SNMG120402 NS9530 — SNMG indexable turning insert for turning, Tungaloy

SNMG120402 NS9530 is an ISO-form indexable insert engineered for finishing steel components, offering a sharp cutting edge and stable surface results.

• Precision finishing for steel parts
• Sharp cutting edge, low cutting forces
• Double-sided insert for longer tool life
• ISO 120402 form with cylindrical hole

Superior surface quality and reduced cutting forces

The uncoated cermet grade NS9530 is developed as a finishing grade for steel, delivering a sharp cutting edge that lowers cutting forces and improves surface integrity. For continuous cuts and small depths of cut, the material combination provides consistent chip formation and minimised vibration, translating into a measurable improvement in final part quality. The insert’s geometry and edge preparation are optimised to produce fine surface finishes while keeping thermal and mechanical loading on the tool low, which benefits cycle-time consistency in serial turning operations.

Reliable fit and system compatibility for fast changeovers

Designed to ISO dimensions, the insert ensures predictable compatibility with holders and boring bars when form, clearance angle, tolerance class, fastening method, size and thickness are matched. The square plate format with a cylindrical locating hole enables stable seating and straightforward indexing. As a double-sided insert with a corner radius of 0.2 mm and a plate thickness of 4.76 mm, it offers repeatable clamping and simple replacement, reducing machine downtime and simplifying tool inventory management across multiple machines and setups.

Economic operation through indexability and consistent chip control

The insert’s double-sided design effectively doubles usable cutting edges, contributing to lower cost per edge and longer intervals between tool changes. The integrated double-sided chipbreaker supports steady chip evacuation during finishing passes, which aids process stability and reduces the need for rework. Where production demands constant tolerances and repeatable surface quality, this solution supports efficient throughput while maintaining high-quality finishes, making it well suited for precision component manufacturers working with steel.

Practical handling and application notes for machinists

The ISO mounting and standardised form mean that the insert is usable in common turning toolholders and on many boring bars, provided the holder matches the insert’s dimensions and tolerance class. The 0° clearance angle and 90° orientation are suitable for typical external and internal turning operations focused on fine finishing. For system assembly, include a matching external holder or boring bar, an underlay/clamp set and spare fastening screws; these items complete a reliable tooling system and help ensure consistent seating and performance on the machine.

FAQ

What machining tasks is this insert best suited for?
The SNMG120402 NS9530 insert is intended primarily for finishing operations in steel, where a sharp edge and low cutting forces are required to achieve high surface quality.

Is the insert reversible and how does that affect cost-efficiency?
The insert is double-sided, allowing indexing of multiple cutting edges; this increases usable life per insert and reduces cost per edge for production runs.

Which toolholders are compatible with the ISO SNMG120402 form?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and thickness; the SNMG120402 form matches standard ISO square insert toolholders and appropriate boring bars.

Can this insert handle interrupted cuts or only continuous finishing passes?
The NS9530 grade is optimised for continuous finishing and small depths of cut; for heavy interrupted cuts a different grade or geometry should be considered.

What are the locating and clamping features of the insert?
The insert has a cylindrical locating hole and is secured using standard clamp and screw systems; stable seating ensures repeatable performance and simple replacement.
