CPMT 09T304 T9225 indexable turning insert for turning — Tungaloy

The CPMT 09T304 T9225 is an ISO‑standard rhombic indexable insert designed for external and internal turning in medium to heavy steel machining.

• Robust CVD‑coated carbide grade T9225
• Rhombic ISO insert, 80° included angle
• Suitable for medium to heavy steel turning

Consistent cutting under mixed engagement

The CPMT 09T304 combines a CVD‑coated carbide substrate with the T9225 grade to deliver toughness where engagement varies or cuts are slightly interrupted. The coating improves wear resistance while the substrate maintains fracture toughness; this balance leads to more consistent chip formation and extended in‑process life compared with uncoated grades. For production setups that face changing depths of cut, the result is fewer insert changes and steadier machining times, supporting predictable throughput and reduced downtime.

Accurate fit and predictable edge strength

Designed to the ISO geometry, the insert’s 80° included angle and 11° clearance provide a predictable contact geometry that aids tool‑holder alignment and surface finish. The 0.4 mm corner radius offers a compromise between edge strength and finish quality: a larger radius increases toughness and stability during heavy cuts, while still allowing acceptable surface results. Compatibility depends on holder form, clearance, tolerance class, attachment method, size and thickness, so selecting the correct clamping system ensures repeatable positioning and reduced set‑up variation.

Secure clamping and practical system integration

The insert is supplied with a cylindrical hole and a one‑sided countersink (40°–60°), paired with a plate thickness of 3.97 mm; this configuration enables solid contact and reliable screw clamping in standard ISO holders. The rhombic form and single‑sided chipbreaker support conventional negative‑style clamping systems commonly used in turning centres, allowing straightforward integration into existing tool assemblies. These mechanical features translate into enhanced process stability during heavier feeds and depths of cut.

Application guidance for efficient production

Primarily intended for turning operations in medium to heavy steel, the insert performs well when a tougher grade is required for interrupted cuts or variable engagement. Select a chipbreaker and cutting parameters to match material and rigidity—conservative cutting speeds at first will confirm stability before stepping up productivity. For optimal results in batch production, pair the insert with holders rated for the same ISO form and maintain a regular inspection routine for wear‑based changes to avoid unexpected tool failure.
