DCMT11T302 AH725 ISO turning insert — Tungaloy, versatile 55° rhombic geometry

DCMT11T302 AH725 is an ISO‑standard indexable insert designed for external and internal turning, delivering reliable chip control and consistent edge life.

• ISO rhombic insert 55° geometry
• PVD‑coated AH725 carbide grade
• Universal, break‑resistant for Stahl and rostfreier Stahl
• Central hole with cylindrical seat, 40°–60° countersink

Maximise uptime with a robust, universal grade

The insert is produced in a PVD‑coated carbide grade (AH725) that combines wear resistance with controlled fracture behaviour, making it particularly suitable where material grades vary. By choosing this grade, machining operations benefit from fewer unexpected insert failures and more predictable tool life, which contributes directly to a stable production flow and lower process interruptions. The single‑sided chipbreaker provides consistent chip formation for common turning tasks.

Achieve reliable machining across steel grades

The geometrical design and material pairing emphasise process security: the rhombic shape with a 55° approach angle and the modest 0.2‑mm corner radius support a balance between cutting edge strength and surface finish. This configuration is advantageous for small‑tool applications and for jobs where frequent workpiece material changes occur. Operators will observe repeatable cutting behaviour when machining both Stahl and rostfreier Stahl, improving batch consistency and reducing scrap rates.

Easy integration with ISO tool systems

Compliance with ISO dimensions simplifies replacement and tool inventory management. Compatibility depends on form, relief angle (7°), tolerance class, clamp method and plate thickness; the insert measures size 11 with a plate thickness of 3.97 mm, and it is supplied with a central hole featuring a cylindrical seat and a single‑side countersink (40°–60°). These details make it straightforward to match the insert to the correct external holder or boring bar, plus the customary shims, clamping set and replacement screws that form a complete turning system.

Practical application guidance for everyday turning

Intended primarily for external and internal turning operations, this indexable insert performs well in finishing and medium roughing passes when combined with suitable cutting parameters and stable clamping. The universal nature of the AH725 grade reduces the need for multiple specialised inserts, which simplifies tool selection for mixed‑material workshops. Select a matching chipbreaker and holder stiffness to exploit the insert’s strengths: consistent chip control and reproducible surface quality.

FAQ

What applications is this insert best suited for?
The insert is intended for external and internal turning; the AH725 grade supports finishing and medium roughing where material changes are frequent.

Which materials can be machined with this grade?
The AH725‑grade, PVD‑coated carbide insert is designed for reliable performance on Stahl and rostfreier Stahl.

How is the insert secured to the holder?
The insert has a central hole with a cylindrical seat and a single‑side countersink (40°–60°); compatibility depends on holder form, clamp method, tolerance class and size.

What are the key geometry values to consider when programming a job?
Important values are the 55° approach angle, 0.2‑mm corner radius and 3.97‑mm plate thickness, which influence cutting forces and surface finish.
