CNMG 120408 T515 turning insert by Tungaloy (ISO indexable insert)

CNMG120408 T515 is an ISO-form, CVD-coated carbide indexable insert engineered for economical and productive turning, particularly on cast iron.

• CVD-coated carbide grade T515
• Designed for cast iron machining
• Rhombic CNMG form with 80° cutting angle
• Double-sided chipbreaker, cylindrical hole

Productive, economical machining of cast iron with a CVD-coated grade

The T515 grade is a CVD-coated carbide composition optimised for the economical machining of cast iron. This configuration promotes stable chip formation and extended tool life under continuous cutting, which translates into fewer insert changes and lower process costs. For operations with moderate to high material removal rates the coating reduces flank wear, while the substrate offers sufficient toughness for common turning tasks.

Predictable fit and repeatable performance with ISO CNMG geometry

The CNMG form (rhombic, 80° cutting angle) conforms to ISO indexable insert standards, so compatibility with suitable holders is determined by form, relief angle, tolerance class, mounting and thickness. This predictability simplifies tool management: verified holders accepting CNMG120408 inserts allow immediate replacement without further adjustment, ensuring consistent cutting geometry and repetitive performance across batches.

Practical handling, indexing and application guidance for stable results

Featuring a double-sided chipbreaker and a cylindrical mounting hole, the insert is indexable for two usable cutting edges and secures reliably in standard CNMG clamping systems. The 0° relief angle and 0.8 mm corner radius balance edge strength and surface finish, making the insert suitable for both external and internal turning operations. Selection of the chipbreaker and grade should follow workpiece stability and whether cuts are interrupted; the T515 variant is aimed at productive, cost-conscious cast iron machining. For specific cutting data or to adapt the insert to complex setups, consult application tables or the supplier’s technical guidance.

FAQ

What materials is this insert primarily designed for?
This CVD-coated insert is primarily designed for cast iron machining; the T515 grade provides economical performance with good chip control on that material.

Which holder types are compatible with this insert?
Compatibility requires a holder that accepts CNMG120408 geometry; suitability depends on form, relief angle, tolerance class, mounting method and thickness, matching the ISO CNMG standard.

How many cutting edges are available per insert and how is it mounted?
The double-sided design provides two usable edges; the insert is secured via the cylindrical hole in standard CNMG clamping systems and can be indexed when one edge is worn.

What effect does the 0.8 mm corner radius have on machining?
A 0.8 mm corner radius increases edge robustness and helps absorb load peaks, offering a compromise between surface finish and cutting-edge strength for medium-depth cuts.

Can the insert handle interrupted cuts?
Interrupted cutting is possible, but success depends on setup stability; the T515 grade is aimed at economical cast iron operations and should be selected with the appropriate chipbreaker and clamping rigidity.
