TPMT 16T304 AH725 TPMT16T304-PS – Triangular turning insert, PVD-coated, Tungaloy

TPMT16T304-PS AH725 is a triangular, ISO‑standard insert designed for robust external and internal turning, offering a universal, fracture‑resistant grade for steel and stainless steels in industrial turning applications

• PVD-coated universal grade AH725
• PS chipbreaker for consistent chips
• ISO‑normed triangular insert 16 mm
• Cylindrical hole with 40°–60° countersink

Increased process reliability with a universal PVD grade

The PVD‑coated AH725 grade combines wear resistance and toughness to deliver stable chip formation and extended tool life in mixed‑material environments. The coating reduces flank and crater wear, while the substrate material provides toughness under interrupted cuts. For workshops managing varied components, the universal cutting grade minimises tool variations and supports higher machine uptimes by reducing tool changes and inventory complexity.

Consistent clamping and repeatable results

As an ISO‑normed triangular insert, the geometry and hole arrangement guarantee reliable seating in compatible holders; compatibility depends on form, clearance angle, tolerance class, fastening and thickness. The insert features a cylindrical hole with a one‑sided countersink (40°–60°) and a standard included angle of 60°, enabling secure clamping and repeatable positioning. These mechanical features support tighter tolerances and predictable results across production batches.

Optimised chip control and fine cutting detail

With the PS chipbreaker and a corner radius of 0.4 mm, the insert balances chip control and edge strength for finishing and medium cuts. The modest radius helps achieve consistent surface finishes while maintaining corner stability during radial engagement. The insert thickness of 3.97 mm and an inscribed circle size of 16 mm suit compact toolholders and smaller‑scale setups, making the grade especially practical where space and tool rigidity influence the cycle time and quality.

FAQ

What materials is this insert suitable for? The TPMT16T304-PS AH725 insert is formulated as a universal, fracture‑resistant grade intended primarily for steel and stainless steels, offering broad material coverage in turning.

How does the PS chipbreaker affect machining? The PS chipbreaker on the TPMT16T304-PS promotes controlled chip formation and evacuation, improving process security and reducing the risk of built‑up edge during turning.

Which holders are compatible with this ISO insert? Compatibility requires a matching triangular pocket with the correct tolerance class, clearance angle and fastening arrangement; the insert’s dimensions (16 mm inscribed circle, 3.97 mm thickness) and hole style must align with the holder specifications.

Is this insert suitable for finishing cuts? Yes, the combination of a 0.4 mm corner radius and the AH725 grade provides a balance of edge strength and finish capability, making it suitable for medium to fine finishing operations.

What does the AH725 grade offer compared with other grades? AH725 provides higher fracture resistance and stable chip control across varying steels, reducing the need for frequent grade changes and supporting consistent production across mixed batches.
