DCMT 11T304 AH725 indexable turning insert – PVD-coated carbide, 0.4 mm radius (Tungaloy)

DCMT 11T304 AH725 is an ISO rhombic indexable turning insert developed for external and internal turning, optimised for stable chip formation and secure engagement in standard turning holders

• DCMT 11T304 ISO insert for standard turning holders
• AH725 PVD-coated carbide for steel and stainless steel
• 7° clearance, 0.4 mm radius, 55° rhombic geometry

Secure chip control for steady process performance

The PVD-coated AH725 carbide grade provides a balance of toughness and wear resistance, making it suited to mixed production where varying steels and stainless steel occur. The combination of a dedicated chipbreaker and the insert’s geometry delivers controlled chip flow, reducing the risk of built-up edge and unexpected tool wear. For users aiming to increase uptime, this leads to fewer interruptions and a more predictable tool life, supporting higher process reliability without complex parameter tuning.

Geometry engineered for accuracy and surface quality

A 55° rhombic form paired with a 0.4 mm nose radius and a 7° clearance angle produces reproducible cutting engagement and consistent surface results. The relatively small nose radius enables fine profile work and close tolerances on turned diameters, while the relief angle helps maintain clearance at the flank to avoid rubbing. These geometric choices translate into measurable benefits on finish and dimensional control, especially where repeatability across batches is required.

Practical system compatibility and straightforward integration

As an ISO-specified insert, the DCMT 11T304 fits a wide range of standard holders and boring bars; compatibility depends on form, clearance, tolerance class, fixation and thickness. The insert’s with-hole design and the supplied countersink specification (cylindrical hole with a single-side countersink at 40°–60°) allow secure clamping and straightforward rotation indexing. The 3.97 mm plate thickness offers mechanical stability in moderate-to-demanding turning tasks while preserving efficient chipbreaking behaviour.

Tailored grade for varied turning tasks

The AH725 grade is engineered as a universal, breakage-resistant option for steel and stainless steel applications. Its PVD-coated carbide construction supports versatile cutting parameters and is particularly useful with smaller tools or where process security is prioritised. For shops aiming to standardise on a single insert family across mixed batches, this grade reduces tool inventory complexity while maintaining performance across different steels.

FAQ

What materials is this insert suitable for? The insert is delivered in AH725 grade and is suitable for machining steel and stainless steel in turning applications.

Can the DCMT 11T304 be used for internal turning as well as external turning? Yes, the ISO rhombic shape and the specified dimensions of the DCMT 11T304 make it suitable for both external and internal turning operations when paired with the appropriate holder.

How does the AH725 grade behave under mixed-material batches? AH725’s PVD-coated carbide balance offers good fracture resistance and wear performance across varying steels, supporting stable process security in mixed-production environments.

What are the key dimensions to check for holder compatibility? Check the ISO designation (DCMT11T304), plate size (11), thickness (3.97 mm), hole style and the rhombic geometry to ensure correct clamping and fit with the chosen holder.

Is the nose radius suitable for finishing operations? The 0.4 mm nose radius supports finer finishes and tighter tolerances, making it applicable for many finishing and semi-finishing turning tasks.
