CCMT120404 AH725 Turning Insert (CCMT) by Tungaloy — PVD-coated carbide, 0.4 mm radius

The CCMT120404 AH725 is an ISO-standard rhombic turning insert designed for general-purpose external and internal turning where process security and reliable chip control are required

• PVD-coated carbide grade AH725
• ISO CCMT 120404 rhombic format
• Suitable for steel and stainless steels
• 0.4 mm corner radius, single-sided chipbreaker

Consistent performance for mixed steel applications

The PVD-coated carbide composition of this insert offers a balance of wear resistance and edge toughness; this makes it particularly suitable for machining steel and stainless steels where material mixes or shorter batch runs occur. The AH725 grade is engineered for process reliability: the coating reduces adhesive wear while the substrate maintains a robust cutting edge. As a result, operators benefit from fewer interruptions and more predictable tool life, which contributes directly to improved productivity and lower overall machining cost per component.

Precise geometry that simplifies holder selection and setup

Compatibility with standard toolholders is determined by form, relief angle, tolerance class, fixing method, size and thickness; the rhombic CCMT format and the 7° relief angle ensure stable contact and repeatable clamping. The insert is supplied with a cylindrical hole plus one‑side countersink (40°–60°) that matches common clamping systems, while the plate thickness of 4.76 mm and 12 mm inscribed size provide a compact, rigid package. Clear reference to these dimensions enables straightforward selection of a matching holder and reduced trial-and-error during setup, helping to shorten machine idle time.

Practical benefits for everyday turning operations

Designed for both external and internal turning, the single-sided chipbreaker and the 0.4 mm corner radius combine to offer controlled chip formation and enhanced edge strength in interrupted cuts or variable feeds. This geometry supports consistent surface finish and dimensional stability in small to medium-sized tools where vibration and tool overhang can be factors. The ISO-standard format simplifies stock management and tool change routines, while the universal nature of the grade minimises the need for multiple specialised inserts—helping workshops maintain flexibility without sacrificing process security.

FAQ

What materials is this insert suitable for?
The CCMT120404 AH725 insert is formulated for machining steel and stainless steels, providing a balance of wear resistance and edge strength for mixed-material workshops.

How is compatibility with toolholders ensured?
Compatibility depends on holder form, relief angle, tolerance class, fixing method, size and thickness; the CCMT120404 format, 4.76 mm thickness and the hole/countersink arrangement match common ISO holders.

What coating and substrate does the insert use?
This indexable plate features a PVD-coated carbide substrate in the AH725 grade, designed to reduce adhesive wear and maintain a stable cutting edge under varying conditions.

What advantages does the 0.4 mm corner radius provide?
A 0.4 mm corner radius increases edge strength and supports interrupted cuts and variable feed rates while helping to produce consistent surface finishes in general turning tasks.

Is the insert suitable for internal turning as well as external turning?
Yes; the rhombic CCMT geometry and compact dimensions make the insert appropriate for both external and internal turning applications where space and rigidity are considerations.
