TPMT 090208 AH725 – Tungaloy triangular turning insert, 60°, PVD-coated carbide

The TPMT 090208 AH725 is an ISO triangular indexable insert for turning, designed for reliable machining of steel and rostfreier Stahl with a one-sided chipbreaker for controlled chip formation.

• PVD-coated carbide AH725 for universal use
• Triangular 60° insert for versatile turning
• 0.8 mm corner radius for fine finishing
• Countersunk hole for secure clamping

Consistent cutting performance across mixed steels

The PVD-coated carbide grade AH725 delivers a balance of hardness and toughness that supports stable cutting on a wide range of steels, including rostfreier Stahl. The PVD coating increases surface hardness and thermal resistance, reducing flank wear at elevated temperatures and extending edge life. For shops processing varied workpiece materials, this combination translates into fewer indexings and more predictable cycle times, enhancing overall productivity without compromising surface quality.

Secure clamping and straightforward compatibility

The triangular geometry with a countersunk hole and 40°–60° single-sided countersink provides positive seating and repeatable clamping in compatible holders. Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; the standardised ISO shape ensures interchangeability with ISO-compliant external holders and boring bars. A stable clamping interface reduces vibration and enables consistent cutting forces, which is particularly beneficial when using smaller tools or machines with limited rigidity.

Improved process security and chip control

Equipped with a one-sided chipbreaker, the insert supports controlled chip formation and evacuation during turning operations. The AH725 grade is described as outburst-resistant, meaning it is engineered to resist edge chipping under interrupted cuts and varying cutting conditions. This focus on process security is valuable in batch production or mixed-run environments where reproducible results and reduced scrap rates matter. The result is predictable tool life and fewer unscheduled tool changes.

Compact dimensions for precision finishing and general turning

The insert’s 0.8 mm corner radius is well suited to produce fine surface finishes while retaining adequate edge strength for light to moderate depths of cut. With a plate thickness of 2.38 mm and a plate size designation of 09, the geometry is compact yet robust for general external and internal turning tasks. The 11° relief angle and the 60° cutting angle provide favourable cutting engagement for a wide range of turning operations; selecting the appropriate chipbreaker and cutting parameters will further optimise material removal and surface quality.

FAQ

What materials is this insert suited to machine?
The TPMT 090208 AH725 grade is formulated for machining a broad range of steels and rostfreier Stahl, offering reliable wear resistance and reduced chipping.

How does the PVD coating benefit tool life?
The PVD coating on the insert increases surface hardness and thermal resistance, which helps the cutting edge retain its geometry longer under higher temperatures and abrasive conditions.

Which holders are compatible with this insert?
Compatibility is determined by insert form, relief angle, tolerance class, fastening, size and thickness; use ISO-compliant turning holders or boring bars matched to the TPMT 090208 geometry.

What is the advantage of the one-sided chipbreaker?
The one-sided chipbreaker promotes controlled chip formation for many turning tasks, improving chip evacuation and contributing to process security during continuous or interrupted cuts.
