TNMG220412 T5105 ISO turning insert — CVD-coated carbide, double-sided chipbreaker (Tungaloy)

The TNMG220412 T5105 is an ISO-standard triangular turning insert designed for external and internal turning, optimised for high-speed machining of cast iron where stability and consistent wear resistance are required

• CVD-coated carbide T5105 for cast iron
• ISO TNMG220412 triangular insert
• Double-sided chipbreaker for cost efficiency
• 1.2 mm corner radius for robust finish

Precision and productivity for high-speed cast-iron turning

The combination of a CVD-coated surface and a wear-resistant carbide substrate provides the primary advantage: increased cutting speeds with lower flank wear. In stable machining conditions, the T5105 grade maintains edge integrity over longer cycles, which directly improves productivity and reduces the frequency of insert changes. Where cycle time and predictable performance matter, this geometry supports efficient chip formation and controlled heat distribution, so fewer interruptions occur during bar or face turning operations.

Compatibility and reduced setup time through ISO conformity

Being an ISO-standard insert, the plate mates with holders according to its form, clearance angle, tolerance class, fixation, size and thickness, which simplifies procurement and inventory management. The triangular shape with a cylindrical hole and a thickness of 4.76 mm enables secure clamping in a broad range of external holders and boring bars. The double-sided design halves the effective tooling cost per usable edge and shortens downtime for re-indexing, while the standardised dimensions make replacement straightforward during scheduled maintenance.

Consistent surface finish and predictable tool life

A 1.2 mm corner radius and the integrated double-sided chipbreaker deliver a balance between edge strength and surface quality. The small radius supports stable cutting with good finish on interrupted cuts typical in cast-iron components, while the chipbreaker aids reliable chip control to prevent recutting. With a 0° clearance angle and the 60° included angle, the insert offers a stable bearing surface when mounted correctly. For finishing passes or light to medium roughing under steady conditions, this combination gives reproducible results and helps achieve target tolerances with fewer adjustments.

FAQ

Which materials is this insert intended for? The TNMG220412 T5105 insert is optimised for machining cast iron; the CVD-coated carbide grade provides wear resistance suited to high-speed finishing in stable conditions.

Is the insert reversible and how many cutting edges are available? The triangular TNMG geometry with a double-sided chipbreaker offers multiple usable edges; the TNMG220412 T5105 can be indexed to use the other cutting edges, improving cost efficiency per edge.

How does the 1.2 mm corner radius affect performance? A 1.2 mm corner radius increases edge strength and contributes to a consistent surface finish, particularly on interrupted cuts common in external turning of cast iron.

What holder compatibility should be checked before ordering? Compatibility is determined by form, clearance angle, tolerance class, fixation, size and thickness; confirm the holder accepts ISO TNMG220412 dimensions to ensure secure clamping and correct seating.

Can the TNMG220412 T5105 be used for internal turning? Yes, the insert is suitable for both external and internal turning when mounted in the appropriate boring bar or internal holder designed for ISO TNMG plates.
