DNMG150412 AH6235 ISO turning insert — PVD-coated carbide for stainless steel turning, Tungaloy

DNMG150412 AH6235 is an ISO rhombic turning insert engineered for demanding external and internal turning of stainless steels and for operations prone to interruption or edge breakout.

• PVD-coated carbide grade AH6235
• Optimised for stainless steels & interrupted cuts
• ISO DNMG 150412 rhombic geometry
• Cylindrical hole, double-sided chipbreaker

Durable edge life for challenging stainless steel work

The AH6235 grade is a PVD-coated carbide developed to combine toughness with thermal resistance, which extends tool life in operations with variable cutting forces. In practice, this means enhanced resistance to chipping during interrupted cuts and improved edge stability when machining work-hardened or austenitic stainless steels. The coating reduces friction and heat buildup at the cutting zone, supporting consistent surface finish over longer tool cycles and fewer indexings.

Precise ISO geometry for consistent mounting and repeatability

The DNMG150412 designation corresponds to a rhombic insert with a defined lead angle and stable seating dimensions; the plate has a 15 mm size, 1.2 mm corner radius and a thickness of 4.76 mm, plus a cylindrical hole for secure clamping. The specified 0° clearance angle and a 55° lead angle yield predictable chip flow and contact conditions. Because compatibility depends on form, clearance, tolerance class, fastening, size and thickness, the ISO standardisation ensures reliable interchangeability with matching holders and clamping sets.

Improved chip control and application-specific grade selection

The insert features a double-sided chipbreaker that supports controlled chip formation across a range of feeds and depths, reducing the risk of chip entanglement and enhancing process stability. Select the chipbreaker and the AH6235 grade when facing stainless steels, discontinuous cuts or operations with a higher risk of edge breakout. The combination of grade and chip control enables economical machining by lowering scrap risk and maintaining consistent machining parameters over multiple indexings.

Practical integration in tool systems and workshop routines

As part of an ISO insert system, the component is used with a compatible external holder or boring bar, plus a support shim or clamp set and replacement screws as required. The PVD-coated carbide construction simplifies handling: indexable, double-sided use halves tooling cost per edge compared with single-use tips. For shops seeking predictable performance in stainless steel turning, the combination of ISO conformity, robust chip control and a tough coated grade supports higher productivity and repeatable surface quality with minimal process tuning.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The DNMG150412 AH6235 Tungaloy insert is designed specifically for stainless steels and for operations with a risk of interruption, offering improved edge stability and wear resistance.

Can the insert be indexed to use multiple cutting edges?
Yes. The rhombic, double-sided design allows indexing to a fresh edge; the double-sided chipbreaker supports repeatable chip control across indexings.

Which holders are compatible with this insert?
Compatibility requires matching the ISO DNMG form, size, thickness and hole/clamping style; use holders specified for DNMG 150412 inserts and ensure correct shim/clamp and screw selection.

How does the AH6235 grade help with interrupted cuts?
The AH6235 grade combines a tougher substrate and a PVD coating to resist chipping and reduce thermal softening, which improves durability in interrupted cutting conditions.

Is this insert suitable for internal turning as well as external turning?
Yes. The geometry and chip control make it appropriate for both external and internal turning operations when the holder and reach are compatible.
