TNMG 110308 T9225 turning insert (TNMG110308) — CVD-coated carbide, 0.8 mm nose radius (Tungaloy)

The TNMG110308 T9225 is a triangular ISO turning insert designed for external and internal turning, offering a robust universal grade for varying cutting conditions in steel machining.

• CVD-coated carbide for robust cutting
• 0.8 mm nose radius for reliable finishes
• ISO‑standard TNMG110308 form with 0° relief
• Double-sided chipbreaker and cylindrical hole

Consistent productivity for medium‑to‑heavy steel turning

The insert is based on a robust universal grade (T9225) and a CVD-coated carbide substrate engineered for stability under varying engagement conditions. That combination increases process reliability and extends tool life during interrupted cuts or mixed finishing and semi‑roughing passes. By selecting a grade intended for medium‑to‑heavy steel work, manufacturers benefit from fewer tool changes and more predictable cycle times, enhancing throughput on turning operations.

Precision profile and surface quality from the 0.8 mm nose

A 0.8 mm nose radius balances cutting strength with achievable surface finish: the slightly rounded tip reduces chipping risk while still enabling good surface results on external and internal contours. The insert’s 0° relief and 60° cutting angle provide a clear geometry description for toolpath programming and holder selection, and explain why the component is suitable for many common turning programmes. For less experienced operators, the geometry reduces sensitivity to minor setup variances, improving first‑pass quality.

Compatibility and secure clamping for ISO tool systems

The part is an ISO‑standard TNMG110308 insert with a triangular form and a cylindrical hole, which ensures compatibility with a wide range of external holders and boring bars that accept TNMG inserts. Compatibility depends on form, relief angle, tolerance class, attachment method, size and thickness: using the correct holder and clamp set secures repeatable positioning and safe indexable performance. The double‑sided configuration offers economical indexing, halving tooling cost per usable edge.

Practical machining guidance and material performance

The T9225 grade is intended as a general‑purpose solution where slightly increased toughness is needed for variable cut conditions; it performs well where intermittent cutting or modest interruptions occur. For steel applications, select cutting data that favour the grade’s balance of hardness and toughness: moderate cutting speeds with appropriate feed and depth of cut will exploit the CVD coating for improved wear resistance while preserving the cutting edge. When in doubt about recommended parameters or holder matching, technical advice is available to align the insert with specific machine and workpiece setups.

FAQ

What materials is this insert suitable for?
The TNMG110308 T9225 insert is specified for medium‑to‑heavy steel turning; the T9225 grade and CVD‑coating provide wear resistance and toughness suited to variable cutting conditions in steel.

Can this insert be used for internal turning or only external work?
The triangular ISO TNMG110308 geometry with a cylindrical hole allows use in both external holders and appropriate boring bars, so it is suitable for internal as well as external turning operations when mounted in a compatible holder.

How many cutting edges are available per insert?
This indexable insert is double‑sided with a triangular form, providing multiple usable cutting edges before regrinding or replacement is required; the exact number of edges depends on indexing and wear.

What does the 0.8 mm nose radius mean for surface finish?
A 0.8 mm nose radius offers a compromise between edge strength and surface quality: it reduces edge chipping risk while delivering good surface finishes on profiles and external contours during standard finishing passes.

Which holders are compatible with the TNMG110308 form?
Compatibility is determined by form, relief angle, tolerance class, attachment method, size and thickness; holders designed for TNMG110308 inserts and matching the 3.18 mm thickness and 11 mm inscribed circle will provide secure clamping and accurate positioning.
