SNMG 120412 T5115 ISO turning insert, CVD-coated — Tungaloy

The SNMG120412 T5115 is an ISO-standard, CVD-coated carbide indexable insert designed for external and internal turning, optimised for reliable machining of cast iron.

• ISO SNMG 120412 geometry
• CVD-coated carbide for cast iron
• Double-sided chipbreaker
• 1.2 mm corner radius
• Square plate, 90° cutting angle

Consistent edge life through CVD-coated carbide

The CVD-coated carbide grade T5115 provides a balanced combination of wear resistance and edge stability, which translates into fewer tool changes and steadier process output when machining cast iron. The coating reduces abrasive wear and helps maintain a cutting edge at elevated temperatures, resulting in consistently predictable surface finish and longer service periods between indexings. This performance advantage supports higher machine utilisation and reduces unplanned stoppages, making production planning more reliable.

Precise geometry for improved chip control and stability

The insert’s double-sided chipbreaker and 1.2 mm corner radius promote controlled chip formation and secure cutting behaviour in interrupted or stable cuts. The square form with a 90° lead angle offers robust support at the cutting edge, reducing chatter and deflection on less rigid setups. Improved chip control lowers the risk of built-up edge and workpiece rework, while the compact corner radius helps achieve a balance between edge strength and fine surface quality during finishing passes.

ISO compatibility that simplifies tool selection and setup

Designed to the ISO designation SNMG120412, the insert integrates easily into standard indexable tooling systems; compatibility with a holder depends on form, clearance angle, tolerance class, fastening, size and thickness. This ISO conformity streamlines procurement and replacement logistics and allows for quick changeovers between toolholders and machines. For customers aiming to harmonise tool inventories across machines, the standard geometry reduces the need for bespoke holders and shortens setup times.

Application guidance and handling advantages

Intended primarily for turning operations on cast iron, the insert’s universal grade and balanced geometry make it suitable for a range of roughing and finishing tasks. The cylindrical hole and standard thickness of 4.76 mm ensure secure clamping in compatible holders, while the double-sided design permits economical indexing. Selecting the appropriate chipbreaker and feed parameters according to workpiece stability will maximise the grade’s life and maintain dimensional accuracy in serial production.

FAQ

What machining tasks is this insert designed for?
The SNMG120412 T5115 insert is designed for external and internal turning, with a universal grade optimised for machining cast iron.

Which materials are best suited to this grade?
Grade T5115 is formulated for cast iron and provides a balance of wear resistance and edge stability suitable for a wide range of grey and ductile cast-iron applications.

What are the key dimensional specifications to check before fitting?
Check the plate size (12 mm), thickness (4.76 mm), corner radius (1.2 mm) and the ISO designation SNMG120412 to ensure correct holder fit and clamping.

How does the chipbreaker design affect machining?
The double-sided chipbreaker promotes stable chip formation and evacuation, enhancing process reliability and reducing the risk of built-up edge during longer machining cycles.

How is holder compatibility determined for this insert?
Holder compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters ensures secure clamping and correct cutting geometry.
