CNMG 120404 T5105 Wendeplatten - Tungaloy

Take advantage of the combination of CVD-coated cemented carbide T5105, ISO CNMG geometry and a 0.4 mm nose radius for stable, high-speed turning of cast iron components; order this indexable insert via Metav Werkzeuge or request advice from the consultants at Metav Werkzeuge for optimal holder selection.

CNMG 120404 T5105 turning insert, Tungaloy — CVD-coated cemented carbide for cast iron

CNMG120404 T5105 is an ISO-format, rhombic indexable insert intended for turning applications with a focus on high-speed, wear-resistant machining of cast iron under stable conditions

• ISO CNMG geometry, 80° lead angle
• CVD-coated cemented carbide grade T5105
• 0.4 mm nose radius for stable cuts
• Double-sided chipbreaker, cylindrical hole

High-speed efficiency with wear-resistant coating

The insert is manufactured from cemented carbide and finished with a CVD-coated surface in grade T5105, a combination designed to extend tool life during aggressive cutting. This coating improves resistance to abrasive wear and thermal loading, which translates into longer intervals between indexings and fewer unscheduled tool changes. For operations where material removal rates and process reliability matter, the combination of coating and substrate delivers measurable increases in machining uptime.

Consistent geometry for secure clamping and predictable results

Produced to ISO CNMG standards, the insert's geometry ensures compatibility with holders that match the form, relief angle, tolerance class, fastening and thickness. The rhombic shape and 80° lead provide a robust cutting orientation for external and internal turning, while the cylindrical hole enables reliable screw clamping. Defined geometric parameters reduce setup variability and promote repeatable surface finish and dimensional control across series production.

Designed spec for stable cutting and easy integration

Key dimensional characteristics such as the 0.4 mm nose radius and 4.76 mm thickness support stable chip formation when the appropriate double-sided chipbreaker is selected for the workpiece and cutting conditions. The insert's layout permits cost-efficient use thanks to its reversible design, and the clearly defined relief angle of 0° supports consistent cutting behaviour in stable setups. Where finishing and consistent edge life are priorities, this insert provides a balance between edge strength and the ability to produce controlled chip flow.

FAQ

What materials is this insert suitable for?
The CNMG120404 T5105 insert is specified for high-speed machining of cast iron; the T5105 grade supports wear resistance under stable cutting conditions.

How is the insert clamped in the holder?
Clamping is achieved via the cylindrical hole and the matching screw system; compatibility requires a holder that conforms to ISO CNMG form, size and tolerance specifications.

What does the CNMG120404 designation indicate?
The designation denotes the rhombic ISO CNMG geometry with a 12 mm inscribed circle and a 0.4 mm nose radius as given in the item code.

Is the chipbreaker reversible and what is its benefit?
The insert features a double-sided chipbreaker, enabling reversible use of cutting edges and improved chip control when the breaker is matched to the workpiece and process stability.

Which geometric parameters should be checked for holder selection?
Verify form, relief (0° in this case), tolerance class, fastening method, size (12 mm I.C.) and thickness (4.76 mm) to ensure correct seating and predictable cutting performance.
