DNMG 150612 T9215 — Indexable turning insert for medium steel by Tungaloy

DNMG150612 T9215 is an ISO-standard indexable turning insert designed for external and internal turning in medium steel applications, offering robust wear resistance and suitability for continuous to slightly interrupted cuts.

• CVD-coated carbide for wear resistance
• Double-sided chipbreaker for versatile cutting
• ISO geometry for broad holder compatibility
• 1.2 mm corner radius for balanced strength

Consistent productivity for medium-steel turning

The CVD-coated carbide grade T9215 is engineered as a first choice for medium steel machining, combining high wear resistance with good fracture toughness to maintain productivity under continuous or slightly interrupted cutting conditions. The insert’s double-sided chipbreaker design helps control chips and reduce downtime by improving chip flow and evacuation. Selecting this insert supports predictable tool life and process stability, which in turn reduces unplanned tool changes and improves overall manufacturing throughput.

Secure clamping and ISO compatibility reduce setup risk

With an ISO-standard form and a 55° lead angle, the rhomboid insert mates with a wide range of compatible external holders and boring bars. The presence of a cylindrical locating hole ensures reliable positioning and repeatable clamping when used with the correct underlay and clamping set. Because compatibility is governed by form, clearance angle, tolerance class, fixation and plate thickness, this insert integrates smoothly into standard turning systems and simplifies inventory management for workshops running multiple holder types.

Technical coating and geometry explained for practical advantages

The CVD coating applied to this carbide substrate enhances hardness at operating temperatures and improves resistance to abrasive wear, while the substrate core provides the necessary toughness against chipping. The 6.35 mm plate thickness and 15 mm inscribed circle offer a balance between rigidity and cutting access, and a 0° clearance angle on the insert relates to how the tool engages the workpiece in common turning set-ups. For engineers and shop planners, these specifications translate into measurable benefits: sustained surface finish quality and reduced frequency of insert breakouts when matched to appropriate cutting parameters.

Handling, storage and application guidance for reliable results

The rhomboid shape and double-sided nature of the insert provide four usable cutting edges per indexable plate, optimising cost per edge in serial production. The 1.2 mm corner radius offers a compromise between stronger cutting-edge support and acceptable surface finish for general turning tasks. For best results in medium steel, pair the insert with a stable external holder, set cutting parameters consistent with continuous cutting, and select the chipbreaker and grade in line with workpiece material and machine rigidity. Routine inspection and controlled tool-change procedures will preserve performance and support predictable production cycles.

FAQ

What materials is this insert intended for?
The DNMG150612 T9215 insert is specified for medium steel machining; the T9215 CVD-coated carbide grade provides wear resistance and toughness suitable for continuous to slightly interrupted cuts in steel.

How many cutting edges are available per insert?
As a double-sided rhomboid insert, each DNMG plate offers four usable cutting edges through indexing, which optimises cost per edge during serial production.

Is the insert compatible with standard ISO holders?
The insert follows ISO geometry; compatibility depends on matching form, clearance angle, tolerance class, fixation, size and thickness with the chosen external holder or boring bar.

What advantages does the T9215 coating deliver?
The T9215 CVD coating increases surface hardness at operating temperature, improving abrasive wear resistance while the carbide core maintains fracture toughness for reliable edge life.

Can this insert cope with interrupted cuts?
The grade and geometry are suitable for continuous and slightly interrupted cuts; heavier interruptions should be evaluated with appropriate grade and chipbreaker selection to avoid premature edge chipping.
