DPMT070204 AH6225 — Rhombic ISO Turning Insert for Turning (Tungaloy)

DPMT070204 AH6225 is a rhombic, ISO‑standard indexable insert designed for external and internal turning in workshop and production environments, optimised for rostfreier Stahl machining.

• PVD-coated carbide for rostfreier Stahl
• Rhombic ISO DPMT 07 form with 11° clearance
• 0.4 mm nose radius for controlled finish

Precise edge geometry for consistent turning results

The insert combines a PVD-coated carbide substrate with the AH6225 grade to deliver a sharp yet robust cutting edge suited to medium turning operations. This composition provides an advantageous balance between wear resistance and edge stability, which reduces the need for frequent insert changes in mixed‑condition production. The single‑sided chipbreaker supports predictable chip formation, while the modest 0.4 mm nose radius contributes to an improved surface finish without unduly raising cutting forces. For customers evaluating tooling strategies, these characteristics translate into fewer interruptions and steadier part quality during rostfreier Stahl turning.

ISO conformity and simple mechanical compatibility

Built to the ISO DPMT format, the plate’s rhombic profile, 11° clearance, and standard dimensions ensure compatibility with a wide range of holders and boring bars when the holder matches the form, tolerance class, fastening style, size and thickness. The insert includes a cylindrical central hole with a single‑side countersink (40°–60°) for secure clamping and repeatable seating. The 2.38 mm plate thickness and the specified relief geometry make the insert suitable for conventional clamping systems; when a matched seat and clamp are used, repeatable positioning and stable machining follow, supporting predictable cycle times and easier process setup.

Application scope and productivity advantages

Intended for both external and internal turning, the DPMT070204 AH6225 performs well where medium‑duty removal and a consistent surface finish are required. The universal AH6225 grade is formulated for rostfreier Stahl and varying cutting conditions, promoting a stable cutting edge that helps maintain surface quality across interrupted cuts or mixed batches. Selecting the correct chipbreaker and grade for the workpiece and machine stability maximises tool life and contributes to overall productivity gains. If further guidance is needed on matching the insert to specific workpiece alloys or machining parameters, the product data and compatibility notes provide a practical basis for selection.

FAQ

Which materials is the DPMT070204 AH6225 suitable for?
The DPMT070204 AH6225 is a universal grade formulated primarily for rostfreier Stahl and performs well across a range of common turning tasks where a balance of edge sharpness and durability is required.

How is compatibility with toolholders determined?
Compatibility depends on the holder matching the insert’s ISO form, relief angle, tolerance class, fastening method, size and thickness; the DPMT070204 format and the cylindrical hole with countersink enable secure clamping in standard ISO seats.

What does the AH6225 designation and PVD coating provide?
AH6225 denotes a universal PVD‑coated carbide grade created for stable cutting behaviour in rostfreier Stahl; the PVD coating enhances wear resistance and maintains edge integrity under varying cutting conditions.

Is the insert indexable and what chip control is available?
This is a single‑sided indexable insert with a single‑sided chipbreaker; the geometry supports controlled chip formation for consistent surface finishes during medium turning tasks.

What finish and machining performance can be expected with this insert?
With a 0.4 mm nose radius and a sharp, stable edge, the DPMT070204 AH6225 achieves good surface finish and predictable cuts in medium operations; pairing the insert with an appropriate chipbreaker and stable mounting further improves results.
