CCMT 09T308 T9225 — Turning insert (ISO CCMT09T308) by Tungaloy

The CCMT09T308 T9225 is an ISO-standard rhombic turning insert designed for external and internal turning in medium to heavy steel applications.

• CVD-coated carbide grade T9225 for steel turning
• 0.8 mm corner radius for stable chip control
• Rhombic ISO CCMT09T308 form, 7° clearance
• Cylindrical hole with single-side countersink 40°–60°

High-performance coating and grade for longer tool life

The combination of a CVD-coated carbide substrate and the T9225 grade provides a dependable balance between wear resistance and toughness. In practical terms, the coating reduces abrasive wear while the carbide core maintains edge stability under moderate interruption, which means fewer insert changes and more productive machining cycles. The indexable insert is engineered for steel machining, so choosing this grade reduces the risk of premature flank wear and helps sustain consistent dimensional accuracy across batches.

Geometry that enhances stability and surface quality

The rhombic form with an included angle of 80° and a 0.8 mm corner radius delivers a compromise between cutting-edge strength and finish quality. A larger corner radius increases the effective cutting edge engagement, improving surface finish and tool life when turning heavier sections, while the 7° clearance helps avoid rubbing on the flank. The single-side chipbreaker controls chip formation for common turning operations, and the cylindrical hole with single-side countersink (40°–60°) secures the insert reliably in the clamping system, reducing vibration and improving repeatability.

Practical system compatibility and application guidance

Compatibility with holders is determined by form, clearance, tolerance class, mounting, size and thickness; the insert’s ISO CCMT09T308 designation and a thickness of 3.97 mm ensure interchangeability with standard CCMT toolholders. The single-side chipbreaker and the 0.8 mm corner make this insert suitable for stable external turning as well as internal boring where the holder offers sufficient support. For interrupted cuts or variable engagement, the CVD-coated carbide grade gives additional edge protection and toughness, supporting reliable cycle times and predictable reconditioning intervals.

FAQ

Which materials is this insert suitable for?
The CCMT09T308 in T9225 is optimised for medium to heavy steel machining and performs reliably under slightly interrupted cuts where additional toughness is required.

How does the CVD coating benefit the machining process?
A CVD-coated carbide insert like the T9225 reduces abrasive wear on the cutting edge, extending tool life and maintaining consistent surface finish during prolonged turning operations.

Can this insert be used for internal turning/boring?
Yes; the rhombic geometry and 0.8 mm corner radius make the insert suitable for internal turning where the holder provides adequate support and the working conditions match the grade’s capabilities.

What does the hole and countersink specification mean for clamping?
The cylindrical hole with single-side countersink (40°–60°) secures the insert in standard CCMT clamping systems, improving stability and repeatability during machining.

How to choose the right chipbreaker or holder for this insert?
Select the chipbreaker and holder according to the workpiece material, required surface finish and the stability of the setup; the insert’s single-side chipbreaker is a versatile choice for many turning tasks.
