TNMG160408 KS20 — TNMG turning insert (160408) by Tungaloy

The TNMG160408 KS20 is an ISO‑standard triangular indexable insert designed for general turning operations, delivering a balanced mix of wear resistance and edge stability for a wide range of machining tasks.

• ISO‑standard TNMG geometry, 60° included angle
• KS20 Tungaloy carbide grade for wear resistance
• Double‑sided chipbreaker for flexible turning

Productive performance through material and grade selection

The insert is manufactured from cemented carbide and graded KS20, a Tungaloy development that prioritises a balance between wear resistance and toughness. This composition supports extended cutting life under typical turning loads and reduces unplanned indexing, which in turn improves overall process uptime. The combination of a reliable carbide matrix and an application‑oriented grade means the cutting edge retains form under moderate heat and abrasion, resulting in more consistent dimensional accuracy and fewer tool changes during serial production.

Geometry and mounting that ensure consistent cuts

A triangular form with a 60° included angle and a 0.8 mm corner radius delivers predictable chip formation and part finish in many turning tasks. The insert has a 4.76 mm plate thickness and is supplied with a cylindrical hole, which must match the chosen holder’s seat, clearance angle and fastening system. Compatibility is determined by the insert form, clearance angle tolerance, size and thickness; correct holder selection ensures clamping stability and repeatable positioning, reducing vibration and improving surface quality. The ISO designation provides standardised referencing for holder and tool‑post matching.

Versatility and handling benefits for shops

The double‑sided chipbreaker design offers multiple indexable edges per insert, optimising cost‑effectiveness in batch and production turning. The chipbreaker geometry supports controllable chip evacuation and can be paired with the KS20 grade for a balance of edge life and surface integrity. For internal or external turning applications, selecting the appropriate chipbreaker profile and adapting feeds and speeds to the workpiece material will unlock the insert’s full potential. Where process stability is critical, the robust edge and standardised geometry reduce risk of unexpected breaks and shorten setup time.

FAQ

What machining tasks is this insert intended for?
The TNMG160408 KS20 Tungaloy turning insert is designed for turning applications and is suited to both external and internal turning when paired with a compatible holder.

How many usable cutting edges does the triangular, double‑sided insert offer?
With a triangular, double‑sided configuration the insert provides multiple indexable edges, allowing several repositions before replacement; this improves cost efficiency per usable edge.

Which dimensions are critical when checking holder compatibility?
Check the insert size (16 mm), thickness (4.76 mm), the 60° geometry and the cylindrical hole; holder form, clearance angle and fastening must match these parameters for secure clamping.

What does the KS20 grade contribute to performance?
KS20 is a Tungaloy carbide grade formulated to balance wear resistance and toughness, supporting stable cutting edges and longer life in general turning operations.

What corner radius should be expected for edge finish and strength?
The insert features a 0.8 mm corner radius, a compromise between edge strength and surface finish suitable for many finishing and medium‑cut turning tasks.
