CPMT 09T304 T9225 indexable insert for turning — Tungaloy

The CPMT 09T304 is an ISO rhombic turning insert designed for robust external and internal turning of steel, combining a T9225 universal grade with a CVD coating for stable performance under varying cut conditions.

• CVD-coated carbide grade T9225 for robustness
• Rhombic 09 form with 11° rake angle
• One-sided chipbreaker for medium to heavy cuts
• Central hole with cylindrical countersink mounting

Increased machining reliability through material and grade

The combination of CVD coating and a carbide substrate provides a balance of wear resistance and toughness. The T9225 grade is formulated as a universal solution for medium to heavy steel machining where intermittent cuts or variable engagement demand additional toughness. This results in fewer insert changes and steadier production output, while the CVD-coated surface reduces flank wear and helps maintain dimensional accuracy over longer tool life.

Clear compatibility and secure clamping for predictable set-up

Compatibility with the toolholder is determined by the insert’s shape, clearance angle, tolerance class, clamping method, size and thickness. The rhombic 09 form and the central hole with a cylindrical countersink (40°–60°) allow straightforward seating and repeatable clamping on standard ISO toolholders. The insert’s 11° free angle and 0.4 mm corner radius support geometry choices that balance edge strength with surface finish, making the component suitable for a wide range of turning operations.

Practical benefits: chip control and productivity

A one-sided chipbreaker is integrated to improve chip formation during medium to heavy cuts, reducing the risk of built-up edge and improving swarf evacuation. Better chip control lowers cycle interruptions and enhances operator safety, while the CVD-coated carbide helps extend tool life under higher thermal loads. Together, these features support more productive machining, fewer tool changes and a lower total cost per part in demanding steel turning tasks.

FAQ

What materials is this insert intended for?
The CPMT09T304 T9225 insert from Tungaloy is intended primarily for steel applications and performs well in medium to heavy turning operations.

How does the T9225 grade affect tool life?
The T9225 grade, with its CVD coating, increases wear resistance and toughness, which together help extend the service life of the CPMT09T304 during interrupted or variable cuts.

Which toolholders are compatible with this insert?
Compatibility depends on insert shape, clearance angle and clamping method; the rhombic form and central hole of the CPMT09T304 allow mounting in standard ISO toolholders designed for 09-size rhombic inserts.

What chip control can be expected with this geometry?
The one-sided chipbreaker integrated into the insert promotes stable chip formation for medium to heavy cuts, improving swarf evacuation and reducing machining interruptions.

Is the insert suitable for finishing passes?
While optimised for medium to heavy turning, the CPMT09T304 can be used for finish passes if cutting parameters and tool geometry are adjusted to prioritise surface quality.
