SNMG 120404 AH6235 ISO turning insert for Drehen — Tungaloy

SNMG120404 AH6235 Tungaloy insert designed for ISO‑standard external and internal turning with enhanced resistance to chipping and interrupted cuts

• ISO SNMG120404 geometry
• PVD-coated AH6235 grade
• Double-sided chipbreaker
• 0.4 mm corner radius

Increased productivity through stable cutting performance

The PVD-coated carbide grade AH6235 delivers a balance of toughness and wear resistance that is particularly beneficial for machining stainless steels and other difficult‑to‑cut alloys. The coating promotes improved edge retention under variable loads, which reduces the frequency of index changes and supports a steadier production rhythm. Where interruptions or heavy feed variations occur, the tougher substrate and coating combination helps maintain cutting integrity and avoid premature edge failure, improving overall throughput.

Predictable chip control and surface quality

A double-sided chipbreaker combined with the SNMG geometry offers consistent chip formation and evacuation in both external and internal turning. The 0.4 mm corner radius supports robust edge strength while producing acceptable surface finishes in semi‑finishing and finishing passes. Operators unfamiliar with the terminology: the chipbreaker is the small groove on the insert face that shapes chips to prevent entanglement and aid coolant flow — this feature directly contributes to safer, cleaner machining and fewer interruptions on the shop floor.

Simple compatibility and secure clamping

Compatibility with existing toolholders depends on form, relief angle, tolerance class, fastening method, size and thickness. The square SNMG120404 shape and 4.76 mm plate thickness make the insert suitable for a wide range of standard ISO external holders and boring bars that accept SNMG‑type cartridges. The insert comes with a cylindrical hole for positive indexing and secure clamping, helping to ensure repeatable seating and stable cutting across multiple tool changes.

Application guidance for interrupted cuts and tough alloys

For applications involving abrupt interruptions or a risk of edge breakout, the AH6235 grade's toughness reduces chipping and extends usable life, particularly when machining rostfreie Stähle and other alloys prone to work hardening. Select cutting speeds and feeds that favour moderate cutting temperatures to exploit the grade's balance between wear resistance and fracture toughness; this approach minimises thermal shock and supports consistent performance across batch runs.

FAQ

What materials is this insert suited for?
The SNMG120404 AH6235 insert is formulated for stainless steels and other tougher alloys where a tougher, PVD‑coated carbide improves resistance to chipping.

Can the insert be used for interrupted cuts?
Yes, the AH6235 grade and the robust corner radius are chosen to resist breakout and maintain edge integrity during interrupted machining.

Is the insert reversible and double‑sided?
The insert features a double‑sided chipbreaker and is indexable to use multiple cutting edges before replacement, consistent with SNMG geometry.

How is compatibility with holders determined?
Compatibility depends on the insert form, relief angle, tolerance class, fastening, size and thickness; use holders specified for SNMG120404 geometry and the listed plate thickness.

What advantage does the PVD coating provide?
The PVD coating enhances wear resistance and edge life while maintaining toughness, helping to deliver consistent results in production environments.
