DCMT 11T312 AH6225 Wendeplatten - Tungaloy

Take advantage of the combination of a PVD-coated carbide grade (AH6225) and a sharp yet stable cutting edge to ensure consistent mid-range turning performance in stainless steel. Order the DCMT11T312 AH6225 turning insert directly via Metav Werkzeuge or ask our consultants if needed.

DCMT 11T312 AH6225 turning insert (ISO) by Tungaloy — 7° clearance, 1.2 mm corner radius

DCMT11T312 AH6225 is an ISO‑standard rhombic indexable turning insert designed for general turning tasks, optimised for stainless steel and versatile production environments.

• PVD-coated carbide AH6225 for stainless steel
• 1.2 mm corner radius for robust edge form
• 7° clearance angle for stable cutting
• Rhombic ISO shape DCMT 11T312

Consistent cutting performance for difficult-to-cut stainless steel

The insert combines a PVD-coated carbide substrate with the AH6225 grade to balance sharpness and edge stability. This makes it particularly suitable for machining stainless steel where adhesion and work‑hardening are common challenges. The coating reduces built‑up edge and improves wear resistance, while the substrate toughness supports interrupted cuts. As a result, the component life cycle is extended and downtime for insert changes is reduced, supporting a more reliable production flow.

Secure clamping and universal ISO compatibility

The rhombic form (DCMT 11T312) and the specified hole geometry — cylindrical hole with single‑side countersink (40°–60°) — ensure repeatable seating in standard ISO holders. The 3.97 mm plate thickness and the tolerance match required by ISO systems allow predictable tool overhang and clamping forces, which maintain cutting stability. Choosing a compatible external holder or boring bar, together with the correct clamping set and replacement screws, prevents micro‑movement and preserves the intended cutting geometry during longer cycles.

Process benefits: chip control and economy in medium duty turning

With a 1.2 mm corner radius and a single‑sided chipbreaker, the insert manages chip formation reliably under varying cutting conditions; this reduces risk of entanglement and promotes consistent surface finish. The grade AH6225 is optimised as a universal choice for stainless steel, offering good flank wear behaviour and stable edge retention for medium material removal rates. In practical terms, shops benefit from fewer indexings, predictable part quality and a favourable cost‑per‑part ratio when the insert is paired with a matching holder and machining strategy.

FAQ

What materials is this insert suited for?
The DCMT11T312 AH6225 insert is formulated for stainless steel and performs well in a range of medium‑duty turning applications where adhesion and work‑hardening are concerns.

How does the AH6225 grade affect tool life?
AH6225’s PVD coating and carbide substrate provide a balance of wear resistance and edge toughness, extending life on stainless steel compared with uncoated grades under comparable conditions.

Which holders are compatible with this insert?
Compatibility depends on form, clearance, tolerance class, fastening, size and thickness; select an ISO‑compatible external holder or boring bar designed for DCMT inserts and ensure correct clamping hardware is used.
