CNMG 190612 AH6235 ISO turning insert — PVD-coated carbide, 1.2 mm radius (Tungaloy)

CNMG 190612 AH6235 is an ISO‑standard rhombic turning insert designed for external and internal turning, offering a tough PVD‑coated carbide grade optimised for stainless steels and interrupted cuts.

• CNMG190612 ISO turning insert, PVD-coated carbide
• AH6235 grade for stainless steel and interrupted cuts
• Double-sided chipbreaker for consistent chip control
• Rhombic 80° geometry with 1.2 mm corner radius

Stable performance where material and interruption challenge productivity

The insert delivers consistent cutting under difficult conditions because of its PVD‑coated carbide substrate and the AH6235 grade, which is formulated for tougher microstructures and improved edge strength. This combination reduces the risk of edge chipping during interrupted cuts and when machining rostfreier Stahl. The coating supports thermal resistance and wear protection, translating into longer tool life and fewer indexings, which improves uptime and lowers process cost per component.

Geometry and holder compatibility that simplify setup and repeatability

The rhombic 80° geometry with a 1.2 mm corner radius provides a reliable compromise between strength and form accuracy. The ISO designation specifies size and shape; compatibility with a holder depends on form, relief angle, tolerance class, fixation method, size and thickness. The insert’s 6.35 mm thickness and cylindrical hole allow secure clamping and stable seating in standard external holders or boring bars. Clear specification reduces trial‑and‑error in fixture selection and helps engineers achieve repeatable part tolerances.

Chip control and application advantages for efficient turning operations

The double‑sided chipbreaker is designed to produce predictable chip shapes across varying cutting conditions, improving evacuation and minimising contact with the workpiece. For external and internal turning tasks, this leads to fewer interruptions from tangled chips or build‑up, especially with stainless steels and applications prone to serrated chips. The insert’s toughness and chip control combine to support higher feeds where process stability allows, delivering enhanced productivity without compromise to surface quality.
