TNMG 160412 KS20 indexable turning insert — ISO turning insert for Drehen, Tungaloy

A TNMG160412 KS20 indexable insert designed for external and internal turning in ISO holders, providing a balance of wear resistance and edge stability for a wide range of turning tasks

• ISO TNMG form compatible with standard holders
• KS20 Tungaloy carbide grade with balanced properties
• 60° triangular form with 1.2 mm nose radius
• Double-sided chipbreaker and cylindrical-hole fixing

Engineered for consistent process performance

The insert is manufactured from cemented carbide in the KS20 Tungaloy grade, which combines wear resistance and toughness to maintain cutting-edge stability during both steady and interrupted cuts. That balanced material behaviour reduces downtime for insert changes and supports higher process reliability in series production. The ISO design ensures ISO compatibility with standard TNMG toolholders; compatibility is determined by form, relief angle, tolerance class, fixing and size, allowing a straightforward integration into existing tool systems without altering set-up strategies.

Geometry that enhances surface finish and tool life

A 60° triangular form with a 1.2 mm nose radius and a plate thickness of 4.76 mm provides versatility between light finishing and medium turning operations. The chosen nose radius helps to improve surface quality while distributing cutting forces to protect the edge under variable cutting conditions. The double-sided chipbreaker and the cylindrical-hole fixing support quick indexation and secure clamping, making the insert economical through doubled life per index and reduced handling time in the production cycle.

Application focus and handling recommendations

Intended specifically for turning, the insert complements its geometry with the KS20 grade to offer a well‑rounded solution where both edge stability and wear resistance are necessary. Selection of the chipbreaker and the grade should match the workpiece material, machining strategy and machine stability to gain the greatest benefit from the insert’s properties. The triangular profile enables three usable edges per index, improving cost-efficiency, while the ISO form and mounting style fit established clamping systems and replacement procedures in modern turning centres.

FAQ

What holder compatibility is required for correct fitment?
Compatibility depends on the holder’s TNMG form, relief angle, tolerance class, fixing and size; the TNMG160412 KS20 insert is made for ISO TNMG toolholders.

How many usable cutting edges are available per insert?
The triangular insert provides three usable edges per index, and the double-sided chipbreaker doubles the available edges for cost-effective indexation.

Which properties does the KS20 grade provide?
The KS20 Tungaloy grade offers a balance of wear resistance and toughness, giving stable cutting-edge behaviour for general turning applications.

Is the insert suitable for interrupted cuts?
Yes; the combination of the KS20 grade and robust geometry supports intermittent cutting where edge stability is required.

What fixes the insert to the holder?
The insert uses a cylindrical-hole fixing and standard clamping components, matching ISO TNMG mounting practice.
