*Universal for Stahl and rostfreier Stahl
*Rhombic ISO CCMT 09, 0.8 mm corner radius
*Cylindrical hole plus single-side countersink

Optimise process reliability with a universal PVD grade

The AH725 grade is a PVD-coated carbide formulated for broad applicability across Stahl and rostfreier Stahl, giving a stable cutting edge where material mixes are common. The coating improves wear resistance while the substrate maintains toughness, which together reduce the risk of edge breakouts in smaller tools or less rigid setups. This combination delivers a noticeable improvement in process security and makes the insert suitable for shops that require predictable tool life across varied turning tasks.

Geometry that delivers consistent chip control and surface quality

The insert's rhombic shape in CCMT 09 format, combined with a 0.8 mm corner radius and an 80° main angle, provides a versatile contact geometry that supports both finishing and light roughing operations. A one-sided chipbreaker promotes reliable chip formation and evacuation, lowering the chance of re-cutting and improving surface finish consistency. The 7° clearance angle further helps reduce rubbing and thermal build-up, translating into stable cutting conditions and fewer interruptions for tool change.

Compatible system design and straightforward integration

Designed as an ISO indexable insert, the component integrates into standard holder systems where compatibility is defined by form, clearance angle, tolerance class, fastening and plate thickness. The insert is supplied with a cylindrical hole and a single-side countersink (40°–60°), simplifying secure clamping in compatible carriers. Using a universally engineered grade and standardised dimensions reduces set-up complexity, shortens downtime during changeover and supports a more economical machining routine over time.

FAQ

Which materials are best suited to this insert?
The CCMT09T308 AH725 indexable insert from Tungaloy is designed for machining a wide range of materials, specifically Stahl and rostfreier Stahl, offering a good compromise between wear resistance and toughness.

How does the AH725 grade affect tool life?
The AH725 PVD coating enhances wear resistance while the carbide substrate provides edge strength; together they promote consistent tool life and reduced edge chipping in mixed-material production.

Is the insert compatible with standard CCMT holders?
Compatibility depends on holder form, clearance angle, tolerance, fastening and plate thickness; the CCMT format and hole/countersink design are standard for many CCMT holders, but verification against the holder specification is recommended.

What cutting applications suit the one-sided chipbreaker?
The one-sided chipbreaker is suitable for both finishing and light to medium turning where controlled chip formation and safe evacuation are required, improving surface quality and process stability.

Can this insert be used for internal turning as well as external turning?
Yes — the geometry and breakage-resistant AH725 grade make the insert applicable for both external and internal turning operations when matched with an appropriate holder.
