DCMT 11T312 AH725 — ISO turning insert for Turning, Tungaloy

The DCMT11T312 AH725 is an ISO-indexed turning insert designed for external and internal turning, offering a universal, fracture-resistant grade suited to machining Stahl and rostfreier Stahl.

• ISO insert DCMT 11T312 AH725
• PVD-coated carbide, universal for Stahl
• Single-sided chipbreaker, with centre hole
• 1.2 mm nose radius, 7° relief angle

High-performance cutting for mixed steels and rostfreier Stahl

The combination of a PVD-coated carbide substrate and the AH725 grade provides a balanced performance profile: wear resistance for longer tool life and toughness to resist chipping under interrupted cuts. This results in improved process security and predictable tool-change intervals in batch and serial production. For operations that alternate between different steel types, the insert maintains dimensional stability and reduces scrap through consistent cutting behaviour.

Stable machining and simple clamping for reliable results

With a single-sided chipbreaker and a 1.2 mm nose radius, the geometry promotes controlled chip formation and repeatable surface quality on shafts and bores. The insert’s 7° relief angle and rhombic shape support secure seating in standard ISO holders, while the centre hole with a cylindrical bore and one-sided countersink (40°–60°) enables positive clamping and rapid replacement. The design focuses on making setup and tool changes efficient, thereby reducing non-productive time and improving overall throughput.

Clear compatibility and practical workshop integration

The insert is part of an ISO-based system: proper matching to a holder depends on form, tolerance class, relief angle, fastening and thickness. Typical setups comprise an ISO turning insert, a compatible external holder or boring bar, and the appropriate clamp set and replacement screws. The rhombic geometry and the specified dimensions simplify selection for common turning tasks; material guidance identifies suitability for Stahl and rostfreier Stahl, helping to choose cutting parameters and coolant strategies that favour tool life and surface finish.
