CGWT L2020- indexable insert for turning by Tungaloy — rhombic L2, 30° clearance

A CGWT L2020- indexable insert engineered for ISO‑standard external and internal turning, designed to deliver controlled chip formation and reliable seating in compatible holders.

• ISO‑standard indexable insert, rhombic shape
• 30° clearance angle for predictable cutting
• Cylindrical hole with 40°–60° one‑sided countersink
• Thickness 2.38 mm, size L2, single‑sided chipbreaker

Predictable cutting performance for turning operations

The insert is manufactured to ISO standards, ensuring repeatable orientation and secure clamping in standard holders. Its rhombic geometry and 30° clearance produce a stable cutting angle that supports consistent tool engagement and reduced vibration. Made from carbide, the geometry and grade aim to balance wear resistance and toughness, so chips are formed in a controlled manner; this improves process stability and contributes to longer usable life per edge. The construction supports both finishing and medium roughing, depending on holder rigidity and the chosen chipbreaker.

Compatibility and mounting explained for quick integration

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening method, size and plate thickness; the insert’s cylindrical hole with a one‑sided countersink (40°–60°) ensures positive location and clamping in axial and radial seats. With a thickness of 2.38 mm and size L2, the insert fits common ISO carrier designs and can be fastened using the standard clamp and screw arrangement. The single‑sided chipbreaker supports defined chip control on the active edge, simplifying the selection of holders and screws for productive toolset assembly.

Broader material range and recommended applications

The design is intended for external and internal turning where a medium to high degree of process stability is required. Selecting an appropriate chipbreaker and carbide grade according to the workpiece material, machining type and machine rigidity is advised to achieve optimal results. For interrupted cuts or less rigid set‑ups, choose a tougher grade; for continuous finishing cuts, favour a wear‑resistant grade. The system approach—insert, holder and correct tightening—ensures repeatable geometry and consistent surface finish.

Workshop economy and system benefits

Using ISO‑conforming inserts simplifies stockkeeping and reduces setup time across multiple machines. The standardised plate form and hole design allow rapid replacement without bespoke fixtures, supporting higher uptime. Where inventory management and predictable process output matter, these inserts offer a balance of dependable edge life and straightforward disposal and rotation strategies. The modular system—insert, compatible outer holder, clamp plate and replacement screws—facilitates fast maintenance cycles and reproducible part quality.

FAQ

What cutting applications suit this insert best? This indexable insert is intended for both external and internal turning operations; the geometry and chipbreaker make it suitable for finishing and medium roughing when combined with an appropriate holder and carbide grade.

How does the hole and countersink affect clamping? The cylindrical hole with a 40°–60° one‑sided countersink provides precise location and secure clamping, ensuring repeatable seating of the insert in compatible ISO holders.

Which size and thickness are standard for this series? The insert is provided in size L2 with a plate thickness of 2.38 mm, matching common ISO holder specifications for this geometry.

Can this insert be used for interrupted cuts? Yes; for interrupted cuts it is advisable to select a tougher carbide grade and ensure the holder and machine set‑up deliver sufficient rigidity to protect the cutting edge.

What distinguishes the rhombic form in practical terms? A rhombic plate offers versatile approach angles and improved access in confined contours; combined with the 30° clearance it enables controlled cutting engagement and predictable chip flow.
