DCMT11T304 AH8005 Tungaloy turning insert — PVD‑coated carbide, rhombic 55° geometry

The DCMT11T304 AH8005 is a rhombic, ISO‑standard indexable insert designed for external and internal turning of heat‑resistant alloys and hard materials, providing a wear‑resistant solution for stable machining operations.

• PVD-coated AH8005 grade for high wear resistance
• Rhombic DCMT shape, 55° cutting angle
• 0.4 mm corner radius for reliable edge strength
• Compatible with ISO turning toolholders, with hole

Consistent wear resistance for demanding materials

The PVD‑coated AH8005 grade combines a wear‑resistant coating with a tough carbide substrate to extend tool life in challenging conditions. This composition is especially suited to machining heat‑resistant alloys, where temperature and abrasion can rapidly degrade uncoated edges; the coating reduces flank wear and preserves the cutting edge, leading to fewer insert changes and more consistent component tolerances. The result is improved process reliability without sacrificing performance.

Precise geometry for stable, repeatable turning

With a 55° cutting angle and 0.4 mm corner radius, the insert delivers a balance between chip control and edge strength that benefits both finishing and light semi‑finishing passes. The 7° clearance reduces rubbing while maintaining support behind the cutting edge, decreasing vibration and ensuring consistent surface finish. These geometric choices translate to predictable cutting forces and help to maintain tool life under stable machining conditions.

Easy integration into ISO tool systems

The insert is an ISO‑standard rhombic form with a cylindrical hole with single‑sided countersink (40°–60°), enabling secure clamping in a wide range of holders and boring bars. The 3.97 mm thickness and size 11 footprint ensure compatibility with common external and internal turning toolholders, simplifying tool selection in mixed‑tool environments. Clear identification and standardised dimensions reduce setup time and help maintain reproducible clamping repeatability.

Targeted chip control and application focus

Engineered with a one‑sided chipbreaker, the DCMT11T304 is optimised for steady chip formation in applications where stability and surface integrity matter most. The chipbreaker and grade pairing promotes predictable swarf evacuation when cutting tougher materials, lowering the risk of built‑up edge and improving workpiece finish. For shops working with alloys requiring robust edges, this combination supports productive, repeatable machining cycles.

FAQ

What materials is this insert suitable for?
The DCMT11T304 AH8005 insert is designed for heat‑resistant alloys and hard materials, using the AH8005 grade and PVD coating to improve wear resistance in such applications.

Which insert geometry and angles does it feature?
This rhombic insert has a 55° cutting angle, 7° clearance and a 0.4 mm corner radius, providing a compromise between edge strength and chip control for stable turning.

How is the insert mounted in a toolholder?
Mounting uses the ISO‑standard cylindrical hole with a single‑sided countersink (40°–60°); the form and tolerance class determine compatibility with corresponding ISO turning holders.

What benefits does the AH8005 coating bring?
The PVD‑coated AH8005 grade enhances wear resistance and thermal stability, which reduces flank wear and contributes to longer insert life in abrasive or high‑temperature cutting conditions.

Is this insert suited for internal as well as external turning?
Yes, the insert’s form and size make it suitable for both external and internal turning when paired with an appropriate ISO‑compatible holder or boring bar.
