DNMG 150612 AH6235 ISO turning insert, PVD-coated carbide, with cylindrical hole — Tungaloy

A DNMG150612 AH6235 ISO turning insert engineered for reliable external and internal turning, offering high fracture resistance for interrupted cuts and demanding rostfreie Stahl applications

*PVD-coated carbide grade AH6235 *Optimised for rostfreier Stahl and interrupted cuts *Rhombic insert with 55° cutting angle *Double-sided chipbreaker with cylindrical hole

Consistent machining of rostfreier Stahl and difficult alloys

The AH6235 grade is a PVD-coated carbide designed to combine toughness with wear resistance, which helps when machining rostfreier Stahl or components prone to built-up edge. The tougher substrate reduces the risk of chipping during interruptions, while the coating supports thermal stability at elevated cutting temperatures. This balance results in fewer insert changes and more reliable cycle times, making the geometry a practical choice where repeatability and uptime matter.

Reduced setup time through ISO compatibility and secure clamping

Adherence to ISO form and dimensions ensures predictable fitment in standard toolholders; compatibility depends on element shape, clearance angle, tolerance class, fastening and thickness. The rhombic outline with a cylindrical hole permits positive clamping and straightforward indexation, so insert changes are fast and secure. Clear specification of holder type and clamping hardware avoids trial-and-error, supporting smooth changeovers and reduced non-productive time.

Geometry and chip control that raise productivity

The 55° cutting angle and 1.2 mm corner radius produce a compromise between strength and surface finish: robust enough for interrupted cuts yet suitable for achieving acceptable roughness on external and internal profiles. The double-sided chipbreaker improves fragmentation and evacuation, lowering the risk of built-up edge and stabilising cutting forces. Together these design choices enable higher average metal removal rates while maintaining dimensional control across batches.

Practical integration and recommended system setup

For a complete machining system, pair the insert with a compatible external holder or boring bar, plus a matching shim/clamp set and spare fasteners. The insert is part of the ISO turning insert series and performs best when chipbreaker style and grade are selected to match workpiece stability and feed rate. When facing high breakout risk or poor part support, the AH6235 grade and its chip control features offer a safer margin against premature tool failure, translating into longer tool life and fewer interruptions.

FAQ

What materials is this insert suitable for? The DNMG150612 AH6235 insert from Tungaloy (SKU TUN6886140) is optimised for rostfreier Stahl and alloys where interrupted cuts or breakout risk require a tougher grade.

Is the geometry suitable for internal turning and profiling? Yes, the rhombic form with a 55° cutting angle and a 1.2 mm corner radius provides a good balance of strength and access for internal turning and light profiling tasks.

How does the chipbreaker affect performance? The double-sided chipbreaker on this Tungaloy insert improves fragmentation and evacuation, reducing built-up edge and helping to maintain stable cutting forces during continuous production.

How should the insert be clamped in the holder? Secure clamping via the cylindrical hole and correct shim/clamp selection is essential; compatibility is determined by insert form, clearance angle, tolerance class, fastening, size and thickness.

Which system components are typically required for use? A standard setup includes the ISO insert, a matching external holder or boring bar, a shim/clamp set and replacement screws to ensure safe and repeatable mounting.
