TPMT 16T308 T9225 ISO triangular insert for turning (CVD-coated carbide, 0.8 mm radius) — Tungaloy

TPMT16T308-PSS T9225 is an ISO-standard triangular indexable insert optimised for external and internal turning, offering a robust universal grade for medium to heavy steel machining.

• CVD-coated carbide grade T9225
• Universal for medium to heavy steel turning
• Triangular ISO insert, 16 mm size
• 0.8 mm corner radius, 11° clearance

High-performance grade for demanding steel turning

The combination of a CVD-coated carbide substrate and the T9225 grade provides a balance of hardness and toughness suited to medium to heavy steel machining. This results in improved resistance to edge chipping under changing engagement conditions and during slightly interrupted cuts. The technical choice of coating and substrate reduces flank wear and helps maintain a consistent surface finish, which supports longer intervals between indexings and reduces process variability.

Predictable geometry for repeatable results

Engineered as an ISO-standard triangular insert, the geometry ensures interchangeability with compatible holders; compatibility depends on form, 11° clearance angle, tolerance class, fastening and the insert’s thickness. The 0.8 mm corner radius helps deliver a stable cutting edge for shoulders and general turning, while the 60° included angle gives reliable negative or positive clamping options depending on toolholder selection. These geometric parameters translate into predictable component tolerances and easier process setup on production lathes.

Practical system integration and mounting

The insert is designed to be used within a complete insert system consisting of the indexable insert, an appropriate external holder or boring bar, a shim/clamping set and replacement screws. The 16 mm size and 3.97 mm thickness are standard dimensions that ease procurement and holder selection. The insert features a cylindrical hole with a one-sided countersink (40°–60°), enabling secure fastening and stable seating that reduces vibration and supports higher metal removal rates when combined with suitable tooling.

Application guidance and efficiency gains

Choose the chipbreaker PSS and the T9225 grade when machining steels that require a compromise between wear resistance and toughness, particularly where feeds and depths vary or when light interruptions occur. Proper selection of speeds, feeds and coolant strategy will exploit the insert’s properties, allowing for increased cutting volumes and consistent part quality. The result is an efficient machining step that supports throughput without compromising repeatability.

FAQ

What materials is this insert best suited for? The TPMT16T308-PSS T9225 is specified for medium to heavy steel machining; the CVD-coated carbide grade T9225 balances wear resistance and toughness for such applications.

How does the chipbreaker affect machining? The PSS chipbreaker on the insert controls chip formation for stable evacuation and reduced risk of built-up edge during turning with the T9225 grade.

Which toolholders are compatible with this ISO insert? Compatibility is determined by holder form, clearance angle, tolerance class, fastening method, size and thickness; select a holder designed for TPMT 16T308 geometry and the 3.97 mm thickness.

Can this insert handle interrupted cuts? Yes, the T9225 grade is formulated to offer increased toughness for light to moderate interruptions, helping to avoid edge chipping compared with harder but more brittle grades.

What is the mounting arrangement for secure clamping? The insert uses a cylindrical centre hole with a one-sided countersink (40°–60°) to allow reliable seating and clamping with the appropriate screws and shim/clamping set supplied in the insert system.
