CNMG 090404 AH6225 turning insert by Tungaloy — PVD-coated carbide, rhombic 80° shape

CNMG 090404 AH6225 is an ISO‑standard turning insert designed for general-purpose external and internal turning where a sharp, yet robust cutting edge is required

• ISO CNMG 090404 format
• PVD-coated carbide AH6225 for rostfreier Stahl
• Rhombic 80° geometry with cylindrical hole
• Double-sided chipbreaker for cost efficiency

High-process reliability with an optimised cutting grade

The insert combines a PVD-coated carbide substrate with the AH6225 grade, engineered as a universal solution for machining rostfreier Stahl under varying conditions. The coating improves wear resistance while the substrate maintains edge stability during medium cutting depths; this results in fewer interruptions and more predictable tool life. As part of an ISO series, the geometry is standardised so selection is based on holder compatibility and intended operation rather than bespoke tooling, which simplifies procurement and planning in production environments.

Designed for secure clamping and repeatable indexability

The rhombic CNMG form with a cylindrical hole and a plate thickness of 4.76 mm ensures reliable seating in compatible external holders or boring bars. The insert is double-sided, providing two usable cutting edges per index, which lowers cost per edge and reduces downtime for edge changes. Compatibility is determined by form, 0° relief angle, tolerance class, fastening and plate size; matching these parameters guarantees correct contact, repeatable clamping force and consistent cutting geometry across tool changes.

Practical productivity advantages on the shop floor

Using a universal grade such as AH6225 delivers a balance between edge sharpness and toughness, suitable for fluctuating cutting conditions common in batch and job shop work. The 0.4 mm corner radius supports a stable chipping behaviour while maintaining surface finish, and the 80° rhombic angle provides good access for external profiling tasks. The PVD coating helps control built-up edge and extend the effective life of the cutting edge, contributing to predictable maintenance intervals and improved overall productivity.

Selection guidance and recommended setup

Choose the chipbreaker and grade to match the workpiece material, machining type and fixture stability; the included double‑sided chipbreaker is a versatile starting point for general turning. Ensure the clamping set, underlay or screw meets the ISO form and tolerance requirements so that the insert seats without play. For less rigid set-ups or heavy interrupted cuts, select a more robust holder and verify that the insert orientation matches the required lead and clearance angles; correct matching reduces chatter, improves surface integrity and prolongs insert life.

FAQ

What materials is this insert suitable for?
The CNMG 090404 AH6225 turning insert is specified as a universal grade optimised for rostfreier Stahl and is primarily recommended for machining stainless-type steels under medium cutting conditions.

Is the insert indexable and how many cutting edges are available?
This indexable CNMG insert is double-sided, providing two usable cutting edges; each edge is identical when indexed and clamped correctly.

Which dimensions and geometry should be matched in the holder?
Holder compatibility depends on form, relief angle (0°), tolerance class, fastening method, size (09) and plate thickness (4.76 mm); matching these parameters ensures correct seating and secure clamping.

What advantages does the PVD coating provide?
The PVD coating on the AH6225 grade increases wear resistance and helps control built‑up edge during turning, supporting longer edge life and more consistent surface quality.

What are the identification details for ordering?
Order using Article number 6903159 or SKU 6903159-Tungaloy; the manufacturer SKU is TUN6903159 and the model is CNMG 090404 AH6225.
