CNGG120402 KS05F Turning insert — rhombic 80° for turning, Tungaloy

CNGG120402 KS05F is an ISO‑standard rhombic turning insert designed for external and internal turning tasks where a balanced mix of wear resistance and edge stability is required

• ISO rhombic insert, 80° cutting angle
• KS05F grade for wear resistance
• 0.2 mm corner radius for fine cuts
• Double-sided chipbreaker, cylindrical hole

Precise geometry for repeatable turning performance

The CNGG120402 KS05F indexable plate is manufactured from cemented carbide and offers an 80° cutting geometry in a rhombic shape, making it suitable for a broad range of turning operations. The low 0.2 mm corner radius supports fine finishing and reduced cutting forces in interrupted cuts, while the double-sided design extends tool life by providing two usable cutting edges. Compatibility with ISO holders is determined by form, clearance angle, tolerance class, fastening and thickness, which ensures predictable seating and repeatable machining results.

Material grade and what it delivers on the shop floor

The KS05F grade from Tungaloy combines enhanced wear resistance with sufficient toughness, optimised for stable chip formation during turning. In practice this means longer edge life under mixed cutting conditions and fewer indexings, translating into improved uptime and lower tooling costs per component. For less experienced buyers, the grade can be read as a practical compromise between abrasion resistance and chipping resistance for general steel and alloy turning applications.

Fitment and system assembly explained simply

The insert is supplied as an ISO‑format plate intended for use with a matching external holder or boring bar. Correct clamping requires attention to the insert thickness of 4.76 mm, the cylindrical centre hole and the holder’s tolerance class; complementary parts include an underlay/locking pad and spare screws. Specifying the holder by form and size rather than by product name avoids mismatch and secures optimal clamping, which is essential for consistent chip control and surface quality.

Practical benefits in everyday production

Using an ISO rhombic insert with a double-sided chipbreaker delivers two principal benefits: economical edge usage and predictable chip formation. The cylindrical hole aids secure locating and straightforward replacement, while the modest corner radius supports improved surface finish on thin-walled or delicate workpieces. These features combine to reduce cycle time variability and to make set‑up and re‑indexing faster during batch production.

Choosing the right cutting package for the job

Select a chipbreaker and grade based on the workpiece material, cutting parameters and machine stability. For most turning tasks where a balance of economy and edge robustness is required, the KS05F grade paired with a medium‑strength chipbreaker is appropriate. If the process demands higher thermal resistance or heavier interrupted cuts, consider grades with higher toughness; conversely, for only fine finishing, a harder, more wear‑resistant grade may pay off over time.

FAQ

What material is this insert made of?
The CNGG120402 KS05F turning insert from Tungaloy is made of cemented carbide, a durable substrate chosen for wear resistance and rigidity.

Which operations suit this insert best?
This rhombic ISO insert is intended primarily for external and internal turning; the combination of KS05F grade and a 0.2 mm corner radius suits general turning and fine finishing tasks.

How does the KS05F grade affect tool life?
KS05F provides a balance of wear resistance and toughness that improves edge stability, resulting in fewer indexings and more consistent tool life under mixed cutting conditions.

Is the insert compatible with standard ISO holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the plate is ISO‑format and requires a matching holder and clamping set.

What technical data should be specified when ordering replacements?
Specify the ISO designation (CNGG120402), grade (KS05F), thickness (4.76 mm), corner radius (0.2 mm) and the manufacturer SKU (TUN6934780) to ensure correct replacement.
