DCMT 11T304 AH8005 Tungaloy turning insert — indexable insert for Turning

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

• PVD-coated carbide grade AH8005
• 0.4 mm corner radius for robust cutting
• Rhomboid 55° geometry for versatile turning
• Cylindrical hole with single-side countersink 40°–60°

Consistent metal removal with a wear-resistant carbide grade

The PVD-coated carbide grade AH8005 provides enhanced resistance to abrasion and thermal loading, which translates into longer tool life and fewer indexings per component. The combination of a thin, hard coating and a substrate engineered for strength ensures reliable performance when machining heat-resistant alloys and other demanding materials. By choosing this grade, shops benefit from reduced tool changes and improved process uptime while maintaining consistent component quality.

Secure clamping and geometry that supports stable turning

As an ISO-standard indexable insert, compatibility with holders is governed by shape, clearance angle, tolerance class, clamping type, size, and thickness. The rhomboid form with a nominal 55° included angle and 7° clearance provides a balanced cutting edge suitable for a range of external and internal turning tasks. The insert’s cylindrical hole with a single-side countersink (40°–60°) enables precise clamping and repeatable positioning in a matching toolholder, reducing vibration and improving surface finish on the workpiece.

Practical benefits for production efficiency and part quality

A 0.4 mm corner radius offers a compromise between edge strength and surface finish: robust enough to withstand interrupted cuts and moderate depth of cut, yet fine enough to achieve acceptable surface quality without additional dressing. The 3.97 mm plate thickness and the one-sided chipbreaker design support controlled chip formation for stable cutting forces. Together, these attributes help to lower cycle times, decrease scrap rates and deliver predictable tool behaviour — factors that contribute directly to cost-effective machining in serial production.

FAQ

What materials can be machined with this insert?
The DCMT11T304 AH8005 insert from Tungaloy is formulated for heat-resistant alloys and hard materials; the AH8005 grade and PVD coating improve wear resistance for these workpiece types.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm radius increases edge strength compared with finer radii, helping to withstand interrupted cuts while still permitting good surface finish when using appropriate cutting parameters.

Which holders are compatible with this ISO insert?
Compatibility depends on matching the rhomboid form, 7° clearance, tolerance class, clamping method, size (11 mm) and thickness (3.97 mm); use a holder or boring bar specified for ISO DCMT-style inserts.

Is the insert reversible or indexable?
The component is an indexable insert designed for indexing; the one-sided chipbreaker and hole/clamping arrangement allow for secure replacement and repeatable positioning.

What fastening method is recommended for stable clamping?
Use a compatible clamping set with the appropriate screw and shim for DCMT geometry; the cylindrical hole and single-side countersink (40°–60°) ensure centring and firm clamping in the correct holder.
