TPMT 16T304 AH725 — Turning indexable insert, PVD‑coated carbide, 0.4 mm radius (Tungaloy)

TPMT 16T304 AH725 is a triangular ISO insert for general turning, designed to deliver stable cutting performance across steels and stainless steels in both external and internal operations.

• ISO triangular insert TPMT format
• PVD‑coated carbide grade AH725
• 0.4 mm corner radius for versatile turning
• Cylindrical hole with 40°–60° countersink

High process security and broad material coverage

The TPMT16T304-PSS AH725 is built on a PVD-coated carbide substrate and the AH725 grade, engineered as a chipbreaker-compatible solution for mixed‑material shops. Its composition provides process security during interrupted cuts and variable conditions, which reduces the risk of edge failure and unplanned stops. For turning applications, this combination supports consistent tool life and a reliable balance between wear resistance and toughness when machining steel and stainless steel, making it a sound choice where material mix and repeatability matter.

Secure seating and standardised fit for rapid indexability

As an ISO conforming triangular insert it is shaped for repeatable clamping and quick indexing. The geometry includes an 11° relief, a plate 3.97 mm thickness, and a cylindrical hole with a single‑side countersink (40°–60°), which together ensure accurate positioning and stable fixation in the holder. These features minimise vibration and help maintain a stable cutting edge during higher feeds, reducing set‑up time and improving overall uptime in production environments where consistent clamping and straightforward insert replacement are required.

Optimise edge form for surface finish and productivity

A 0.4 mm radius offers a versatile edge that supports both finishing and moderate profiling tasks with good surface quality while preserving cutting edge robustness. The PVD layer enhances wear resistance, extending usable tool life under varied cutting conditions and permitting higher productivity through longer cycles between indexings. Select the PSS chipbreaker and adjust speeds and feeds to match part rigidity and toolholder stability; for smaller tooling or demanding process stability, this insert's balance of edge strength and coating performance delivers measurable gains in machining reliability.
