DCMT070204 AH6225 Indexable Insert for Turning (ISO 070204) — Tungaloy

The DCMT070204 AH6225 is an ISO rhombic indexable insert designed for external and internal turning, engineered to perform on stainless steel with a sharp yet stable cutting edge

• PVD-coated AH6225 carbide for stainless steel
• Rhombic 07 form with 7° relief
• 0.4 mm corner radius for profile and strength
• Cylindrical hole with 40°–60° countersink

Reliable machining performance for stainless steel

The PVD-coated AH6225 grade is formulated as a universal option for machining stainless steel, combining a keen initial cutting edge with sufficient edge stability for medium cutting depths and variable conditions. The coating reduces built-up edge and increases thermal resistance, which contributes to consistent surface finish and longer tool life under interrupted cuts. For operations where a balance of sharpness and wear resistance is required, this grade supports steady productivity and predictable results.

Repeatable clamping and geometry for series production

Compatibility with toolholders is defined by form, relief angle, tolerance, fastening and thickness; the ISO geometry and rhombic 07 shape deliver a positive cutting action and good access to shoulders. The 7° relief angle reduces flank rubbing and helps maintain dimensional accuracy across a production run, while the 0.4 mm corner radius offers a compromise between strength and detail on radiused profiles. The design and single-sided chipbreaker promote stable chip formation and repeatable performance, making this insert suitable where process stability and predictable tool life are primary concerns.

Fast set-up and secure retention reduce downtime

A cylindrical hole with a one-sided countersink (40°–60°) ensures secure mechanical clamping in a matching ISO seat, while the 2.38 mm thickness contributes to rigidity in the clamped assembly. These features support quick insert changes and reliable seating, which reduces set-up time and minimises production interruptions. The overall system concept—ISO insert, appropriate holder, support pads and replacement screws—facilitates straightforward inventory management and rapid replacement during scheduled maintenance or tool changeovers.

FAQ

Which materials is this insert suitable for?
The insert is designed primarily for stainless steel; the AH6225 grade and PVD coating optimise cutting performance and wear resistance when machining stainless materials.

How is holder compatibility determined?
Compatibility depends on insert form, relief angle, tolerance class, fastening, size and thickness; the ISO geometry of the DCMT070204 AH6225 insert matches holders specified for rhombic 07 ISO inserts.

What advantage does a 0.4 mm corner radius provide?
A 0.4 mm corner radius increases edge strength and improves surface finish on radiused features while still allowing precise profiling during medium turning operations.

What does the hole and countersink specification mean for clamping?
The cylindrical hole with a one-sided countersink (40°–60°) ensures stable mechanical clamping in the matching seat, improving repeatability and reducing the risk of insert movement under load.

Which cut types and positions suit this insert?
The geometry and single-sided chipbreaker suit external and internal turning where a balance of edge sharpness and stability is required, particularly for medium-depth cuts in stainless steel.
