DGIM 2-020- AH725 — ISO rhombic turning insert, 55° by Tungaloy

The DGIM 2-020- AH725 is an ISO-standard rhombic indexable turning insert designed for both external and internal turning on steel and stainless steels.

• PVD-coated carbide grade AH725 for broad materials compatibility
• ISO rhombic 55° geometry with cylindrical hole
• 30° clearance angle for reliable cutting stability
• Single-sided chipbreaker for controlled chip formation

Consistent cutting performance for reliable production

The insert is engineered to provide stable cutting and repeatable results in production environments. The PVD-coated cemented carbide ensures wear resistance and temperature stability during interrupted cuts and variable feed conditions, which leads to longer tool life and fewer index changes. This translates into higher process efficiency and reduced machine downtime when turning medium and high-strength steels or stainless steels, as the coating improves edge integrity under mixed cutting regimes.

Clear selection criteria to ensure holder compatibility

Compatibility with a toolholder depends on geometry, clearance angle, tolerance class, fastening method, size and thickness; these parameters determine a secure fit and correct rake/relief relationships. The rhombic 55° geometry and the insert’s cylindrical hole are standardised to ISO dimensions, allowing selection of the matching external holder or boring bar with confidence. Choosing the appropriate chipbreaker and the AH725 grade for the specific workpiece material offers the practical benefit of predictable chip control and stable forces during turning.

Process security and material flexibility with AH725

The AH725 grade is a universal, breakage-resistant option optimised for mixed-material shops and smaller tools where reliable performance is critical. With a single-sided chipbreaker and a 30° clearance angle, the insert is suitable for a broad spectrum of turning operations while maintaining surface quality and dimensional stability. The combination of substrate and PVD coating supports consistent tool life, which improves cost-efficiency per component and reduces setup variation between batches.

FAQ

What materials is this insert suitable for?
The DGIM 2-020- AH725 insert from Tungaloy is intended primarily for steel and stainless steels and offers universal performance for varying workpiece materials.

How does the AH725 grade improve process security?
AH725’s PVD-coated cemented carbide substrate on the DGIM 2-020- insert provides wear resistance and fracture toughness, enabling consistent cutting performance and reduced risk of unexpected edge failure.

Which holder characteristics must be checked before fitting the insert?
Ensure the holder matches the ISO geometry, clearance angle (30°), hole type (cylindrical) and the insert size code (2-) to achieve correct seating and clamping for safe turning operations.

Can this insert be used for both external and internal turning?
Yes — the rhombic form and standardised ISO dimensions make the DGIM 2-020- AH725 suitable for both external and internal turning applications.

What advantage does the single-sided chipbreaker give?
A single-sided chipbreaker on this insert supports predictable chip formation and evacuation, improving surface finish and reducing the chance of chip entanglement during continuous turning.
