TNMA 160404 TH03 Tungaloy indexable insert for turning, 60° triangle, 0.4 mm radius

TNMA160404 TH03 Tungaloy indexable insert for ISO‑standard turning operations, designed for low cutting forces and improved chip formation

• ISO TNMA form, 60° triangle geometry
• Sharp-edge uncoated carbide grade TH03
• 0.4 mm corner radius for fine profiling
• Compatible with cylindrical‑hole clamping systems

High efficiency for light to medium‑duty turning

The uncoated carbide composition combined with the TH03 grade provides a sharp cutting edge that reduces cutting forces and improves chip flow during external and internal turning. This results in more stable machining with lower power draw and less vibration when comparing similar geometries, making the insert well suited to jobs where minimised cutting effort and repeatable surface quality are priorities. The triangular geometry and small corner radius also support precise profile finishing and controlled transitions on small radii.

Fast tool changes and predictable mounting

Designed to the ISO standard, the triangular indexable design with a cylindrical hole enables straightforward mounting in a wide range of compatible holders and boring bars. The standardised dimensions—16 mm size and 4.76 mm thickness—allow quick replacement without special adapters, reducing downtime in production. The insert’s compatibility is determined by form, relief angle, tolerance class, clamping style, size and thickness, so choosing matched components ensures consistent repeatability and predictable tool life under stable cutting conditions.

Application guidance and material suitability

This grade is indicated for general turning where low cutting forces and good chip control are required; it is especially useful on applications that favour a sharp, uncoated edge. Given the absence of a chipbreaker, the geometry works best with appropriate feed and depth settings to promote regular chip formation. For less experienced users, selecting a matching holder and adjusting the feed to the intended surface finish will help to exploit the grade’s benefits while maintaining economical tool life.

FAQ

What types of turning are suitable for this insert?
The TNMA160404 TH03 Tungaloy indexable insert is intended for both external and internal turning where a sharp edge and low cutting forces are advantageous, providing good chip formation for light to medium cuts.

Is the insert compatible with standard ISO toolholders?
Yes, the insert follows ISO dimensions for TNMA form and is compatible with holders that accept a 60° triangular, cylindrical‑hole insert of size 16 and thickness 4.76 mm.

Does this grade include a chipbreaker for interrupted cuts?
No, the TH03 grade supplied in this insert is without a chipbreaker; machining parameters should be selected to produce regular chips and stable cutting behaviour.

How does the 0.4 mm corner radius affect edge strength and finish?
A 0.4 mm radius gives a balance between edge strength and the ability to produce finer profiles; it supports improved surface finish on contour work while maintaining adequate toughness for typical turning feeds.

Can the TH03 uncoated grade be used on hardened materials?
The TH03 uncoated carbide is optimised for low cutting forces and general turning; for hardened or exotic materials, refer to application guidelines or consult for an alternative grade optimised for higher hardness.
