CNMG120408 T505 indexable turning insert — Tungaloy

CNMG120408 T505 indexable insert for economical external and internal turning of cast iron, ISO-standard rhombic geometry with cylindrical hole for secure mounting

• ISO‑conforming rhombic insert for turning
• CVD‑coated carbide for abrasion resistance
• Double‑sided chipbreaker for reliable chips
• 80° approach angle and 0° clearance angle

Consistent performance for economical cast iron turning

The CVD‑coated carbide grade is tailored for the economical machining of cast iron, providing a balance between cutting speed and tool life. The insert’s substrate and coating combination reduces wear on the cutting edge, which translates into fewer indexings and more uninterrupted production. As a result, cyclic tooling costs are lowered while surface quality remains consistent during routine external and internal turning tasks.

Secure fit and ISO compatibility for straightforward tool selection

Designed to the ISO CNMG120408 form, the rhombic geometry with a cylindrical hole ensures compatibility with a wide range of standard toolholders. The 0° clearance angle and 80° approach angle contribute to predictable seating and force transmission, so fixture and clamping decisions become simpler. This standardised format enables quick replacement and reduces setup time on the shop floor.

Cutting geometry tuned for stable chip control and surface finish

The double‑sided chipbreaker supports controlled chip formation across typical cast iron conditions, including interrupted cuts and varying stability. The 0.8 mm corner radius helps maintain edge strength while delivering acceptable surface quality; larger radii would increase robustness, whereas smaller radii would favour finer finishes. The result is a pragmatic trade-off between durability and finish suited to production turning.

Practical benefits for production efficiency and process security

Using an indexable insert from a reputable supplier brings predictable performance: fewer unexpected stoppages, easier inventory management and straightforward reconditioning choices. The insert’s geometry and coating work together to lower the frequency of tool changes, which reduces non‑productive time and supports a more reliable machining schedule in repetitive turning operations.

FAQ

What materials is this insert suited for? The Tungaloy CNMG120408 T505 insert is formulated primarily for cast iron machining and offers stable cutting and good wear resistance in that material class.

Is the insert compatible with standard CNMG holders? Yes; the insert follows the ISO CNMG120408 form and is compatible with holders specified for CNMG inserts, provided the holder accepts the rhombic shape and cylindrical hole.

How does the T505 grade affect tool life? The T505 CVD coating enhances abrasion resistance on the carbide substrate, which generally leads to longer edge life and fewer indexings in cast iron turning compared with uncoated grades.

Can this insert be used for interrupted cuts? The double‑sided chipbreaker and robust geometry make the insert suitable for interrupted cuts typical in roughing operations on cast iron.

What is the corner radius and how does it influence the cut? The corner radius is 0.8 mm, offering a compromise between edge strength and surface finish; it supports higher stability without sacrificing acceptable finish quality.
