TNGN 160408 LX21 Tungaloy indexable insert for turning

A TNGN160408 LX21 ISO‑conforming triangular indexable insert designed for external and internal turning applications, supplying a balance of wear resistance and edge stability.

• ISO‑standard triangle insert for turning
• LX21 grade: wear resistance and edge stability
• Carbide body for consistent cutting performance
• 0° clearance with 60° insert angle for stability

Dependable edge life that keeps production moving

This triangular indexable insert is manufactured from carbide and specified to ISO dimensions, delivering predictable tool life in repetitive turning operations. The LX21 grade from Tungaloy combines wear resistance and toughness to maintain a sharp cutting edge under varied cutting conditions, reducing unplanned tool changes. For many machining scenarios this results in fewer interruptions on the shop floor and a more consistent surface finish on the workpiece. The design is particularly suited to stable setups and applications where repeatability and component tolerance are essential.

Designed for straightforward integration with ISO holders

Compatibility with tooling systems is governed by the insert’s form, clearance angle, tolerance class, fastening method, size and thickness. The ISO designation ensures the insert fits established clamping systems when the corresponding holder geometry is selected. The insert is used together with a suitable external holder or boring bar, a shim or clamp set and replacement screws to form a complete cutting system. Choosing matching components simplifies set‑up and reduces the likelihood of clamping errors, which supports more efficient machining cycles and safer operation.

Geometry and dimensions that promote cutting stability

The triangle form with a 60° included angle and a corner radius of 0.8 mm offers a robust cutting edge that resists chipping during medium to heavy cuts. With a plate size of 16 mm and a thickness of 4.76 mm, the insert provides mechanical stability in the pocket and supports higher feed rates where the machine and workpiece setup permit. The specified 0° clearance contributes to a consistent cutting geometry for profiles and external turning tasks. Absence of a dedicated chipbreaker means chip control must be managed by process parameters or by selecting an insert variant with an integrated chipbreaker where chip evacuation is critical.

Match the grade and geometry to the workpiece for best results

The LX21 grade is engineered to complement the insert geometry by delivering a balance between abrasion resistance and edge toughness, which helps when machining a broad range of materials under varying conditions. For best performance, select cutting parameters and a clamping assembly that reflect the material, the type of cut and the machine rigidity. When interrupted cuts or heavy radial engagement are expected, favour a stable holder and reduced cutting speeds; for continuous finishing passes, the combination of geometry and grade supports improved surface quality. Where chip control or specific surface requirements are critical, consider grade or geometry alternatives that include dedicated chipbreakers.

FAQ

What applications is this insert intended for?
The TNGN160408 LX21 insert is intended for external and internal turning where ISO‑conforming triangular inserts are appropriate; it is suited to general turning tasks that require a balance of wear resistance and edge stability.

Which workpiece materials are best paired with this grade?
The LX21 grade is formulated to offer a compromise of wear resistance and toughness, making the insert suitable for a broad range of materials; the final choice should align with the specific workpiece material, machining strategy and stability of the setup.

How is compatibility with a toolholder determined?
Compatibility is defined by the insert form, clearance angle, tolerance class, fastening type, size and thickness; matching these attributes with the holder and clamp set ensures correct seating and safe clamping.

What does the 0.8 mm corner radius mean for performance?
A corner radius of 0.8 mm increases edge strength and improves resistance to chipping in medium duty cuts, while affecting the achievable surface finish and cutting forces compared with smaller radii.

Does this insert include a chipbreaker?
This variant is supplied without a chipbreaker; chip control must therefore be managed by cutting parameters or by selecting a variant with an integrated chipbreaker if required.
