TPMT 130304 AH725 triangular turning insert for ISO turning by Tungaloy

TPMT 130304 AH725 is an ISO-standard triangular indexable insert designed for general turning operations, offering universal, fracture-resistant performance for steel and stainless steels.

• ISO-standard triangular insert
• PVD-coated AH725 universal grade
• 0.4 mm nose radius for fine finishes
• Central hole with 40°–60° countersink

Reliable machining performance and process security

The triangular indexable insert delivers consistent results in external and internal turning thanks to the AH725 grade and a PVD-coated carbide substrate. The coating reduces flank wear and improves resistance to adhesion when machining steels and stainless steels, which helps maintain tool life and minimise unscheduled tool changes. The PSF chipbreaker is optimised for controlled chip formation under varying cut conditions; this stabilised chip control reduces the risk of insert breakage and supports reproducible cycle times on medium- to high-duty programmes. Compatibility with ISO holders ensures predictable clamping and repeatable reference positions in serial production.

Precision geometry for surface quality and versatility

A 0.4 mm nose radius combines a fine cutting edge for good surface finish with sufficient edge strength for light to moderate depths of cut. The insert’s 11° clearance contributes to reduced rubbing and improved tool-to-workpiece engagement, which in turn lowers cutting forces and heat generation. The triangular shape gives three usable cutting corners, improving cost-efficiency per index. Where a smoother finish is required, the small radius and the PVD layer work together to deliver finer surface results without sacrificing process reliability. For roughing, the same geometry provides stable performance when paired with appropriate feeds and depths.

Compatibility, handling and set-up explained

The insert is an ISO-design plate with a central fastening hole — a cylindrical hole with a one-sided countersink (40°–60°) — that matches standard clamping systems and replacement screws. The plate thickness of 3.18 mm and plate size 13 mm align with common ISO holders; these dimensions determine insert stiffness and heat capacity during cutting. The insert’s universal, fracture-resistant nature reduces inventory complexity: one grade covers multiple steel types and small tools where process security is paramount. When selecting a holder, match form, free angle, tolerance class, fastening method, size and thickness to guarantee correct seating and consistent repeatability.

FAQ

Which materials is this insert suitable for? This TPMT 130304 AH725 insert by Tungaloy is designed as a universal, fracture-resistant grade for machining steels and stainless steels, making it suitable for a wide range of turning applications.

What does the AH725 grade offer compared with other grades? The AH725 grade provides a balance of wear resistance and toughness; for the TPMT 130304 AH725, this means improved process security and wider material coverage compared with narrowly specialised grades.

How does the 0.4 mm nose radius affect machining? A 0.4 mm nose radius on the insert offers a compromise between surface finish and edge strength, allowing finer finishes at moderate feeds while maintaining resistance to chipping under intermittent cuts.

What is the purpose of the central hole and countersink? The cylindrical centre hole with a one-sided countersink (40°–60°) enables secure fastening in standard clamping systems, ensuring correct seating and repeatable reference for serial production.

Can the insert be used for finishing and semi-finishing? Yes, the combination of the small nose radius, PVD-coated carbide and PSF chipbreaker makes the insert suitable for finishing and semi-finishing when matched with appropriate feeds and speeds.
