DNMG150416 T9215 — ISO indexable turning insert, CVD-coated carbide by Tungaloy

The DNMG150416 T9215 is an ISO‑standard rhombic indexable insert for external and internal turning, designed for productive machining of medium steels

• CVD-coated carbide grade T9215
• Rhombic DNMG 55° geometry
• 1.6 mm corner radius for robust cuts
• Double-sided chipbreaker with cylindrical hole

Productivity through a wear-resistant grade

The CVD‑coated T9215 grade combines high wear resistance with good fracture resistance, making it a reliable choice for sustained production cycles. By selecting a coated carbide substrate, the insert keeps cutting edges longer under continuous or slightly interrupted cuts, which reduces tool changes and increases machine uptime. The technical design favours consistent performance in medium‑range steel machining, allowing process planners to rely on stable cutting data and predictable tool life.

Secure seating and repeatable geometry for consistent results

Compatibility with the toolholder depends on a precise match of form, clearance angle, tolerance class, clamping method, size and thickness. The ISO‑standard rhombic shape with a 55° insert angle and a thickness of 4.76 mm ensures a snug fit in compatible DNMG carriers and boring bars. The insert’s cylindrical hole provides secure clamping and repeatable positioning, which supports cycle‑to‑cycle accuracy and easier indexation when turning demands quick edge changes.

Improved chip control and edge reliability

The double-sided chipbreaker geometry is engineered to manage chip formation for typical turning feeds and depths in medium steel. Paired with a 1.6 mm corner radius, the edge offers a balance between strength and surface finish: larger radii reinforce the cutting edge under heavier engagement, while the breaker promotes safe chip evacuation. For applications with intermittent cuts, the grade’s fracture resistance contributes to fewer unexpected edge failures and steadier production quality.

System integration and practical application advice

This insert is part of an ISO turning insert system that includes a compatible external holder or boring bar, a shim/clamp set and replacement screws. Typical use cases are external facing and OD/ID turning where repeatable geometry and predictable wear behaviour matter. Selection of the appropriate chipbreaker and grade should match the workpiece material, machining strategy and machine stability to achieve the best throughput and surface quality. The combination of geometry, coating and material makes the insert suitable for shopfloor environments aiming for efficient, repeatable operations.

FAQ

Which materials is this insert best suited for?
The Tungaloy DNMG150416 T9215 is optimised for medium steels; the T9215 CVD coating provides wear resistance and fracture toughness suitable for continuous to lightly interrupted turning applications.

How is compatibility with a toolholder assessed?
Compatibility depends on insert form, clearance angle, tolerance class, clamping method, size and thickness; matching these parameters ensures correct seating and secure clamping for repeatable performance.

Can the insert be used for internal turning (boring)?
Yes, the insert’s ISO geometry and cylindrical hole allow use in appropriate boring bars or internal holders designed for DNMG‑type inserts.

What does the T9215 grade indicate?
T9215 is a CVD‑coated carbide grade offering a balance of high wear resistance and fracture resistance, intended as a primary choice for productive medium‑steel machining.

What is the function of the 1.6 mm corner radius?
A 1.6 mm corner radius increases edge strength and supports better surface finish under heavier engagements, improving robustness during standard turning operations.
