SNGN 120304 LX11 Wendeplatten - Tungaloy

The SNGN120304 LX11 insert combines ISO-standard geometry, a Tungaloy LX11 carbide grade and a compact 0.4 mm corner radius to deliver stable cutting performance in turning operations; its square 12 mm form and 3.18 mm thickness suit standard ISO holders. Order the insert directly via Metav Werkzeuge or ask the consultants for application guidance.

SNGN 120304 LX11 – ISO turning insert for external and internal turning (Tungaloy)

The SNGN120304 LX11 is an ISO-standard carbide turning insert designed for precision external and internal turning where wear resistance and edge stability are required.

• ISO SNGN geometry for standardised holders
• Tungaloy LX11 grade for balanced wear resistance
• Square 12 mm insert with 0.4 mm corner radius
• 3.18 mm thickness compatible with 90° cutting angle

Consistent metal‑cutting performance for repeatable results

The insert is built on an ISO-standard SNGN geometry, which ensures predictable toolpath behaviour and simple interchangeability across compatible toolholders. The combination of carbide substrate and the LX11 grade balances wear resistance and toughness, reducing edge chipping in interrupted cuts while maintaining a stable cutting edge for continuous turning. For production environments this translates into fewer indexings, longer tool life and more consistent component dimensions.

Clear compatibility and secure clamping reduce downtime

Compatibility with a toolholder depends on form, relief angle, tolerance class, fixing method, size and thickness; the square 12 mm format and 3.18 mm plate thickness match standard ISO SNGN holders. The insert is supplied without a central hole and without a chipbreaker, so the correct clamping shim or clamp set and the recommended screw must be used to secure the insert. Proper seating and torque ensure repeatable positioning and help maintain surface finish and dimensional control.

Grade and geometry choice improves process reliability

The LX11 grade from Tungaloy is formulated to provide a compromise between abrasion resistance and edge toughness, making it suitable for a broad range of turning operations. The 0.4 mm corner radius offers a modest edge strength increase for general finishing and light roughing, while the 0° relief angle and 90° orientation suit conventional external and internal turning set-ups. Selecting this configuration supports stable chip formation and predictable tool wear, which assists process planning and cost calculations.

Practical benefits for workshop and production use

Using ISO‑compliant inserts simplifies inventory and reduces set‑up complexity across machines. The square plate shape allows four indexable edges, which improves economics per insert. The absence of an integrated chipbreaker means chip control must be addressed via cutting parameters and toolholder orientation; however, the robust Tungaloy carbide grade helps maintain a sharp cutting edge for longer, improving component surface quality and cycle time consistency. For specialised materials or applications, pairing the insert with the correct holder and machining data is recommended.

FAQ

What materials is this insert suitable for?
The SNGN120304 LX11 insert is intended for general turning; the LX11 grade offers balanced wear resistance and toughness suitable for a wide range of steels and similar materials in standard turning applications.

How is the insert fixed in the holder given it has no central hole?
This square insert is secured in compatible ISO SNGN toolholders using the appropriate clamp or shim system; correct seating and torque are essential for repeatable performance with the SNGN120304 LX11.

Does the insert include a chipbreaker for improved chip control?
The SNGN120304 LX11 is supplied without a chipbreaker, so chip formation is managed via cutting parameters and holder geometry rather than an integrated chip control feature.

What are the key dimensions to check for holder compatibility?
Verify plate size (12 mm), plate thickness (3.18 mm), corner radius (0.4 mm) and the SNGN form designation when matching the insert to a toolholder.

Can this insert be indexed to use multiple cutting edges?
Yes, the square plate shape provides multiple indexable edges; the SNGN120304 LX11 can be rotated to present fresh cutting edges as they wear.
