DNMG150408 AH6235 — DNMG ISO turning insert for turning by Tungaloy

A DNMG150408 AH6235 indexable turning insert optimised for external and internal turning operations on stainless steels and for interrupted cuts, designed to work with ISO holders and standard clamping systems.

• PVD-coated carbide for wear resistance
• Designed for stainless steel and interrupted cuts
• Rhombic 55° geometry for versatile turning
• Double-sided chipbreaker, with cylindrical hole

Consistent cutting performance for demanding stainless-steel work

The combination of a PVD-coated carbide grade and a tougher substrate (AH6235) gives a balance of toughness and wear resistance that is particularly suitable for stainless steel and other materials prone to work hardening. The coating reduces adhesive wear and improves heat resistance at higher cutting speeds, while the tougher substrate helps absorb shocks during interrupted cuts, lowering the risk of flank breakouts. This results in fewer tool changes and more predictable production cycles, supporting leaner processes on the shop floor.

Geometry and clamping: why form and fit matter

The rhombic 55° geometry and the specified 0.8 mm corner radius provide versatility for both finishing and light-roughing passes. The insert’s 0° clearance angle and plate thickness of 4.76 mm contribute to secure seating and repeatable cutting positions. The insert is supplied with a cylindrical hole and a double-sided chipbreaker, allowing indexing and simple rotation to present a fresh cutting edge. Compatibility with a holder is determined by form, clearance, tolerance class, fixing arrangement, size and thickness, so pairing with an ISO-matched external holder or boring bar is recommended for optimal stability.

Improved process reliability and surface outcomes

A double-sided chipbreaker promotes reliable chip control and reduces clogging on interrupted or unstable feeds, which supports steady cutting forces and more consistent surface finishes. When combined with the AH6235 grade and PVD coating, this insert helps maintain a stable cutting edge for longer, reducing scrap and rework. Choosing the correct chipbreaker and grade according to component material and machine stability will directly influence cycle times and tool-life economics, enabling more efficient production planning and cost allocation.

Application guidance and system setup

This insert is intended for turning applications and is used as part of an ISO insert system — the complete set-up typically comprises the ISO turning insert, a compatible external holder or boring bar, shim/clamping set and replacement fastening screws. For best results in serial production, select the chipbreaker and grade to suit the workpiece material and machining conditions; AH6235 is advised for stainless steels and operations with higher breakout risk. The insert’s design supports both external and internal turning tasks, and its indexable nature provides quick edge changes to keep machines productive.

FAQ

What materials is this insert suitable for?
The DNMG150408 AH6235 insert is specified for stainless steel and is designed to perform well in interrupted cuts and applications with an elevated risk of breakout.

How does the AH6235 grade differ from other coatings?
The AH6235 grade is a PVD-coated carbide combination that emphasises toughness and adhesion resistance, offering better performance on work-harden­ing materials compared with harder, more brittle coatings.

Can the insert be indexed to present a fresh edge?
Yes. The insert is double-sided with a cylindrical hole and a double-sided chipbreaker, enabling indexing to a new cutting edge for extended service life.

What holder compatibility should be checked before fitting?
Compatibility depends on form, clearance angle, tolerance class, fixing style, size and thickness; match the insert to an ISO-compliant external holder or boring bar and use the correct shim/clamping set and screws.

Does the geometry support both roughing and finishing?
The rhombic 55° geometry with a 0.8 mm corner radius offers flexibility for both finishing passes and light roughing, depending on feed and depth of cut.
