DNMG 150608 AH6225 turning insert by Tungaloy — PVD-coated carbide, 55° rhomboid

The DNMG 150608 AH6225 is an ISO-format rhomboid turning insert designed for external and internal turning, optimised for reliable performance when machining rostfreier Stahl.

• PVD-coated carbide for improved wear resistance
• Universal grade AH6225 for rostfreier Stahl
• ISO DNMG 55° rhomboid geometry
• Double-sided chipbreaker for stable cutting

Superior edge life and consistent cutting performance

The PVD-coated carbide in grade AH6225 provides a balanced combination of hardness and toughness, giving a sharp, stable cutting edge during medium turning operations. For machining rostfreier Stahl, the coating reduces adhesive wear and helps maintain edge integrity under variable cutting conditions. This results in fewer indexings and more predictable tool life, which supports continuous production and reduces unscheduled downtime. The universal character of the grade makes it suitable where material batches and process stability change frequently.

Precise fit and secure clamping for ISO holders

Designed to the ISO DNMG form, the insert’s rhomboid 55° geometry and standard dimensions ensure compatibility with a wide range of external holders and boring bars; fit is determined by form, relief angle, tolerance class, fastening, size and thickness. The plate is 15 mm in size with a thickness of 6.35 mm and a corner radius of 0.8 mm, while the 0° clearance supports robust engagement. The central cylindrical hole facilitates secure locating and clamping. Verifying the holder’s specifications against these parameters prevents misalignment and preserves the cutting edge, especially during interrupted cuts.

Efficient chip control and flexible application spectrum

The double-sided chipbreaker geometry provides controlled chip formation across a variety of feeds and depths, which simplifies chip evacuation and contributes to consistent surface quality. As a universal solution for external and internal turning, the grade accommodates medium machining strategies and is tolerant of modest variations in cutting data. The ability to flip the insert extends usable life per index and improves cost-efficiency in serial production. Reduced chip scatter and predictable chips also enhance workplace safety and post-process handling.

System thinking for workshop productivity

The insert is supplied as part of a typical ISO insert system: an ISO-format insert, a matching external holder or boring bar, appropriate shim/clamp sets and replacement screws form the complete tooling solution. This system approach ensures straightforward replacement and repeatable positioning when re-indexing or refitting, supporting stable batch performance. For procurement and workshop planning, the Tungaloy grade delivers a practical compromise between durability and versatility, making it a sensible choice for toolrooms that machine rostfreier Stahl alongside other materials.

FAQ

What materials is this insert suited for?
The DNMG 150608 AH6225 insert is principally designed for machining rostfreier Stahl, with the AH6225 grade offering good edge stability for medium turning operations.

How does the PVD coating benefit performance?
A PVD-coated carbide substrate increases wear resistance and reduces adhesion when cutting rostfreier Stahl, which helps sustain cutting-edge integrity and extends usable life between indexings.

Which holders are compatible with the DNMG 150608 geometry?
Compatibility depends on holder form, relief angle and fastening method; the ISO DNMG form and the plate’s dimensions (15 mm × 6.35 mm, 55°) should be matched to the holder’s specification to ensure secure clamping and correct seating.

Can the insert be used for internal turning as well as external turning?
Yes, the insert is suitable for both external and internal turning; the double-sided chipbreaker and the universal AH6225 grade make it versatile across these applications.

What is the manufacturer SKU for ordering or referencing?
Reference SKU for procurement and documentation is 6947235-Tungaloy.
