SNMG120420 T5115 Tungaloy turning insert — CVD-coated carbide, ISO SNMG square insert

The SNMG120420 T5115 Tungaloy turning insert is an ISO-standard square indexable insert for external and internal turning, designed for productive machining of cast iron with a balanced mix of wear resistance and edge stability.

• CVD-coated carbide T5115 for cast-iron machining
• ISO SNMG120420 square geometry, 90° included angle
• Double-sided chipbreaker with cylindrical hole

Reliable wear resistance for cast-iron machining

The combination of a CVD coating and a carbide substrate in grade T5115 delivers a balanced performance profile: enhanced wear resistance together with maintained edge stability during interrupted and continuous cuts. The CVD process deposits hard layers that protect the substrate from abrasive wear, while the carbide core preserves toughness. This mix is particularly useful when machining grey or nodular cast iron, where fluctuating cutting conditions demand both abrasion resistance and a stable cutting edge. The insert is produced to ISO SNMG120420 dimensions to ensure compatibility with standard square indexable holders and mounting systems.

Higher productivity through consistent chip control and robustness

Chip control and repeatable tool life are central to productive turning. The insert’s double-sided chipbreaker promotes chip control across a range of depths of cut, reducing the risk of entanglement and stabilising cutting forces. With a 2 mm corner radius and a 90° included angle, the geometry supports higher radial engagement and improved rigidity, which can shorten cycle times on suitable machines. The neutral 0° clearance angle contributes to predictable cutting behaviour, while the insert’s dimensions — 12 mm inscribed size and 4.76 mm thickness — provide a robust platform for medium and heavy turning operations.

Compatibility, handling and recommended use

Compatibility with a given holder is defined by form, relief angle, tolerance class, fastening and the insert’s size and thickness; the system typically consists of the indexable insert, a matching external holder or boring bar, a shim/clamping set and replacement screws. The SNMG design with a cylindrical hole permits secure fastening and straightforward indexing of the double-sided cutting edges, enabling economical use of both faces. Selection of the chipbreaker and grade should follow the workpiece material, machining strategy and machine/tooling stability — for less rigid setups choose lighter parameters and finer chipbreakers; for stable assemblies, the T5115 grade and its chipformer enable productive material removal while preserving edge life.

FAQ

Is this insert suitable for cast-iron machining?
The SNMG120420 T5115 Tungaloy turning insert (SKU 6852996-Tungaloy) is specifically offered as a universal grade for cast-iron work, combining T5115’s wear resistance with a chipformer suited to typical cast-iron chips.

What advantages does the T5115 grade provide?
T5115 is a CVD-coated carbide grade that provides a balanced compromise between abrasion resistance and edge stability; this supports longer tool life under the varied conditions encountered in cast-iron turning.

How is holder compatibility determined?
Compatibility is determined by the insert’s form, relief (clearance) angle, tolerance class, fastening method, size and thickness — the SNMG120420 follows ISO dimensions to match standard square turning holders.

Can this insert be used for finishing passes?
The insert’s 2 mm corner radius and robust geometry make it well suited to medium and rough turning; for fine finishing a smaller radius and a dedicated finishing grade or geometry may produce a better surface finish.

How does the double-sided chipbreaker affect handling?
The double-sided chipbreaker allows both faces to be indexed, improving economy; the cylindrical hole and standard ISO form enable secure clamping and straightforward replacement in compatible holders.
