DNMG150612 AH6225 Tungaloy turning insert — PVD-coated carbide, rhombic 15 mm

The DNMG150612 AH6225 Tungaloy insert is an ISO-standard indexable plate for turning, engineered for stable cutting in stainless-steel applications.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel turning
• Rhombic 15 mm plate, 6.35 mm thick
• Double-sided chipbreaker, cylindrical hole

Consistent cutting performance where it counts

The PVD-coated carbide composition and AH6225 grade deliver a combination of sharpness and edge stability that is particularly effective in machining stainless steels under varying conditions. The hard substrate supports a defined cutting edge while the PVD layer increases wear resistance, resulting in consistent results across medium cutting depths. This translates into predictable tool life and a reduced need for frequent index changes, which supports higher process efficiency on production turning centres.

Geometry and system compatibility for secure clamping

A rhombic plate profile with a 1.2 mm corner radius and 0° clearance angle ensures predictable engagement and a favourable cutting geometry for both external and internal turning. The plate’s double-sided chipbreaker and cylindrical hole permit stable seating and straightforward indexing in ISO holders; compatibility is governed by form, clearance angle, tolerance class, fastening method, size and thickness. Selecting the correct holder and clamp ensures secure fixation and repeatable positioning, which benefits surface finish and dimensional consistency.

Practical benefits for workshop productivity

Using an ISO-standard insert in a matched system reduces setup time and simplifies inventory management. The DNMG150612 variant offers a balance between edge sharpness and robustness, which can lead to reduced downtime and fewer rejects when turning challenging alloys. Matching the AH6225 grade and chipbreaker style to the specific stainless-steel grade and machining parameters optimises chip control and lowers the risk of built-up edge. For workshops seeking predictable throughput and reproducible finishes, the insert’s geometry and PVD coating contribute directly to operational reliability.

FAQ

Is this insert suitable for stainless-steel turning?
Yes. The DNMG150612 AH6225 Tungaloy insert is specifically formulated for stainless steel machining, combining a sharp cutting edge with PVD wear resistance to handle medium-duty turning tasks.

Which holder types are compatible with this insert?
Compatibility requires an ISO-standard holder with matching form, tolerance class, fastening and size; the insert seats in holders designed for rhombic DNMG plates and uses the cylindrical hole for secure clamping.

What is the corner radius and why does it matter?
The corner radius is 1.2 mm; this radius balances edge strength and surface finish, making the plate suitable for general-purpose turning where a compromise between robustness and precision is needed.

Is the insert reversible or single-use?
The plate is double-sided with a chipbreaker on each side, allowing indexing to the second cutting edge to extend usable life before replacement.

What coating and material are used on the insert?
The insert is manufactured from carbide and finished with a PVD coating; the grade is AH6225, optimised for performance on stainless steels.
