CNMG120408 T9225 turning insert — Tungaloy, CVD‑coated carbide, 0.8 mm nose radius

The CNMG120408 T9225 is an ISO‑standard turning insert engineered for medium to heavy steel machining, offering a robust universal grade for varying cutting conditions.

• CVD-coated carbide for wear resistance
• Robust universal grade T9225 for steels
• 0.8 mm nose radius for controlled finishes
• Double-sided chipbreaker with cylindrical hole

Boost throughput with consistent cutting performance

The CNMG120408 T9225 combines a CVD‑coated surface with a tough carbide substrate to deliver extended tool life and repeatable edge condition under demanding loads. This results in improved process stability and fewer tool changes, increasing uptime on production turning centres. For shops running mixed batches, the universal grade T9225 reduces the need for frequent grade swaps while maintaining cutting efficiency and stability.

Toughness and edge security for interrupted and variable cuts

The CVD layer provides enhanced wear resistance while the substrate ensures the necessary toughness for slightly interrupted cuts or changing engagement. This balance between abrasion resistance and edge strength translates into predictable tool life and consistent component quality. Explanation: a CVD coating deposits hard ceramic layers on the carbide, reducing flank wear and improving edge endurance without compromising the insert’s capacity to absorb shocks.

Easy integration with ISO holder systems for secure clamping

As an ISO‑standard CNMG insert, compatibility with holders is determined by form, clearance and tolerance class, fastening method, size and thickness. The rhombic shape with cylindrical hole and a plate thickness of 4.76 mm provides straightforward mounting in standard external and internal turning holders. The specified 0° clearance and 80° approach angle support predictable tool geometry and make setup reproducible across machines and operators.

Practical handling that supports surface quality and flexibility

A 0.8 mm nose radius offers a balanced compromise between robustness and finish — adequate for general-purpose turning while still permitting acceptable surface quality on many steel grades. The double-sided chipbreaker increases versatility, allowing use on both faces to extend service between indexings. For finishing-critical work, combine the radius and cutting parameters to achieve the required roughness; for roughing, the tougher grade and geometry resist chipping and keep production steady.

FAQ

Is this insert suitable for medium and heavy steel turning?
The CNMG120408 T9225 insert by Tungaloy (SKU 6781365-Tungaloy) is a robust universal grade formulated for medium to heavy steel machining, offering the toughness required for variable engagement and interrupted cuts.

What benefits does the CVD coating provide?
A CVD‑coated carbide insert combines a hard ceramic coating with a tough substrate to reduce abrasive wear and maintain edge integrity, which improves tool life and dimensional consistency during prolonged turning cycles.

How does the 0.8 mm nose radius affect component finish?
A 0.8 mm nose radius balances strength and surface quality: it supports a stable cutting edge for general turning while permitting acceptable surface finishes; finer radii would enhance finish but lower edge strength.

Can the insert be used in standard ISO holders?
Yes. The CNMG120408 conforms to ISO CNMG geometry; compatibility depends on matching form, clearance, tolerance class, fastening and thickness to the holder specification.

Is the double-sided chipbreaker suitable for interrupted cuts?
The double-sided chipbreaker, combined with the T9225 grade’s toughness, is well suited to applications with light interruptions or variable engagement, offering reliable chip control and extended indexing.
