DCMT 11T312 AH6235 – ISO turning insert for external and internal turning, Tungaloy

A precise DCMT11T312 AH6235 ISO turning insert engineered for demanding rostfreier Stahl work and interrupted cuts, supplied as a rhombic indexable insert for standard ISO holders.

• PVD-coated carbide grade AH6235
• Optimised for rostfreier Stahl and interrupted cuts
• Rhombic insert with 1.2 mm corner radius

Durable cutting performance for high-risk interruptions

The PVD-coated carbide grade AH6235 provides a tougher substrate and a coating that improves edge security under cyclic loading and interrupted cuts. This combination results in stable chip formation and reduced flank wear during heavy engagement, which translates into fewer regrinds and longer tool life. The tougher grade is particularly suitable for applications with elevated breakout risk, improving process reliability in series production.

Consistent fit within ISO tooling systems

Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; the insert follows the ISO designation DCMT11T312, ensuring interchangeability with matching holders and boring bars. The rhombic shape and the specified dimensions allow straightforward replacement and re-indexing, reducing spindle downtime. A clear system setup — insert, holder, shim/clamping kit and replacement screws — supports consistent assembly and repeatable results.

Geometry that balances edge strength and precision

The 1.2 mm corner radius and a 7° relief angle are chosen to balance cutting-edge toughness and dimensional control. The moderate corner radius increases resistance to chipping while maintaining acceptable roughness for finishing passes, so fewer follow-up operations are required. The insert thickness of 3.97 mm and the rhombic form contribute to mechanical stability during heavy cuts and interrupted sequences.

Practical features for secure clamping and process control

A cylindrical hole with single-sided countersink (40°–60°) enables secure fastening and precise location in standard clamping systems. The one-sided chipbreaker design helps direct chips away from the cutting zone, improving surface quality and evacuation, especially with rostfreier Stahl. By selecting the right chipbreaker and grade for the material and machining conditions, users can increase productivity and reduce scrap rates.

FAQ

What materials is this insert best suited for?
The DCMT11T312 AH6235 Tungaloy insert is formulated for machining rostfreier Stahl and other demanding materials where interrupted cuts and breakout risk occur, thanks to the tougher PVD-coated grade.

How does the 1.2 mm corner radius affect machining results?
A 1.2 mm radius increases edge strength and resistance to chipping, improving tool life in interrupted cutting and providing a balance between surface finish and robustness.

Is this insert compatible with standard ISO holders?
Yes, the insert follows the ISO designation DCMT11T312 and is compatible with holders and boring bars designed for that form, provided the holder matches form, relief angle, tolerance class, fastening type, size and thickness.

What does the hole design contribute to the setup?
The cylindrical hole with a single-sided countersink (40°–60°) enables secure clamping and precise positioning in standard clamping assemblies, reducing the risk of insert movement during heavy cuts.

Why choose the AH6235 grade for production?
AH6235 is a tougher, PVD-coated carbide grade that offers improved edge security and stable chip formation in rostfreier Stahl, making it suitable for applications with increased breakout risk and interrupted cuts.
