SPGN 120308 LX10 — Turning insert (carbide) by Tungaloy — 0.8 mm radius, 11° relief

SPGN120308 LX10 Tungaloy insert is an ISO‑standard square indexable insert for general turning applications, offering a balance of wear resistance and toughness suitable for a wide range of machining tasks.

• ISO 120308 square insert
• LX10 grade for wear resistance
• 0.8 mm corner radius for stable edge
• 11° relief angle for reliable engagement

Longer tool life through geometric stability and material choice

The insert is manufactured from carbide and specified in the LX10 grade to combine wear resistance with sufficient toughness for interrupted and continuous cuts. The result is a predictable edge behaviour and longer usable life under typical turning conditions. The 0.8 mm corner radius helps distribute cutting forces over a larger area, reducing edge chipping and improving surface finish on parts where a defined corner form is required. By integrating these properties, the insert supports higher productivity and fewer tool changes, which directly reduces machine downtime and boosts throughput in batch and single‑piece production.

Consistent setup and compatibility to reduce downtime

Designed as an ISO format insert (120308), compatibility with holders depends on form, relief angle, tolerance class, clamping style, size and thickness; using a correctly matched square insert holder ensures secure clamping and repeatable positioning. The insert’s 11° relief angle and the standard thickness of 3.18 mm permit straightforward mounting in common external holders and boring bars, making tool changeover fast and predictable. A simple, repeatable setup improves process stability and makes it easier to implement standardised cutting parameters across machines and shifts.

Practical advantages in machining performance

For turning tasks that demand a balance between tool life and edge integrity, the combination of LX10 grade and a medium corner radius delivers reliable performance across steels, castings and various alloyed materials when operated within recommended cutting data. The absence of a chipbreaker on this variant directs selection towards applications where either the machine’s coolant flow or fixture arrangement controls chip evacuation, or where manual chip management is preferred. Where chip control is essential, pairing this insert with a compatible geometry or holder that features chip deflection is recommended.

How to choose this insert for production needs

Select this insert when process consistency, straightforward indexing and a robust cutting edge are priorities. Its square form provides four usable cutting edges per index, offering economical edge utilisation in repetitive turning operations. When softer, gummy materials are in use or very fine surface finish is required, consider matching the LX10 grade with adjusted speeds and feeds to exploit its wear resistance while avoiding built‑up edge. For heavy interrupted cuts, the insert’s carbide composition and geometry support stable cutting, provided the machine and clamping system deliver the required rigidity.

FAQ

What materials is this insert suitable for?
The SPGN120308 LX10 Tungaloy insert is specified for general turning and performs well on a broad range of materials when cutting data are matched to the workpiece and rigidity of the setup.

How many cutting edges does the insert provide?
As a square indexable insert, the SPGN120308 LX10 offers four usable cutting edges per index, improving economy in high‑volume turning operations.

Is a chipbreaker included with this variant?
This particular insert is supplied without a chipbreaker; chip control is achieved via holder geometry, cutting parameters, and coolant strategy when necessary.

How does the 0.8 mm radius affect surface finish?
The 0.8 mm corner radius provides a compromise between strength and form definition: it stabilises the cutting edge and often improves finish compared with very small radii, while still allowing controlled profile generation.
