TNMG110308 T9235 Turning Insert — CVD-coated cemented carbide, 60°, Tungaloy

TNMG110308 T9235 is an ISO-standard triangular turning insert for external and internal turning, optimised for steel machining under interrupted cuts and unstable conditions

• ISO triangle insert TNMG110308 for turning
• CVD-coated cemented carbide grade T9235
• 60° geometry with 0.8 mm corner radius
• Cylindrical hole and double-sided chipbreaker

Reliable performance for unstable cutting conditions

The combination of a CVD-coated surface and a cemented carbide substrate provides a balanced wear resistance and toughness that favours productivity when machining steel at conservative speeds. In practice, the durable coating reduces flank wear and adhesion while the grade is formulated for lower cutting speeds and interrupted cuts; this results in more consistent tool life and fewer unplanned changeovers. The triangular geometry with a 60° included angle offers a robust cutting edge that tolerates variations in rigidity between holder and workpiece.

Better chip control and clearer process results

A double-sided chipbreaker on a reversible insert improves chip shaping across a range of feeds, reducing the risk of long, entangling swarf and easing evacuation from the cutting zone. The 0.8 mm corner radius balances strength and surface finish: larger radii protect the edge under load, while this specific radius still enables acceptable surface quality for many turned components. Explaining the term: a chipbreaker is a machined groove on the rake or face that actively controls chip curl and breakage, which helps stabilise cutting forces and supports predictable cycle times.

Clear compatibility and mounting information

Compatibility with toolholders is governed by form, relief angle (0°), tolerance class, fastening style, size and plate thickness; the insert thickness is 3.18 mm and the plate size is 11 mm, so matching holders and clamp kits is essential for safe, repeatable clamping. The insert is supplied with a cylindrical hole, enabling secure fixation and simple indexing; being double-sided, the insert can be rotated to present a fresh cutting edge, improving economy per insert and simplifying inventory management.

Practical choice for shop-floor reliability

Engineered for turning, this insert version performs where interrupted cuts, variable clamping and mixed-batch production demand resilience rather than maximum speed. The grade designation T9235 identifies a tougher, more ductile coating/substrate combination suited to steel workpieces and less stable set-ups; this translates to fewer broken tools and a smoother production flow. For workshops aiming to reduce downtime and increase first-pass yield, the focus on stable chip formation and consistent edge behaviour brings measurable benefits.

FAQ

What holders are compatible with this insert?
Holders that accept the TNMG form with matching size, thickness and 60° geometry are compatible; the TNMG110308 T9235 insert requires a holder that secures the plate via a cylindrical hole and supports the specified plate thickness.

Is this grade suitable for stainless steel?
The T9235 grade is optimised for steel and particularly for unstable or interrupted cuts; for stainless steel a different grade selection may be preferable depending on work-hardening behaviour.

How many cutting edges does the insert provide?
The reversible triangular format and double-sided chipbreaker give multiple usable edges per insert, improving economics versus single-edge tools when using the TNMG110308 geometry.

Does the coating help with adhesion at lower speeds?
Yes, the CVD-coated layer on the cemented carbide substrate reduces adhesion and flank wear during lower-speed machining and during interrupted cutting typical for the T9235 application.

What is the purpose of the 0.8 mm corner radius?
A 0.8 mm corner radius enhances edge strength for interrupted cuts while still permitting acceptable surface finishes on turned parts; it is a compromise between robustness and finish quality.
