TPMT 110304 AH725 ISO turning insert, PVD-coated carbide, 60° triangle — Tungaloy

TPMT 110304 AH725 is a triangular, ISO‑standard indexable insert designed for general turning operations where process security and material versatility are required

• PVD-coated carbide AH725 for process security
• Universal grade for steel and stainless steel
• 60° triangular geometry for versatile turning
• 0.4 mm corner radius for fine finishing
• Centre hole with countersink (40°–60°) for fixation

Consistent chip control and reliable cutting performance

The PVD‑coated carbide grade AH725 is formulated for stable chip formation across a broad range of steels, including stainless steel, making it a safe choice for mixed‑material batches and reduced tool inventory. The PVD coating increases wear resistance and helps preserve the cutting edge under interrupted cuts; the combined effect is fewer tool changes and more predictable cycle times. For customers seeking repeatable results, the insert’s chipbreaker PS is matched to the grade to support controlled chip curl and evacuation, contributing directly to higher productivity and lower scrap rates.

Smooth integration into ISO tooling systems for quick changeovers

Being ISO‑standardised, the insert fits established ISO turning systems when the holder’s shape, clearance, tolerance class, fastening, size and thickness match the insert’s specifications. The geometry features a 60° triangle and an 11° clearance angle, while the plate thickness of 3.18 mm ensures robust seating in modern external holders and boring bars. The central hole combined with a cylindrical bore and single‑side countersink (40°–60°) provides secure clamping and repeatable positioning during high‑speed index changes. This compatibility reduces setup time and simplifies inventory management in mixed‑tool shops.

Geometry tuned for surface quality and small‑tool applications

A 0.4 mm corner radius enables a balance between strength and surface finish: small radii reduce cutting forces for fine finishing, while still offering sufficient edge support for light interruption and profiling. The 60° triangular form gives three indexed corners per insert, optimising cost per cutting edge for external turning and internal operations where smaller diameters or compact tooling is required. Specifying the correct chipbreaker and the AH725 grade helps prevent edge chipping on small tools, maintaining part tolerances and reducing rework.

Application guidance and selection advice for stable machining

Intended primarily for turning, the insert is suitable for both external and internal operations where a universal, fracture‑resistant grade is advantageous. The combination of AH725 and the PS chipbreaker is particularly recommended when material batches change or when process reliability is paramount. When integrating the insert into an existing toolchain, confirm holder compatibility by matching the ISO designation, thickness and seat geometry; if uncertainty remains, consult technical data or Metav Werkzeuge’s application experts for cutting data and holder recommendations. The model TPMT110304‑PS AH725 offers a pragmatic mix of durability and versatility for production and jobbing environments.

FAQ

What materials is this insert suitable for?
The AH725 PVD‑coated grade is intended for a wide material spectrum and is particularly suited to steel and stainless steel applications; its universal character supports changing workpiece materials without frequent insert exchanges.

How does the chipbreaker PS affect machining?
The PS chipbreaker promotes controlled chip formation and evacuation, reducing the risk of entanglement and improving surface finish during turning operations with the AH725 grade.

Which holders are compatible with this insert?
Compatibility depends on matching the ISO plate form, 3.18 mm thickness, seat geometry and fastening type; confirm the holder accepts TPMT‑style triangular inserts with a 11° clearance angle and central hole with countersink.

What benefits does the 0.4 mm corner radius offer?
A 0.4 mm radius provides a compromise between edge strength and surface quality, helping to achieve fine finishes while maintaining resistance to edge chipping in light interrupted cuts.

Is this an original Tungaloy product and which SKU should be ordered?
The product is an original Tungaloy indexable insert listed under SKU 6856678-Tungaloy and manufacturer item number TUN6856678; specify the ISO designation TPMT110304‑PS AH725 when ordering to ensure the correct grade and chipbreaker.
