TNGA 160408 LX21 turning insert — Tungaloy, triangle indexable insert for turning

TNGA 160408 LX21 is a triangular indexable insert designed for multidirectional turning in the AddMultiTurn system, suited to longitudinal, facing and profile turning operations.

• Multidirectional turning insert
• Tungaloy LX21 grade for wear resistance
• Triangle form, 16 mm size, 60° angle
• 0.8 mm corner radius, cylindrical hole

Greater production flexibility with a multidirectional insert

The AddMultiTurn series provides a compact solution for operations that require changing cutting directions without tool exchange. The triangular indexable insert offers three usable edges in a small footprint, enabling faster cycle times and reduced tool inventory. The multidirectional layout of the system reduces non-cutting time and supports efficient set-ups for combined longitudinal, facing and profile turning. As a result, the machining cell benefits from improved throughput while maintaining process stability and repeatable part quality.

Robust cutting performance from the LX21 grade

The Tungaloy LX21 carbide grade combines wear resistance, toughness and cutting-edge stability to meet the demands of diverse turning tasks. The material composition is optimised to resist flank wear and edge chipping under interrupted cuts, which extends effective tool life and keeps surface finish consistent. When tool life is extended, the total machining cost per component decreases; the insert’s carbide construction and geometry balance hardness and toughness for reliable performance across a broad range of steels and common alloys.

Geometry that supports precision and secure clamping

The triangular insert with a 16 mm inscribed circle and a 60° included angle delivers stable cutting engagement and a predictable cutting force vector. The 0.8 mm corner radius improves edge strength for finishing and light-medium roughing, while the cylindrical hole enables positive, repeatable clamping in holders designed for the AddMultiTurn series. The system comprises the holder, indexable inserts and a clamping solution, ensuring secure seating and simple indexing without compromising concentricity or run-out during high-speed rotations.

Clear application scope and handling notes

Designed for turning, the insert is supplied without a dedicated chipbreaker, which makes it particularly suitable for operations where chip form is managed by tool path, feeds and coolant strategy. The insert’s triangular form and hole detail suit modular holders that accept inserts with a central fixing, and the plate thickness of 4.76 mm offers a solid contact area for clamping forces. Handling and storage of indexable inserts should follow standard precautions for carbide tools: avoid impact, store in original packaging and inspect seating surfaces before assembly to ensure consistent clamping and repeatable cutting results.

FAQ

What turning tasks is this insert designed for?
The TNGA 160408 LX21 Tungaloy indexable insert is designed for longitudinal, facing and profile turning within a multidirectional AddMultiTurn set-up, providing flexibility across common turning operations.

Which materials can be machined with this grade?
The LX21 grade of the Tungaloy insert offers a balance of wear resistance and toughness that suits a wide range of steels and general turning applications; selection should follow the workpiece material and machining parameters.

Does the insert include a chipbreaker?
This insert is supplied without a dedicated chipbreaker; chip control is achieved through feed, speed and holder/coolant strategy when using the TNGA 160408 LX21 insert.

What holder requirements are there for clamping?
The insert features a cylindrical central hole for positive clamping; compatible holders in the AddMultiTurn family ensure secure seating and repeatable indexing for the TNGA 160408 geometry.

How many cutting edges are available per insert?
The triangular form provides three cutting edges per insert; the geometry and LX21 grade together support reliable edge performance across those indexed positions.
