TNMG 160402 T9225 indexable turning insert – CVD-coated carbide, 0.2 mm radius (Tungaloy)

A TNMG 160402 T9225 indexable turning insert designed for external and internal turning, offering a robust universal grade for medium to heavy steel machining.

• CVD-coated carbide grade T9225
• Robust for medium to heavy steel
• Triangular 16 mm plate with 0.2 mm radius
• Double-sided chipbreaker, cylindrical hole

Proven performance where stability matters

The combination of a CVD-coated surface and cemented carbide substrate delivers a balance of wear resistance and toughness that suits varying cutting conditions. As a universal grade, T9225 is specified for medium to heavy steel machining where fluctuating engagement or light interruptions can occur; this results in fewer insert changes and a more consistent production flow. The engineered coating reduces built-up edge and supports longer tool life under cyclic loads, improving overall process efficiency and reducing downtime.

Clear guidance on compatibility and fit

Compatibility with holders depends on the insert’s form, clearance geometry and tolerance class. The triangular ISO plate (16 mm) with a cylindrical hole and 0° clearance sits securely in ISO-standard turning holders that accept TNMG-style inserts. The 60° included angle and standard thickness of 4.76 mm match many common external and internal turning toolblocks, ensuring reliable clamping and repeatable positioning for accurate diameters and surface quality.

Why the T9225 grade makes a difference in mixed conditions

The T9225 grade is formulated to offer stable chip formation and extended edge life when machining steels with varied toughness or interrupted cuts. The double-sided chipbreaker provides consistent chip control for a range of feeds, while the 0.2 mm nose radius enables fine profile detail without compromising edge strength. Together, these characteristics support cost-effective machining by reducing scrap rates and increasing the number of usable edges per insert.

Workshop advantages: handling, storage and application

A compact triangular insert simplifies inventory and tooling strategies: the 16 mm plate size and double-sided geometry maximise usable edges per insert, lowering consumable turnover. The CVD-coated carbide surface is tolerant of modest changes in cutting parameters, making it suitable for batch production or mixed-lot work. For best results, select matching holder clearance and tightening torque specified by the toolholder manufacturer; correct seating prevents chatter and preserves the insert’s wear performance.

FAQ

What materials is this insert suitable for? The TNMG 160402 T9225 indexable insert is intended primarily for medium to heavy steel machining; the T9225 grade gives robustness for mixed conditions and light interruptions.

How does the T9225 grade affect tool life? The T9225 CVD-coated carbide offers improved wear resistance and stable chip formation, which typically extends edge life and reduces the frequency of insert changes in demanding turning operations.

Is the insert compatible with standard TNMG holders? Yes — the insert conforms to ISO TNMG geometry (160402) with a triangular form, cylindrical hole and standard thickness, making it compatible with holders designed for TNMG inserts when matched by clearance and clamping specifications.

What chip control can be expected with the double-sided chipbreaker? The double-sided chipbreaker provides consistent chip formation across a range of feeds, aiding reliable evacuation during turning and reducing the risk of entanglement on interrupted cuts.

Which dimensional values are critical when selecting the holder? Key dimensions are the plate size (16 mm), thickness (4.76 mm), nose radius (0.2 mm) and included angle (60°); matching these with the holder’s seating geometry ensures correct clamping and repeatable results.
