TPMT 110202 AH725 triangular indexable insert for turning — Tungaloy

The TPMT 110202 AH725 is an ISO-standard triangular indexable insert designed for external and internal turning, offering a universal PVD-coated carbide grade optimised for steels and stainless steels.

• Universal PVD-coated carbide grade AH725
• ISO triangular form for standard holders
• 0.2 mm nose radius for fine finishes
• Cylindrical hole with 40°–60° countersink

Consistent metal removal with a universal, process-secure grade

The PVD-coated AH725 grade combines wear resistance and fracture toughness to deliver process reliability across a wide range of steels and stainless steels. As a PVD-coated carbide insert with the PS chipbreaker, it is aimed at turning operations where material mix or small-tooling setups demand robust, repeatable performance. The combination of the AH725 coating and the chip control geometry reduces the risk of unexpected tool failure and supports longer effective tool life, which benefits cycle-time stability on production batches.

Geometry tuned for surface quality and repeatable clamping

The triangular shape and the 0.2 mm nose radius are configured to balance edge strength with the ability to achieve fine surface finishes on external and internal features. The 11° clearance minimises rubbing while maintaining cutting edge support; the 2.38 mm plate thickness contributes to rigidity for interrupted cuts. The insert's central cylindrical hole with single-side countersink (40°–60°) ensures reliable seating and torque transmission in common ISO clamping systems, reducing the chance of index shift during high-stability turning tasks.

ISO compatibility and practical application guidance for turning

This insert belongs to the ISO turning indexable insert family and is compatible with holders that match the insert form, clearance, tolerance class, attachment and thickness. A typical system comprises the insert, a matching external holder or boring bar, a shim/clamp set and replacement screws. Select the PS chipbreaker and the AH725 grade when machining a mix of steels or when process security is the priority; for highly stable setups aiming solely at maximum metal removal, alternative chipbreaker geometries may be considered. The insert is suitable for both finishing and medium-turning operations where controlled chips and repeatable seating are required.

Practical benefits and selection advice for production use

Using a universally tough, PVD-coated insert reduces tool inventory complexity while maintaining surface quality and dimensional stability in turning operations. The triangular form provides three indexing edges per insert, improving cost efficiency per cutting edge. When changing holders or adapting to different machine setups, verify holder compatibility by checking form and size details; correct match prevents misclamping and preserves the insert life and process reproducibility.

FAQ

What materials is this insert suitable for?
The TPMT 110202 AH725 insert is intended primarily for steels and stainless steels; the AH725 PVD-coated carbide grade provides a balance of toughness and wear resistance for mixed-material turning.

How does the PS chipbreaker affect cutting?
The PS chipbreaker on this insert promotes controlled chip formation and evacuation in a range of turning conditions, improving process security and reducing the likelihood of built-up edge on the cutting face.

Which holders are compatible with this ISO designation?
Compatibility depends on matching the insert form, clearance, tolerance class, attachment, size and thickness; the TPMT110202-PS format fits ISO-standard triangular holder types designed for this size designation.

What is the benefit of the 0.2 mm nose radius?
A 0.2 mm nose radius provides a compromise between edge strength and surface finish capability, allowing fine finishes on external features while maintaining adequate edge robustness for light interruptions.

How many cutting edges are available per insert and what is the plate thickness?
The triangular geometry offers three indexing edges per insert and a plate thickness of 2.38 mm, supporting rigidity in typical turning operations.
