DCMT070208 AH6225 indexable turning insert – PVD-coated carbide for stainless steels, Tungaloy

The DCMT070208 AH6225 is an ISO-standard indexable turning insert designed for external and internal turning, engineered to provide a sharp and durable cutting edge in mid-range stainless-steel machining.

• PVD-coated cemented carbide AH6225
• Optimised for machining stainless steels
• ISO DCMT 070208 rhombic insert
• 0.8 mm nose radius and 7° clearance

Improved tool life and predictable cycle times

The PVD-coated cemented carbide grade AH6225 combines a hard wear-resistant surface with a tough substrate to resist edge chipping during intermittent cuts. This balance reduces unexpected tool changes and supports stable chip formation, which directly contributes to lower production costs per component and fewer process interruptions. For machining operations where conditions vary, the coating’s thermal resistance enhances wear behaviour, so productivity remains consistent across series production.

Better surface finish with balanced geometry

A 0.8 mm nose radius together with the 7° clearance produces an effective compromise between strength and surface quality: the modest radius helps maintain edge integrity under higher feed rates while still delivering a good finish on ferritic and austenitic stainless steels. The insert’s geometry spreads cutting forces across the edge to avoid premature notch wear; in practice, this means fewer rework cycles and a more reliable dimensional finish on turned parts.

Clear guidance on holder compatibility and mounting

The insert follows the ISO DCMT 070208 specification and is rhombic in form with a 2.38 mm thickness and a size 07 designation, which makes it compatible with a wide range of standard external holders and boring bars designed for this family. The insert is supplied with hole and a cylindrical hole plus single-sided countersink (40°–60°), enabling secure clamping and straightforward replacement. Compatibility is determined by holder form, clearance angle, tolerance class, fastening method, size and thickness, so matching the insert to the correct clamping system ensures repeatable seating and reliable cutting performance.

Practical selection for reliable chip control and applications

Equipped with a single-sided chipbreaker, this grade suits a variety of feed rates and depths of cut typically used in general turning tasks. The combination of chipbreaker design and AH6225’s coating supports efficient chip evacuation when machining stainless steels, reducing the risk of built-up edge. Select this insert for external and internal turning where a sharp but resilient edge is needed; for unstable setups or heavy interrupted cuts, consider a larger nose radius or a more robust geometry.

FAQ

Is the DCMT070208 AH6225 suitable for machining stainless steels?
The Tungaloy DCMT070208 AH6225 insert is specifically developed for stainless-steel applications; the PVD-coated cemented carbide grade AH6225 delivers a sharp, wear-resistant edge adapted to the demands of austenitic and martensitic stainless materials.

What surface finish can be expected with a 0.8 mm nose radius?
A 0.8 mm nose radius on this insert balances edge strength and finish quality, providing good surface results at moderate to higher feed rates while reducing the likelihood of edge chipping compared with very small radii.

Which holders are compatible with this DCMT insert?
Compatibility requires a holder designed for DCMT 070208 geometry; the insert’s form, 7° clearance, size and 2.38 mm thickness must match the holder’s seating, clamping and tolerance class for secure and repeatable mounting.

Can this insert be used for internal turning operations?
Yes, the insert is suitable for both external and internal turning; when used for internal turning, ensure the chosen boring bar offers sufficient rigidity and correct seating for the DCMT070208 geometry.

How does AH6225 compare to tougher grades for interrupted cuts?
AH6225 is a universal grade optimised for stainless steels, providing a sharp, stable edge for medium machining. For heavy interrupted cutting or highly unstable setups, a tougher grade with a larger edge allowance may be preferable.
