SNMG 120412 AH6225 Indexable Insert for Turning — Tungaloy

A SNMG120412 AH6225 indexable insert designed for ISO-compliant external and internal turning, optimised for machining rostfreier Stahl under varying mid-range cutting conditions

• PVD-coated carbide grade AH6225
• Universal grade for rostfreier Stahl
• SNMG120412, 12 mm square insert
• Double-sided chipbreaker, cylindrical hole

Sharp, stable cutting edge for consistent machining

The combination of PVD-coated carbide and the AH6225 grade delivers a sharp, stable cutting edge that performs reliably in interrupted cuts and changing conditions. As a universal grade engineered specifically for rostfreier Stahl, the insert balances edge sharpness and wear resistance to reduce flank wear and maintain surface finish over longer tool life. The PVD layer enhances adhesion resistance and thermal stability, helping to sustain cutting performance when feeds and speeds vary during production runs. This behaviour supports predictable cycle times and fewer tool changes, directly contributing to improved throughput.

Secure fit and repeatable clamping minimise set-up variability

The ISO geometry of SNMG120412 ensures predictable seating in compatible holders; critical dimensions such as 12 mm inscribed circle and 4.76 mm thickness provide a consistent reference for clamping. A 1.2 mm corner radius and 0° clearance angle offer a compromise between edge strength and finishing capability, while the cylindrical hole and square form guarantee reliable location and repeatability. Correct matching of holder form, clearance angle, tolerance class, fastening and plate thickness reduces vibration and chatter, which in turn stabilises cutting forces and improves dimensional consistency across batches.

Productivity gains through adaptable chip control and system approach

The double-sided chipbreaker supports effective chip control for a range of turning operations and aids safe evacuation in both external and internal applications. Used as part of a system — insert, compatible external holder or boring bar, underlay/clamping set and correct fastening hardware — the component contributes to enhanced productivity and extended tool life when cutting parameters are optimised. For process reliability, select the chipbreaker variant and cutting data according to workpiece rigidity and machining strategy; small adjustments to depths of cut and coolant usage can significantly prolong edge life while maintaining surface quality.
