Durable cutting performance that reduces interruptions

The combination of the KS20 carbide grade and the insert’s geometry produces a balance of wear resistance and toughness that supports longer tool life and fewer indexings. The substrate and grade selection from Tungaloy aim to maintain a stable cutting edge under varied cutting conditions; this means predictable tool change intervals and lower tooling costs per finished part. Where productive turning is required, the performance focus is on consistent material removal rates and reduced secondary operations, enabling smoother production flows and improved machine utilisation.

Geometry and chip control for repeatable surface quality

A triangular plate with a 60° included angle gives rigidity and versatility in turning tasks, while the 0.4 mm nose radius helps to achieve narrow chamfers and controlled surface finish. The double-sided chipbreaker design promotes reliable chip formation for a wide range of cutting depths and feeds; chips are guided away from the cutting zone, reducing rework and decreasing the risk of workpiece damage. The presence of a cylindrical hole and the standardised dimensions ensure secure clamping in compatible holders, which is essential for maintaining concentricity and repeatable tolerances in serial production.

Straightforward system integration with ISO tooling

Being part of an ISO-standard turning insert family simplifies tool selection and inventory management. Compatibility with external holders, boring bars, shims and clamping sets is determined by form, relief angle, tolerance class, attachment type, size and thickness, so the insert can be integrated into existing tool systems without complex requalification. The insert’s 4.76 mm thickness and 16 mm plate size match common holder specifications, reducing setup time and minimising the need for custom fixtures.

Practical application guidance and recommended use

Designed specifically for turning operations, this indexable plate is best deployed when machining tasks demand a compromise between edge life and impact resistance. Select the chipbreaker and cutting parameters according to the workpiece material and the machine’s rigidity to achieve ideal results; the grade is intended to complement the geometry by providing balanced edge stability and wear behaviour. For unfamiliar applications or where material specifics are critical, technical advice can clarify grade selection and cutting data to avoid trial-and-error and to protect component quality.

FAQ

What is the primary application for this insert?
The TNMG160404 KS20 Tungaloy indexable insert is intended for external and internal turning operations, offering a balance of wear resistance and edge stability for general turning tasks.

How does the KS20 grade affect tool life?
The KS20 carbide grade from Tungaloy is formulated to combine wear resistance with sufficient toughness, which helps to extend edge life and maintain machining consistency under variable conditions.

Which holders are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, attachment method, size and thickness; holders matching the ISO TNMG size and a cylindrical hole clamping system will accept this insert.

Can this insert be used for fine finishing?
Yes — the 0.4 mm nose radius and stable geometry support controlled surface finishes when combined with appropriate feeds and speeds.

Is the insert reversible or single-use per edge?
The triangular design with a double-sided chipbreaker provides multiple cutting edges; each edge can be indexed according to wear, allowing several uses before the insert must be replaced.
