CCMT09T304 AH725 Tungaloy indexable insert for turning — PVD-coated carbide, 0.4 mm radius

CCMT09T304 AH725 is an ISO-spec rhombic indexable insert designed for precision external and internal turning, offering a versatile, break-resistant grade for mixed material applications.

• PVD-coated carbide AH725 for versatility
• 0.4 mm nose radius for fine contours
• 7° clearance angle for stable cutting
• Rhombic CCMT form with securing hole

Consistent process security through optimised grade and coating

The combination of the AH725 PVD coating and a carbide substrate provides a balanced solution for varied turning tasks. The chosen grade is designed to be universal and break-resistant, which means fewer insert changes where workpieces alternate between softer and tougher steels. This leads to measurable improvements in uptime and reproducible component quality. The PVD coating reduces flank wear and improves edge stability, translating directly into more predictable tool life and lower tooling costs per part.

Geometry that delivers precision and repeatability

A 0.4 mm corner radius and a 7° clearance angle create a geometry well suited to finishing and light- to medium-duty roughing where surface quality and dimensional control matter. The CCMT rhombic shape allows the insert to be mounted in many standard external holders and boring bars while the 3.97 mm plate thickness contributes to rigidity under load. The central hole with a cylindrical bore and a single-sided countersink (40°–60°) ensures secure clamping and simple replacement; the secure fit reduces micro-movements that can affect concentricity and surface finish.

Practical system guidance for efficient setup

Used as part of a complete system — insert, compatible holder or boring bar, underpad/clamping kit and spare screws — this insert supports stable, repeatable turning operations. Select the single-sided chipbreaker variant to match workpiece material and machine stability; chip control is a key factor for uninterrupted production, particularly in automated or multi-operation setups. Where enhanced process security is required, pair the insert with a holder that matches form, clearance angle and tolerance class to ensure full compatibility and avoid seating errors.

Economical advantage and recommended applications

The AH725 grade is optimised for turning steel and stainless steel, making it suitable for mixed-production environments and operations where material batches vary. Its break-resistant nature reduces the risk of unexpected edge failure on smaller tools or in applications with intermittent cutting conditions. For shop floors seeking consistent performance without frequent insert swaps, this configuration offers a cost-effective compromise between wear resistance and edge toughness.

FAQ

What materials is this insert suitable for?
The CCMT09T304 AH725 Tungaloy indexable insert (SKU 6856764-Tungaloy) is intended primarily for steel and stainless steel applications; the AH725 grade offers versatility across varying steels and changing workpiece materials.

How does the AH725 PVD coating affect tool life?
The PVD coating on the AH725 grade reduces flank wear and improves edge stability, resulting in more predictable wear patterns and often longer effective tool life compared with uncoated grades in comparable conditions.

Which holders are compatible with this CCMT insert?
Compatibility depends on the holder's form, clearance angle, tolerance class, fixing method, size and thickness; select a holder designed for CCMT 09T304 inserts and confirm that the clamping screw and underpad match the insert’s hole style.

What is the benefit of the 0.4 mm corner radius?
A 0.4 mm corner radius offers a balance between edge strength and fine contouring capability, improving surface finish while retaining sufficient robustness for light- to medium-duty turning.

Can this insert be used for internal turning?
Yes, the rhombic CCMT form and the grade’s break-resistant properties suit both external and internal turning when paired with an appropriate boring bar or holder.
