TPGN 110304 LX21 Tungaloy turning insert — triangular ISO insert, 11° clearance

The TPGN110304 LX21 is a triangular ISO turning insert designed for external and internal turning operations, offering a 0.4 mm corner radius for fine contouring and predictable tool life.

• ISO‑standard triangular insert
• LX21 grade for wear resistance
• 0.4 mm corner radius for fine contours
• 11° clearance angle for stable cutting

Optimised performance for productive turning

The LX21 grade, developed for Tungaloy, combines wear resistance and edge stability to extend cutting intervals and reduce downtime. In practice, this means fewer insert changes and a steadier surface finish on turned components. The carbide substrate delivers rigid support for the cutting edge, while the geometry balances chip formation and edge strength; this results in consistent cycle times and improved process reliability in a production environment.

Predictable clamping and straightforward compatibility

The insert follows ISO dimensions and mounting logic, so matching a proper holder or boring bar is determined by form, clearance, tolerance class, fastening method, size and thickness. The triangular 11 format and the absence of a hole simplify selection for many standard external and internal turning holders. With a plate thickness of 3.18 mm and standard tolerance control, the system ensures reproducible seating and torque transmission, which supports stable cutting conditions and repeatable part accuracy.

Geometry that supports surface finish and tool life

A 0.4 mm corner radius and an included angle of 60° provide a good compromise between edge strength and finish capability: small radii allow finer detail and lower cutting forces in finishing passes, while the chosen clearance of 11° reduces rubbing and heat at the flank face. The insert has no integrated chipbreaker, so chip control is addressed by selecting the appropriate chip‑forming features and grade for the workpiece and cutting conditions, allowing flexible process optimisation for both roughing and finishing tasks.

Practical selection and application guidance

Intended specifically for turning, the insert is best used where repeatable performance and straightforward tool management are priorities. Choose the right chipbreaker and application settings according to the workpiece material and stability of the set‑up. Where chip control or specialised cutting behaviour is required, pair the insert with a compatible holder and the correct clamping kit; spare screws and underlay shims are recommended items to keep as part of a reliable maintenance routine.

FAQ

What applications is this insert suitable for?
The TPGN110304 LX21 insert is designed for external and internal turning; it is intended where reliable edge stability and repeatable clamping are required.

Does the insert have a chipbreaker or a hole for mounting?
This insert is supplied without a chipbreaker and without a hole; clamping is achieved via the matching ISO holder and clamping kit.

How does the LX21 grade affect tool life?
The LX21 grade enhances wear resistance and edge stability, which can extend intervals between indexings and support more consistent surface quality under stable cutting conditions.

Which geometry parameters should be checked for holder compatibility?
Compatibility is governed by the insert form, clearance angle, tolerance class, fastening method, size (11) and thickness (3.18 mm); matching these ensures correct seating and secure clamping.

Can this insert be used for finishing passes?
Yes; the 0.4 mm corner radius and 11° clearance allow fine contouring and good surface finish in finishing operations when cutting parameters are set accordingly.
