CNMG 120404 TH10 Tungaloy indexable insert for turning — ISO rhombic geometry, 0.4 mm radius

CNMG 120404 TH10 Tungaloy indexable insert offers a compact solution for general turning tasks, designed for reliable performance in a wide range of non-ferrous applications.

• ISO‑standard rhombic insert, size 12
• Uncoated carbide grade TH10 for low cutting forces
• 0.4 mm corner radius for precise surface finish
• Double‑sided chipbreaker for consistent chip control
• Cylindrical hole for secure screw mounting

Consistent cutting performance with an ISO‑conforming design

The CNMG120404 TH10 insert combines an ISO‑standard outline with a rhombic geometry that supports versatile turning operations. The uncoated carbide composition (grade TH10) is formulated to provide low cutting forces, which reduces spindle load and supports stable cutting at modest feeds. Reduced cutting effort contributes directly to longer tool life in many non-ferrous machining tasks and helps to maintain dimensional stability on the workpiece. The indexable nature of the plate enables quick orientation changes and efficient use of the cutting edge, supporting uninterrupted production cycles and predictable process planning.

Geometry and edge design that improve surface quality

The plate’s 0.4 mm corner radius and double‑sided chipbreaker are engineered to balance cutting strength with finish quality. A small corner radius like 0.4 mm enables finer external radii and improved surface finish on light‑duty turning and semi‑finishing operations. The double‑sided chipbreaker enhances chip segmentation on both edges, aiding consistent evacuation when machining short and medium chips. The insert’s 0° relief angle and rhombic shape influence the effective rake and engagement, so the insert can be selected to favour either surface finish or heavier material removal depending on the holder and cutting conditions chosen.

Practical compatibility and application guidance for tool systems

Compatibility with holders is determined by form, clearance angle, tolerance class, fixing method, size and thickness; the CNMG120404 is supplied with a cylindrical hole for standard screw clamping to most ISO‑compatible external holders and boring bars. The plate thickness of 4.76 mm and the standardised insert size provide straightforward replacement in existing tool rigs. The grade TH10 is a sharp, uncoated universal grade recommended primarily for non‑ferrous materials, where a clean cutting edge helps to avoid built‑up edge and secures superior surface finishes. For system assembly, pair the insert with a correctly matched external holder, backing pad and replacement screws specified for the holder series to ensure repeatable clamping and positional accuracy.

FAQ

What materials is this insert best suited for? The CNMG 120404 TH10 Tungaloy insert is optimised for non‑ferrous materials and applications where an uncoated, sharp carbide edge supports low cutting forces and clean surfaces.

How is the insert mounted in a toolholder? Mounting is by conventional screw clamping: the plate is supplied with a cylindrical hole for secure fixing to ISO‑compatible external holders and boring bars.

Does the corner radius affect finishing capability? Yes — the 0.4 mm corner radius supports finer surface finishes and more accurate external profiles while maintaining adequate edge strength for light to moderate turning.

Is this a single‑edge or multi‑edge solution? The plate is double‑sided and indexable, offering two usable cutting edges per side and permitting economical re‑indexing to renew the cutting edge.

What should be checked for holder compatibility? Compatibility is determined by the insert form, clearance angle, tolerance class, fixing method, size and thickness; matching these parameters ensures correct seating and repeatable performance.
