CNMG120412 AH6235 CNMG ISO turning insert for turning — Tungaloy

A CNMG120412 AH6235 indexable turning insert engineered for external and internal turning, optimised for stainless steels and interrupted cuts.

• PVD-coated carbide grade AH6235
• Tailored for stainless steels and interrupted cuts
• Double-sided chipbreaker for stable machining
• 80° rhombic form with 1.2 mm nose radius

Consistent cutting performance for demanding materials

The ISO-designated insert delivers consistent results thanks to its PVD-coated carbide composition and a grade developed for tougher workpiece materials. The PVD layer increases wear resistance while the substrate provides toughness to resist chipping in interrupted cuts. This combination supports higher process stability when machining stainless steels, where work-hardening and built-up edge are common concerns. The result is fewer unexpected tool changes and more predictable cycle times, contributing directly to improved productivity on the shop floor.

Predictable fit and repeatable machining accuracy

Compatibility with toolholders is governed by the insert’s form, clearance angle, tolerance class, fastening style, size and thickness. The rhombic 80° geometry and 0° clearance angle allow secure clamping in standard ISO turning holders; the insert’s cylindrical hole facilitates correct seating and positive location. Clear reference to the ISO code and dimensions reduces setup time and helps to ensure repeatable cutting conditions. For operations that require narrow process windows, this predictable fit supports enhanced surface finish and more reliable tool life.

Economy through double-sided design and stable chip control

The insert’s double-sided chipbreaker and symmetric geometry enable economical use of the cutting edges and quick indexation when wear occurs. The 1.2 mm nose radius balances form retention with cutting forces, making it suitable for a range of turning tasks without sacrificing dimensional control. Because the grade AH6235 is formulated for increased resistance to edge breakouts, downtime for insert changes is reduced and scrap rates fall. In short, this insert is designed to combine operational efficiency with robust performance in challenging turning applications.
