CNMG 120412 T9215 indexable turning insert by Tungaloy — ISO CNMG rhombic, 80°

A CNMG120412 T9215 indexable insert for external and internal turning, engineered for medium-steel machining with a CVD-coated carbide substrate and a rhombic, 80° cutting edge.

• CVD-coated carbide grade T9215
• ISO CNMG 120412 rhombic geometry
• 80° cutting edge with 1.2 mm radius
• Double-sided design with cylindrical hole

Productive medium-steel turning through balanced grade and coating

The combination of a CVD-coated surface and a durable carbide substrate in grade T9215 provides increased wear resistance while maintaining fracture toughness. This balance means higher sustained cutting speeds and longer edge life in continuous to lightly interrupted cuts, translating to fewer tool changes and improved cycle times. The coating reduces adhesion and flank wear, which supports consistent part quality and reduces rework in serial production.

Simple tool management and secure clamping for stable machining

With the ISO CNMG geometry and a standard rhombic form, the insert fits a wide range of CNMG holders; compatibility depends on shape, relief angle, tolerance class, fastening and thickness, allowing flexible integration into existing tool systems. The double-sided design halves the effective cost per cutting edge, while the cylindrical hole and tolerance-compliant dimensions ensure stable clamping and repeatable positioning, improving process reliability and reducing setup time.

Edge integrity and dimensional details for dependable results

An 80° cutting edge combined with a 1.2 mm corner radius gives a compromise between strength and detail: the radius increases edge robustness for roughing passes, yet still allows acceptable surface finish in finishing operations. The insert thickness and size provide sufficient body support to resist bending under load, and the 0° relief angle suits many common turning setups. These characteristics make the insert suited to both external and internal turning tasks where productivity and consistent results are priorities.

FAQ

Which materials is this insert best suited for?
The CNMG120412 T9215 insert is primarily designed for medium-steel machining; the T9215 grade combines wear resistance and toughness for productive performance.

Is the insert reversible and how many cutting edges are usable?
Yes, the indexable insert is double-sided, offering two usable cutting edges per side depending on the holder and indexing practice.

Will this insert fit existing CNMG holders?
Compatibility with standard CNMG holders is expected provided the holder matches the ISO CNMG 120412 form, relief angle and thickness; secure clamping is achieved via the cylindrical hole and correct tolerance class.

Can the insert handle interrupted cuts?
The T9215 grade is suitable for continuous to lightly interrupted cuts, offering a balance between toughness and wear resistance for such conditions.

How does the CVD coating affect machining performance?
The CVD-coated surface on the T9215 carbide reduces flank wear and improves heat resistance, enabling longer tool life and more stable cutting conditions.
