CNMG120408 T9225 indexable turning insert — CVD‑coated carbide, 80° rhombic, Tungaloy

A robust CNMG120408 T9225 indexable turning insert designed for medium to heavy steel turning, offering CVD‑coated carbide performance in an ISO‑standardised geometry.

• CVD‑coated carbide for enhanced wear resistance
• Robust universal grade for medium to heavy steel
• 80° rhombic form with 0° clearance angle
• 0.8 mm corner radius; double‑sided chipbreaker

Consistent cutting performance for demanding turning applications

The CVD‑coated carbide face ensures improved wear resistance under interrupted and variable cutting conditions, while the T9225 grade provides the toughness required for medium to heavy steel machining. This combination reduces flank and crater wear, which supports longer tool life and fewer index changes. The 80° rhombic geometry promotes stable clamping and controlled engagement, making the insert suitable for both light finishing and heavier roughing cuts where tool reliability matters. Technical terms: CVD (chemical vapour deposition) adds a hard coating layer for increased abrasion resistance without sacrificing substrate toughness.

Precise compatibility and mounting for reliable repeatability

Designed to ISO dimensions, the insert fits holders that match form, relief angle and tolerance class; compatibility depends on the holder’s seat, clamping and nominal thickness. The CNMG120408 format with a 4.76 mm thickness and 12 mm inscribed circle provides predictable seating and minimal play when paired with the correct external holder or boring bar. The insert’s cylindrical locating hole and double‑sided chipbreaker support secure fastening and symmetrical use of both cutting edges, helping to reduce downtime caused by incorrect seating and to maintain process stability.

Application advantages and practical benefits on the shop floor

Selecting the T9225 grade means favouring a robust universal insert that copes well with variable engagement and slight interruptions, common in mixed‑batch production. The 0.8 mm corner radius balances edge strength with achievable surface finish, enabling stable roughing passes and acceptable finish quality with fewer tool changes. For workshops aiming to improve throughput, this translates into a reduced number of index cycles and a steadier production flow. For material guidance: this insert is primarily intended for steel machining; match cutting data and holder rigidity to workpiece conditions for optimal results.

FAQ

What materials is this insert suitable for?
The CNMG120408 T9225 insert is intended primarily for steel turning; the T9225 grade provides toughness for medium to heavy cuts under changing engagement.

How many cutting edges are available per insert?
With a double‑sided chipbreaker and the CNMG geometry, the insert offers two usable cutting edges per side, enabling multiple indexes before disposal.

What holder type is required for correct mounting?
An ISO‑compatible external turning holder or boring bar that matches the CNMG form, thickness (4.76 mm) and seating tolerance is required to ensure secure clamping and consistent results.
