TNMG160412 T5115 — ISO turning indexable insert, CVD-coated carbide (Tungaloy)

The TNMG160412 T5115 is an ISO-standard triangular indexable insert engineered for external and internal turning of cast iron, combining a balanced wear resistance and edge stability for productive machining.

• TNMG 160412 profile, 60° cutting geometry
• CVD-coated carbide T5115 for cast iron
• 1.2 mm corner radius for stable cutting
• Double-sided chipbreaker, cylindrical hole

Durable grade for dependable cast-iron turning

The CVD-coated cemented carbide grade T5115 offers a balanced mix of wear resistance and edge stability, which translates into longer tool life and fewer interruptions to the machining cycle. As a ISO-compliant insert, the component supports standardised toolholders and simplifies tool inventory. The coating reduces abrasive wear on grey and nodular cast iron, while the substrate preserves edge geometry under interrupted cuts, delivering consistent surface quality and predictable regrinding intervals.

Geometry and clamping that ensure process reliability

Featuring a triangular insert shape with a 60° approach angle and a 1.2 mm corner radius, this insert provides a compromise between edge strength and dimensional control. The 4.76 mm plate thickness and the cylindrical hole permit secure clamping in compatible holders, while the 0° relief angle supports neutral cutting conditions for many turning operations. These dimensional and geometric parameters are decisive for achieving stable cutting forces and reliable chip formation when paired with an appropriate holder and clamping set.

Practical advantages in workshop use and selection

The double-sided chipbreaker construction enables indexation to fresh cutting edges, improving uptime and reducing tooling cost per part. As part of a system comprising the ISO insert, matching external holder or boring bar, and standard clamping components, the insert should be selected together with the chipbreaker and grade according to workpiece material and machine stability. Compatibility depends on form, relief angle, tolerance class, fastening type, size and thickness, so a coordinated selection ensures efficient chip control and predictable tool life.

FAQ

What materials is this insert designed for? The TNMG160412 T5115 by Tungaloy is a universal grade optimised for machining cast iron, offering a balanced combination of wear resistance and edge stability for those materials.

How does the insert secure to the holder? The insert features a cylindrical hole for positive clamping; secure fixing requires a compatible holder and correct fastening that match the TNMG160412 form, size and thickness.

What benefit does the 1.2 mm corner radius provide? A 1.2 mm corner radius increases edge robustness under intermittent cuts and improves dimensional stability compared with finer radii, helping to extend the effective life of the turning edge.

Is the chip control suitable for interrupted cuts? The double-sided chipbreaker on this indexable insert aids chip formation and evacuation; combined with the T5115 grade, it supports stable performance even in semi-stable cutting conditions typical for cast iron turning.

How should the insert be matched to a toolholder? Compatibility requires matching form, relief angle, tolerance class, fastening method, size and thickness; the TNMG160412 designation and the ISO model series simplify selection for standardised holders.
