TNMG 160408 T5105 – ISO turning insert, CVD-coated carbide, 0.8 mm radius (Tungaloy)

The TNMG160408 T5105 is an ISO-standard triangular turning insert engineered for high-speed turning of cast iron, featuring a double-sided chipbreaker and a cylindrical hole for secure mounting.

• ISO-standard triangular insert
• CVD-coated carbide grade T5105
• 0.8 mm corner radius for robustness
• Double-sided chipbreaker, cylindrical hole

Increased productivity through controlled chip formation

The combination of CVD-coated carbide and the T5105 wear grade is designed for high-speed machining of cast iron, providing predictable wear behaviour and reduced flank wear under stable cutting conditions. The triangular geometry with a 60° included angle and a 0.8 mm corner radius promotes a robust cutting edge that tolerates intermittent contact and vibrations better than sharper radii, which reduces part rejects and machine downtime. The double-sided chipbreaker assists in breaking long chips into manageable segments, improving process safety and facilitating swarf removal in automated production cells.

Clear guidance on compatibility and secure clamping

As an ISO-certified turning insert, compatibility with the toolholder depends on several geometric and tolerance parameters: form, clearance (fret) angle, tolerance class, fastening method, overall size and thickness. The insert’s cylindrical hole and 4.76 mm nominal thickness ensure repeatable seating and clamping in standard external holders and boring bars designed for TNMG-type inserts. For new setups, matching the holder’s pocket geometry to the insert’s form and the intended cutting conditions is essential to achieve the stated performance and to maintain stable cutting forces throughout the batch.

Reliability and cost-efficiency in series production

The T5105 grade’s CVD coating provides a hard, wear-resistant surface that extends flank life during prolonged runs, which translates into fewer indexings and lower total tooling cost per part. The triangular, double-sided design offers two usable cutting edges per side, effectively multiplying the number of cuts before disposal and improving overall tool economy. For manufacturers aiming to balance throughput and surface finish, the insert’s geometry and coating offer a compromise between aggressive material removal and consistent component quality, supporting process repeatability and reduced inspection effort.

FAQ

What materials is this insert suited for? The TNMG160408 T5105 is optimised for machining cast iron at high cutting speeds; the CVD coating and grade T5105 enhance wear resistance during such applications.

How is compatibility with toolholders ensured? Compatibility is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness; the TNMG160408’s cylindrical hole and 4.76 mm thickness suit standard TNMG toolholder pockets.

Can both sides of the insert be used? Yes, the double-sided chipbreaker design allows indexing to multiple cutting edges; this increases the number of usable edges per insert and improves tool economy.

What benefit does the CVD coating provide? The CVD coating on the T5105 grade adds a hard wear layer that reduces flank wear and maintains cutting edge integrity, resulting in longer service life during continuous high-speed turning.

Is the insert suitable for interrupted cuts? The triangular geometry and 0.8 mm corner radius provide a robust edge that manages occasional interruptions better than very small radii, though process stability remains a key factor.
