CNMG 090408 AH6235 indexable insert for turning — Tungaloy

CNMG090408 AH6235 indexable insert for ISO-format external and internal turning, designed for stainless steels and interrupted cuts

• ISO rhombic geometry CNMG 09 format
• AH6235 PVD-coated carbide grade
• 0° relief for robust engagement
• Double-sided chipbreaker with cylindrical hole

Greater resistance to notch and chipping for stainless turning

The CNMG090408 AH6235 indexable insert combines a PVD coating with a tougher carbide substrate to resist edge breakdown during the machining of stainless steels and other demanding alloys. The coating reduces built-up edge and improves wear behaviour, while the tougher substrate increases fracture resistance in interrupted cuts. This results in longer edge life and fewer unscheduled insert changes, supporting stable production and predictable maintenance intervals.

Reliable chip control and secure clamping for consistent results

A double-sided chipbreaker on a rhombic ISO geometry delivers consistent chip formation and evacuation in medium to heavy turning operations. The insert’s cylindrical hole and standard ISO dimensions ensure repeatable clamping with most ISO holders; compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness. The 0° relief angle provides robust engagement at the cutting edge, improving workpiece finish and reducing vibration risks in less rigid setups.

Pragmatic benefits for workshop productivity and process stability

Selecting this grade and geometry translates into measurable production benefits: fewer tool changes, improved surface quality and better handling of interrupted cuts common in stainless-steel components. The double-sided design effectively doubles the available cutting edges per indexable insert, offering economical edge utilisation. For operations focused on repeatability and uptime, this insert supports higher first-pass yields and reduced rework, making it a practical choice for series turning and repair work.

FAQ

Which holder types are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance and fastening; the CNMG090408 AH6235 indexable insert fits ISO-compatible CNMG holders with matching size and clamping geometry

Is this insert suitable for continuous turning of stainless steels?
Yes, the AH6235 grade and PVD coating are optimised for stainless steels and deliver improved wear resistance for continuous as well as interrupted turning operations

How many effective cutting edges does the indexable insert offer?
The double-sided design provides two usable cutting edges per side when indexed according to the ISO geometry, extending effective edge life and reducing tooling costs

What does the 0° relief angle mean in practice?
A 0° relief angle gives a robust cutting engagement with reduced likelihood of edge chipping under heavy load; it supports stability in less rigid setups and during interrupted cuts
