CCMT120404 T9225 — ISO rhombic turning insert, CVD‑coated carbide, 0.4 mm radius (Tungaloy)

CCMT120404 T9225 is a robust ISO‑standard indexable insert intended for medium‑to‑heavy turning applications, offering a universal grade for variable cutting conditions.

• ISO rhombic CCMT geometry, standardised fit
• CVD‑coated carbide grade T9225 for toughness
• 0.4 mm corner radius for mixed operations
• 7° relief angle and secure hole mounting
• Single‑sided chipbreaker optimised for steel

Proven performance for medium‑to‑heavy steel turning

The CVD‑coated carbide composition and T9225 grade deliver a balance of toughness and wear resistance suited to changing engagement conditions and light interruptions. This specification supports longer tool life and fewer tool changes, resulting in improved machine uptime and reduced process costs. The combination of coating and substrate ensures stable chip formation and reliable edge behaviour when machining steels, making the insert an economical choice for production environments where consistency matters.

Clear compatibility and secure clamping reduce setup time

Provided as an ISO rhombic (CCMT) insert with an included hole and a 7° relief angle, the geometry matches ISO‑standard holders when form, tolerance class, clamping and thickness align. The cylindrical hole with single‑side countersink (40°–60°) guarantees positive location and repeatable clamping, which reduces vibration and improves part finish. Stating these mount criteria explicitly helps workshops verify holder compatibility quickly and avoid costly mismatches during tool assembly.

Practical design that eases process decisions on the shop floor

A 0.4 mm corner radius gives a compromise between strength and edge detail, suitable for finishing and light roughing passes without frequent insert changes. The single‑sided chipbreaker provides controlled chip formation for many steel grades, and the moderate plate thickness (4.76 mm) supports rigidity under higher feed and depth conditions. For external and internal turning, selecting the appropriate chipbreaker and grade like T9225 simplifies tool standardisation and supports predictable results across batches.

FAQ

What materials is this insert best suited for?
The CCMT120404 T9225 insert is formulated for medium‑to‑heavy steel machining; the T9225 grade and CVD‑coating provide toughness and wear resistance suited to variable engagement and lightly interrupted cuts.

How does the mounting hole affect stability?
The cylindrical hole with a single‑side countersink (40°–60°) secures the insert in the pocket and helps ensure repeatable clamping and reduced vibration when the CCMT120404 insert is used with a compatible ISO holder.

Can the insert be used for internal turning as well as external turning?
Yes, the geometry and 0.4 mm corner radius make the CCMT120404 suitable for both external and internal turning operations; the single‑sided chipbreaker aids chip control in many turning scenarios.

Which insert features determine compatibility with a toolholder?
Compatibility is governed by insert form, relief angle (here 7°), tolerance class, clamping method, size and thickness — all of which must match the toolholder specifications for correct fit of the Tungaloy CCMT120404 insert.

What benefit does the T9225 grade offer compared with uncoated grades?
The T9225 CVD‑coated grade offers improved edge stability and better wear behaviour under changing cutting conditions, extending usable tool life versus many uncoated alternatives.
