DNMG 150404 AH6225 — ISO turning insert by Tungaloy (PVD-coated carbide, 55°)

The DNMG150404 AH6225 Tungaloy insert is a rhombic, ISO-standard indexable insert designed for external and internal turning, offering a stable, sharp cutting edge for mid-range machining of stainless steels

• ISO rhombic insert DNMG150404
• PVD-coated carbide AH6225
• Optimised for stainless steel machining

High productivity from a stable cutting geometry

The combination of PVD-coated carbide and the AH6225 grade provides a dependable balance between edge sharpness and wear resistance, which directly improves cycle times in medium-duty turning operations. The coating supports reduced built-up edge formation on stainless steel, while the substrate material maintains a durable cutting edge under variable conditions. This results in fewer indexings and more consistent part quality, so machining processes run more predictably and with improved throughput.

Designed for secure clamping and simple integration

Compatibility with clamping systems is governed by form, clearance angle, tolerance class, fastening, size and thickness; this insert matches ISO specifications for straightforward installation in matched holders and boring bars. The rhombic plate with a cylindrical hole and the specified dimensions (15 mm inscribed circle, 4.76 mm thickness) ensure reliable seating and repeatable positioning, reducing setup time and minimising the risk of inaccurate seating that can affect surface finish and tool life.

Versatile chip control and application-focused performance

The double-sided chipbreaker and a 0° clearance specification support stable chip formation across interrupted and continuous cutting conditions, particularly when machining rostfreier Stahl (stainless steel). The small 0.4 mm corner radius assists in producing fine surface finishes while limiting radial engagement for lower cutting forces where required. Together, these features make the grade suitable for a wide range of turning tasks where balance between tool life and surface integrity is essential.
