SNMG120412 AH6225 Tungaloy turning insert — PVD-coated carbide, 1.2 mm corner radius

The SNMG120412 AH6225 Tungaloy indexable insert is designed for external and internal turning, providing a universal grade optimised for stainless steels and variable machining conditions.

• PVD-coated carbide AH6225 for stainless steels
• ISO SNMG form for wide holder compatibility
• 1.2 mm corner radius for robust cutting edge
• Double-sided chipbreaker, square 12 mm plate

Stable edge life with high wear resistance

The AH6225 grade is a PVD-coated carbide formulated to deliver a sharp yet stable cutting edge when machining stainless steels under changing conditions. The coating increases resistance to built-up edge and thermal wear, which translates into longer intervals between indexings and reduced tool-change downtime. The combination of a finely honed cutting geometry and the 1.2 mm corner radius reduces the risk of edge chipping during interrupted cuts, improving component consistency while preserving surface quality. For practical terms, this means fewer interruptions in production and more predictable tool costs per component.

Precise fit and flexible system compatibility

Designed to the ISO SNMG family, the insert matches widely used holders when form, relief angle, tolerance class, fastening method, size and thickness are observed. The square plate measures 12 mm with a 4.76 mm thickness, a cylindrical hole for secure clamping and a 0° relief angle, all of which help ensure repeatable seating and clamping force. The indexable nature and double-sided chipbreaker enable cost-effective utilisation of both cutting edges, and the standardised geometry simplifies inventory and reconditioning decisions. Clear specification of holder compatibility prevents costly mismatches and supports faster setup.

Efficient chip control and application guidance

The integrated chipbreaker geometry supports controlled chip formation on typical turning operations, particularly in stainless steels where stringy chips can impair process reliability. For best results in medium-duty turning, select cutting parameters and chipbreaker variety that suit workpiece stability and material grade; the insert’s universal design provides a practical starting point across a broad range of stainless alloys. The insert is suitable for both external and internal turning; matching the insert with a correctly specified holder, clamping set and replacement screws completes the system for dependable operation and optimised machining output.

FAQ

What materials is this insert suitable for?
The SNMG120412 AH6225 insert is intended primarily for machining stainless steels; the AH6225 PVD-coated carbide provides improved wear resistance and chip control for such alloys.

How does the 1.2 mm corner radius affect machining performance?
The 1.2 mm corner radius on this insert increases edge robustness, reducing chipping risk in medium-duty turning and contributing to consistent surface finish and longer edge life.

Is the insert compatible with standard SNMG holders?
Compatibility depends on matching form, relief angle, tolerance and plate thickness; the SNMG120412 follows ISO SNMG dimensions and seats correctly in holders designed for that standard when the holder parameters match.

Can both sides of the insert be used?
Yes, the insert features a double-sided chipbreaker and is indexable, allowing both cutting edges to be utilised for economical tool usage.

What system components are needed for a complete setup?
A compatible SNMG holder or boring bar, a suitable clamping pad or clamping set, and replacement screws are required to assemble a working cutting system with this insert.
