CNGA 120416 LX10 Turning Insert — Tungaloy, rhombic 80° (LT chipbreaker)

CNGA120416-LT LX10 Tungaloy turning insert for ISO-standard external and internal turning, designed for secure clamping and consistent edge life

• ISO CNGA 120416 form, 80° geometry
• LX10 grade for wear resistance
• 1.6 mm corner radius for robust cutting edges
• LT chipbreaker for controlled chip formation

Consistent cutting performance through balanced grade and geometry

The CNGA120416-LT insert combines the LX10 cutting grade with a rhombic 80° geometry to deliver predictable tool life and surface quality during turning. The carbide substrate provides the hardness required for abrasion resistance while the grade adds toughness, reducing the risk of premature edge chipping. A 1.6 mm corner radius supports longer tool life on interrupted cuts and provides improved resistance against edge deformation, which translates into fewer insert changes and higher uptime on the machine.

Clear compatibility reduces set-up complexity

Compatibility with ISO-style holders is determined by the insert’s shape, relief angle, tolerance class, fastening method, size and thickness. The rhombic form and standardised ISO designation simplify selection of a matching external holder or boring bar, while the cylindrical hole enables secure fastening and reliable repeatability when clamping with a suitable underlay or clamping set. This standardisation reduces trial-and-error during tool assembly and shortens set-up times on the shop floor.

LX10 and LT chipbreaker: predictable chips and longer productivity

The LX10 grade is engineered to combine wear resistance and edge stability, making it suitable for general turning applications where a compromise between life and toughness is needed. Paired with the LT chipbreaker, the insert offers improved chip control for a wide range of cutting conditions; select the chipbreaker and grade according to the workpiece material and the required stability to achieve the best balance of surface finish and productivity. Choosing the correct combination helps lower total machining costs by extending effective tool life.

Practical handling, mounting and selection guidance

The insert’s 4.76 mm thickness and 12 mm inscribed size give a stable clamping surface that supports heavier cuts while preserving rigidity. Ensure a matching clamping pad and the correct replacement screws are used; the system typically comprises the insert, a corresponding external holder or bar, an underlay/clamping set and spare screws. For best results, check holder compatibility against the ISO designation and the insert’s geometrical data before ordering. If unsure about holder choice or process parameters, the available technical advice can guide correct selection and prevent costly mistakes.

FAQ

What turning operations suit this insert?
The CNGA120416-LT LX10 Tungaloy turning insert is intended for both external and internal turning where a rhombic 80° geometry and a 1.6 mm corner radius provide a balance of strength and surface finish.

Which workpiece materials are appropriate with the LX10 grade?
The LX10 grade offers a compromise between wear resistance and toughness, making the insert suitable for a broad range of general turning tasks; select the LT chipbreaker and cutting data according to material and component rigidity.

How does the cylindrical hole affect clamping?
A cylindrical hole allows positive indexing and secure fastening with the recommended underlay or clamping set, improving repeatability and reducing movement under load.

Can the insert be used with any CNGA holder?
ISO-standard form and the CNGA120416 designation permit use with compatible CNGA holders, but final compatibility depends on relief angle, tolerance class, fastening method, size and thickness — verify the holder’s specifications before fitting.

What advantage does the 1.6 mm corner radius provide?
The 1.6 mm radius increases edge strength and improves resistance to chipping on interrupted cuts, helping to extend effective tool life and improving process stability.
