TPMT 110204 AH725 — ISO triangular turning insert, PVD-coated carbide, 11° clearance (Tungaloy)

TPMT110204 AH725 is an ISO-indexable turning insert engineered for external and internal turning, offering a universal, breakout-resistant carbide grade for steel and stainless steels.

• Universal PVD-coated carbide AH725
• 11° clearance for stable cutting
• Triangular ISO shape, 11 mm size
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance with a universal PVD grade

The AH725 grade is a PVD-coated carbide engineered for reliable performance across a wide range of steels and stainless steels. Its composition and coating combination provide stable chip formation and reduced edge chipping under changing material conditions, so fewer unplanned interruptions occur. The insert’s small 0.4 mm corner radius helps deliver predictable engagement and fine surface finishes when light cuts are required, while the PVD coating supports wear resistance in intermittent turning. These attributes translate into higher process uptime and reduced tool change frequency, which benefits batch production and mixed-material workflows.

Fast, secure clamping and ISO compatibility for reliable set-up

Designed to ISO standards, the triangular geometry and defined dimensions make holder selection straightforward; compatibility depends on the insert’s shape, 11° clearance, tolerance class, attachment style, size and thickness. The cylindrical hole with a 40°–60° countersink provides secure seat and concentric clamping, reducing vibration and maximising repeatability from cut to cut. With a plate thickness of 2.38 mm and an inscribed circle of 11 mm, the insert fits small external and internal holders where compactness and rigidity are necessary. Clear mechanical interfaces shorten set-up times and support consistent machining results even in short-production runs.

Practical selection guidance for turning applications

For typical external and internal turning, pair the insert’s one-sided chipbreaker with an appropriate feed and depth of cut to match workpiece stability and the chosen operation. The universal character of the grade makes it a sensible choice when material mixes occur or when using smaller toolholders with limited overhang. Selecting this insert reduces the need for multiple specialised grades, while the ISO triangular form and defined nose radius allow controlled material removal and good surface integrity. When process security and predictable tool life are priorities, this insert offers a balanced solution between performance and economy for everyday turning tasks.

FAQ

What materials is this insert suitable for?
The TPMT110204 AH725 insert is designed as a universal solution and is suitable for machining steel and stainless steels, thanks to the PVD-coated carbide grade.

What is the inscribed circle and why does it matter?
The insert has an inscribed circle of 11 mm, which defines the compatible toolholder size and affects rigidity and chip evacuation during turning.

How does the 0.4 mm corner radius influence the cut?
A 0.4 mm corner radius gives a controlled cutting edge for fine finishes and reduced notch sensitivity, useful when consistent surface quality is required.

What clamping style does the insert use?
This insert features a cylindrical hole with a single-sided countersink (40°–60°), providing secure and repeatable clamping in compatible ISO holders.

Can this insert be used for both external and internal turning?
Yes, the insert is suitable for both external and internal turning; select the chipbreaker and cutting parameters according to workpiece stability and required surface finish.
