CPMT 09T304 AH725 — Indexable turning insert for turning by Tungaloy

CPMT 09T304 AH725 is an ISO‑standard rhombic insert designed for external and internal turning in general workshop and production environments.

• ISO‑standard geometry, rhombic shape
• PVD‑coated cemented carbide AH725
• Single‑sided chipbreaker for controlled chips
• 11° clearance angle, compatible with ISO holders

Reliable performance for mixed‑material turning

The PVD‑coated cemented carbide grade AH725 delivers a balance between toughness and wear resistance, making the insert suitable for machining both medium steel and stainless steels in variable production runs. The PVD layer improves surface hardness and reduces flank wear, which translates into longer tool life and fewer indexings. Compared with uncoated grades, this coating offers improved resistance to built‑up edge and thermal softening, helping to maintain dimensional stability during continuous turning operations.

Precision geometry that enhances process security

With an 80° main angle and a rhombic form, the insert provides a stable cutting edge for general turning tasks while offering good access for finishing passes. The 0.4 mm corner radius supports a compromise between edge strength and surface finish; a larger radius improves durability, while this moderate radius still permits fine surface quality. The 11° clearance angle reduces rubbing on the flank and helps sustain consistent cutting forces, which is particularly important when working with shorter, less rigid setups. This geometry contributes directly to predictable tool behaviour and fewer scrapped parts.

Controlled chip formation and mounting reliability

The one‑sided chipbreaker design supports effective chip control for common turning feeds and depths, reducing the risk of chip entanglement and promoting safer machine handling. The insert is supplied with a central hole featuring a cylindrical bore and a single‑sided countersink (40°–60°), ensuring secure clamping in compatible ISO indexable holders or turning bars. Correct clamping, determined by form, clearance angle, tolerance class, fixing method, size and thickness, is essential for achieving the process reliability expected from production tooling.

Practical selection and versatility in everyday production

As part of an ISO turning insert series, compatibility is straightforward when matching holders and underlay kits by ISO specifications. The universal, fracture‑resistant nature of this grade makes the insert a practical choice where batches include a variety of steels or when smaller tool sizes are required. Choosing a grade like AH725 reduces the need for frequent grade changes, supporting quicker setup times and a more economical production flow while maintaining consistent surface quality.

FAQ

What materials is this insert designed for? The CPMT 09T304 AH725 insert is designed primarily for steel and stainless steels; the AH725 grade provides a universal, fracture‑resistant performance across these materials.

How is the insert clamped in the holder? Clamping is achieved via the central hole (cylindrical with a single‑sided countersink) and the insert form; correct holder selection according to ISO dimensions ensures secure fixation and repeatable positioning for the CPMT 09T304 AH725 insert.

Can this insert be used for finishing and roughing operations? The geometry and 0.4 mm corner radius favour general turning and finishing passes; while the grade is robust enough for light roughing, heavier stock removal may require a different geometry or a larger radius to optimise edge life.

What advantage does the PVD coating provide? The PVD coating on the AH725 grade increases surface hardness and reduces flank wear and built‑up edge, which supports longer tool life and consistent surface quality during continuous turning operations.

Is this insert compatible with all ISO turning holders? Compatibility depends on matching the insert form, free angle, tolerance class, fixing method, size and thickness to the holder; the CPMT 09T304 follows ISO standards, so selection of a matching ISO holder or turning bar is recommended.
