DCMT 11T302 AH725 Tungaloy indexable insert for turning

The DCMT11T302 AH725 is an ISO rhombic indexable insert designed for external and internal turning, offering a universal, fracture-resistant grade for steel and stainless steels.

• PVD-coated carbide grade AH725
• Rhombic ISO insert, size 11
• 0.2 mm corner radius for fine turning
• Cylindrical hole with 40°–60° countersink

Stable cutting across mixed steels for reliable throughput

The PVD-coated AH725 grade is formulated as a universal, fracture‑resistant carbide solution, making it suitable for both standard steel and stainless steels where machining conditions vary. The combination of the coating and substrate provides improved edge strength and consistent wear behaviour, which directly supports higher process reliability and reduces unexpected interruptions during batch runs. In practice, this means fewer unplanned insert changes and steadier cycle times on medium‑duty turning tasks.

Geometry that improves surface finish and dimensional control

The rhombic ISO geometry and size 11 format, together with a 0.2 mm corner radius and 7° clearance, create a cutting profile that balances strength with the ability to produce fine finishes. The 3.97 mm thickness contributes to rigidity and heat resistance in the cutting zone, helping to preserve the cutting edge under moderate interruptions or variable feeds. For operations requiring consistent part tolerance and reduced secondary finishing, these geometric choices translate into measurable benefits in first‑pass quality.

Secure seating and predictable chip behaviour minimise downtime

A cylindrical hole with a 40°–60° countersink and a single‑sided chipbreaker provide reliable mechanical clamping and acceptable chip control for many turning tasks. Correct holder compatibility—determined by insert form, clearance, tolerance class, fastening method, size and thickness—ensures a secure fit and repeatable positioning. This predictable assembly reduces the risk of seating errors, shortens changeover time and supports safer, more efficient tool handling on the shop floor.

Practical system advantages for everyday production

As part of a complete turning system—insert, suitable outer holder or boring bar, shim/clamp set and spare screws—the insert supports straightforward inventory management and fast replacement. The universal nature of the grade makes the component versatile for smaller tools and jobs with high demands on process stability, delivering a durable cutting edge and tangible savings through reduced reworks. Where process reliability and consistent throughput are priorities, the insert promotes production stability in both external and internal turning applications.

FAQ

Is this insert suitable for stainless steels? The AH725 grade is a universal, fracture‑resistant carbide developed for machining both steel and stainless steels, so the insert performs well when switching between these materials.

What holders are compatible with this insert? Compatibility depends on insert form, clearance, tolerance class, fastening method, size and thickness; the DCMT11T302 fits holders designed for rhombic ISO 11T302 inserts with matching clamping geometry.

How does the 0.2 mm corner radius affect machining? A 0.2 mm corner radius reduces cutting forces and helps achieve finer surface finishes, making the insert suited to finishing passes and jobs requiring tight dimensional control.

What chip control can be expected with this insert? The single‑sided chipbreaker offers controlled chip formation in many turning operations; pairing the insert with an appropriate feed and holder enhances chip evacuation.

Can the insert be used for both external and internal turning? Yes, the insert is specified for both external and internal turning when mounted in suitable holders or boring bars that align with its ISO geometry and clamping requirements.
