TNMG110308 T9215 TNMG turning insert — CVD-coated carbide, 0.8 mm corner radius (Tungaloy)

The TNMG110308 T9215 is an ISO-standard triangular turning insert for external and internal turning, engineered for medium steel machining and designed for continuous to slightly interrupted cuts.

• CVD-coated carbide grade T9215
• 0.8 mm corner radius for balanced strength
• ISO TNMG form, 11 mm inscribed circle
• Double-sided chipbreaker with cylindrical hole

High wear resistance for steady production

The CVD-coated carbide grade T9215 offers a deliberate balance between wear resistance and edge toughness, making it particularly effective in medium steel machining. The coating delivers thermal and abrasive protection that reduces flank wear under continuous operation, extending in-service life and stabilising machining cycles. For production environments seeking predictable tool life and fewer insert changes, this grade supports higher throughput without sacrificing component quality.

Geometry tailored for repeatable surface quality

With a 60° triangular form and a 0.8 mm corner radius, the insert achieves a compromise between robustness and achievable surface finish. The 0.8 mm corner radius provides core strength at the cutting edge while still permitting acceptable finishes on turned parts; smaller radii would improve finish but reduce edge strength, larger radii would demand more power. The zero-degree relief angle and 3.18 mm thickness contribute to a stable seating in the pocket, while the cylindrical hole and double-sided design allow reversal for economical use of both cutting edges.

Practical advantages on the shop floor

A double-sided chipbreaker reduces tooling costs by offering two usable edges per insert and supports efficient stockkeeping. The integrated chip control aids continuous swarf evacuation and promotes consistent surface results, especially when combined with a suitably rigid holder and correct cutting data. The combination of CVD-coated surface and optimised chip control makes this insert a sound choice where productivity and component consistency are primary concerns.

System compatibility and selection guidance

As an ISO-standard turning insert, compatibility with a holder depends on form, relief angle, tolerance class, fastening method, inscribed circle and thickness; ensure the chosen toolholder matches the TNMG geometry and the mounting screws and clamping plate specified by the holder manufacturer. Select the chipbreaker and grade according to workpiece stability and machining type: the listed grade is ideal for medium steel in continuous to light interrupted cuts. For less stable setups or heavily interrupted cuts, consider a more robust geometry or adapt cutting parameters to maintain edge life.

FAQ

Which materials is this insert intended for?
The Tungaloy TNMG110308 T9215 insert is designed primarily for medium steel machining; the CVD-coated carbide grade T9215 combines wear resistance and toughness suited to continuous and slightly interrupted cuts in steel.

How does the chipbreaker affect performance?
The double-sided chipbreaker on this TNMG geometry promotes stable chip formation and evacuation, improving surface finish consistency and reducing the risk of chip re-cutting during medium steel turning operations.

Is the insert reversible and how does that improve cost-efficiency?
Yes, the insert is double-sided and reversible; the TNMG110308 design provides two usable cutting edges, effectively halving the cost per edge compared with single-sided inserts under comparable conditions.

What should be checked for holder compatibility?
Compatibility depends on the TNMG form, relief angle (0°), tolerance class, fastening type, inscribed circle (11 mm) and thickness (3.18 mm); confirm that the selected holder matches these parameters for correct seating and clamping.

Can this grade handle lightly interrupted cuts?
The T9215 grade is suitable for continuous to lightly interrupted cuts in medium steel, offering a good compromise between edge strength and wear resistance for productive operations.
