CNMA 120404 TH10 — Indexable turning insert, rhombic 80°, 0.4 mm radius — Tungaloy

CNMA 120404 TH10 is an ISO‑designation indexable insert for general turning; suitable for external and internal turning where low cutting forces and fine surface quality are required.

• CNMA 120404 TH10 ISO rhombic 80° geometry
• Uncoated carbide for low cutting forces
• 0.4 mm corner radius for fine finishing
• Cylindrical hole; compatible with ISO holders

Improve throughput with low cutting forces and consistent surface finish

The combination of the TH10 uncoated carbide grade and a 0.4 mm corner radius reduces cutting forces and helps achieve consistent surface quality in finishing passes. The rhombic 80° plate form provides a neutral lead that is versatile for a range of turning tasks, allowing a single insert geometry to cover external and internal operations. In practice, the uncoated cutting edge lowers friction compared with coated alternatives in non‑ferrous materials, which contributes to reduced heat generation and extended tool life under appropriate cutting conditions.

Optimised for non‑ferrous materials and precise finishing

This indexable insert is designed primarily for machining non‑ferrous materials and situations where a sharp, uncoated edge supports low feed forces and clean chips. The absence of a chipbreaker means chip formation is governed by cutting parameters and material choice; this offers better surface integrity when a controlled, continuous chip is desirable. The cylindrical hole ensures secure clamping in standard clamping systems and supports repeatable seating, which is essential for maintaining dimensional accuracy during batch production.

ISO compatibility and practical system integration for reliable production

The ISO designation and standard geometry simplify selection of compatible holders and clamping sets, while the plate thickness of 4.76 mm and 12 mm inscribed circle match common ISO toolholders. Using the correct underlay, clamp set and replacement screws completes the system: ISO conformity reduces downtime by enabling swift insert changes and predictable performance. The robust indexable format supports economical operations by permitting multiple indexed edges; for complex jobs, Metav Werkzeuge can advise on holder matching and cutting data to suit machine rigidity and workpiece material.

FAQ

Which materials are best machined with this insert? The CNMA 120404 TH10 insert and its TH10 uncoated carbide are optimised for non‑ferrous materials and finishing applications where low cutting forces and clean surfaces are required.

Is this insert compatible with standard ISO turning holders? Yes. The ISO designation CNMA120404 and the rhombic 80° plate form ensure compatibility with standard ISO holders when the holder supports the specified size, thickness and clearance angle.

Why is there no chipbreaker on this grade? The absence of a chipbreaker on this design favours finishing operations and applications where produced chips are managed by cutting conditions or downstream chip control; the TH10 edge promotes low friction and cleaner cuts.

Can the insert be used for internal turning? Yes. The 80° rhombic geometry and 0.4 mm corner radius make the insert suitable for both external and internal turning tasks, provided the holder and setup accommodate the insert dimensions.

What clamping and system components are required for safe use? Use a matching ISO external holder or boring bar, correct underlay and clamping set, plus replacement screws as needed to ensure stable seating and repeatable indexing.
