DCMT 11T302 AH6225 Tungaloy — Indexable turning insert for turning

DCMT11T302 AH6225 is an ISO-standard indexable insert engineered for general-purpose turning, especially where a sharp yet robust cutting edge is required.

Consistent performance for stainless-steel turning

The combination of a PVD-coated surface and the AH6225 cemented carbide grade delivers a balance between wear resistance and edge sharpness, optimised for machining rostfreier Stahl. This configuration reduces flank wear and maintains a sharp cutting edge under variable cutting conditions, which translates into longer periods between indexings and improved throughput. For shops aiming to standardise inserts across medium-duty turning operations, the engineered coating enhances thermal stability and provides reliable tool life without sacrificing surface finish.

Geometry and fit that ensure repeatable results

Designed as a rhombic insert with an effective size of 11 mm, the geometry and relief characteristics determine compatibility with holders and contribute directly to machining stability. The insert features a 3.97 mm thickness, a 0.2 mm radius and a 7° relief, values that influence cutting forces, chip flow and edge strength. The cylindrical hole with a 40°–60° countersink enables secure clamping and repeatable seating in compatible carriers. When the holder, clamp set and screw system match these dimensions and tolerances, runout and vibration are minimised, improving dimensional accuracy and surface quality.

Chip control and system integration for higher productivity

A one-sided chipbreaker layout supports predictable chip formation during both external and internal turning; selecting the chipbreaker and grade according to the workpiece material and machining stability will reduce recutting and cycle times. As an ISO-standard insert, it forms part of a system comprising a suitable external holder or boring bar, a support shim/clamp set and spare screws for rapid replacement. The modular approach simplifies inventory and maintenance, letting workshops react quickly to changing jobs while keeping setup times low and repeatability high. Technical advice is available to help match the insert to the machining strategy and holder geometry.

FAQ

What materials is this insert best suited for?
The DCMT11T302 AH6225 Tungaloy insert is developed primarily for machining rostfreier Stahl, offering a balance of edge sharpness and wear resistance for medium-duty turning.

How does the AH6225 grade affect tool life?
The AH6225 PVD-coated cemented carbide provides improved thermal stability and wear resistance, which helps maintain cutting-edge integrity and extends effective tool life under varying cutting conditions.

Which holder features are required for correct fitting?
Compatibility is determined by insert form, relief angle, tolerance class, fixation method, size and thickness; the rhombic form, 7° relief, 3.97 mm thickness and the cylindrical hole with countersink require a matching carrier and clamp set for secure seating.

Can this insert be used for internal turning or boring?
Yes — with a suitable boring bar or internal holder designed to accept ISO-standard rhombic inserts and to provide stable support, this insert is suitable for both external and internal turning applications.
