CNMG120404 TH10 – CNMG turning indexable insert (rhombic, 0° relief) by Tungaloy

A CNMG120404 TH10 insert for ISO-standard turning applications, optimised for non‑ferrous materials and jobs that demand low cutting forces and fine surface quality.

• Uncoated carbide TH10 grade
• Rhombic CNMG geometry, ISO 120404
• 0.4 mm nose radius for fine finishes
• Double-sided chipbreaker, economical use

Consistent cutting performance for turning operations

The ISO-format indexable insert is designed for stable, repeatable turning tasks on lathes and turning centres. The uncoated carbide substrate in TH10 delivers a sharp, low-friction cutting edge that reduces cutting forces and helps achieve a clean surface on non‑ferrous workpieces. The rhombic CNMG geometry with an 80° included angle combines rigidity with accessible cutting edges, making the insert suitable for both external and internal turning when matched with an appropriate holder. The 0° relief should be considered during holder selection, as compatibility with the toolholder depends on geometry, tolerance class and fastening method.

Economical edge life and straightforward re-indexing

A double-sided chipbreaker offers multiple usable edges per insert; this lowers tooling cost per cutting edge and simplifies changeover. For applications where low cutting forces are essential—such as machining brass, aluminium alloys and other non‑ferrous materials—the uncoated TH10 grade helps avoid built‑up edge and promotes consistent chip formation. The 0.4 mm nose radius balances strength and surface finish: small radii improve detail and leave finer finishes, while the CNMG shape ensures sufficient support for moderate radial depths of cut.

Practical guidance for selection and use

Compatibility with the holder is determined by form, relief angle, tolerance class, fastening and plate thickness. The insert’s 4.76 mm plate thickness and 12 mm inscribed circle must match the seat and clamp of the selected cartridge or boring bar. The cylindrical centre hole enables secure clamping and precise positioning. Choose the chipbreaker variant that fits the workpiece material and the expected level of machining stability; the chip control influences surface quality and cycle time as much as substrate choice.

Application scope and recommended setups

Designed within the ISO turning insert system, this rhombic insert performs well in operations requiring a sharp, uncoated cutting edge. Typical uses include short‑chipping non‑ferrous components and finishing passes where low cutting force and a tidy surface are priorities. For roughing or highly interrupted cuts, consider a geometry and grade combination optimised for increased edge strength. When in doubt, reference the ISO series system and the insert’s measured data—12 mm inscribed circle, 4.76 mm thickness, 0.4 mm nose radius, 80° included angle—to match the correct holder and clamping set.

FAQ

What materials are best machined with this insert?
The CNMG120404 TH10 insert from Tungaloy is intended primarily for non‑ferrous materials and applications where a sharp, uncoated edge reduces cutting forces and improves surface finish.

How does the double-sided chipbreaker affect tool life?
A double-sided chipbreaker provides additional usable cutting edges, allowing re‑indexing to a fresh edge and lowering the cost per effective edge while maintaining effective chip control.

Is the insert compatible with standard ISO CNMG holders?
Compatibility with ISO CNMG holders depends on form, relief angle, tolerance class, fastening and plate thickness; the insert’s ISO designation and dimensions (12 mm IC, 4.76 mm thickness) should be matched to the holder seat.

What does a 0° relief angle mean for setup?
A 0° relief denotes a neutral relief geometry that must be matched to the holder geometry; it can affect cutting contact and requires correct seating and clamping to ensure proper cutting conditions.

How should the 0.4 mm nose radius be used in finishing?
The 0.4 mm radius offers a balance between edge strength and surface finish, making it suitable for fine finishing passes where a controlled surface texture is required.
