DCMT 070204 AH6235 turning insert for turning by Tungaloy — PVD-coated carbide, 7° clearance

DCMT070204 AH6235 is an ISO rhombic turning insert designed for external and internal turning, optimised for interrupted cuts and materials with a tendency to work-harden

• PVD-coated carbide AH6235
• Optimised for rostfreier Stahl
• 7° clearance angle for stable cutting
• 0.4 mm nose radius for accurate profiles
• Rhombic ISO insert with central hole

High-performance grade for demanding rostfreier Stahl applications

The PVD-coated cutting grade AH6235 is formulated as a tougher option for operations with elevated breakout risk, such as interrupted cuts and machining of rostfreier Stahl. This tougher microstructure increases resistance to chipping and extends effective edge life under unstable cutting conditions. The combination of the hard PVD layer and a wear-resistant substrate helps maintain dimensional accuracy over longer tool life, reducing tool-change frequency and contributing to predictable production cycles. The result is improved process security and reduced per-part tool costs while retaining consistent performance in demanding turning tasks.

Precise geometry that supports surface finish and repeatability

A modest 0.4 mm nose radius and a 7° clearance angle provide a balance between profile control and cutting stability. The rhombic form and the insert’s 55° included angle deliver accessible cutting edges for both external and internal turning, while the single-sided chipbreaker controls chip flow for common turning feeds. These geometric choices deliver a reproducible contact geometry that supports consistent surface quality and predictable tool behaviour. The small nose radius enables accurate profiling and fine tolerances, whereas the clearance geometry helps avoid rubbing and excessive flank wear during through-cut and finishing passes.

ISO-conform compatibility and system-based efficiency

As an ISO-standard insert, compatibility with a suitable holder depends on form, clearance angle, tolerance class, fastening, size and thickness. The system typically comprises the insert, a matching external holder or boring bar, a shim/seat and securing screws. The insert’s central hole with a cylindrical bore and single-side countersink (40°–60°) ensures secure clamping and straightforward index changes. Using standardised components simplifies inventory management and speeds up regrinding or replacement procedures. When selected to match machine rigidity and workpiece conditions, this insert contributes to shortened set-up times and consistent throughput in series production.

FAQ

What materials is this insert intended for?
The DCMT070204 AH6235 insert is intended primarily for rostfreier Stahl and other materials where a tougher grade is required; the AH6235 coating/substrate combination is chosen for interrupted cuts and applications with increased breakout risk.

How does the 0.4 mm nose radius affect finishing?
A 0.4 mm nose radius provides accurate profile reproduction and supports fine surface finishes while maintaining edge strength for short interrupted cuts.

Which holder characteristics determine compatibility?
Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters with the holder ensures secure clamping and correct cutting geometry.

What type of chip control does this insert use?
This insert uses a single-sided chipbreaker that, combined with the rhombic geometry, promotes controlled chip flow for standard turning feeds and helps maintain stable cutting conditions.

Is the insert suitable for internal turning?
Yes, the ISO rhombic form and the included angle support both external and internal turning operations when paired with an appropriate boring bar or holder.
