SNGA 120408 TH10 — Turning indexable insert (SNGA) by Tungaloy

The SNGA120408 TH10 is an ISO‑standard square indexable insert for turning, designed for external and internal operations where an uncoated, sharp edge supports low cutting forces and improved surface finish.

• ISO standard square insert
• Uncoated carbide TH10 grade
• 0° clearance angle for stable cutting
• 0.8 mm corner radius for fine finish

Optimised cutting performance for stable, efficient turning

The insert combines a TH10 uncoated carbide grade with a sharp geometry that reduces cutting resistance, which in practice leads to low cutting forces and a clean surface on non‑ferrous components. The absence of a coating helps to keep the cutting edge sharp and lowers friction in light‑cutting applications, making the product particularly suitable when machining materials that benefit from a keen edge. This rational design reduces the need for aggressive machine settings while maintaining process reliability and machining economy.

Geometry engineered for consistent surface quality and secure clamping

A 0° relief and a 0.8 mm corner radius give predictable cutting behaviour and a fine surface finish on turned parts. The insert’s square form and cylindrical hole enable secure fastening in compatible holders, so repeatable positioning and stiffness are achieved across multiple re‑indexings. The nominal plate thickness (4.76 mm) and plate size (12 mm) contribute to rigidity in the cutting zone, which is advantageous where dimensional consistency and surface integrity are required.

Seamless integration into ISO turning systems for easy replacement

Classified within the ISO standard series, the insert fits established turning systems when matched to the correct holder or boring bar. Compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness; in practice this means the insert slips into a modular system comprising an insert, a matching external holder or boring bar, a shim/clamping set and replacement screws, allowing straightforward interchangeability and predictable stocking of spare parts.

Material suitability and application guidance for effective use

This sharp universal grade is optimised for non‑ferrous materials and for situations where an uncoated cutting edge delivers the best compromise between low force and surface quality. Typical applications include external and internal turning; the choice of chipbreaker (if required), grade and machining parameters should be matched to the workpiece material and machine stability. The insert is supplied without a chipbreaker, so selection of an appropriate chip control strategy is recommended for continuous turning operations.

FAQ

What materials is this insert suitable for?
The SNGA120408 TH10 insert is designed as a sharp universal grade for machining non‑ferrous materials and applications that benefit from an uncoated cutting edge to reduce cutting forces and improve surface finish.

How does the TH10 grade influence performance?
TH10 is an uncoated carbide grade that prioritises a keen edge and low cutting resistance; the SNGA120408 TH10 therefore delivers efficient cutting and clean surfaces in light to moderate turning operations.

Can this insert be used for internal turning?
Yes, the insert is suitable for both external and internal turning when mounted in an appropriate ISO‑compatible holder or boring bar and when tool overhang and stability are controlled.

What should be considered when selecting a holder for this insert?
Compatibility depends on the insert form, relief angle, tolerance class, fastening method, size and thickness; matching the SNGA120408 geometry to a correctly specified holder ensures secure clamping and repeatable performance.
