TNMG 220408 T9235 TNMG indexable insert for turning – Tungaloy

A TNMG220408 T9235 indexable insert engineered for external and internal turning, featuring a 60° triangular form and a robust edge geometry for steel machining.

• CVD-coated carbide for durable wear resistance
• Tough grade for interrupted cuts and unstable conditions
• 60° triangular form with cylindrical hole for secure clamping
• 0.8 mm corner radius for robust edge strength

Improved machining reliability under unstable conditions

The T9235 grade, applied as a CVD-coated carbide, prioritises toughness over maximum speed, making it particularly effective for turning steel where cutting conditions are intermittent or unstable. The coating increases surface hardness and reduces flank wear, while the substrate maintains toughness to resist chipping during interrupted cuts. Together with the double-sided chipbreaker, this combination provides stable chip control, reduces the risk of edge failure and supports longer uninterrupted production runs, translating into measurable gains in process reliability.

Secure fit and practical mounting for ISO-compatible holders

Designed to the ISO series, the insert’s 60° triangular form and cylindrical hole mean compatibility depends on matching holder geometry, free angle and tolerance class. The 4.76 mm thickness and 22 mm seat size are standard dimensions that facilitate selection of an appropriate clamping set, screw and support pad. The specified 0° relief angle and the 0.8 mm radius at the corner influence cutting engagement and finish; users should verify that the toolholder seat, clamp and screw conform to the ISO norms for this insert type to ensure consistent clamping and repeatable positioning.

Economic benefits through reversible indexing and edge strength

As a reversible, triangular indexable insert, the component offers multiple usable cutting edges per insert, which reduces tooling consumption per part. The robust 0.8 mm radius supports durability when generating rougher profiles, while the CVD-coated carbide balances wear resistance with impact tolerance for stops and restarts typical in interrupted turning. Choosing this insert for steel operations at moderate cutting speeds can improve uptime, lower tooling change frequency and contribute to a steady production yield with consistent surface quality.

FAQ

Which materials is this insert designed for?
The Tungaloy TNMG220408 T9235 insert is formulated primarily for machining steel, offering a tough grade suited to interrupted cuts and unstable conditions.

Can this insert be used for internal as well as external turning?
Yes, the ISO-series TNMG220408 geometry is applicable for both external and internal turning when paired with a compatible holder and clamping set.

How does the T9235 grade affect cutting parameters?
The T9235 CVD-coated carbide grade favours lower cutting speeds and offers enhanced impact resistance; machining parameters should be adjusted to prioritise stability over maximum surface speed.

What should be checked for holder compatibility?
Compatibility is determined by insert form, free angle, tolerance class, attachment style, size and thickness; ensure the toolholder matches the 60° triangular form, 4.76 mm thickness and cylindrical hole specification.

Does the insert provide good chip control for interrupted cuts?
Yes, the double-sided chipbreaker and the combination of substrate and coating support stable chip formation and evacuation in interrupted turning operations.
