DCMT11T308 AH8005 – Indexable turning insert for ISO turning, PVD-coated carbide, 0.8 mm nose radius, by Tungaloy

The DCMT11T308 AH8005 is an ISO-standard indexable turning insert designed for external and internal turning, optimised for heat-resistant alloys and hard materials with a stable machining setup

• ISO-form DCMT 11T308, rhombic geometry
• PVD-coated carbide AH8005 for wear resistance
• 0.8 mm nose radius for fine profile accuracy
• Compatible with ISO turning holders; cylindrical hole + countersink

High-performance cutting for heat-resistant and hard materials

The combination of a PVD-coated AH8005 grade and a carbide substrate delivers enhanced wear resistance and thermal stability during continuous turning operations. This grade is formulated for machining heat-resistant alloys and other demanding materials where edge durability directly affects productivity. With a rhombic form and a controlled chipbreaker, the insert supports stable chip formation and consistent surface finish, reducing the need for frequent tool changes and therefore improving overall process efficiency. The coating reduces flank wear and extends service intervals under challenging cutting conditions.

Precision fit and reliable clamping reduce rework

Compatibility with the toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness. The insert’s 7° clearance angle and ISO 11T308 geometry ensure a predictable seating in standard external holders, while the cylindrical hole with single-sided countersink (40°–60°) provides secure fixation and repeatable positioning. Correct matching of holder and insert minimises runout and vibration, leading to improved dimensional accuracy and fewer rejected parts. The controlled geometry also supports reliable coolant flow and chip control in many shop-floor setups.

Practical selection and machining recommendations for stable results

The one-sided chipbreaker and a 0.8 mm nose radius make this plate suitable for finishing to medium-light roughing passes where profile accuracy is required. For best results, select a holder and mounting combination that match the insert’s size (11 mm) and thickness (3.97 mm) and adapt cutting parameters to workpiece material and machine rigidity. The ISO-standard design simplifies replacement and inventory management, while the PVD wear layer offers balanced performance across a wide range of cutting speeds. If uncertainty remains about the ideal grade or chipbreaker for a specific job, technical consultation is advised to optimise cycle times and tool life.

FAQ

How does the AH8005 coating improve performance during turning?
The AH8005 PVD coating on the DCMT11T308 increases wear resistance and heat tolerance, which prolongs tool life when turning heat-resistant alloys and high-strength materials.

Which holder characteristics must be matched to this insert?
Compatibility is determined by the insert form, clearance angle (7°), tolerance class, fastening method, size (11 mm) and thickness (3.97 mm); matching these parameters ensures proper seating and repeatable machining performance.

Is the insert suitable for both external and internal turning?
Yes, the ISO 11T308 geometry and rhombic shape make the insert suitable for both external and internal turning tasks when used with a compatible holder.

What role does the one-sided chipbreaker play in cutting results?
The one-sided chipbreaker promotes controlled chip formation and evacuation, improving surface finish and reducing the likelihood of built-up edge during stable cutting conditions.

Can this insert be used on a variety of workpiece materials?
The AH8005 grade is optimised for heat-resistant alloys and hard materials; it also performs well across a range of steels and alloyed materials when cutting parameters are adapted to the workpiece and machine rigidity.
