SPMN 120408 TH10 indexable insert for turning – Tungaloy

A SPMN 120408 TH10 indexable insert engineered for ISO‑standard external and internal turning, offering a square 12 mm form with a 0.8 mm nose radius for controlled finishing.

• ISO‑standard insert, easy holder matching
• Uncoated TH10 carbide for low cutting forces
• Square 12 mm with 0.8 mm nose radius
• 11° clearance angle for stable cutting

Reliable ISO compatibility for straightforward tooling decisions

The insert follows ISO designation, which ensures predictable fitment with matching toolholders and clamping systems; compatibility is determined by form, clearance angle, tolerance class, fastening and thickness. This standardisation simplifies tool selection in production environments and reduces setup time, so holders and underplates can be selected with confidence to maintain a steady machining routine.

Low-cutting-force grade that improves surface finish

Made from uncoated carbide in the TH10 grade, the geometry and material combination is optimised for non‑ferrous metals and operations where a sharp edge reduces cutting forces. Lower forces mean less workpiece distortion and a cleaner surface without aggressive coatings; this supports higher productivity in light finishing and short‑run batch turning where surface quality and minimal burrs are priorities.

Precise geometry for reproducible finishing and process stability

The square 12 mm insert with a 0.8 mm nose radius and 11° clearance delivers consistent tool contact and predictable chip flow even without a dedicated chipbreaker. A defined included angle of 90° supports straightforward profile turning and facing, while the nominal thickness of 4.76 mm contributes to secure clamping and edge stability. These geometric parameters reduce vibration risk and help maintain dimensional accuracy across repeated indexings.

FAQ

What workpiece materials is this insert suitable for?
The TH10 uncoated carbide grade is intended primarily for non‑ferrous metals and applications where a sharp edge and low cutting forces produce a clean surface.

Can this indexable insert be used for both external and internal turning?
Yes, the ISO‑format square insert is suitable for both external and internal turning operations when paired with the correct holder and mounting hardware.

What does the 0.8 mm nose radius mean for finishing?
A 0.8 mm nose radius provides a balance between fine surface finish and tool strength; it helps achieve smooth contours without excessive tool deflection in light to moderate cuts.

Is a chipbreaker included with this insert?
This insert is supplied without a chipbreaker, which is typical for sharp uncoated grades aimed at low cutting forces and clean finishes on softer or non‑ferrous materials.

Which holders are compatible with the insert?
Compatibility depends on the holder's form, clearance angle, tolerance class, fastening and thickness; matching an ISO‑compatible holder designed for the SPMN form ensures secure clamping and correct cutting geometry.
