SPMN 120312 TH10 turning insert (SPMN) — Tungaloy

SPMN 120312 TH10 is an ISO-format indexable turning insert designed for external and internal turning applications, providing a sharp uncoated cutting edge for low-force machining of non-ferrous materials.

• ISO-format indexable turning insert
• Uncoated carbide grade TH10
• 1.2 mm corner radius for stable cuts
• Square 12 mm size, 11° clearance angle

Precision and surface quality with low cutting forces

The uncoated carbide grade TH10 delivers a consistently sharp cutting edge that supports low cutting forces and clean part surfaces in non-ferrous machining. An uncoated grade reduces built-up edge tendency when machining softer alloys, which helps to maintain dimensional accuracy over longer cutting lengths. The result is stable, repeatable performance with fewer interruptions for finishing passes, improving throughput and lowering overall machining costs.

ISO compatibility for straightforward toolset integration

Supplied in an ISO format, the insert is compatible with a wide range of indexable turning holders, provided the holder matches by shape, clearance angle, tolerance class, fastening style, size and thickness. The square form with a 12 mm side, 3.18 mm thickness and 11° clearance angle simplifies tool selection: holders designed for ISO SPMN plates accept this geometry without modification. As a consequence, setup times are reduced and repeatability is improved because the system relies on standardised interfaces rather than bespoke adapters.

Robust edge geometry and practical system considerations

The 1.2 mm corner radius supplies additional edge strength for moderate depth cuts and helps to avoid premature edge chipping, while the plate’s lack of a central hole and absence of a chipbreaker mean the insert is intended for holders that clamp the plate securely by shape and screw. Typical system composition comprises the ISO insert, a compatible external holder or boring bar, a shim/clamping set and replacement screws. This straightforward assembly supports consistent clamping force, reliable repeatability and easier stock keeping of consumables.

FAQ

What materials is this insert best suited for? The answer: The TH10 uncoated carbide grade on the SPMN 120312 TH10 insert is optimised for non‑ferrous materials and applications where a sharp, uncoated edge supports low cutting forces and clean surface finish.

How is the insert secured in the holder given it has no hole? The insert is clamped by form and screw in a compatible ISO holder; the system relies on the square plate geometry, clamp or shim and screw arrangement for secure fixing.

Can this insert be used for both external and internal turning? Yes. The SPMN 120312 TH10 format is suitable for external and internal turning where the holder and clamping set match the ISO plate geometry and thickness.

What effect does the 1.2 mm corner radius have on cutting? A 1.2 mm corner radius increases edge strength and reduces chipping risk during moderate depth cuts, improving stability and part quality.

Is there a chipbreaker on this plate? No, this insert is supplied without a chipbreaker; chip control must be achieved via cutting parameters, workpiece material or the choice of a holder with chip control features.
