DNMG150408 T9215 indexable turning insert — CVD-coated carbide, 55° lead angle — Tungaloy

DNMG150408 T9215 is an ISO-standard rhombic indexable insert designed for external and internal turning, offering high productivity in continuous to light interrupted cuts.

• ISO rhombic geometry with 55° lead angle
• CVD-coated carbide for medium-steel turning
• Double-sided insert with cylindrical locating hole
• 0.8 mm corner radius for predictable chip control

Productivity through material and grade

The combination of a CVD-coated surface and a carbide substrate gives the insert an excellent balance of wear resistance and fracture toughness. The grade T9215 is specified for medium-steel machining and is engineered to sustain high productivity in continuous to lightly interrupted operations. For production environments this means fewer tool changes and longer periods of stable cutting, translating into improved process efficiency and reduced per-part tooling cost.

Geometry that simplifies holder selection and repeatability

Built to ISO standards, the rhombic form with a 55° lead angle and 0° rake ensures predictable engagement with compatible holders. The insert measures 15 mm across the cutting edge with a plate thickness of 4.76 mm and a 0.8 mm corner radius, features that determine seat fit, clearance and clamping. The presence of a cylindrical hole and double-sided configuration allows two usable cutting edges per index, improving inventory efficiency and guaranteeing repeatable positioning when mounted in ISO-designated clamping systems.

Improved chip control and surface finish

A double-sided chipbreaker tailored to medium steels supports controlled chip formation and evacuation, reducing the risk of surface damage and prolonging effective edge life. The combination of geometry and the T9215 grade contributes to a consistent surface finish and stable cutting forces, which benefits downstream operations and inspection. For workshops aiming for reproducible component quality, this insert supports steady cycle times and reduced rework.

System thinking for economical machining

As an indexable component it is part of a system comprising the insert, matching external holder or boring bar, and the correct clamping set. Changing a worn insert is faster and less costly than remanufacturing a solid tool, and selecting the right chipbreaker and grade for the workpiece yields measurable savings over time. Where process stability is critical, choosing a Tungaloy indexable insert with CVD coating can be a decisive factor in reaching productivity and quality targets.

FAQ

What materials is this insert intended for? The DNMG150408 T9215 insert is optimised for medium-steel machining; the T9215 grade combines wear resistance with fracture security for continuous to light interrupted cuts.

How many usable edges does the insert offer? With a double-sided design and ISO rhombic form, the insert provides two usable cutting edges per side, allowing multiple indexes before replacement.

Which holders are compatible with this insert? Compatibility depends on the ISO form, clearance (frewinkel), tolerance class, fastening method, size and thickness; select a holder that matches the DNMG150408 specifications and clamping arrangement.

What is the significance of the 0.8 mm corner radius? A 0.8 mm corner radius balances edge strength and surface finish; it improves edge robustness while contributing to predictable chip formation in medium-steel turning.

Does the insert require a specific chipbreaker type? The supplied configuration uses a double-sided chipbreaker suitable for medium steels; choosing a different chipbreaker or grade is recommended when machining other materials or under different cutting conditions.

What information is important when ordering spare inserts? Provide the ISO designation DNMG150408, grade T9215, manufacturer Tungaloy and the SKU 6772274-Tungaloy to ensure correct supply and interchangeability.
