DNMG110412 AH120 indexable turning insert — PVD-coated carbide, rhombic 55° by Tungaloy

DNMG110412 AH120 is an ISO rhombic indexable turning insert designed for external and internal turning in ISO tool systems

• PVD-coated carbide grade AH120
• Rhombic ISO DNMG form, 55° included angle
• 1.2 mm corner radius for precise finishes
• Double-sided chipbreaker with central cylindrical hole

Consistent cutting performance for demanding turning tasks

The PVD-coated carbide grade AH120 provides a combination of wear resistance and a sharp cutting edge that supports stable cutting processes. PVD coating improves resistance to abrasion and adhesion at elevated temperatures; in practice this means longer edge life and fewer interruptions for index changes. As an ISO-design insert, the component supplies a reproducible cutting geometry that helps maintain part tolerances and surface quality over long production runs. The result is predictable tool life and higher throughput in repeat operations.

Seamless integration into ISO holders and clamping systems

Compatibility with toolholders depends on the insert’s form, relief angle, tolerance class, fastening method, size and thickness. The DNMG110412 format with a 55° included angle and a 0° relief angle suits a wide range of external holders and boring bars. The central cylindrical hole provides positive location and secure fastening with standard screws and clamp sets, enabling reliable clamping even under interrupted cuts. Integrating this indexable insert into an established tool system reduces setup times and simplifies requalification of fixtures.

Reliable chip control and practical application guidance

The double-sided chipbreaker design supports controlled chip formation for a variety of turning conditions, making the insert appropriate where consistent chips and process security are required. The 1.2 mm corner radius balances edge strength and surface finish: larger radii increase robustness, while smaller radii can improve detail and contour fidelity. For best results, pair the insert with a rigid holder, select a chipbreaker and grade suited to the workpiece material and machining stability, and monitor feed and speed to match the application’s heat generation and vibration characteristics. The machining system typically comprises the ISO insert, a matching external holder or boring bar, a support/clamping set and replacement screws.

FAQ

Which materials is this insert intended for?
The DNMG110412 AH120 insert from Tungaloy is a PVD-coated carbide grade formulated for turning applications; it is described as wear- and fracture-resistant and is selected where a sharp cutting edge and process security are required.

How is compatibility with a toolholder determined?
Compatibility depends on the insert form, relief angle, tolerance class, fastening method, size and thickness; matching these parameters to a toolholder ensures correct seating and clamping of the DNMG110412 geometry.

What chip control can be expected from this insert?
The double-sided chipbreaker on the AH120 grade promotes consistent chip formation across typical turning conditions; selecting the correct chipbreaker and machining parameters helps to maintain stable chips and minimise secondary operations.

Is the insert indexable and how is it clamped?
The DNMG110412 is an indexable insert featuring a central cylindrical hole for secure fastening; indexing and reorientation are performed according to the holder and clamping system used.

What does the complete machining system include?
A complete system for this insert normally comprises the ISO insert itself, a matching external holder or boring bar, an underlay/clamp set and replacement screws to ensure secure mounting and repeatable positioning.
