DCMT11T312 AH8005 indexable turning insert — PVD-coated carbide, 1.2 mm radius | Tungaloy

The DCMT11T312 AH8005 Tungaloy insert is a PVD-coated carbide indexable insert for stable external and internal turning of heat-resistant alloys and hard materials.

• DCMT 11T312 geometry, ISO standard
• PVD-coated carbide grade AH8005
• 1.2 mm corner radius for strong edge
• Cylindrical hole with 40°–60° countersink

Consistent edge life for demanding materials

The combination of a PVD-coated surface and the AH8005 carbide grade is engineered for wear resistance when machining heat-resistant alloys and other hard workpiece materials. The PVD layer reduces flank wear and helps maintain a sharp cutting edge at elevated temperatures, which means fewer index changes and longer uninterrupted machining cycles. For production environments this translates into improved process stability and lower overall tooling consumption per component, supporting efficient batch runs and predictable throughput.

Secure clamping and predictable repeatability

The rhombic form with the 11 mm inscribed circle and the 3.97 mm plate thickness is designed to match ISO holders and boring bars; compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness. The insert features a cylindrical hole with one-sided countersink (40°–60°) for reliable seating and torque transmission in standard clamps. A 7° clearance angle and the 55° included angle ensure a robust cutting geometry that resists edge chipping under interrupted cuts, while the 1.2 mm corner radius balances edge strength and surface finish for many turning operations.

Better chip control and fewer rework cycles

The one-sided chipbreaker offers controlled chip formation for a wide range of turning tasks, reducing the risk of long swarf and making coolant and chip evacuation more efficient. Controlled chips and stable cutting conditions help achieve a consistent surface quality and reduce secondary operations. Selecting the appropriate chipbreaker and the AH8005 grade according to workpiece material and machine stability helps to maximise tool life and machining economy, particularly for medium-to-high cutting speeds with heat-resistant alloys.

Fast integration into existing tool systems

As part of an ISO insert system, the plate forms a complete tooling solution with the matching external holder or boring bar, shim/clamp set and replacement screws. Systematic replacement and straightforward geometry identification reduce setup times and simplify inventory management. Clear labelling with the ISO designation 11T312 and manufacturer references speeds up reordering and ensures the correct grade and geometry are used for each application, supporting consistent production quality.

FAQ

What materials is this insert suitable for?
The DCMT11T312 AH8005 insert is intended for heat-resistant alloys and other hard materials; the AH8005 grade and PVD coating are optimised for wear resistance in such applications.

How does the 1.2 mm corner radius affect performance?
A 1.2 mm corner radius increases edge strength and improves resistance to chipping, which is beneficial for interrupted cuts and heavier feed conditions while still delivering a good surface finish.

Which holders are compatible with this ISO insert?
Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness; the insert follows ISO geometry and fits standard DCMT-compatible external holders and boring bars when those parameters match.

Is the insert reversible or indexable?
The component is an indexable insert with multiple cutting edges; when one edge wears, the insert can be indexed to a fresh edge to extend tool life.
