TNMG160408 T9225 turning insert — CVD-coated carbide, 0.8 mm corner radius (Tungaloy)

A TNMG160408 T9225 indexable turning insert designed for robust medium to heavy steel turning, offering a balance of toughness and wear resistance for variable cutting conditions

• CVD-coated carbide for enhanced wear resistance
• Universal grade T9225 for medium-heavy steel
• 0.8 mm corner radius for robust edge strength
• ISO TNMG triangular insert, double-sided chipbreaker

Higher productivity through material and grade selection

The insert’s CVD coating and T9225 grade are selected to extend tool life under demanding loads while preserving cutting-edge stability. This combination translates into fewer insert changes and more productive machining cycles when performing external and internal turning operations. The geological balance of hardness and toughness in the substrate supports reliable performance during light interruptions or variable engagement, which helps maintain consistent cycle times and lowers per-part tooling costs.

Faster set-up and reliable clamping for stable cuts

The triangular TNMG geometry with a 60° included angle and 0.8 mm corner radius delivers predictable tool contact and a sturdy cutting edge that resists chipping. The insert’s double-sided configuration and the cylindrical locating hole allow for rapid indexing and secure clamping in ISO-compatible holders, reducing downtime for regrinds and replacements. These mechanical details contribute to stable cutting forces and improved surface finish with minimal operator intervention.

Application guidance and system integration for turning work

Designed for turning applications, this carbide insert is suited to an array of holders and tool systems where ISO dimensions and clamping standards are observed. The insert’s geometry and chipbreaker design support effective chip control during medium to heavy steel machining, while the coating enhances thermal resistance at elevated cutting speeds. Consider the full system — holder, shim, clamping set and screws — to ensure optimal torque transmission and consistent axial clearance for long-term repeatability.

FAQ

What materials is this insert intended for?
The TNMG160408 T9225 insert is specified for medium to heavy steel machining; the T9225 grade provides toughness for variable engagement and interrupted cuts.

How does the T9225 grade affect tool life?
Tungaloy’s T9225 grade, combined with a CVD coating, improves wear resistance and edge stability, which typically results in longer tool life and fewer indexings on the insert.

Is the insert indexable and how many cutting edges are available?
The triangular TNMG geometry is double-sided and indexable; indexing frequency depends on the chosen clamping strategy and toolholder compatibility.

Which holder features must be checked for compatibility?
Compatibility is determined by the insert form, clearance angle, tolerance class, clamping method, size and thickness — matching the ISO TNMG dimensions ensures proper fit and secure clamping.

What advantage does the 0.8 mm corner radius provide?
A 0.8 mm corner radius offers a compromise between edge strength and surface finish, improving resistance to chipping during heavier cuts while still allowing acceptable surface quality.
