DNMG150404 AH6225 DNMG turning insert — Tungaloy, PVD-coated carbide, 55°

The DNMG150404 AH6225 is an ISO-standard indexable insert for external and internal turning, designed for medium machining of stainless steel and variable cutting conditions.

• ISO DNMG geometry, 55° lead angle
• PVD-coated carbide grade AH6225
• 0.4 mm corner radius for precision
• Double-sided chipbreaker, rhombic shape

Consistent cutting performance for stainless steel

The combination of a PVD-coated carbide substrate and the AH6225 grade delivers a balance between edge sharpness and robustness, specifically tuned for stainless steel. The coating reduces adhesion and helps to maintain a stable cutting edge during interrupted cuts and variable feeds, which supports predictable tool life and repeatable component quality. For shops moving between finishing and semi-finishing tasks, this insert offers a dependable compromise between surface integrity and productivity.

Design and dimensions that aid rigidity and accuracy

The ISO DNMG150404 geometry with a 55° included angle and a 0.4 mm corner radius provides controlled contact conditions and reduced radial forces, aiding dimensional stability on slender workpieces. The insert’s 4.76 mm plate thickness contributes to stiffness when mounted in a suitable holder; the presence of a cylindrical clamp hole ensures secure fastening and correct seating. Compatibility with the chosen holder is governed by form, clearance angle, tolerance class, fastening, size and thickness, so matching the DNMG geometry to a holder rated for ISO DNMG plates ensures consistent clamping and repeatable results.

Efficient chip control and economical indexing

A double-sided chipbreaker and two usable sides per face reduce tooling costs and machine downtime through economical indexing. The rhombic plate form enables access to both external and internal turning applications where a 55° lead angle is advantageous. For manufacturing environments that demand constant output and minimal tool changes, this insert supports continuous operation and straightforward handling during index changes, contributing to lower operating costs over multiple workpieces without sacrificing process reliability.

Practical advantages for process planning

Because the insert is ISO-standardised, integration into existing toolsets is straightforward: the ISO designation simplifies procurement and storage, while the AH6225 grade provides broad applicability across stainless steel variants under medium cutting conditions. The PVD coating enhances wear resistance and reduces built-up edge tendencies, which in turn helps to maintain consistent surface finish and dimensional control. When selecting cutting parameters, consider the insert’s balance of sharpness and stability to exploit its strengths in both finishing passes and light semi-finishing.
