CPMT080204 AH6235 indexable turning insert, PVD‑coated carbide, for stainless steel — Tungaloy

The CPMT080204 AH6235 is an ISO‑standard indexable insert developed for external and internal turning, offering a rhombic form with an 80° included angle and a grade tuned to interrupted cuts and high chipping risk.

• ISO‑standard rhombic insert, 80° included angle
• PVD‑coated carbide grade AH6235 for stainless steel
• Cylindrical hole with single‑side countersink
• One‑sided chipbreaker for controlled chips

Predictable mounting and system compatibility for efficient production

The ISO‑format design ensures that the insert is compatible with a wide range of external holders and boring bars when matched by form, relief angle, tolerance class, clamping and nominal size. This standardisation reduces setup time and supports repeatable seating and clamping; as a result, tool changeovers are simplified and process stability is improved. The insert’s secure fastening is supported by a cylindrical hole with single‑side countersink (40°–60°), which helps to centre the component reliably and maintain cutting geometry under load.

Tough, PVD‑coated carbide grade for difficult stainless‑steel operations

The carbide grade AH6235, supplied as a PVD‑coated grade, is formulated for tougher behaviour and enhanced edge security when machining stainless steel or when processing with interrupted cuts. The PVD layer increases wear resistance and maintains a sharper flank for longer, which leads to fewer edge failures and a more consistent surface finish. For customers seeking higher process reliability in challenging materials, this combination of substrate and coating provides a balance between resistance to built‑up edge and sufficient toughness to resist chipping.

Geometry tailored to versatility in turning and simple handling

The insert’s rhombic shape with an 80° included angle, a 0.4 mm corner radius and an 11° clearance angle gives a versatile contact geometry that supports both roughing and finishing passes depending on the chosen holder and cutting parameters. The plate thickness of 2.38 mm contributes to stiffness at the cutting edge while keeping indexable rotations straightforward. The single‑sided chipbreaker is designed to control chip form in many turning setups, lowering the risk of entanglement and facilitating safer, cleaner machining. Replacement is part of a system: the insert works within a set‑up comprising holder, shim and clamping screw specified to the ISO family.

FAQ

What holders are compatible with this insert?
Compatibility is determined by ISO form, clearance angle, tolerance class, clamping method, nominal size and plate thickness; the CPMT080204 AH6235 insert fits ISO‑compliant external holders and boring bars when these parameters match.

Is this grade suitable for continuous stainless‑steel turning?
The AH6235 grade is formulated for tougher performance and is especially effective where chipping risk or interrupted cuts occur; in continuous stainless‑steel operations it provides improved edge stability and wear resistance.

What does the hole style mean for mounting?
The cylindrical hole with a single‑side countersink (40°–60°) enables reliable centring and secure clamping, reducing play and supporting consistent cutting geometry under load.

Which machining tasks benefit most from the 0.4 mm corner radius?
A 0.4 mm corner radius balances strength and finish: it increases edge robustness for roughing while still permitting acceptable surface integrity for semi‑finishing passes on challenging materials.

Can the insert be indexed for multiple edges and what is the SKU for ordering?
Yes, the insert is indexable by rotating to unused cutting edges; order reference for the CPMT080204 AH6235 Tungaloy indexable insert is SKU 6903458‑Tungaloy (manufacturer article number 6903458).
