DCMT11T304 AH8005 Tungaloy turning insert — ISO rhombic indexable insert with 7° clearance

DCMT11T304 AH8005 Tungaloy insert is an ISO-standard indexable turning plate designed for stable external and internal turning of heat-resistant alloys and other hard materials

• Rhombic ISO insert DCMT11T304
• PVD-coated carbide AH8005 grade
• 7° clearance angle for stable cutting
• 0.4 mm nose radius for fine profiling

Durable grade for high-temperature and hard-material turning

The AH8005 grade is a PVD-coated carbide developed for wear resistance in the machining of heat-resistant alloys and other hard workpiece materials. In stable setups this grade extends tool life through improved edge stability and reduced flank wear, which translates into fewer insert changes and more consistent production runs. The coating enhances resistance to adhesive and abrasive wear while preserving cutting-edge integrity during higher thermal loads.

Geometry engineered for precision and surface quality

The rhombic plate with a 55° included angle and 0.4 mm nose radius offers a balance between profile definition and cutting robustness. The moderate nose radius supports improved surface finish without compromising edge strength, while the 7° clearance ensures the rake and relief geometry reduce rubbing and heat build-up. The insert’s hole arrangement — a cylindrical bore with a single-sided countersink (40°–60°) — permits secure clamping and repeatable positioning in compatible holders.

System compatibility and reliable fixture integration

Supplied as part of the ISO turning insert system, the plate is compatible with matching external holders or boring bars when the form, clearance angle, tolerance class, clamping method, size and thickness correspond. The system typically comprises the insert, an appropriate outer holder or boring bar, a backing/clamping set and replacement screws. Choosing components from the same ISO family ensures repeatable seating, predictable run-out and consistent cutting conditions across multiple machining stations.

Practical machining benefits and recommended applications

Designed for both external and internal turning, the single-sided chipbreaker and AH8005 composition help control chip flow in continuous cuts and interrupted operations when stability is maintained. The combination of turning-optimised geometry and chipbreaker selection reduces rework and improves batch-to-batch consistency. For best results, pair the insert with a rigid setup and a holder matched to the insert thickness and size to exploit the stable machining characteristics and to secure reliable surface finish and extended tool life.

FAQ

Which materials is this insert suitable for?
The DCMT11T304 AH8005 Tungaloy insert is formulated for machining heat-resistant alloys and other hard materials where a wear-resistant PVD-coated carbide provides sustained performance.

Can this plate be used for internal turning as well as external turning?
Yes, the insert’s rhombic geometry and single-sided chipbreaker make it suitable for both external and internal turning when combined with an appropriate boring bar or holder.

What does the AH8005 designation indicate?
AH8005 denotes a PVD-coated carbide grade optimised for wear resistance and edge stability under elevated temperatures and demanding cutting conditions.

How does the 0.4 mm nose radius affect the machining result?
A 0.4 mm nose radius balances surface finish and edge strength, delivering fine profiling while maintaining robustness against edge chipping in stable setups.

How should compatibility with the holder be checked?
Compatibility is determined by matching insert form, clearance angle, tolerance class, clamping method, size and thickness; using holders from the same ISO family ensures correct seating and repeatability.
