DCMT DCMT11T304 AH6235 turning insert — Tungaloy (ISO rhombic, 0.4 mm radius)

DCMT11T304 AH6235 is an ISO-standard rhombic turning insert designed for external and internal turning, optimised for rostfreier Stahl and interrupted cuts

• PVD-coated AH6235 carbide grade
• Optimised for rostfreier Stahl applications
• 0.4 mm corner radius for versatile turning
• ISO rhombic form with cylindrical hole and countersink

Durable grade for demanding rostfreier Stahl operations

The PVD-coated AH6235 grade is formulated for tougher applications and is particularly suited to rostfreier Stahl and interrupted cutting conditions. This indexable insert delivers improved resistance to edge breakup and consistent cutting performance where material adhesion and built-up edge are common challenges. By selecting this tougher grade, process stability is increased and unexpected tool failures are reduced, which supports more predictable machining cycles and better surface integrity on the workpiece.

Geometry and holder compatibility for secure clamping

The rhombic ISO form with a 55° cutting angle and 7° clearance ensures a balanced contact geometry for many standard turning holders. The insert features a 0.4 mm corner radius and a plate thickness of 3.97 mm, with a cylindrical hole plus single-side countersink (40°–60°) for positive seating. Compatibility with a holder depends on form, clearance angle, tolerance class, clamping method, size and thickness; matching the insert to a suitable external holder or boring bar preserves the cutting edge and reduces vibration in less rigid set-ups.

Practical benefits for productivity and process security

Selecting the correct chipbreaker and the AH6235 grade supports stable chip formation and decreases the risk of catastrophic edge failure in unstable cutting scenarios. The combination of PVD coating and tough carbide substrate helps maintain a productive cutting edge under variable cutting parameters, offering longer tool life and lower tool-change frequency. These performance attributes translate into higher machine uptime and improved economic efficiency for component batches that include rostfreier Stahl or interrupted features.

System considerations and recommended workflow

The system comprises the ISO insert together with a matched external holder or boring bar, a shim/clamp set and replacement screws where required. For best results, choose the chipbreaker variant according to workpiece material, machining strategy and machine rigidity; light finishing passes benefit from smaller corner radii, while roughing requires more robust edge preparation. Ensure holders are within ISO tolerance classes and use appropriate clamping torque to avoid slippage and ensure repeatable positioning of the insert.

FAQ

What materials is this insert best suited for?
The DCMT11T304 AH6235 insert from Tungaloy is optimised for rostfreier Stahl and other challenging alloys where toughness and resistance to edge breakout are required.

Can this insert be used for both external and internal turning?
Yes, the ISO rhombic form and geometry make this indexable insert suitable for both external and internal turning operations when paired with an appropriate holder.

What does the AH6235 grade offer compared with standard grades?
AH6235 is a tougher PVD-coated carbide grade designed for increased resistance to chipping and improved performance in interrupted cuts, providing longer effective edge life in difficult rostfreier Stahl applications.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the DCMT11T304 designation requires a holder that accepts ISO rhombic inserts of size 11 with the corresponding thickness and hole style.

Is a specific chipbreaker recommended for roughing or finishing?
Choose the chipbreaker variant to match the machining task: more aggressive breakers for roughing and stable chip evacuation, finer geometries for finishing passes to improve surface quality and dimensional control.
