CNMG 120408 KS05F ISO turning insert — Tungaloy, 0.8 mm radius, rhombic

A CNMG120408 KS05F indexable turning insert designed for general turning applications, offering balanced wear resistance and stable cutting-edge performance for external and internal turning.

• ISO CNMG geometry for standard toolholders
• KS05F grade for extended wear resistance
• 0.8 mm nose radius for versatile profiling
• Rhombic plate with cylindrical hole for secure clamping

Consistent machining through standardised ISO geometry

The ISO turning insert follows established ISO dimensions, ensuring reliable fit and straightforward interchangeability with compatible holders. Standardisation reduces setup time and simplifies inventory management, while the rhombic form with an 80° included angle provides access to a wide range of turning profiles. Because the insert is manufactured to ISO tolerances, stability in seating and repeatable positioning are ensured, which translates into predictable tool life and fewer rejected parts.

Durable performance thanks to the KS05F grade and carbide substrate

The cutting edge is produced from cemented carbide and finished in Tungaloy's KS05F grade, a composition tailored for a combination of wear resistance and edge toughness. This balance means the insert sustains cutting temperatures and abrasive wear without chipping prematurely, which is particularly valuable in medium-duty turning operations. The result is fewer indexings per component and improved process economy over production runs.

Practical geometry that supports versatile turning tasks

A 0.8 mm nose radius provides a compromise between strength and detail: it is sturdy enough for stable roughing yet precise enough for light finishing and profile work. The plate thickness of 4.76 mm and the central cylindrical hole allow secure clamping and stable cutting conditions, while the double-sided chipbreaker option extends the effective lifetime by offering two cutting edges per index. These features combine to reduce downtime for tool changes and to support consistent surface quality.

Clear benefits for process reliability and shop-floor efficiency

Specifying an insert with standard ISO form and a robust grade like KS05F supports predictable tool behaviour and easier process planning. Compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness — factors that make selection straightforward when paired with the right holder and clamping set. For workshops seeking both repeatability and economical machining, this solution offers a practical route to stable production.

FAQ

What materials is this insert suited for? The CNMG120408 KS05F insert is designed for general turning and the KS05F grade complements geometry to handle a broad material range with emphasis on wear resistance and edge stability.

How does the 0.8 mm nose radius affect surface finish? A 0.8 mm nose radius provides a balance between edge strength and surface quality; it supports stable cuts for consistent finishes while remaining versatile for light profiling.

Is the insert compatible with standard CNMG toolholders? Yes — compatibility depends on ISO CNMG form, clearance angle, tolerance class, fixing method, size and thickness; the CNMG120408 designation follows ISO standards for straightforward interchange.

Can both sides of the insert be used? The insert features a double-sided chipbreaker, enabling two usable cutting edges and prolonging the effective life before replacement.

What components are required for a full system setup? A complete system typically comprises the ISO turning insert, a matching external holder or boring bar, a clamping pad or clamp kit and replacement screws where applicable.
