TNMG 160404 T9225 — Turning indexable insert by Tungaloy, CVD-coated carbide, 0.4 mm radius

A TNMG160404 T9225 triangular indexable insert for ISO-spec turning, designed as a robust universal grade for medium to heavy steel machining.

• CVD-coated carbide T9225 for robust steel turning
• Triangular TNMG form with 60° cutting angle
• 0.4 mm nose radius for precise profiling
• Double-sided chipbreaker with cylindrical hole

Consistent edge life through CVD-coated carbide technology

The CVD-coated carbide composition of this insert combines a wear-resistant coating with a tough substrate, delivering a balance between hardness and fracture resistance. As a T9225 universal grade, it is intended for medium to heavy steel cutting where variable cutting forces or lightly interrupted cuts demand additional toughness. The coating improves abrasion resistance at higher temperatures while the cemented carbide core maintains edge stability, so the tool life is extended and change intervals are more predictable — a clear advantage for batch production and mixed-run shop floors.

Geometry optimised for turning accuracy and predictable results

The insert’s triangular TNMG geometry provides a 60° main cutting angle that is standard for many external and internal turning operations, giving reliable approach angles and fixture options. The specified 0.4 mm nose radius supports fine profile work and repeatable surface finishes while still permitting adequate strength at the cutting edge. The plate is supplied with a cylindrical hole, enabling secure clamping in ISO holders; overall compatibility depends on the insert form, clearance angle, tolerance class, attachment method, size and thickness. This standardisation simplifies tool inventory and reduces setup time across different machines.

Productivity benefits from chip control and plate reversibility

Equipped with a double-sided chipbreaker, the insert offers two cutting edges per indexation, improving uptime and cost-efficiency per edge. The chipbreaker design supports stable chip formation on typical steel grades, contributing to consistent surface quality and reduced risk of edge damage under variable conditions. For turning lines where throughput and repeatability matter, this combination of geometry and chip control increases productivity while maintaining acceptable surface integrity.

Practical selection and shop-floor handling tips

As an ISO-standard turning insert, the component integrates into common holder systems; selection of the correct chipbreaker and grade should match the workpiece material, the machining strategy and the machine-tool rigidity. For roughing heavy sections choose the robust grade and a chipbreaker suited to large volume removal; for finishing, the smaller nose radius and refined chip control yield better surface results. System components typically include an appropriate external holder or boring bar, a shim/clamp set and replacement screws — ensure holder compatibility by checking form, clearance angle and tolerance class before installation.

FAQ

Which materials is this insert best suited for? The TNMG160404 T9225 insert from Tungaloy is designed as a robust universal grade for medium to heavy steel machining and copes well with variable engagement conditions and light interruptions.

What does the designation 160404 indicate for the geometry? The code refers to the ISO geometry: 16 mm inscribed circle, 04 edge length relating to the insert family and a 0.4 mm corner radius; this helps in selecting matching ISO holders and clamping systems.

Is the insert reversible and how many cutting edges are available? This triangular TNMG plate is double-sided with a chipbreaker, offering two usable cutting edges per side and therefore multiple indexations before replacement.

How is holder compatibility ensured for this indexable insert? Compatibility depends on the insert form, clearance angle, tolerance class, attachment method, size and thickness; the TNMG160404 conforms to ISO specifications and fits matching ISO holders and boring bars when these parameters align.

What advantage does the T9225 grade provide compared with other grades? The T9225 CVD-coated grade balances wear resistance and toughness, providing stable chip formation and good edge life in medium to heavy steel turning, particularly when cuts are variable or lightly interrupted.
