DPMT 070208 AH6225 ISO turning insert for external and internal turning — Tungaloy

The DPMT 070208 AH6225 is an ISO‑standard rhombic turning insert designed for external and internal turning of stainless steels, offering a balanced mix of sharpness and edge stability for varying cutting conditions.

• PVD-coated carbide AH6225 for stainless steel
• 0.8 mm corner radius for stable cutting
• ISO DPMT 070208 form for holder compatibility

Improve process stability with a universal cutting grade

The PVD‑coated AH6225 grade is formulated as a universal option for machining stainless steels, combining a sharp cutting edge with robust wear resistance. In practice, this means a lower risk of built‑up edge and more predictable tool life when switching between batches or tolerances. Because the grade balances edge sharpness and toughness, it is particularly suitable for medium cutting parameters and mixed production runs where consistent component quality matters. The coating increases resistance to adhesive wear and heat, supporting higher productivity without sacrificing surface finish.

Precise geometry for repeatable results

The rhombic insert geometry with a 55° included angle and a 0.8 mm corner radius gives a reliable contact area and controlled force distribution during cuts. A relief angle of 11° helps to reduce rubbing while the 2.38 mm thickness ensures mechanical stability in the clamping. The insert features a cylindrical hole with a one‑sided countersink (40°–60°) for secure fixation in standard ISO holders; compatibility is determined by form, relief angle, tolerance class, attachment method, size and thickness. Using ISO‑conforming inserts simplifies inventory and enables predictable seating in a wide range of external and internal turning holders.

Practical application and system compatibility

Designed for indexable turning systems, the insert integrates with a suitable external holder or boring bar together with the correct shim and clamping screws to form a complete cutting system. The one‑sided chipbreaker supports effective chip control when paired with appropriate feeds and depths of cut; selecting the chipbreaker and grade to match material, rigidity and machining strategy reduces cycle times and scrap. For shops seeking quick conversion between operations, the ISO form and standardised mounting ensure fast, repeatable insert changes and consistent component quality across shifts.

FAQ

Which materials is the insert suited for?
The DPMT 070208 AH6225 turning insert from Tungaloy is specified for machining stainless steels and offers a universal balance of edge sharpness and toughness for medium cutting conditions.

Can this insert be used for both external and internal turning?
Yes, the ISO rhombic geometry and clamping hole make the insert compatible with standard external holders and boring bars for internal turning when mounted with the correct holder and shim.

What does the AH6225 grade offer compared with other grades?
The AH6225 PVD‑coated cemented carbide provides improved resistance to adhesive wear and thermal loads while preserving a relatively sharp cutting edge, which supports stable performance across varying stainless steel batches.

How does the insert secure in the holder?
Fixation is achieved via the central cylindrical hole with a one‑sided countersink; compatibility depends on matching form, relief, tolerance class, attachment method, size and thickness to the chosen ISO holder.
