TNMG 160412 T9215 TNMG Turning Insert for Turning – Tungaloy

TNMG160412 T9215 is a triangular ISO turning insert designed for medium-steel machining, offering CVD-coated carbide performance and reliable stability in continuous to lightly interrupted cuts.

• CVD-coated carbide grade T9215
• Triangular 60° insert, size 16
• 1.2 mm corner radius for enhanced stability
• Double-sided chipbreaker with cylindrical hole

High productivity for medium-steel turning

The CVD-coated carbide T9215 grade is engineered as a first choice for medium-steel applications, combining wear resistance with fracture toughness to sustain productive cutting. The 60° geometry and triangular form ensure efficient engagement on external and internal turning operations, while the 1.2 mm corner radius improves edge strength and helps maintain process stability under continuous and light interrupted cuts. This results in longer tool life and more consistent component quality, which benefits cycle-time sensitive production environments.

Precise compatibility and system integration

As an ISO-standardised turning insert, the TNMG160412 interfaces with holders according to form, clearance angle, tolerance class, fastening method, size and thickness. The system normally comprises an insert, a matching external holder or boring bar, a shim/clamping set and replacement screws; this modular approach enables quick replacement and repeatable set-up accuracy. The insert’s cylindrical hole and double-sided design allow economical index changes and minimise downtime, while holder compatibility ensures correct seating and optimal cutting geometry.

Durability, chips and predictable performance

The insert’s double-sided chipbreaker design promotes reliable chip control when paired with appropriate feed and speed settings for steel. The CVD layer on cemented carbide combines a hard, wear-resistant surface with a tough substrate beneath, reducing flank wear and the risk of edge chipping. For shops aiming at consistent surface finish and high throughput, this balance between hardness and toughness provides measurable savings in tool consumption and rework.

Practical considerations for selection and use

Select the chipbreaker and grade to match workpiece material, machining type and rigidity. Where interrupted cuts or heavy roughing are frequent, the corner radius 1.2 mm and the robust grade help avoid premature edge failure. For finishing passes, adjusting feed and spindle speed to exploit the insert’s geometry will improve surface integrity. Remember that insert compatibility is determined by a set of mechanical criteria—using the correct seat and clamping components is essential for repeatable results.

FAQ

What materials is this insert suited for?
The TNMG160412 T9215 insert is specified for medium-steel machining; the CVD-coated T9215 grade balances wear resistance and toughness for productive steel turning.

Is the insert reversible and indexable?
Yes, the triangular TNMG form is double-sided and indexable, allowing multiple index positions to be used before replacement, which reduces tooling costs per part.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and size; the TNMG160412 conforms to ISO standards for turning inserts and fits matching TNMG-rated holders.

How does the T9215 grade affect cutting parameters?
T9215’s wear resistance and fracture toughness permit higher cutting speeds and consistent performance in continuous to lightly interrupted cuts; final cutting data should be adjusted to machine rigidity and workpiece conditions.

Does the insert include a chipbreaker and what is its purpose?
The insert features a double-sided chipbreaker designed to control chip formation and evacuation, improving surface finish and process reliability in turning operations.
