SNMG120408 T5105 Tungaloy turning insert — CVD-coated carbide for high-speed cast iron machining

SNMG120408 T5105 is a square ISO turning insert designed for external and internal turning in stable conditions; suitable for high-speed machining of cast iron when combined with an appropriate holder and clamping kit.

• CVD-coated T5105 for high-speed cast iron
• Square ISO plate, cylindrical locating hole
• 0.8 mm nose radius for consistent finishes
• Double-sided chipbreaker for stable cutting

Reliable high-speed performance for cast iron components

The insert is manufactured from CVD-coated carbide in the T5105 grade, developed for wear resistance during high-speed machining of cast iron under steady, rigid conditions. This composition reduces flank wear and helps maintain cutting-edge integrity over longer cycles, which in turn supports more predictable tool-change intervals and a smoother production rhythm. For operations where machining stability is already ensured by machine and setup, the coating and substrate combination maximises productivity and repeatability.

ISO compatibility and secure clamping reduce setup time

Designed to the ISO plate form SNMG120408, the geometry, 0° relief angle, tolerance class, and cylindrical locating hole ensure compatibility with a broad range of standard toolholders. The 4.76 mm plate thickness and square shape ease seat stability and alignment in the pocket, while the standard dimensions simplify procurement and spare-part management. Clear, standardised interfaces mean less trial-and-error at installation and fewer interruptions during series production, enabling faster changeovers and better utilisation of existing turning equipment.

Consistent surface quality through controlled geometry

The 0.8 mm nose radius and double-sided chipbreaker are tuned to deliver repeatable surface finishes and reliable chip control when turning under the recommended conditions. The 90° included angle and robust cemented carbide body support dimensional consistency when finishing or semi-finishing profiles. Selecting the matching chipbreaker and grade for the specific cast-iron subtype and machining parameters will lower the risk of built-up edge and improve overall component quality, particularly where tight tolerances and surface integrity are required.

FAQ

What materials is this insert suitable for?
The SNMG120408 T5105 insert is specified for high-speed machining of cast iron using its CVD-coated carbide substrate; suitability for other materials depends on grade selection and cutting conditions.

How does the T5105 grade benefit production runs?
T5105 provides enhanced wear resistance and stable edge life in continuous, high-speed turning operations, helping to extend tool life and reduce unplanned tool changes.

Which holders are compatible with this SNMG120408 insert?
Compatibility is determined by ISO form, relief angle, plate thickness and hole style; the SNMG120408 fits standard ISO turning holders designed for square inserts with a cylindrical locating hole.

Can the insert be used on internal turning operations?
Yes — the insert form and 0.8 mm nose radius suit both external and internal turning when the correct holder geometry and cutting parameters are applied.

How does the chipbreaker design affect machining?
The double-sided chipbreaker promotes controlled chip formation and evacuation under stable cutting conditions, which supports consistent surface finish and reduces risk of chip-related interruptions.
