TPMR 160304 AH725 Turning Insert — ISO triangular, PVD-coated carbide (Tungaloy)

TPMR 160304 AH725 is a triangular, ISO-standard turning insert designed for external and internal turning; suitable for demanding, variable-material applications where process reliability is essential.

• PVD-coated carbide, AH725 universal grade
• ISO-standard triangular insert for turning
• 11° clearance angle for stable cutting
• 0.4 mm nose radius with single-sided chipbreaker

Consistent performance with a universal PVD grade

The AH725 grade combines a PVD-coated surface with a robust carbide substrate to deliver extended tool life and predictable wear behaviour. This universal grade is formulated for machining both steel and stainless steel, giving high process security across mixed production batches. The coating reduces built-up edge and improves surface finish; the result is fewer stoppages for insert changes and a more uniform part quality. For operations that require repeatable results on small holders or where workpiece material varies, this grade minimises unexpected tool failure and supports stable cycle times.

Geometry and system compatibility that support accuracy

The insert’s ISO designation and triangular form ensure straightforward integration with standard holders; compatibility is governed by form, clearance angle, tolerance class, fastening method, size and thickness. With an 11° clearance angle and a 0.4 mm nose radius, the geometry balances robustness and detail: the clearance reduces rubbing and heat, while the nose radius contributes to surface integrity and vibration dampening. The thickness of 3.18 mm and the 60° included angle provide rigidity in the cutting zone. These parameters are selected to maintain dimensional accuracy and reduce chatter in both external and internal turning tasks.

Practical integration and chip control for daily production

The insert is supplied without a hole and features a single-sided chipbreaker, making it suitable for many standard clamping systems and for operators who need consistent chip formation. The system build normally includes a matching external holder or boring bar, a backing/support set and replacement clamping screws; correct pairing is essential for secure clamping and repeatable results. By choosing the appropriate chipbreaker and the AH725 grade for mixed-material runs, the indexable insert supports safer, more economical machining and reduces rework. Production planners will value the predictability and the reduced need for ad hoc adjustments during shifts.

FAQ

What materials is this insert suitable for?
The AH725 grade is geared towards steel and stainless steel machining; the TPMR 160304 insert provides reliable chip control and wear resistance when these materials are processed.

Can this insert be used for internal turning as well as external turning?
Yes, the triangular ISO form and the specified geometry make the insert suitable for both external and internal turning operations when paired with an appropriate holder.

How is compatibility with holders determined?
Compatibility depends on insert form, clearance angle, tolerance class, fastening type, size and thickness; the ISO designation simplifies selection of a matching external holder or boring bar.

What are the advantages of the AH725 PVD coating?
The PVD layer improves thermal resistance, reduces adhesion of workpiece material and stabilises the cutting edge, which leads to longer life and fewer interruptions in production when using the AH725 grade.

Is the chipbreaker suitable for mixed-material production?
The single-sided chipbreaker offers consistent chip formation for many turning scenarios; selecting the correct chipbreaker and grade helps maintain process security across varying workpiece materials.
