TPMT 16T304 T9225 triangular indexable turning insert — CVD-coated carbide, chipbreaker PSF — Tungaloy

TPMT 16T304 T9225 is a triangular ISO turning insert designed for external and internal turning of steel where medium to heavy cuts and intermittent engagement demand increased toughness

• CVD-coated carbide grade T9225
• Robust universal grade for medium-heavy steel
• Chipbreaker PSF for stable chip control
• 60° triangle with 0.4 mm corner radius

Consistent productivity through a balanced carbide grade

The CVD-coated carbide composition of this insert, combined with the T9225 grade, provides a deliberate balance between wear resistance and fracture toughness. This balance is particularly beneficial in production environments where cutting conditions vary or where interrupted cuts are frequent. The result is fewer index changes and longer effective tool life, which lowers machine downtime and contributes to a more economical turning process. The robust specification supports higher material removal rates in steel while still maintaining surface quality.

Design features that ensure secure clamping and accurate geometry

The insert's triangular form with a 60° included angle and a corner radius of 0.4 mm gives both versatility and strength for a range of turning tasks. The relief angle of 11° and the plate thickness of 3.97 mm ensure correct seating and load distribution in ISO-compatible holders. The central cylindrical hole with a single-side countersink (40°–60°) supports standard clamping systems and simplifies replacement. Compatibility to specific holders is determined by form, clearance angle, tolerance class, clamping method, size and thickness; confirming these parameters avoids misfits and secures repeatable machining accuracy.

Chip control and practical application guidance

The integrated chipbreaker PSF is engineered to produce predictable, short chips when machining steels, improving evacuation and reducing the risk of entanglement on the workpiece or toolpost. For medium to heavy steel turning, select feeds and speeds according to job stability: a tougher grade like T9225 allows slightly more aggressive parameters than purely wear-focused grades, especially when cuts are intermittent. Where surface finish is critical, moderate feeds and appropriate nose radii will balance finish with productivity. The insert’s construction aids consistent chip formation across typical external and internal turning operations.

Reliability, handling and selection advice for production shops

As an ISO-standard turning insert from Tungaloy, TPMT 16T304 T9225 fits into established tooling systems and supports streamlined inventory management. The CVD-coated carbide layer improves resistance to abrasive wear while the substrate maintains fracture strength during variable engagement. When selecting inserts, match the chipbreaker, grade, and corner radius to the workpiece material and process stability; this reduces scrap risk and increases first-pass accuracy. For assistance with holder compatibility or process optimisation, Metav Werkzeuge provides technical advice to align insert choice with production goals.

FAQ

What materials is this insert suited for?
The TPMT 16T304 T9225 insert is designed primarily for steel machining; its T9225 grade provides toughness suited to medium and heavy steel turning operations.

Which chip form can be expected with the PSF chipbreaker?
The chipbreaker PSF produces controlled, short chips under typical steel turning conditions, improving evacuation and reducing the chance of chip-related interruptions.

How does the CVD coating benefit tool life?
The CVD-coated carbide layer increases abrasive wear resistance while the substrate maintains impact toughness, resulting in a longer effective life in variable cutting conditions.

Is this insert compatible with ISO holders?
This insert conforms to the ISO indexable insert system; compatibility depends on holder form, clearance angle, tolerance class, clamping and size — checking these parameters ensures correct fit.

What is the manufacturer SKU for ordering and reference?
The product is listed under SKU 6781224-Tungaloy and manufacturer SKU TUN6781224 for procurement and inventory purposes.
