CCMT09T308 AH6225 Tungaloy indexable insert for turning — PVD‑coated carbide, 0.8 mm radius

CCMT09T308 AH6225 Tungaloy indexable insert designed for ISO‑standard external and internal turning, offering a sharp yet stable cutting edge for stainless‑steel machining in varied conditions

• PVD‑coated carbide for stainless steels
• 80° rhombic CCMT geometry
• 0.8 mm corner radius for precision finishing
• Cylindrical hole with single‑sided countersink

Consistent cutting performance for stainless steels

The CCMT09T308 AH6225 insert is a PVD‑coated carbide grade developed as a universal choice for stainless steels, optimised to deliver a sharp, stable cutting edge under changing conditions. The AH6225 grade balances wear resistance and toughness, which reduces edge chipping while retaining cutting efficiency during medium cutting depths. For production environments requiring predictable tool life and consistent surface quality, this grade provides measurable improvements in process stability and reduces unexpected downtime.

Fast, reliable clamping and straightforward tool matching

Engineered to the ISO CCMT form, the rhombic plate and cylindrical hole with single‑sided countersink ensure reliable mechanical clamping in compatible holders. Compatibility is governed by plate shape, 7° clearance angle, tolerance class, fastening geometry, size and 3.97 mm plate thickness, so selection of the correct outer holder or boring bar is decisive. The standardised interface helps shorten setup times and secures repeatable position accuracy for serial production and frequent index changes.

Improved surface finish and controlled chip formation

With an 80° approach angle and a 0.8 mm corner radius, the insert supports fine finishing passes while maintaining load distribution across the edge. The integrated single‑sided chipbreaker promotes predictable chip shapes and evacuation, decreasing rework and protecting workpiece finish. In combination, these features deliver a reliable surface quality on both external and internal turning operations and help meet tighter dimensional tolerances with fewer tool interventions.

Practical system design and application guidance

As part of a complete turning system — ISO insert, matching external holder or boring bar, support shim/clamping set and replacement screws — this plate integrates seamlessly into established tool setups. The universal AH6225 grade is suitable for varied cutting strategies: choose the chipbreaker and insert geometry according to workpiece stability and machining depth. For workshop planners and process engineers, the predictable behaviour of this insert simplifies tool inventory decisions and supports efficient production planning.

FAQ

Which materials is this insert best suited for?
The CCMT09T308 AH6225 Tungaloy insert is primarily designed for stainless steels, offering a balanced wear resistance and toughness for medium cutting conditions; it performs well where a sharp but stable edge is required.

Can this plate be used for internal turning and grooving?
Yes — the rhombic CCMT geometry and the single‑sided chipbreaker make the plate suitable for both external and internal turning tasks when paired with an appropriate boring bar or holder.

How does the AH6225 grade influence tool life?
The AH6225 grade, with its PVD coating, provides improved wear resistance under varying cutting conditions, which supports longer tool life and consistent component quality across production batches.

What should be considered when selecting a holder?
Holder compatibility depends on plate form, 7° clearance angle, tolerance class, fastening style, plate size and thickness; using a holder specified for CCMT‑type inserts ensures secure clamping and positional repeatability.

How does the chipbreaker affect machining?
The single‑sided chipbreaker is designed to produce manageable chip shapes and facilitate evacuation, improving surface finish and reducing the risk of rework in turning operations.
