DCMT11T312 AH6225 DCMT indexable insert for turning — Tungaloy

The DCMT11T312 AH6225 indexable insert is an ISO‑standard rhombic turning insert optimised for medium turning of rostfreien Stahl and intended for use with compatible external holders or boring bars.

• ISO rhombic turning insert DCMT11T312 AH6225
• PVD‑coated carbide for rostfreien Stahl
• 1.2 mm corner radius for robust cutting edges
• 7° relief angle and 3.97 mm plate thickness

Consistent edge life through the AH6225 grade

The PVD‑coated carbide grade AH6225 is engineered for a balance of sharpness and edge stability in medium turning operations. As a PVD‑coated material, it offers improved wear resistance and temperature tolerance compared with uncoated grades, which translates into longer intervals between indexings and fewer unexpected tool changes. The single‑sided chipbreaker supports controlled chip formation during interrupted cuts and variable conditions, thereby enhancing process reliability and repeatability for workshop production runs.

Quick set-up and secure clamping reduce machine downtime

Conformance to ISO geometry and the rhombic plate form ensure broad compatibility with standard holders; the insert’s rhombic shape and with hole configuration (cylindrical hole with single‑side countersink 40°–60°) permit precise, repeatable mounting. The combination of an accurately defined plate thickness of 3.97 mm, plate size 11 and the secure hole/countersink arrangement reduces set‑up time and minimises the risk of misalignment. Together, these features contribute to stable cutting conditions and a predictable surface finish across series production.

Practical selection and production benefits for workshops

A corner radius of 1.2 mm delivers a compromise between edge strength and finish, making it well suited to general turning tasks where both tool life and surface quality matter. The 7° relief angle supports effective cutting forces and prevents premature flank wear on longer tool engagements. Choosing the DCMT11T312 AH6225 for medium turning of rostfreien Stahl yields improved cycle times and consistent component quality; further cutting data and recommended parameters are available for integration into existing process sheets and CAM strategies.

FAQ

Which materials is this insert intended for?
The DCMT11T312 AH6225 insert is specified as a universal grade for rostfreien Stahl and performs well across a range of stainless applications under medium cutting conditions.

What is the corner radius and how does it influence performance?
The 1.2 mm corner radius increases edge robustness and improves resistance to chipping, making the insert suitable for general turning where a balance of surface finish and tool life is required.

How is the insert secured in the holder?
The insert features a cylindrical hole with a single‑side countersink (40°–60°) for secure, repeatable clamping in ISO‑compatible external holders and boring bars.

What coating and substrate does the grade use?
Grade AH6225 is a PVD‑coated carbide designed to combine sharpness with thermal and abrasive wear resistance for consistent performance.

Can this insert be used for interrupted cuts or variable conditions?
Yes, the combination of the robust corner radius, stable cutting edge geometry and single‑sided chipbreaker makes the insert suitable for interrupted cuts and fluctuating machining conditions.
