CCMT 09T304 AH6235 Tungaloy indexable turning insert — PVD-coated carbide, 0.4 mm corner radius for turning

CCMT 09T304 AH6235 is an ISO-format indexable turning insert designed for general external and internal turning, offering a tough grade optimised for interrupted cuts and materials prone to chipping.

• PVD-coated carbide for extended edge life
• Tough grade for rostfreier Stahl and interrupted cuts
• 0.4 mm corner radius for versatile profile work

High-performance grade for demanding turning tasks

The insert is produced in a PVD-coated carbide grade that balances wear resistance and toughness. This composition yields a stable cutting edge under variable conditions and reduces flank wear during longer cycles. Designed for turning operations, the geometry provides predictable chip formation with a single-sided chipbreaker, which helps maintain consistent surface quality and reduces rework. By selecting a tougher grade, the cutting edge resists sudden fracture in interrupted cuts and applications with increased breakout risk, making it suitable for work on rostfreier Stahl and other alloys where edge stability is critical.

Precise geometry and ISO compatibility for dependable setup

Featuring a 0.4 mm corner radius, an included angle of 80° and a 7° clearance angle, the insert offers a balance between strength and form fidelity. The plate thickness of 3.97 mm increases mounting stiffness and minimises vibration when paired with correctly matched holders. Compatibility with clamping systems is determined by form, clearance angle, tolerance class, fixing method, size and thickness; the ISO designation ensures interchangeability with standard holders. The presence of a cylindrical hole with a single-sided countersink (40°–60°) supports secure fastening and accurate seating, reducing the need for repeated adjustments and enabling faster tool changes on production lines.

Productivity benefits and predictable tool life

Using a dedicated grade such as AH6235 brings tangible production advantages: more consistent chip control, fewer edge failures in unstable cuts and improved overall process reliability. The single-sided chipbreaker is tuned for chip evacuation in typical turning tasks, lowering machine downtime for cleaning and reducing cycle variability. For manufacturers seeking to raise throughput without compromising finish, the insert delivers an economical balance between tool life and cutting performance. When paired with a suitable outer holder or boring bar and correct cutting parameters, it contributes to a smoother, more predictable machining process and reduced scrap rates.

FAQ

What materials is this insert suitable for?
The CCMT 09T304 AH6235 insert from Tungaloy is formulated for applications involving rostfreier Stahl and other steels where a tougher grade reduces chipping in interrupted cuts.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius provides a compromise between edge strength and finished contour accuracy, allowing stable machining with reduced risk of edge breakage while keeping a fine surface profile.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO plate designation conventions and the compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness; use matching ISO holders or appropriate boring bars.

What does the PVD coating deliver in daily use?
The PVD coating increases wear resistance and helps maintain a stable cutting edge, extending useful tool life under varying cutting conditions and improving process reliability.

Can this insert be used for internal and external turning?
The geometry and grade are suitable for both external and internal turning; select a holder and cutting parameters that match the insert’s dimensions and the intended operation.
