VNMG 160404 AH6235 ISO turning insert for external and internal turning — Tungaloy

The VNMG160404-SS AH6235 is an ISO rhombic turning insert engineered for external and internal turning of stainless steel and for interrupted cuts

• ISO rhombic turning insert VNMG 160404 AH6235
• PVD-coated carbide for improved wear resistance
• Designed for stainless steel and interrupted cuts
• 0° clearance angle with 0.4 mm corner radius

Maximise process stability with proven geometry

The ISO rhombic geometry and precise form of the insert provide a repeatable seating in standard holders, contributing to consistent chip formation and stable cutting forces. The grade is a PVD-coated carbide type AH6235, selected for improved toughness compared with standard grades; this reduces the risk of flank and crater wear when machining stainless steel under challenging conditions. The 0.4 mm corner radius and a 0° clearance angle combine to balance edge strength with acceptable cutting forces, which helps to maintain cycle times and part tolerances over longer runs.

Reduce set-up time and boost throughput with standardised components

Because the insert follows ISO conventions, interchangeability with compatible toolholders is straightforward; compatibility depends on the insert form, clearance angle, tolerance class, fastening, size and thickness. The system build comprises the ISO insert, a matching external holder or boring bar, a seating pad or clamp set and replacement screws, allowing rapid reconditioning of tool assemblies. This standardisation supports higher overall productivity by shortening downtime during index changes and simplifying inventory management for workshops and production lines.

Maintain edge integrity in interrupted cuts for fewer rejects

The AH6235 composition is a tougher, PVD-coated carbide grade developed for applications with increased risk of edge breakout, such as interrupted cuts and heavy engagement in stainless steel. Combined with the chipbreaker SS, the insert promotes reliable chip control and reduces the likelihood of sudden chipping, yielding a more consistent surface finish and fewer scrap parts. The result is improved process reliability and tangible cost-effectiveness in serial turning operations where repeatable performance is essential.
