DCMT 11T308 AH725 – Indexable turning insert for precision turning (Tungaloy)

The DCMT 11T308 AH725 is an ISO-standard indexable insert designed for external and internal turning operations, optimised for applications across varying materials and stability demands.

• PVD-coated carbide AH725 for process security
• Universal grade for Stahl and rostfreier Stahl
• Rhombic form DCMT with 7° clearance
• Cylindrical hole with single-side countersink

Consistent performance with a universal PVD-coated grade

The PVD-coated carbide AH725 grade is formulated to deliver process security across mixed production runs. As a universal, chip-breakage-resistant grade, it maintains a robust cutting edge when machining both Stahl and rostfreier Stahl, which is particularly valuable where material batches change or where smaller tool geometries demand predictable behaviour. The coating reduces flank wear and supports repeatable cutting conditions, helping to extend tool life and reduce unplanned downtime without sacrificing surface quality.

Geometry and clamping that enhance stability and accuracy

The rhombic geometry with a 55° approach provides versatility for turning and finishing, while the 7° clearance minimises rubbing during the cut. The 0.8 mm corner radius balances edge strength and the capability to produce tight radii finishes; the 3.97 mm plate thickness contributes to rigidity under moderate cutting forces. The ISO 11T308 designation ensures dimensional compatibility with standard toolholders; the cylindrical hole with single-side countersink (40°–60°) enables secure clamping, stable repeatability and straightforward index changes in production settings.

Predictable chip control and improved surface finish

Equipped with a single-sided chipbreaker, this insert supports controlled chip formation across typical feed ranges for medium and finishing cuts. Effective chip control reduces interruptions from long or tangled chips, improves process safety, and helps achieve a finer surface finish with fewer rework cycles. The combination of grade and chipbreaker makes the insert suitable for stable cycles where consistent part quality and reduced machine idle time are priorities.

System compatibility and practical application guidance

The insert is supplied as part of an ISO-based system: indexable insert, compatible external holder or boring bar, appropriate seat/clamping kit and replacement screws for secure mounting. Select the chipbreaker and AH725 grade to match the selected workpiece Stahl or rostfreier Stahl, machining strategy and assembly rigidity. The article is listed under SKU 6864864-Tungaloy and can be referenced when specifying holder interfaces or reordering parts; the combination of geometry, grade and secure clamping supports reliable integration into serial production.
