SPMN 120304 UX30 turning insert by Tungaloy

SPMN120304 UX30 is an ISO‑standard square turning insert engineered for external and internal turning, offering a sharp uncoated carbide grade that prioritises low cutting forces and controlled chip formation.

• ISO‑standard insert for broad compatibility
• Sharp UX30 carbide for low cutting forces
• 0.4 mm corner radius for versatile turning
• Square 12 mm format, 3.18 mm plate thickness

Stable compatibility for ISO tooling systems

The ISO‑standard geometry of this indexable insert guarantees straightforward matching with common external holders and boring bars; compatibility is determined by form, relief angle 11°, tolerance class, clamping method, size and thickness. For production planners and toolroom managers, the standardised interface reduces setup complexity and inventory variety, enabling faster tool changes and fewer machine downtimes. The square format and repeatable locating surfaces support consistent positioning and predictable process behaviour.

Controlled cutting performance with the UX30 grade

The uncoated carbide grade UX30 features a sharp cutting edge designed for operations where low cutting forces and good chip formation are priorities. In interrupted cuts or thin-walled components, a sharper geometry can reduce cutting force peaks and help preserve workpiece integrity. The combination of the 0.4 mm corner radius and the sharp edge offers a balanced compromise between edge strength and finish quality, making this insert suitable for general turning where stable material removal and surface integrity matter.

Practical guidance for holder selection and setup

Selection of the mating holder and the correct chip control equipment remains essential: choose a compatible ISO holder or boring bar that matches the insert’s form and thickness (3.18 mm) and that provides secure clamping. Where chip control is critical, pair the insert with an appropriate chipbreaker or adapt cutting parameters and coolant strategy to the workpiece. For internal turning, ensure adequate tool overhang and rigidity; for external turning, prioritise stable workholding and minimal projection to make best use of the insert’s low cutting‑force behaviour.

Operational value: tool life, repeatability and process security

Using a standardised indexable geometry reduces the need for custom tooling and supports consistent tool indexing, which in turn enhances repeatable results and predictable tool life. The uncoated UX30 grade is intended for applications that favour low force cutting and reliable chip flow rather than aggressive high‑speed machining; this makes it a cost‑effective choice for many routine turning tasks. The square 12 mm format gives multiple index positions per insert, contributing to economical use over successive tool changes and helping to maintain steady production throughput.

FAQ

What holders are compatible with this insert?
The SPMN120304 UX30 turning insert is compatible with ISO‑standard external holders and boring bars where the insert form, relief angle 11°, tolerance class, clamping and 3.18 mm thickness match the holder specifications.

Is the UX30 grade suitable for stainless workpieces?
The UX30 uncoated carbide grade is designed for operations prioritising low cutting forces and good chip formation; suitability for specific stainless steels depends on the alloy and cutting conditions, so matching chip control and parameters is recommended.

How many index positions are available on the insert?
As a square 12 mm insert, the SPMN120304 offers multiple index positions typical for four‑sided inserts, enabling economical re‑indexing to extend service life and maintain consistent geometry.

Can this insert be used for finishing passes?
Yes — with the 0.4 mm corner radius and sharp edge, the insert can deliver acceptable surface quality for many finishing operations when run with appropriate feeds and speeds and with adequate rigidity.

What does 'no chipbreaker' mean for process planning?
The supplied insert is delivered without an integrated chipbreaker; process stability then relies on cutting parameters, coolant and holder geometry, so a suitable chip management strategy should be defined for the specific material and operation.
