*Double-sided insert with 0.8 mm corner radius
*Compatible with standard external/internal holders

Consistent chip control for variable cutting conditions

The CVD-coated composition and T9225 grade deliver a balance of hardness and toughness that stabilises chip formation under changing loads. The triangular 60° geometry provides multiple cutting edges and a versatile cutting direction, while the double-sided design maximises usable edges for efficient turnarounds. This configuration is especially suited to operations where intermittent cuts or varying depths require a material that resists chipping without compromising cutting capacity.

Extended tool life through a robust grade and geometry

A thicker plate and a compact corner radius combine to reduce local stress at the cutting edge, which translates into longer in-service life and fewer indexings. The insert’s 0.8 mm corner radius promotes edge strength for heavier cuts, and the substantial plate thickness of 4.76 mm supports stable clamping and heat distribution. Together, these features reduce flank wear and enable predictable intervals between tool changes, supporting improved uptime and lower tool consumption per component.

Predictable fit and fast changeover in ISO systems

Compatibility with toolholders is defined by geometry, clearance angle, tolerance class, fastening method, size and thickness; the ISO TNMG160408 form ensures straightforward interchangeability in standard holders when those criteria are matched. The insert features a cylindrical hole for secure mounting and a 0° clearance angle that suits many conventional external and internal turning set-ups. Clear identification of form and size simplifies tool management and reduces the risk of mismatched assemblies during production planning.

Practical guidance for steel turning applications

Designed as a universal, robust cutting grade for medium to heavy steel machining, this insert performs well where occasional interruptions or fluctuating cutting conditions demand extra toughness. Select a chipbreaker and holder arrangement appropriate to the operation’s stability and feed rate to get the best surface finish with a low risk of edge failure. For complex materials or critical surface requirements, pairing the insert with a suitable holder and clamping kit will enhance process reliability and repeatability.

FAQ

What materials is this insert best suited for?
The insert is specified as grade T9225, a CVD-coated carbide designed for robust, universal use in medium to heavy steel turning applications and is manufactured by Tungaloy.

Is the insert indexable on both sides?
Yes, the indexable cutting insert is double-sided, providing multiple edges to extend usable life and reduce changeover frequency.

What is the corner radius and how does it affect performance?
The insert has a 0.8 mm corner radius, which increases edge strength for heavier cuts and helps prevent chipping during intermittent or unstable cutting conditions.

Which holders are compatible with the TNMG160408 form?
Compatibility is achieved with holders that accept the ISO TNMG160408 geometry, matching size, thickness and fastening type; the insert’s cylindrical hole and ISO form ensure reliable mounting in standard external and internal turning holders.

Does the coating improve wear resistance?
The CVD coating on this carbide insert enhances wear resistance at elevated temperatures and supports stable cutting performance, contributing to predictable tool life in demanding steel turning tasks.
