CPMT080208 T9225 — ISO turning insert for medium‑heavy steel (Tungaloy)

CPMT080208 T9225 is an ISO‑standard rhombic indexable insert designed for turning applications, offering a 0.8 mm corner radius and CVD‑coated carbide for robust cutting performance

• CVD-coated carbide grade T9225
• ISO rhombic insert CPMT 080208
• 0.8 mm corner radius for versatility
• 11° relief angle for stable cutting
• Cylindrical hole with 40°–60° countersink

Greater reliability in demanding turning operations

The CVD‑coated composition of this indexable insert provides a balance between wear resistance and toughness, making it suitable for medium to heavy steel machining where variable cutting conditions occur. The robust universal grade ensures stable cutting edges under intermittent engagement, reducing the risk of unexpected breakage. By choosing a CVD layer paired with a hardened substrate, the tool delivers improved thermal resistance and consistent tool life, which translates into fewer tool changes and more predictable production cycles.

Secure seating and ISO compatibility for simple tool selection

Manufactured to ISO norms, the rhombic plate shape and standardised hole geometry simplify matching to holders. The 11° relief angle and a plate thickness of 2.38 mm enable reliable clamping and correct rake/clearance relationships in common holders; the cylindrical hole with single‑sided countersink (40°–60°) ensures stable torque transmission when fastened. For those less familiar with cutting‑tool terminology: the insert form, clearance angle and tolerance class determine whether an insert fits a particular external holder or boring bar — selecting matching specifications avoids poor seating and chatter.

Shop‑floor benefits that improve process efficiency

With a 0.8 mm corner radius, the insert offers a compromise between edge strength and profile fidelity, suitable for general turning and finishing passes where moderate feed rates and surface quality matter. The one‑sided chipbreaker allows controlled chip formation when paired with the appropriate cutting parameters and workpiece material, reducing rework and swarf issues. These characteristics support a rational production argument: fewer interruptions, predictable cycle times and lower total machining cost per part.

Typical applications and practical set‑up advice

Designed for external and internal turning, this insert performs particularly well in stable set‑ups and semi‑stable conditions where occasional interruptions or variable engagement occur. Select the chipbreaker and grade to match the workpiece and the process stability: for long, steady cuts choose a chipformer suited to continuous chips; for interrupted or unstable cuts, favour the tougher grade and reduced cutting depths. Workpiece materials commonly addressed with this grade include a broad range of steels where a universal, robust solution is preferred.

FAQ

What materials is this insert best suited for?
This insert is designed as a robust universal grade for medium to heavy steel machining; the CVD‑coated carbide composition favours steel applications with varying cutting conditions.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius provides a balance between edge strength and surface finish, making the insert suitable for general turning and moderate finishing passes where both durability and acceptable surface quality are required.

Can this rhombic insert be used in internal turning holders?
Yes. The rhombic plate form and ISO dimensions make it compatible with many internal turning holders provided the holder matches the insert form, clearance angle and tolerance class.

What is the purpose of the cylindrical hole and countersink?
The cylindrical hole with a single‑sided countersink (40°–60°) secures the insert in the clamp, ensuring positive location and torque transmission; this improves seating stability and reduces the chance of insert movement under load.

Which chipbreaker should be selected with this grade?
Selection depends on workpiece material and cut stability; pair this universal grade with a chipformer suited to the desired chip shape — more open chipbreakers for continuous cuts and tougher, more robust profiles for interrupted machining.
