DCMT 070204 AH120 – Turning indexable insert by Tungaloy, PVD-coated carbide, 55°

DCMT 070204 AH120 is an ISO-designation indexable insert for turning, engineered for process reliability and a sharp cutting edge in demanding machining tasks

• PVD-coated carbide AH120 for wear resistance
• 0.4 mm corner radius for consistent finishes
• Rhombic 07 form with 55° approach angle
• Single-sided chipbreaker, with cylindrical hole

Reliable chip control and extended edge life

The insert’s PVD coating combined with the AH120 grade delivers a balance of wear resistance and toughness that stabilises the cutting edge. The single-sided chipbreaker is designed to guide chips predictably during turning operations, reducing the risk of vibration and edge chipping. For production environments this means fewer unexpected interruptions and more consistent component quality; the coating also helps to maintain cutting performance over longer tool life, which supports higher uptime and productive machining.

ISO compatibility and secure clamping for quick changeovers

Built to the ISO-series specification, the insert’s rhombic 07 geometry and the presence of a cylindrical hole with one-sided countersink (40°–60°) ensure secure seating in standard holders. Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; the 2.38 mm plate thickness and the 7° clearance angle are important for correct seating and repeatability. Using ISO-standard inserts simplifies inventory management and reduces setup time during insert changes, which is particularly advantageous in mixed-production or batch environments.

Predictable surface quality and versatile turning performance

The 0.4 mm corner radius and the 55° insert angle support a balance between strength and finish: a modest corner radius helps attain good surface texture while maintaining a reliable edge for finishing cuts. This design is suitable for both external and internal turning when the correct chipbreaker and cutting data are selected. For best results, pair the insert with a stable holder and appropriate feed and speed settings to exploit the grade’s process security and to achieve reproducible surface quality across repeated runs.

FAQ

Is the DCMT 070204 AH120 suitable for finishing or roughing operations?
The DCMT 070204 AH120 insert from Tungaloy is optimised for process security and a sharp cutting edge; it can be used for light finishing and stable medium cutting operations when the feed, speed and holder rigidity are matched to the task.

Which holders are compatible with this ISO insert?
Compatibility follows ISO standards: the insert’s form, 7° clearance, tolerance class, fastening method, 07 size and 2.38 mm thickness determine whether a specific external holder or boring bar accepts the DCMT 070204 AH120.

How does the 0.4 mm corner radius affect machining results?
A 0.4 mm corner radius improves edge strength while still permitting a fine surface finish; it is a compromise between robustness and the ability to achieve consistent surface quality in typical turning applications.

What does the AH120 grade provide in practice?
The AH120 PVD-coated carbide grade offers a combination of wear resistance and resistance to edge chipping, delivering stable performance during continuous turning operations under moderate cutting conditions.

Can the insert be used for internal turning?
Yes, the DCMT 070204 AH120 is suitable for internal turning when used with an appropriately sized and rigid boring bar that accommodates the rhombic 07 geometry and the insert’s thickness.
