DPMT 11T308 AH6225 ISO rhombic turning insert by Tungaloy — PVD-coated carbide, 55° geometry

DPMT 11T308 AH6225 is an ISO‑standard rhombic turning insert suited to external and internal turning, designed for reliable performance in medium machining of stainless steels.

• ISO rhombic insert DPMT 11T308
• PVD-coated carbide AH6225
• 55° cutting geometry, 11° relief
• One-sided chipbreaker, with hole

Consistent cutting performance for stainless-steel applications

The PVD-coated AH6225 grade combines a sharp, stable cutting edge with a coating that enhances wear resistance under variable conditions. This composition is aimed at delivering stable chip formation and longer edge life during medium-duty turning of stainless steels, reducing unexpected tool changes and improving spindle uptime. The description of the grade highlights its universality: it balances edge sharpness with robustness so that changeovers between different stainless materials remain efficient and predictable.

Geometry and edge design that improve surface finish and tool life

The rhombic geometry with a 55° lead angle and 11° relief lowers cutting forces and helps maintain a steady cutting action, while the 0.8 mm corner radius supports smoother transitions and improved surface quality on workpieces. The one-sided chipbreaker is engineered to control chip flow for common turning operations, and the central hole with cylindrical bore plus a single-sided countersink (40°–60°) ensures secure clamping and repeatable positioning in compatible holders. These design choices reduce vibration and contribute to consistent results in serial production.

Integration into existing tool systems and practical advantages

As an ISO insert, the DPMT 11T308 fits industry‑standard holders when matched for form, clearance angle, tolerance class, fastening method, size and thickness. The plate thickness of 3.97 mm supports robust clamping, and the universal AH6225 grade simplifies inventory by covering a broad range of stainless‑steel machining tasks. For workshops aiming for predictable process windows and reduced set‑up time, this insert offers a pragmatic balance between economy and performance.

FAQ

What materials is this insert best suited for?
The DPMT 11T308 AH6225 insert is optimised for stainless steels, offering a combination of edge sharpness and wear resistance suitable for medium machining of common stainless‑steel grades.

How does the insert ensure reliable clamping?
The insert’s central cylindrical hole with a single‑sided countersink (40°–60°) and a plate thickness of 3.97 mm provide secure seating and repeatable positioning in compatible ISO holders, helping to maintain process stability with the DPMT 11T308 AH6225.

Which features support improved chip control?
The one‑sided chipbreaker combined with the rhombic geometry directs chips away from the cutting zone and contributes to consistent chip formation when machining stainless steels with the AH6225 grade.

Can this insert be used for both external and internal turning?
Yes, the ISO‑design and geometry of the DPMT 11T308 make it suitable for both external and internal turning operations when the correct holder and machining parameters are selected.

How does the AH6225 grade affect tool life and surface finish?
AH6225 delivers a sharp but stable cutting edge that helps achieve good surface finishes while providing sufficient wear resistance under varying cutting conditions, resulting in consistent life performance across typical stainless‑steel turning tasks.
