DCMT DCMT11T308 AH8015 – Indexable Turning Insert for Turning, Tungaloy (PVD-coated carbide, 0.8 mm radius)

The DCMT11T308 AH8015 Tungaloy is an ISO-standard rhombic turning insert designed for general turning of heat-resistant alloys and versatile external and internal turning tasks

• ISO rhombic insert DCMT11T308, 55° cutting angle
• PVD-coated AH8015 grade for heat-resistant alloys
• 0.8 mm corner radius for consistent edge strength
• Cylindrical hole with single-side 40°–60° countersink

Consistent cutting performance on heat-resistant alloys

The PVD-coated AH8015 grade combines a wear-resistant coating with a tough carbide substrate to deliver a balanced performance between abrasion resistance and edge stability. This combination is particularly suited to machining heat-resistant alloys, where elevated cutting temperatures and abrasive wear can shorten tool life. The PVD layer reduces adhesion and built-up edge while the substrate maintains integrity under interrupted cuts, resulting in fewer insert changes and more predictable cycle times. The outcome is a stable cutting process that supports higher productivity without compromising surface quality.

Precise fit and secure clamping for stable machining

The ISO-standard geometry and rhombic shape ensure compatibility with a wide range of external holders, with fit determined by form, clearance angle, tolerance class, fastening method, size and thickness. The DCMT11T308 form with its 55° cutting angle supports versatility between finishing and light roughing, while the cylindrical hole with single-side countersink (40°–60°) enables reliable clamping and repeatable positioning. Selecting a matching holder, backing pad and correct torque for the clamping screw reduces vibration and improves repeatability, which in turn preserves cutting edge life and achieves consistent component tolerances.

Process benefits: productivity, surface quality and predictable life

A 0.8 mm corner radius provides a compromise between edge robustness and achievable surface finish: larger radii support higher feed rates and longer life under heavier cuts, while still allowing fine surface results when machining with appropriate feeds. The one-sided chipbreaker design channels swarf effectively for many turning scenarios, lowering the risk of chip entanglement and enhancing machine uptime. Overall, the insert’s geometry and grade contribute to fewer tool changes, reduced setup variability and a measurable improvement in throughput for batch and series production.

FAQ

What materials is this insert suited for?
The DCMT11T308 AH8015 insert is optimised for heat-resistant alloys and provides a balanced performance between wear resistance and edge stability for those materials.

Does the insert fit standard DCMT holders?
Yes. The DCMT11T308 follows ISO-standard dimensions and requires a holder matched by form, clearance angle and tolerance class for secure clamping.

What is the purpose of the countersunk hole design?
The cylindrical hole with a single-side countersink (40°–60°) ensures reliable clamping and repeatable seating, which improves stability and repeatability during turning.

Can this insert be used for both finishing and roughing?
With its 55° geometry and 0.8 mm corner radius, the insert offers a compromise suitable for light roughing and finishing when process parameters and holder rigidity are appropriate.

How does the AH8015 grade affect tool life?
The PVD-coated AH8015 grade combines wear resistance with edge stability, reducing built-up edge and improving longevity under elevated temperatures typical for heat-resistant alloys.
