SNMA 120412 TH10 — SNMA ISO 120412 indexable turning insert for external and internal turning, Tungaloy

The SNMA120412 TH10 is a square ISO‑standard indexable turning insert designed for external and internal turning, offering a 90° form angle and a 1.2 mm nose radius for controlled finishing.

• ISO-standard square insert (90° form angle)
• Uncoated carbide grade TH10 for low cutting forces
• 1.2 mm nose radius for controlled finish
• Cylindrical hole for secure clamping

Consistent machining performance for ISO‑compliant turning

The insert is manufactured to the ISO designation 120412, which ensures predictable geometry and fit when paired with matching holders. Compatibility is influenced by the insert form, 0° free (rake) angle, tolerance class, fastening method, nominal size and thickness; these parameters reduce setup time and risk of misfits. For production runs this translates into repeatable cutting behaviour and lower scrap rates, as the standardised geometry supports toolpath planning and holder interchangeability. The ISO conformity also simplifies inventory management across different machines.

Efficient cutting and improved surface quality with TH10

The uncoated carbide TH10 grade is a sharp, universal specification optimised for non‑ferrous materials and applications where a bare cutting edge helps maintain low cutting forces and a clean surface finish. An uncoated edge minimises thermal insulation at the cutting zone, which can be advantageous for materials sensitive to built‑up edge. Where low machining forces and good part appearance are priorities, this grade often outperforms more highly coated variants. Note that the insert is supplied without a chipbreaker, so choosing a suitable chip control geometry for the workpiece and machining stability is essential.

Robust clamping and practical system configuration

The square SNMA form with a 90° form angle and a 1.2 mm nose radius offers versatility for both roughing and finishing passes when the process parameters are matched to machine and setup stiffness. The plate thickness of 4.76 mm and the cylindrical hole support secure clamping; a correct shim and clamp set with the appropriate screws completes the system. System assembly normally comprises the ISO indexable insert, a compatible external holder or boring bar, an underlay/shim or clamping set and replacement screws. Selecting the right grade, chipbreaker geometry and holder stability remains decisive for surface integrity and tool life.

FAQ

Which materials is this insert best suited for?
The SNMA120412 TH10 insert is specified for non‑ferrous materials and similar applications where an uncoated carbide edge supports low cutting forces and clean surfaces.

Is the TH10 grade coated or uncoated?
TH10 is an uncoated carbide grade; the bare cutting edge is chosen to reduce cutting forces and assist in achieving good surface finish for appropriate materials.

What holder compatibility should be checked before ordering?
Compatibility requires matching the insert form, 0° free angle, tolerance class, fastening method, size and thickness to the holder; Metav Werkzeuge can advise on the correct external holder or boring bar.

Does the insert include a chipbreaker?
This configuration is supplied without a chipbreaker; chip control must be addressed via process parameters or a different insert geometry if required.

How does the 1.2 mm nose radius affect finish and tool life?
A 1.2 mm nose radius balances improved surface finish with acceptable cutting forces; larger radii can enhance tool life at the expense of higher radial cutting load.
