SNMG120404 T5115 SNMG — CVD-coated indexable insert for turning by Tungaloy

The SNMG120404 T5115 SNMG is an ISO-format indexable insert designed for general turning operations, offering a universal grade optimised for cast iron machining.

• CVD-coated cemented carbide for cast iron
• Double-sided chipbreaker
• 0.4 mm corner radius
• Square plate, 12 mm size

Consistent performance for cast-iron turning

The T5115 grade combines a CVD-coated surface with a cemented carbide substrate to strike a balance between wear resistance and edge stability. This composition reduces flank wear during interrupted cuts and long runs, resulting in fewer insert changes and a more predictable tool life. In practical terms, the material pairing supports steady production outputs when machining grey or nodular cast iron, where abrasion and brittle fracture of the workpiece demand robust edge behaviour.

Geometry that supports reliable surface finish

The square plate geometry with a 0.4 mm corner radius and a 90° included angle provides a stable cutting edge that improves dimensional control on external and internal profiles. The slightly rounded corner helps distribute cutting forces and reduces the likelihood of chipping when entering and exiting cuts. Paired with the double-sided chipbreaker, the insert promotes an even surface texture and repeatable results across serial components, which is particularly valuable for batch production and parts with tight tolerances.

Secure mounting and broad compatibility

Compatibility with toolholders is determined by form, relief angle, tolerance class, fastening and plate thickness; the SNMG120404 conforms to ISO form and size standards to ensure straightforward replacement in compliant holders. The plate’s 4.76 mm thickness and cylindrical hole enable secure clamping, while standard tolerances simplify toolset logistics. This makes integration into existing tool systems efficient and minimises setup time during tool changes.

Practical chip control and machining economy

The double-sided chipbreaker is engineered for stable chip formation when turning cast iron, reducing cutting interruptions and improving coolant interaction. Stable chip control lowers scrap risk and shortens cycle times, delivering a tangible process efficiency gain. For customers measuring productivity, these inserts contribute to improved uptime and reduced total machining cost per part when used with suitable feeds and speeds.

Coating technology and edge durability

The CVD coating on the T5115 grade enhances resistance to abrasive wear and thermal softening at the cutting edge, extending useful life in demanding cast-iron applications. The coating also helps preserve the cutting geometry, which supports consistent dimensional quality over longer tool life. When combined with appropriate machining parameters, the coating assists in maintaining a sharp, stable edge under cyclic loads.

Recommended applications and tips for best results

Designed for external and internal turning, this ISO-format insert is best used with a holder that matches the plate’s form and tolerance class. Select the chipbreaker and insert grade according to the specific cast-iron variant and the rigidity of the setup. For interrupted or heavy cuts, consider more conservative feeds and finishing passes to take full advantage of the insert’s edge stability. The SNMG120404 T5115 insert is particularly suited to series production where repeatability and predictable tool replacement intervals are priorities.
