CCMT09T308 T9225 turning insert by Tungaloy — CVD-coated carbide for medium to heavy steel

The CCMT09T308 is an ISO-standard rhomboid turning insert designed for external and internal turning in steel applications, offering a balance of toughness and wear resistance for intermittent and variable engagement conditions.

• CCMT09T308 rhomboid insert for turning
• CVD-coated carbide grade T9225
• 0.8 mm corner radius, 7° clearance angle
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for medium to heavy steel

The CVD-coated carbide grade T9225 provides a robust universal solution for the machining of medium to heavy steel, combining surface protection with substrate toughness to resist chipping under interrupted cuts. This coating technology increases edge life while maintaining the mechanical strength of the carbide body, which translates into fewer indexings and longer production runs. The result is improved process stability and predictable tool life, which supports productivity and reduces unplanned downtime in serial turning operations.

Precise geometry and secure clamping for repeatable results

The rhomboid geometry with an 80° included angle, 0.8 mm corner radius and 7° clearance angle yields a stable cutting edge that supports consistent surface finish and dimensional control. A plate thickness of 3.97 mm and the cylindrical hole with a single-side countersink (40°–60°) ensure secure seating in ISO-compatible holders, lowering the risk of movement under load. These geometric attributes facilitate predictable cutting forces and vibration damping, which benefits both roughing passes and finishing cycles by improving repeatability across batches.

System compatibility and practical guidance for setup

As an ISO-indexable insert, the component forms part of a complete system that includes a suitable external holder or boring bar, underlay/clamping set and replacement fixing screws; compatibility is determined by shape, clearance angle, tolerance class, fixing method, size and thickness. The single-sided chipbreaker is matched to general turning tasks but should be selected according to workpiece material and machining stability for optimal chip control. For complex or variable machining conditions the combination of a robust universal grade and the correct chipbreaker reduces the likelihood of edge failure and supports continuous operation with predictable outcomes.

FAQ

What materials is this insert suited to machine? The CCMT09T308 with T9225 grade is intended primarily for medium to heavy steel machining and performs well under slightly interrupted cutting conditions.

How does the CVD coating benefit tool life? A CVD-coated surface on the Tungaloy insert enhances wear resistance while preserving substrate toughness, which increases edge life and reduces the frequency of indexings for continuous turning.

Which holders are compatible with this insert? Compatibility depends on holder form, clearance angle, tolerance class, fixing method, size and thickness; the CCMT09T308 is ISO-standard and fits holders designed for CCMT-format inserts.

What does the plate hole specification mean for clamping? The cylindrical hole with a single-side countersink (40°–60°) provides a secure seating and reliable clamp engagement, supporting repeatable positioning under cutting loads.

When should the single-sided chipbreaker be changed? The single-sided chipbreaker is suitable for general turning; selection should be reviewed when changing workpiece material, cut depth or if chip control issues arise during operation.

Is this an original Tungaloy product and what is the SKU? This is an original Tungaloy turning insert, listed under SKU 6781115-Tungaloy (manufacturer SKU TUN6781115).
