SPMN 120408 UX30 Tungaloy turning insert — square ISO insert, 11° clearance

A SPMN 120408 UX30 turning insert for external and internal turning, engineered for low cutting forces and consistent chip formation in general turning applications.

• Square ISO insert for stable seating
• Sharp edge grade UX30 for low cutting forces
• Uncoated carbide for predictable chip formation
• 11° clearance angle supporting finish turning

Predictable chip behaviour for efficient turning

The UX30 grade is an uncoated carbide specification developed for a sharp cutting edge, promoting controlled chip formation and lower cutting forces. This results in steadier cutting conditions and reduced tendency for vibration during both light finishing and more demanding roughing passes. As an ISO-compliant insert, it supports repeatable results across comparable toolholders, helping to maintain consistent surface quality and tool life.

Geometry tailored to reduce cutting effort and improve finish

A square insert profile combined with a corner radius 0.8 mm and an 11° clearance provides a balance between edge strength and low force cutting. The modest corner radius supports improved surface finish while still offering sufficient edge robustness for interrupted cuts. The geometry reduces radial cutting forces, which benefits machine stability and can enable higher feed rates with the same level of process control.

ISO-system compatibility for rapid integration into tool setups

Designed as an ISO-standard turning insert, compatibility with a holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The system concept typically includes the insert, a matching external holder or boring bar, a shim/clamp set and replacement screws — a modular approach that simplifies logistics and spare-part management. Clear ISO identification supports quick substitution and minimises machine downtime during tool changes.

Practical selection advice and task alignment

With no integrated chipbreaker, this insert is best employed where low cutting forces and predictable chips are priorities; choose the appropriate chipbreaker and grade when processing different materials or when heavy chip control is required. The specification supports both external and internal turning tasks; pairing the insert with a suitable holder and cutting parameters ensures repeatable machining and reliable edge performance throughout production batches.

FAQ

What tasks is this insert suitable for?

The SPMN 120408 UX30 turning insert is intended for general external and internal turning where low cutting forces and predictable chip formation are required.

Is the insert coated and which grade does it use?

This insert is made of uncoated carbide and specified in grade UX30, which emphasises a sharp cutting edge and stable chip behaviour.

What are the key dimensions to check before fitting?

Check the 12 mm size, 4.76 mm thickness, 0.8 mm corner radius and 11° clearance angle to ensure correct fitment in the chosen holder for the SPMN 120408 UX30 insert.

Does the insert include a chipbreaker?

No; the SPMN 120408 UX30 insert is supplied without a chipbreaker, so chip control should be managed by selecting a matching chipbreaker grade or optimising cutting parameters as required.

How is compatibility with toolholders ensured?

Compatibility is determined by insert form, free angle, tolerance class, fastening method, size and thickness; the insert integrates into ISO-standard holder systems when these parameters match.
