TPMT130308-PM AH725 — ISO turning insert, triangular 60°, PVD-coated (Tungaloy)

The TPMT130308-PM AH725 is an ISO-standard turning insert designed for external and internal turning, optimised for steel and rostfreier Stahl applications.

• ISO triangular insert 60° geometry
• PVD-coated carbide grade AH725
• 0.8 mm nose radius for precise finishing
• Cylindrical hole with 40°–60° countersink

Stable productivity for demanding turning tasks

The insert's PVD-coated carbide composition and the AH725 grade deliver a balance of wear resistance and fracture toughness that supports consistent cycle times. Designed as a universal, fracture-resistant grade for Stahl and rostfreier Stahl, this specification reduces unexpected tool failures and minimises interruptions. In practice, that means more predictable machining windows and fewer unplanned indexings, which contributes directly to improved throughput and lower process variation in batch production.

Reliable surface quality with economical tool life

With a 0.8 mm nose radius and a 60° triangular geometry, the insert provides a good compromise between edge strength and fine surface finish. The 11° relief angle reduces rubbing on the flank, while the PM chipbreaker promotes controlled chip formation when turning a range of materials. For shops processing mixed batches, the combination of edge geometry and chip control means fewer tool changes and more consistent part quality, translating into both time savings and reduced rework.

ISO compatibility for straightforward integration

The insert follows ISO standards for indexable turning plates; compatibility with holders is determined by form, relief angle, tolerance class, fastening, size and thickness. The plate thickness of 3.18 mm and plate size 13 mm match common external holders, and the cylindrical hole with single-side countersink (40°–60°) ensures secure clamping. The recommended system build includes the ISO insert, a matching external holder or boring bar, a backing/clamping set and spare screws, enabling quick integration into existing tool systems with minimal adjustments.

Practical advantages for workshop decision-making

Choosing this insert supports flexible machining strategies: it performs well on both roughing and finishing operations when matched with appropriate cutting parameters and workpiece stability. The PVD coating provides thermal protection at higher cutting speeds, making it suitable for many general turning tasks. For engineers and buyers, the clear specification of geometry, coating and grade simplifies cost-benefit assessments and helps to standardise tooling across multiple machines and operators.

FAQ

What materials is this insert suitable for?
The TPMT130308-PM AH725 is specified for machining Stahl and rostfreier Stahl and performs well across a broad range of common turning materials when paired with the correct cutting data.

Which chipbreaker is fitted and what does it do?
The insert uses a PM chipbreaker; this promotes controlled chip formation and improves process reliability during both roughing and finishing cuts.

How does the AH725 grade influence tool life?
AH725 is a PVD-coated, fracture-resistant carbide grade that balances wear resistance and toughness to provide reliable tool life under varying workpiece conditions.

Is the insert compatible with standard ISO holders?
Yes. The TPMT130308-PM follows ISO plate dimensions; compatibility depends on form, relief, tolerance class, fastening method, plate size and thickness—ensure the holder matches these parameters.

What are the mounting details for secure clamping?
The insert has a cylindrical hole with a single-side countersink (40°–60°) for stable fastening; use the correct backing/clamping set and replacement screws as part of the system.
