TNMG 160408 T5105 triangular indexable insert for turning — Tungaloy

The TNMG160408 T5105 is an ISO-standard triangular indexable insert designed for external and internal turning, optimised for high-speed machining of cast iron under stable cutting conditions.

• CVD-coated cemented carbide T5105 for wear resistance
• Optimised for high-speed machining of cast iron
• ISO triangular insert, 60° cutting geometry
• Double-sided chipbreaker with central cylindrical hole

Consistent high-speed performance through wear-resistant coating

The insert’s CVD-coated cemented carbide grade T5105 delivers improved resistance to abrasive wear, making it suitable for sustained high cutting speeds when machining cast iron. The coating reduces flank wear under stable cutting conditions and supports a stable chip formation, which in turn helps to maintain surface finish and dimensional consistency across production runs. The double-sided design doubles usable edges per insert, lowering tooling costs per component while maintaining repeatable cutting behaviour.

Secure seating and predictable cutting geometry for faster setup

Made to the ISO specifications, the triangular geometry with a 60° cutting angle and a 0° clearance ensures predictable engagement with standard external and internal holders; compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The central cylindrical hole permits reliable registration and clamping in holders designed for indexable inserts, reducing the risk of movement during heavy cuts. The 0.8 mm corner radius balances edge strength and achievable radii on the workpiece, offering a compromise between robustness and surface definition.

Reduced downtime and improved process stability for series production

Selecting an insert with stable chip control and a wear-resistant grade helps to cut changeover frequency and supports longer uninterrupted cycles on lathes and turning centres. For production environments processing cast iron parts, the combination of a dedicated chipbreaker and a CVD-coated substrate stabilises the cutting forces and reduces the likelihood of unexpected tool failure. The result is more predictable cycle times and an improved return on tool investment through fewer stoppages and consistent part quality.

Practical selection advice and integration into existing tool systems

When integrating this ISO triangular insert into a tooling system, match the chipbreaker and grade to the workpiece and machining stability: choose the chip control suited to interrupted or continuous cuts and confirm the holder accepts a TNMG 160408 form with a plate thickness of 4.76 mm. The double-sided construction provides economical edge rotation; where surface finish is critical, opt for stable clamping and appropriate feed and speed adjustments. Operators and process planners will benefit from verifying holder tolerance class and fastening compatibility before series production.

FAQ

What materials is this insert designed to machine?
The TNMG160408 T5105 is engineered primarily for cast iron machining; the CVD-coated cemented carbide grade T5105 provides abrasion resistance suited to high-speed cast iron cutting.

How is the insert clamped in a holder?
The triangular insert locates on the seat via its cylindrical hole and is clamped according to the holder’s form, tolerance and fastening method; compatibility depends on matching form, clearance angle and plate thickness.

Can the insert be indexed to use multiple edges?
Yes, the insert is double-sided, allowing rotation to fresh cutting edges and thereby extending the service life per insert in serial production.

What does the 0.8 mm corner radius mean for finishing?
A 0.8 mm corner radius offers increased edge strength with moderate roundness on the workpiece; it provides a balance between robustness and the achievable surface finish.

Is the grade suitable for interrupted cuts?
The T5105 grade is optimised for high-speed conditions and stable cutting. For heavily interrupted cuts, select a chipbreaker and holder configuration that prioritises edge strength and secure clamping.
