SPGN120408 TH10 indexable turning insert for turning — Tungaloy

The SPGN120408 TH10 is an ISO-standard indexable turning insert engineered for both external and internal turning, offering a sharp universal grade for non-ferrous materials and applications requiring low cutting forces.

• ISO-standard square insert 90° geometry
• Uncoated cemented carbide, TH10 universal grade
• 0.8 mm corner radius for fine edge definition
• Compatible with ISO holders; 11° clearance angle

Reliable edge control for consistent turning performance

The SPGN120408 family delivers a reproducible cutting edge thanks to its square form and precise tolerances. As an ISO-standard component, the insert ensures predictable seating and repeatable clamping, which reduces set-up time and variability in serial production. The 90° geometry provides stability in radial cuts, while the 0.8 mm corner radius balances edge strength with the ability to produce accurate profiles and fine surface finishes. For workshops seeking consistent cycle times and reduced rework, this geometry supports steady process results.

Material behaviour and why an uncoated grade can be advantageous

The TH10 grade is an uncoated cemented carbide designed as a sharp, universal option for non-ferrous workpieces and operations where a low-friction, clean cutting edge is required. In such applications the absence of a coating reduces built-up edge tendency and assists in achieving a clean surface finish with lower cutting forces. That behaviour is particularly beneficial when machining aluminium alloys or soft copper-based materials, where shearing rather than ploughing preserves dimensional accuracy and component appearance.

System compatibility and practical mounting considerations

Compatibility with holders is determined by the insert’s shape, clearance angle, tolerance class, fastening method, size and thickness. The insert is supplied in a square form and fits standard ISO external holders or appropriate boring bars when the clamping geometry matches the plate dimensions and 4.76 mm thickness. A complete system comprises the ISO insert, a matched external holder or boring bar, a shim/clamp set and replacement screws; correct combination of these elements secures cutting stability and tool life under varying cutting conditions.

Selection tips and operational benefits for production use

Choosing an insert without a chipbreaker focuses process control on tooling geometry and cutting parameters. The absence of a built-in chipformer here means selecting appropriate feed and speed values and a compatible coolant or chip evacuation strategy. For tasks that prioritise low cutting forces and surface quality, the TH10 grade enables efficient material removal with predictable edge wear. The result is a balance of operational economy and surface integrity that supports high productivity in batch and single-piece production.

FAQ

What materials is this insert best suited for?
The SPGN120408 TH10 is best suited for non-ferrous materials and similar applications where its uncoated cemented carbide grade supports low cutting forces and a clean surface finish.

Can this insert be used for both external and internal turning?
Yes, the ISO-standard square geometry and 90° angle make the insert suitable for both external and internal turning when paired with an appropriate holder.

Does the insert include a chipbreaker?
No, this insert is supplied without a chipbreaker, which allows process control via cutting parameters and holder selection for effective chip evacuation.

How does the 0.8 mm corner radius affect machining?
The 0.8 mm corner radius offers a compromise between edge strength and profile accuracy, improving surface finish while maintaining adequate edge resistance for common turning operations.

What determines compatibility with a tool holder?
Compatibility depends on the insert’s form, clearance angle, tolerance class, fastening method, size and thickness; matching these to the holder ensures secure clamping and stable machining.
