VCMT 160404 AH6235 — ISO rhombic turning insert (turning) by Tungaloy

The VCMT 160404 AH6235 is an ISO-format rhombic turning insert designed for external and internal turning, offering robust performance for interrupted cuts and demanding stainless-steel applications.

• PVD-coated cemented carbide for durability
• Optimised PS chipbreaker for reliable chip control
• Rhombic shape 16 mm, 0.4 mm nose radius
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for stainless applications

This insert delivers repeatable results through a combination of a PVD-coated surface and a tough cemented carbide substrate. The AH6235 grade is formulated to resist adhesive wear and handle the thermal and work-hardening tendencies of stainless steels, which reduces edge breakdown during interrupted cuts. By choosing a dedicated grade and the PS chipbreaker, the tool achieves stable chip formation and fewer built-up edges, translating into longer effective tool life and fewer interruptions on the shop floor.

Geometry tuned for accuracy and production efficiency

The rhombic ISO 160404 form, with a 0.4 mm nose radius and a 7° clearance angle, balances cutting strength and profile fidelity. The small nose radius supports fine surface finishes while maintaining sufficient edge robustness for higher feed rates where profile control matters. The PS chipbreaker is tailored to evacuate chips efficiently in medium to heavy interrupted passes; this reduces cycle times and the need for reactive process adjustments. Compatibility with common ISO holders simplifies tool changeover and keeps spindle downtime to a minimum.

Integration into stable machining processes

Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; the insert fits standard external holders or boring bars when matched correctly. The central hole — supplied as a cylindrical bore with a one-sided countersink (40°–60°) — ensures secure clamping and precise seating. For shops aiming to standardise inserts, the combination of PVD coating, a robust grade and the PS chipbreaker supports predictable tool life and reduced scrap rates in production lines.

FAQ

What materials is this insert suitable for?
The VCMT 160404 AH6235 is designed primarily for stainless steels and performs well in interrupted cutting conditions where increased breakout risk exists.

How does the PS chipbreaker affect machining?
The PS chipbreaker on the VCMT 160404 AH6235 promotes controlled chip formation and evacuation, improving surface finish and reducing the likelihood of built-up edge in medium to heavy interrupted cuts.

Which holders are compatible with this ISO insert?
Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; the insert matches standard ISO holders and external turning bars when these parameters align with ISO 160404 specifications.

What is the significance of the 0.4 mm nose radius?
A 0.4 mm nose radius balances profile definition and edge strength, enabling finer surface finishes without sacrificing robustness during higher feed operations.

Is the insert supplied with a countersunk hole?
Yes — the insert features a cylindrical centre hole with a one-sided countersink (40°–60°) to ensure secure clamping and precise seating.
