CNMG 120408 T9215 indexable insert for turning — Tungaloy (ISO turning inserts, CVD-coated carbide)

The CNMG120408 T9215 is an ISO rhombic indexable insert designed for external and internal turning in medium steel, offering a balanced mix of wear resistance and fracture toughness for continuous to slightly interrupted cuts.

• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• Rhombic CNMG 120408, 0° clearance
• Double-sided chipbreaker, cylindrical hole

Reliable performance for medium steel turning

The insert is based on a CVD-coated carbide substrate and the T9215 grade, engineered as a first choice for medium steel machining. The coating increases wear resistance while the substrate provides fracture resistance, which together support stable cutting at elevated productivity levels. For operators seeking a dependable cutting edge, the balanced material combination reduces unexpected tool failures and prolongs consistent component quality during extended production runs.

Compatibility and system integration for a seamless toolset

Compatibility is governed by form, clearance angle, tolerance class, attachment style, size and thickness; the insert conforms to ISO dimensions and fits standard CNMG indexable holders when matched correctly. The rhombic shape with an 80° cutting angle and a 0° clearance require appropriate clamping and support from the external holder or boring bar to ensure positional stability. Where holder geometry or tolerance differs, selecting the matching support shim and fastening screw completes the system and prevents chatter or premature wear.

Operational advantages that reduce process costs

The double-sided chipbreaker design enables reuse of both cutting edges, effectively doubling edge life under suitable conditions and supporting predictable tool-change intervals. The 0.8 mm nose radius helps achieve a compromise between edge strength and surface finish, reducing the need for secondary operations on many turned parts. The insert is recommended for continuous to light interrupted cuts; using the correct feed and speed settings maximises tool life and minimises cycle time, delivering measurable efficiency improvements in shop-floor production.

FAQ

What materials is this insert best suited for?
The Tungaloy CNMG120408 T9215 insert is optimised for medium steel applications; the T9215 grade combines wear resistance with toughness for productive turning.

Can the insert be used for internal turning as well as external turning?
Yes, the ISO rhombic geometry and cylindrical hole allow use in appropriate external holders and boring bars for both external and internal turning operations.

How does the double-sided chipbreaker affect tool life?
The double-sided chipbreaker provides two usable cutting edges per index, effectively extending usable life of the insert under matching cutting conditions.

What should be considered when matching a holder to this insert?
Holder compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; verify the holder conforms to ISO specifications for CNMG 120408 before mounting the insert.
