistance and steady productivity

The CVD-coated T9215 grade combines high wear resistance with good fracture toughness, making it well suited to the demands of medium-steel turning under continuous to lightly interrupted cuts. The rhombic 55° geometry offers a balance between cutting-edge strength and accessibility for finishing and semi-finish operations. Using a double-sided insert increases the number of usable cutting edges and reduces tool-change frequency, which translates into more productive machining cycles and lower tooling cost per part. Where material compatibility and process stability are prioritised, this grade delivers consistent results.

Compatibility and secure clamping for reliable set-up

Insert-to-holder compatibility depends on geometry, clearance angle, tolerance class, clamping method, size and thickness; the ISO designation ensures interchangeability across standard toolholders. The cylindrical hole and matching screw/clamp arrangement provide positive seating and repeatable positioning in the seat, reducing setup variation. The rhombic profile with a 55° included angle also allows access to a wide range of turning tasks while maintaining edge security. For economical workshop operation, choosing a matching chipbreaker and the correct insert size preserves surface finish and extends edge life.

Practical selection and machining guidance

Select the chipbreaker and grade according to workpiece material, cutting conditions and machine stability: the T9215 grade is the first choice for general medium-steel applications thanks to its stable chip formation and robust edge. In less stable set-ups, reduce feed or choose a sturdier chipbreaker; for fine finishing, a lighter depth of cut and the same grade can still achieve improved surface quality. The ISO system simplifies inventory management—keeping a small range of standard sizes and chipbreakers covers many applications while supporting high uptime and consistent component quality.

FAQ

What materials is this insert recommended for?
The DNMG110412 T9215 Tungaloy turning insert is recommended primarily for medium-steel machining; the T9215 grade balances wear resistance and toughness for productive steel turning.

Is the insert compatible with standard ISO holders?
Yes — the ISO designation DNMG110412 indicates compatibility with ISO-standard holders, provided form, clearance angle, tolerance class, clamping method, size and thickness match the toolholder.

How many usable edges does the insert offer?
This is a double-sided DNMG indexable insert, which provides multiple cutting edges per indexable seat and improves cost-efficiency in repetitive turning tasks.

Can the insert be used for interrupted cuts?
The T9215 grade is suitable for continuous to light interruptions; for heavy interruptions, select a chipbreaker and cutting parameters focused on enhanced edge security.

Which chipbreaker should be chosen for better surface finish?
Choose a chipbreaker matched to the workpiece material and the desired finish; pairing the correct chipbreaker with the T9215 grade helps control chips and improves surface quality while maintaining tool life.
