DNMG 150408 T9215 turning insert by Tungaloy — CVD-coated carbide, 55°

The DNMG150408 T9215 is an ISO rhombic turning insert engineered for medium-steel machining, offering a balanced combination of wear resistance, breakage safety and reliable chip formation for productive external and internal turning applications

• ISO-standard rhombic insert DNMG shape
• CVD-coated cemented carbide grade T9215
• Double-sided chipbreaker for consistent chips
• 55° approach angle, 0.8 mm nose radius

Engineered for productive turning with measurable benefits

The insert is designed as an ISO-standard turning plate, making it straightforward to select matching holders and bores for stable setups. The 55° approach angle and the rhombic geometry provide an effective compromise between reach and rigidity, which helps to maintain dimensional accuracy during external and internal turning. By choosing the right chipbreaker and grade, the tool delivers a measurable increase in cutting performance and process reliability for series production.

Coating and substrate that extend tool life

The T9215 grade denotes a CVD-coated cemented carbide substrate that unites enhanced wear resistance with sufficient toughness to withstand light interruptions. A CVD coating forms a hard, uniform layer that reduces adhesion and abrasion at the cutting edge; this leads to longer tool life and fewer indexings compared with uncoated grades in similar conditions. For shops aiming to improve throughput, the coating supports extended cutting times and consistent surface finishes.

Practical compatibility and selection guidance

Compatibility with chipper holders depends on the insert’s form, relief angle (0°), tolerance class, clamping method, size and thickness. The plate’s cylindrical hole and double-sided design mean two cutting edges are available per index, improving cost efficiency per edge. Select the chipbreaker and cutting parameters to match the workpiece material and the machining strategy — the T9215 grade is the recommended first choice for medium-hard steels where a balance of wear resistance and breakage safety is required.

Workshop handling and process advantages

The 0.8 mm nose radius and 4.76 mm plate thickness provide a robust edge for dimensional stability while allowing fine control of surface finish. The double-sided chipbreaker helps maintain consistent chip formation, which reduces the need for frequent process adjustments and improves machine uptime. Together, these features support a smooth production flow and predictable tool performance in continuous to lightly interrupted turning cycles.

FAQ

What materials is this insert best suited for?
The DNMG150408 T9215 insert with T9215 CVD-coated cemented carbide is intended as a first choice for medium-grade steels and performs well in continuous to lightly interrupted turning operations.

How does the double-sided chipbreaker influence productivity?
A double-sided chipbreaker provides two usable edges per index and promotes uniform chip formation, which improves edge life consistency and reduces downtime for insert changes.

Which holders are compatible with this ISO insert?
Compatibility is determined by the insert form, relief angle, tolerance class, clamping method, size and thickness; the rhombic ISO geometry of DNMG150408 allows use with standard DNMG holders that match those parameters.

What are the key dimensional features to consider when specifying the insert?
Important values are the 15 mm size, 4.76 mm thickness, 0.8 mm nose radius and the 55° approach angle; these define compatibility and expected cutting behaviour.

How does the T9215 grade affect tool life and surface finish?
The T9215 CVD coating enhances wear resistance while retaining fracture toughness, supporting longer cutting intervals and consistent surface quality in medium-steel turning.
