SNMG120404 AH120 indexable turning insert — PVD‑coated carbide, 0.4 mm radius, by Tungaloy

The SNMG120404 AH120 is an ISO‑standard indexable insert designed for general turning, offering a wear‑resistant coating and a geometry matched to common external and internal turning operations.

• PVD‑coated carbide AH120 for wear resistance
• Double‑sided chipbreaker for versatile turning
• 0.4 mm corner radius for accurate finishes
• ISO SNMG 120404, square insert with central hole

Consistent machining performance through optimised coating and edge preparation

The SNMG120404 AH120 insert combines a PVD coating with a tough carbide substrate to provide stable cutting behaviour and extended edge life under typical turning conditions. The coating reduces abrasion and thermal softening during the cut, which in turn supports process reliability and longer tool cycles. For production environments where repeatability and predictable tool life are priorities, the coated carbide grade delivers measurable benefits in reduced tool changes and more consistent workpiece quality.

Predictable chip control and finish thanks to the chipbreaker geometry

A double‑sided chipbreaker is integrated to guide chip formation under a range of feeds and depths of cut; this feature simplifies selection of the insert for both roughing and finishing passes. The chipbreaker helps convert small, fragmenting chips into controlled curls, lowering the risk of chip entanglement and protecting the workpiece surface. With a 0.4 mm corner radius, the geometry balances strength and finish capability, enabling a fine surface on light finishing cuts while retaining adequate edge support for interrupted or unstable cuts.

Compatibility and secure clamping for ISO holder systems

Designed as an ISO standard SNMG insert, the geometry and size align with established holder specifications: square form, central cylindrical hole and a 90° included angle. Compatibility with a given holder depends on form, clearance (relief) angle, tolerance class, fastening method, size and thickness; this makes the insert straightforward to integrate into existing toolholders when the holder matches the ISO SNMG family. The central hole and standard dimensions facilitate secure clamping and repeatable seating, contributing to machine‑side stability and process control.

Practical advantages for workshop logistics and selection

The insert is double‑sided, which effectively doubles the number of available cutting edges per insert compared with single‑edged solutions, improving inventory efficiency. As a PVD‑coated grade optimised for wear and fracture resistance, the AH120 sort is particularly suited where a sharp cutting edge and robust performance are both required. For users less familiar with technical coatings: PVD (physical vapour deposition) forms a thin, adherent layer that enhances hardness and reduces friction at the cutting zone, improving tool life without altering the base carbide’s toughness.

FAQ

Is this insert suitable for both roughing and finishing?
The SNMG120404 AH120 insert, with its double‑sided chipbreaker and 0.4 mm corner radius, is suitable for a range of turning tasks from light finishing to general roughing where a secure edge and chip control are needed.

What material and coating does the insert use?
This Tungaloy indexable turning insert is a PVD‑coated carbide (AH120) grade, designed to combine wear resistance with fracture toughness for stable turning performance.

Can the insert be used in standard SNMG holders?
Yes, the SNMG120404 AH120 follows ISO dimensions for SNMG inserts; compatibility requires a holder matching the insert’s form, relief angle, tolerance class, fastening method, size and thickness.

How many usable edges does each insert provide?
The insert is double‑sided, providing multiple usable cutting edges per insert which improves tool economy and reduces replacement frequency.

What is the recommended corner radius for precision finishing?
The integrated corner radius is 0.4 mm, a compromise between edge strength and the ability to achieve a fine surface finish on finishing passes.
