DCMT11T304 AH120 indexable turning insert by Tungaloy — PVD-coated carbide, 7° clearance

The DCMT11T304 AH120 is an ISO‑standard rhombic turning insert intended for external and internal turning, delivering process security where a sharp cutting edge and consistent wear resistance are required.

• PVD-coated carbide grade AH120
• Rhombic 55° insert geometry
• One-sided chipbreaker for stable chips
• Cylindrical hole with 40°–60° countersink

Consistent process security and extended tool life

The insert combines a PVD-coated surface with the AH120 carbide grade to provide high wear resistance and resistance to chipping during interrupted cuts. This composition supports process reliability, reducing the frequency of tool changes and helping maintain consistent part quality. The engineered coating lowers flank wear under typical turning conditions, so users can expect predictable performance and longer intervals between regrinds or replacements.

Easy integration into ISO tool systems for fast changeovers

Designed as an ISO-standard indexable insert, the rhombic 55° geometry and 7° clearance make the plate compatible with a wide range of external holders or boring bars when form, clearance angle, tolerance class, fastening method, size and thickness match. The cylindrical hole with single-sided countersink (40°–60°) ensures secure clamping and straightforward fitment into standard clamping sets and replacement screw assemblies. With a plate thickness of 3.97 mm, integration into existing tool systems is simple, supporting quick tool changes and reduced setup time.

Optimised cutting performance and predictable chip control

A one-sided chipbreaker tailored to the insert profile promotes stable chip formation and evacuation, particularly when machining with appropriate feed and depth of cut settings. The 0.4 mm corner radius supports a balance between edge strength and surface finish, allowing both finishing and light roughing passes depending on the chosen cutting data. For best results, select a chipbreaker and grade matching the workpiece material, machining strategy and machine-tool stability to exploit the insert’s sharp edge and abrasion resistance.

FAQ

What turning tasks suit this insert best? This indexable insert is designed for ISO‑standard external and internal turning where a sharp cutting edge and process reliability are required; the AH120 grade offers wear resistance and chipping protection for a range of turning operations.

How does the AH120 coating improve performance? The PVD-coated AH120 on the DCMT11T304 helps reduce abrasive flank wear and enhances edge stability, which contributes to more consistent component quality and extended tool life.

Which holder types are compatible with this insert? Compatibility depends on holder form, tolerance class, fastening and size; the DCMT11T304 fits ISO rhombic holders and boring bars designed for 55° geometry and a cylindrical hole with countersink, provided the thickness and clamping system match.

What does the 0.4 mm corner radius influence? A 0.4 mm corner radius increases edge strength compared with smaller radii, improving finish on medium‑duty passes while still permitting acceptable surface quality for finishing applications.

Is the insert suitable for interrupted cuts or unstable setups? The AH120 grade is described as wear‑ and chipping‑resistant, making the DCMT11T304 appropriate for conditions where a robust cutting edge is needed; however, matching the chipbreaker and cutting data to machine stability is recommended.
