SNMG 120408 T5125 Turning insert by Tungaloy — CVD-coated carbide, 0.8 mm corner radius

A SNMG 120408 T5125 square ISO turning insert for external and internal turning, optimised for interrupted cuts and less stable machining conditions.

• CVD-coated carbide grade T5125
• Suited to interrupted cuts in cast iron
• Square ISO SNMG with cylindrical hole
• Double-sided insert for economical indexation

Consistent performance where interruptions occur

The combination of CVD-coated carbide and the T5125 grade delivers a balanced mix of toughness and wear resistance. This insert is engineered for interrupted cuts, where sudden engagement with the material can lead to edge chipping; the tougher grade reduces the risk of fracture and supports stable chip formation. As a result, tool life is extended and interruptions to production are minimised, which translates into fewer tool changes and a lower cost per cutting edge.

Easy integration into ISO toolholding systems

Produced to ISO dimensions, the square geometry and cylindrical hole ensure secure clamping in matching holders. The insert’s 0° relief angle and defined thickness (4.76 mm) create predictable seating and repeatable positioning; this reduces setup time and helps maintain consistent part tolerances. Using an ISO-compliant insert such as this simplifies inventory and compatibility across a workshop with standardised holders and clamping kits.

Cost-efficiency and process security in daily production

The double-sided design offers two usable cutting edges per index, improving economy without sacrificing performance. The modest 0.8 mm corner radius provides a balance between edge strength and surface finish, while the square form with a 90° cutting geometry suits common turning tasks. For shops facing variable stability or frequent interrupted cuts, this insert delivers reliable results and reduced scrap rates, supporting more predictable cycle times and overall process security.

FAQ

Which materials is this insert best suited for?
The SNMG 120408 T5125 insert (Tungaloy turning insert, SKU 6852988-Tungaloy) is optimised for cast iron applications and performs well in interrupted cutting where toughness is required.

Can this insert be used for internal turning as well as external turning?
Yes, the square ISO format and 90° geometry make the insert suitable for both external and internal turning operations when paired with the appropriate holder.

What makes the T5125 grade different from standard grades?
The T5125 grade is a tougher, CVD-coated carbide designed to resist chipping during interrupted cuts and to maintain cutting-edge reliability under less stable machining conditions.

How does the cylindrical hole affect clamping and repeatability?
The cylindrical hole allows precise seating and positive location in ISO-compatible clamping systems, improving repeatability and reducing the risk of misalignment during indexation.

Is the insert indexable and how many usable edges does it offer?
The insert is double-sided, providing two usable cutting edges per index and delivering an economical cost per edge.
