DNMG110404 AH120 turning insert by Tungaloy

The DNMG110404 AH120 is an ISO‑standard rhombic turning insert designed for external and internal turning where a sharp cutting edge and process reliability are required.

• PVD-coated carbide grade AH120
• Sharp cutting edge for process security
• ISO‑standard rhombic insert, 55° cutting angle
• Double-sided chipbreaker with cylindrical hole

Precision grade for stable production and longer tool life

The PVD-coated AH120 grade combines a hard coating with a carbide substrate to provide enhanced wear resistance and stable cutting-edge behaviour during continuous turning. This indexable insert offers predictable performance in repetitive operations, which reduces unplanned stoppages and contributes to lower total machining costs. The coating process improves adhesion and edge protection; for users unfamiliar with coatings, PVD (physical vapour deposition) forms a thin, wear-resistant layer that helps maintain a sharp cutting edge under moderate to demanding cutting conditions.

ISO compatibility and practical holder selection

This insert conforms to the ISO turning plate family and its compatibility with a toolholder is governed by geometry factors such as form, free angle (0°), tolerance class, fastening method, size and thickness. For reliable clamping and repeatable results, match the rhombic plate and the cylindrical hole to a holder designed for DNMG plates. Selecting the correct chipbreaker and grade should be done according to the workpiece material and machining stability; choosing the AH120 grade is advantageous when a combination of sharpness and process security is the priority.

Geometry that balances strength and finish

With its rhombic form, an effective 55° cutting angle and a 0.4 mm corner radius, the insert delivers a compromise between edge strength and the ability to produce a fine surface. The 4.76 mm thickness and double-sided design increase the number of indexable cutting edges per insert, improving cost efficiency. The geometry supports both roughing and finishing passes when paired with the right chipbreaker; a smaller corner radius reduces cutting forces and improves finish, while the rhombic shape allows flexible approach angles in external and internal turning.

Productivity and application guidance for workshop use

When fitted correctly into a matched holder and used with appropriate machining parameters, this Tungaloy insert helps maintain consistent part quality and extends toollife, which supports higher throughput. The double-sided nature and the robust grade reduce the frequency of insert changes, lowering downtime. For applications where predictable chip formation and stable cutting are required, this indexable plate is a practical choice; operators benefit from a clear selection path—choose chipbreaker and grade to suit the material, the machining allowance and the rigidity of the setup.

FAQ

Which machining tasks suit this insert best?
The DNMG110404 AH120 Tungaloy insert is intended for external and internal turning where a sharp cutting edge and process security are required; it is best applied where repeatable performance and controlled chip formation are important.

How is the insert fixed to the toolholder?
Compatibility is determined by form, free angle, tolerance class, fastening, size and thickness; the DNMG110404 uses a cylindrical hole for reliable clamping in holders designed for ISO DNMG plates.

What does the AH120 grade provide?
AH120 is a PVD-coated carbide grade offering enhanced wear resistance and protection against chipping, making it suitable for operations that demand a sharp edge and stable cutting performance.

Can the insert be indexed and reused?
Yes, the insert is double-sided and indexable; flipping to a fresh cutting edge extends usable life and improves overall cost efficiency.

How do geometry features affect part quality?
The 55° cutting angle and 0.4 mm corner radius balance edge strength and surface finish; smaller radii help achieve finer finishes while the rhombic shape allows versatile approach angles.
