CNGA120412 LX10 indexable turning insert – Tungaloy, 80° approach, 1.2 mm radius

CNGA120412 LX10 is an ISO‑standard indexable turning insert designed for external and internal turning operations with an LX10 carbide grade optimised for wear resistance and edge stability

• ISO‑standard rhombic insert CNGA120412
• LX10 Tungaloy carbide grade
• 80° approach angle, 1.2 mm corner radius
• Cylindrical hole, 4.76 mm plate thickness

Consistent cutting performance and measurable process gains

The CNGA120412 LX10 indexable insert delivers a predictable combination of edge stability and wear resistance through the LX10 cutting grade and a precise rhombic geometry. The 80° approach form reduces radial cutting forces in many external turning tasks, which can translate into longer tool life and fewer insert changes. The insert’s 1.2 mm corner radius supports robust edge strength for semi‑finishing cuts while permitting acceptable surface quality, helping to reduce cycle times and improve throughput in production environments.

Simple holder compatibility and dependable clamping

ISO designation and standardised mounting mean the insert integrates with a wide range of external holders and boring bars when the holder matches the insert’s form, clearance angle, tolerance class, fastening method, size and thickness. The cylindrical hole and standardised dimensions (12 mm size, 4.76 mm thickness) ensure secure clamping and repeatable seating. This clarity in fitment reduces setup time and minimises the risk of mismatched assemblies, supporting consistent part quality and easier inventory management across toolrooms.

Material chemistry and application‑oriented grade benefits

Manufactured from cemented carbide, the LX10 grade was selected to balance wear resistance, toughness and cutting‑edge stability, making it suitable for a broad spectrum of turning tasks. The grade complements the insert geometry so that the required combination of abrasion resistance and fracture toughness is achieved for typical external and internal turning operations. Where surface finish and edge security matter, the LX10 composition helps maintain cutting‑edge integrity over extended tool life, reducing unscheduled downtime.

Process reliability, chip control and practical system setup

This ISO‑norm insert is supplied without a dedicated chipbreaker, so chip control should be matched to workpiece material, machining parameters and toolholder rigidity; the insert is intended as part of a system comprising an ISO‑compatible insert, a matched external holder or boring bar, a support pad/clamping kit and spare clamping screws. The standardised form and ISO labelling aid procurement and tool planning, while the robust design improves repeatability from one index to the next, supporting stable machining in series production.

FAQ

What materials can this insert machine effectively?
The LX10 grade in the CNGA120412 insert is formulated to offer a broad workpiece spectrum; it provides good wear resistance and edge stability for many steel and alloy turning tasks.

How does the CNGA120412 mount in a toolholder?
Mounting is by the standard central cylindrical hole and seat; compatibility depends on matching the holder to the insert’s form, clearance angle, tolerance class, fastening method, size and thickness.

Is this insert indexable for repeatable tool changes?
Yes, the CNGA120412 indexable insert is ISO‑standardised for repeatable indexing and seating, enabling quick rotation to a fresh cutting edge and consistent geometry across changes.

What is the recommended use for the LX10 grade?
The LX10 Tungaloy grade complements the insert geometry by providing a balance of wear resistance and toughness, making it suitable for reliable turning operations where edge stability is important.
