Take advantage of a compact, ISO‑standard indexable insert that combines a sharp UX30 cutting grade, a corner radius of 1.2 mm and a 90° square geometry for stable external and internal turning operations; order directly via Metav Werkzeuge or consult the team for application-specific advice.

SPMN190412 UX30 Tungaloy indexable insert for turning

SPMN190412 is an ISO‑standard square indexable insert designed for external and internal turning with a sharp cutting edge and UX30 grade.

• ISO square insert for external and internal turning
• Sharp-edge UX30 grade for low cutting forces
• Corner radius 1.2 mm for controlled chip formation
• 11° relief and 90° shape for stable engagement

Lower cutting forces through a sharp UX30 grade

The combination of the UX30 grade and an uncoated carbide substrate reduces cutting forces during light to moderate turning, which benefits both tool life and machine load. The grade is formulated for operations where a sharp edge and predictable chip formation are essential; this results in smoother cutting behaviour and reduced power draw in many lathe applications. The design is particularly suitable for jobs where minimal burr and consistent surface finish are required, helping to maintain steady cycle times in production.

Geometry engineered for secure engagement and compatibility

A 90° square plate with 11° relief and a corner radius of 1.2 mm provides a robust contact area and predictable strength at the cutting edge. The ISO conformity of the insert simplifies selection of matching toolholders: compatibility depends on form, relief angle, tolerance class, clamping style, size and thickness, all of which are standardised for reliable interchangeability. This geometry supports repeatable seating and clamping, which reduces setup variation and contributes to repeatable part quality.

Practical advantages in workshop workflows

The insert’s square shape and ISO designation make stock management and tool rotation straightforward: four indexing positions extend useful life before replacement. The relatively modest corner radius offers a balance between edge strength and the ability to produce fine contours on shafts and bores. Packaged as a component of the standard ISO turning system, the item integrates with conventional external holders, boring bars, clamping sets and replacement screws, enabling rapid changeovers and predictable spare‑part logistics.

Material adaptability and recommended use cases

Designed primarily for turning, the insert performs well where low cutting forces and efficient chip control are priorities. The uncoated carbide substrate of the SPMN190412 suits a wide range of steels and materials typically encountered in general turning, offering good edge retention without the characteristics of PVD/CVD coatings. For operations requiring higher thermal or wear resistance, consider alternative coated grades; for tasks that prioritise a very sharp edge and consistent chip formation, UX30 provides a practical balance.

FAQ

Which operations are best suited to this insert?
The SPMN190412 UX30 insert is intended for external and internal turning where a sharp edge and consistent chip formation are required; it performs well in general turning tasks.

Is the insert compatible with standard ISO holders?
Yes, the ISO‑standard form of the SPMN190412 ensures compatibility with holders that match the insert’s form, relief angle, tolerance class, clamping method, size and thickness.

What materials is this grade suitable for?
The UX30 uncoated carbide substrate is suitable for a broad range of steels and common turning materials where low cutting forces and good chip control are prioritised.

How does the corner radius affect finish and strength?
A 1.2 mm corner radius offers a compromise between edge strength and surface finish, providing reliable performance on shafts and bores without excessive cutting forces.

Are there chipbreakers or holes on this insert?
This particular ISO insert is supplied without a chipbreaker and without a hole, offering a plain cutting geometry for applications prioritising a sharp edge.
