SNGN 120720 LX11 indexable turning insert — carbide, 2 mm corner radius, Tungaloy

The SNGN 120720 LX11 is an ISO-designation square indexable insert intended for precision external and internal turning, offering a balanced combination of wear resistance and edge stability for versatile machining tasks.

• ISO-standard SNGN geometry for broad compatibility
• LX11 Tungaloy grade: wear-resistant and tough
• 2 mm corner radius for stable edge strength
• 0° rake angle for general-purpose turning

Predictable fits through ISO-standard geometry

The ISO designation and square format deliver a predictable seating and interchangeability with matching toolholders, reducing setup variability. Compatibility with a holder depends on form, rake angle (0°), tolerance class, fastening method, nominal size and thickness, which simplifies tool management when multiple tool types are used on a lathe. The standardised SNGN geometry supports quick replacement and repeatable clamping, helping maintain process stability across series production runs.

LX11 grade: balanced wear resistance and toughness

The LX11 grade by Tungaloy combines wear resistance, toughness and cutting-edge stability to address a range of turning requirements. This carbide grade is formulated to extend tool life under varied cutting conditions while preserving the integrity of the cutting edge, which translates into fewer interruptions for insert changes and more consistent surface finishes. The grade’s composition complements the insert geometry to provide dependable performance in both external and internal turning tasks.

Practical design that reduces inventory complexity

A square 12 mm insert with a 2 mm corner radius and a plate thickness of 7.94 mm offers a robust cutting edge and straightforward seating. The insert is supplied without a hole and carries no chipbreaker, making it suitable for applications where the holder or clamping system determines chip control. The simple system setup — an ISO insert plus the appropriate external holder or boring bar, a shim or clamp set and replacement screws — allows for efficient spare-parts stocking and predictable tool-change procedures, decreasing machine downtime.

Selection advice for stable machining results

Choose the chipbreaker and grade appropriate to the workpiece material, machining type and machine stability to make the most of the insert’s characteristics. The SNGN120720 geometry, combined with the LX11 grade, favours operations where edge robustness and consistent wear behaviour are priorities. When matching the insert to a holder, confirm form factor, clearance and clamping dimensions to ensure secure fixation and correct cutting angles for the intended turning strategy.

FAQ

What machining tasks is this insert designed for?
The SNGN120720 LX11 insert is designed for precision external and internal turning, providing a balance of wear resistance and edge stability for a variety of turning operations.

How does the LX11 grade affect tool life?
The LX11 Tungaloy grade combines wear resistance and toughness to extend service life and maintain cutting-edge integrity under changing cutting conditions.

Which holders are compatible with this ISO geometry?
Compatibility is determined by insert form, rake angle (0°), tolerance class, fastening method, size (12 mm) and thickness (7.94 mm); matching holders that accept SNGN geometry will seat the insert correctly.

Is there a chipbreaker on the insert?
This insert is supplied without a chipbreaker, so chip control is achieved via the chosen holder and machining parameters.

What does the 2 mm corner radius mean for cutting?
A 2 mm corner radius increases edge strength and reduces the risk of chipping during interrupted cuts, improving stability in general-purpose turning.
