DNMG150608 T9215 – ISO rhombic turning insert for external and internal turning by Tungaloy (CVD-coated carbide, 55°)

The DNMG150608 T9215 is an ISO-standard rhombic turning insert designed for efficient external and internal turning, offering a CVD-coated cemented carbide grade engineered for wear resistance and fracture reliability in medium steel machining

• CVD-coated carbide grade T9215
• Rhombic shape, 55° cutting angle
• 0.8 mm corner radius
• Cylindrical-hole fixing, double-sided chipbreaker

Optimised productivity for medium steel turning

The CVD-coated T9215 grade provides a balanced combination of wear resistance and fracture toughness, making it particularly suitable for medium steel applications where sustained tool life matters. The chemical vapour deposition layer increases oxidation resistance and reduces flank wear under typical cutting temperatures, which translates into fewer insert changes and steadier cycle times. For continuous to slightly interrupted cuts the geometry and coating work together to maintain cutting edge integrity, supporting stable, high-productivity turning operations.

Secure clamping and ISO conformity to reduce set-up risk

Designed as an ISO-standard insert, compatibility with holders is determined by form, free angle, tolerance class, fixation, size and thickness. The rhombic plate with a 55° cutting angle and cylindrical-hole fixing delivers a reliable seating and repeatable clamping force, reducing vibration and rework. The 15 mm inscribed circle and 6.35 mm plate thickness ensure mechanical stability in standard external and internal holders, while the double-sided chipbreaker enables reversal for economical use of the cutting edges.

Consistent surface finish and controlled cutting forces

A 0.8 mm corner radius delivers a compromise between tool strength and surface quality: larger radii improve edge life and damp cutting forces, smaller radii allow finer detail and lower cutting forces. The rhombic geometry and chipbreaker design combine to evacuate chips effectively, which supports a consistent surface finish on turned parts and helps maintain predictable tool life. Where improved dimensional accuracy is required, selecting the correct feed and radius reduces the need for subsequent finishing passes.

Practical selection advice for process planners

Choose the appropriate chipbreaker and insert grade to match workpiece material, cutting conditions and machine stability. For medium steels the T9215 grade is a first choice for productive cutting with good edge life; for heavier interruptions or harder materials consider alternative grades. The system comprises the ISO insert, a matching external holder or boring bar, a seat and clamping set plus replacement screws. If compatibility with a specific holder is uncertain, verify form, free angle and thickness against the holder specification before fitting.

FAQ

What materials is this insert best suited for?
The T9215 grade is engineered for medium steel machining; the DNMG150608 T9215 insert combines wear resistance and toughness for productive cutting of these materials.

Is the insert reversible to use both edges?
Yes, the insert has a double-sided chipbreaker and is reversible, allowing economical use of both cutting edges before replacement.

How is compatibility with a toolholder ensured?
Compatibility depends on the insert form, free angle, tolerance class, fixation, size and thickness; verify these parameters against the holder specification when selecting the matching clamping set.

What benefits does the T9215 CVD coating provide?
The CVD-coated T9215 grade delivers enhanced oxidation resistance and reduced flank wear, improving edge life and process stability during turning.

When should the 0.8 mm corner radius be used?
The 0.8 mm corner radius is a versatile choice for balancing tool life and surface finish in general turning tasks, especially when moderate edge strength and good finish are required.
