CPMT 09T304 AH6225 turning insert — Tungaloy

CPMT 09T304 AH6225 is an ISO-format rhombic turning insert designed for external and internal turning of stainless steels, offering a stable cutting edge and a single-sided chipbreaker for medium cutting conditions.

• PVD-coated carbide for stable cutting
• Universal AH6225 grade for stainless steels
• Rhombic ISO insert with 11° clearance
• 0.4 mm corner radius for precise contours

Reliable performance for stainless steel turning

The CPMT09T304 AH6225 insert is optimised as a universal solution for machining stainless steels, combining a PVD-coated surface with a wear-resistant carbide substrate. The coating reduces built-up edge and improves heat resistance under varying cutting conditions, while the substrate maintains a stable cutting edge during medium-depth cuts. This configuration supports consistent surface quality and repeatable component dimensions, making the insert suitable for shops aiming to balance productivity with predictable tool life.

Compatibility and secure clamping for simple tool integration

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening method, size and thickness; the insert features a cylindrical hole with a one-sided countersink and is supplied in the ISO CPMT format to match common clamping systems. The 11° clearance angle and the standardised plate geometry ensure that the component can be mounted with correct rake and clearance relationships, and the defined 3.97 mm thickness provides sufficient support in the pocket. These dimensions permit secure fastening and reduce the risk of chatter when the assembly is set up according to holder specifications.

Geometry and coatings that increase process reliability

The rhombic plate shape and a 0.4 mm radius deliver a compromise between edge strength and contour fidelity, allowing controlled chip flow with the single-sided chipbreaker for many turning operations. The AH6225 grade is tailored to provide a sharp yet robust edge for medium machining of stainless steels, supporting steady material removal rates under fluctuating conditions. Because the insert is ISO-standardised, replacement and inventory management are simplified, and consistent cutting performance can be expected when the insert is paired with suitable holders and cutting parameters.

FAQ

What materials is this insert designed for? The insert is formulated for machining stainless steels; the AH6225 grade and PVD-coated carbide combination is optimised for medium cutting of corrosion-resistant alloys.

Is the CPMT09T304 suitable for both external and internal turning? Yes; the ISO-format geometry and the single-sided chipbreaker allow use in both external and internal turning operations when the correct holder and setup are used.

What is the corner radius and how does it affect machining? The corner radius is 0.4 mm; this radius balances edge strength and contour accuracy, enabling precise profiles while maintaining a robust cutting edge.

How is compatibility with toolholders ensured? Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the CPMT09T304 follows ISO dimensions to match common holders and fastening systems.

What are the hole and countersink specifications? The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°), allowing standard screw clamping and positional indexing.
