DNMG 150412 AH120 Turning insert (ISO 150412) by Tungaloy – PVD-coated cemented carbide, rhombic 55° geometry

DNMG 150412 AH120 is an ISO-standard turning insert designed for external and internal turning; the grade is tailored for applications demanding a sharp edge and consistent process stability

• PVD-coated carbide for wear resistance
• Sharp cutting edge for process security
• Double-sided insert with cylindrical hole
• Rhombic 55° geometry, corner radius 1.2

Longer tool life and consistent edge performance with PVD-coated cemented carbide

The AH120 grade is a PVD-coated cemented carbide developed for turning where a combination of edge sharpness and process reliability is required. The coating reduces abrasive wear and helps maintain cutting-edge integrity under intermittent or continuous cutting conditions. As a result, operators can expect extended tool life and steadier part quality, which reduces the need for frequent index changes and supports predictable production cycles. Where breakout resistance is important, the robust grade composition and edge preparation contribute to fewer edge failures and a more consistent surface finish on turned components.

Secure clamping and ISO compatibility for repeatable setups

The insert is a rhombic 55° geometry with a 1.2 mm corner radius and a plate thickness of 4.76 mm, supplied with a cylindrical mounting hole for positive clamping. As an ISO turning insert, compatibility with holders depends on form, clearance angle, tolerance class, fastening method, size and thickness. The recommended system comprises an ISO insert, a matching external holder or boring bar, a shim/clamp set and replacement screws, ensuring quick changeover and reproducible positioning. The nominal 0° clearance angle and standardised footprint facilitate straightforward integration into existing toolholder portfolios, enabling reliable repeatability across batches.

Operational efficiency through reversible use and suited chip control

The insert is manufactured with a double-sided chipbreaker, permitting reversible indexing to present fresh cutting edges and maximise the number of usable edges per plate. Selecting the appropriate chipbreaker and grade in relation to the workpiece material, cutting mode and machine stability improves chip control and reduces secondary operations. In practice, this leads to shorter cycle times and lower effective tooling costs per component. The geometry and coating combination support a controlled heat build-up at the cutting zone, contributing to consistent dimensional accuracy and an improved surface finish when the cutting parameters are set according to machine and workpiece conditions.

FAQ

What turning tasks is this insert suitable for?
The DNMG 150412 AH120 insert is designed for both external and internal turning where a sharp cutting edge and process security are required; it performs well when a PVD-coated cemented carbide grade is advantageous.

How does the AH120 grade affect tool life?
The AH120 PVD-coated grade enhances wear resistance and edge stability, so the DNMG 150412 insert delivers longer life and more consistent component quality compared with uncoated grades under comparable conditions.

Can the insert be used in standard ISO holders?
Yes, the ISO designation 150412 and the rhombic 55° form permit use in compatible ISO toolholders; compatibility depends on holder form, clearance angle, tolerance class, fastening and plate thickness.

How many usable edges does the insert provide?
As a double-sided insert with a reversible chipbreaker, the DNMG 150412 AH120 allows multiple indexings to present fresh cutting edges, increasing productivity and reducing tooling costs per part.

Which corner radius should be chosen for finishing vs. roughing?
A 1.2 mm corner radius on this insert provides a balance between edge strength and surface finish; smaller radii suit fine finishing while larger radii favour heavy cuts—select the radius to match the machining objective and stability.

Is there any special clamping recommended for this insert?
Use the specified shim/clamp set and replacement screws in a holder that matches the plate form and thickness (4.76 mm) to ensure repeatable positioning and secure clamping during turning operations.
