SPMN120312 UX30 indexable turning insert — Tungaloy (for turning)

SPMN120312 UX30 is an ISO-standard indexable turning insert designed for external and internal turning; the uncoated cemented carbide grade delivers a sharp cutting edge for low cutting forces and reliable chip formation

• SPMN120312 ISO indexable turning insert UX30
• Sharp cutting edge for low cutting forces
• 11° relief angle for stable turning
• 1.2 mm nose radius for fine profile control

Consistent cutting performance for productive turning

The ISO-standard geometry ensures predictable behaviour in a wide range of turning set-ups, which supports process stability and repeatability on the shop floor. The insert is manufactured from cemented carbide and graded UX30 for a sharp edge that reduces cutting force, meaning less power draw and reduced vibration in many operations. When paired with a suitably rigid holder the design helps maintain dimensional accuracy over longer runs, so fewer in-process adjustments are required and cycle times can be optimised.

Low cutting forces and reliable chip formation

The uncoated UX30 grade is specified for operations where a sharp edge and good chip control are priorities; the cutting edge geometry promotes short, manageable chips under typical turning conditions. Lower instantaneous cutting forces reduce tool deflection and can improve surface finish without resorting to coatings that may blunt the edge in certain materials. The result is a balance between machinability and tool life that benefits small-batch and serial production alike, especially when machining steels and less demanding alloys.

Designed for straightforward system integration

Compatibility with a clamping system depends on insert form, relief angle, tolerance class, fastening method, size and thickness — factors considered in the ISO designation. The recommended system build comprises the ISO indexable insert, a matching external holder or boring bar, a shim/clamping set and spare screws to secure the insert. The insert’s square shape and 90° cutting angle permit multiple indexing positions, extending usable life before regrinding or replacement is required.

Suitable applications and practical handling advice

This insert is suitable for general turning tasks where a sharp edge is advantageous and no chipbreaker is required; select the UX30 grade when low cutting forces and consistent chip formation are the priority. With a 1.2 mm nose radius and 11° relief angle, it is well suited to finishing and medium light roughing passes, producing clean profiles and edges. For best results, ensure correct seat contact and torque on the clamping screw, verify holder rigidity, and match cutting parameters to material and machine capability to maximise tool life.

FAQ

What materials is this insert suitable for?
The SPMN120312 UX30 indexable turning insert is optimised for common steels and general-purpose turning where a sharp edge and good chip formation are required; evaluate cutting data against the specific workpiece material.

Does the insert include a chipbreaker?
No, the SPMN120312 UX30 insert is supplied without a chipbreaker and is intended for operations where the geometry and grade provide the required chip control.

How is compatibility with a toolholder ensured?
Compatibility is determined by the ISO form, relief angle, tolerance class, fastening method, size and thickness; check holder specifications against the SPMN120312 dimensions before assembly.

What cutting tasks is the UX30 grade best for?
UX30 is chosen where low cutting forces and a sharp cutting edge are priorities, such as finishing and light to medium turning passes that require consistent chip control.

Can the insert be indexed multiple times?
Yes, the square shape and 90° cutting angle permit multiple indexing positions to extend usable life before replacement.
