SNMG120416 T5115 SNMG indexable insert for turning — Tungaloy

SNMG120416 T5115 is a square ISO indexable insert designed for external and internal turning, offering a universal CVD-coated carbide grade for reliable performance on cast iron.

• CVD-coated carbide for wear resistance
• Universal grade for cast iron machining
• Square 90° shape for versatile turning
• Double-sided chipbreaker for controlled chips

Durable grade for efficient cast-iron turning

The supplied insert is a CVD-coated carbide grade (T5115) developed as a universal solution for machining cast iron. The coating provides improved wear resistance while the carbide substrate maintains a stable cutting edge, which together reduce tool change frequency and support consistent cycle times. This combination benefits production lines where predictable tool life and repeatable results are required. The universal nature of the grade balances toughness and hardness, making it suitable for varied roughing and finishing tasks without excessive compromise.

Precise geometry and fit for ISO tooling systems

The geometry follows ISO conventions for square turning inserts and the form, clearance, tolerance class, fastening style, size and thickness determine holder compatibility. The insert features a 90° lead angle and a 0° clearance angle, with a plate thickness of 4.76 mm and a nominal size of 12 mm, so matching the correct external holder or boring bar is essential to achieve intended chip flow and cutting forces. Cylindrical hole mounting ensures reliable clamping; correct seating and torque prevent vibration and extend service intervals. Compatibility notes: check holder pocket shape and screw type against the ISO designation.

Optimised chip control and edge stability

A double-sided chipbreaker is integrated to manage chips across a range of depths of cut and feed rates. The chipformer design combined with the T5115 grade assists in producing shorter, manageable chips when turning cast iron, reducing secondary operations and improving surface quality. The insert’s 1.6 mm nose radius provides a compromise between strength and finish: it increases edge robustness for interrupted cuts while allowing good surface results in finishing passes when the setup is rigid and cutting parameters are optimised.

Process guidance for consistent performance

For best results, select a holder and machining parameters that match the insert’s geometry and the workpiece material: stable clamping and adequate rigidity maximise edge life and dimensional accuracy. The indexable design permits rotation to fresh cutting edges, reducing tooling costs per component. Where high material removal rates are required, combine the insert with a suitably rigid toolholder and adjust feed to maintain the chipbreaker’s effectiveness. For fine finishes, reduce feed and use the nose radius to improve surface integrity while preserving tool life.

FAQ

What materials is this insert suitable for?
The Tungaloy SNMG120416 T5115 insert is a universal grade specifically intended for machining cast iron and delivers a balanced mix of wear resistance and edge stability for turning operations.

How is the insert mounted and how to ensure compatibility?
Compatibility depends on holder pocket form, clearance, tolerance, fastening and thickness; the SNMG120416 uses a cylindrical-hole clamping system—verify the holder matches the ISO form and screw type.

What advantages does the T5115 CVD coating offer?
The T5115 CVD-coated carbide provides improved wear resistance and maintains a stable cutting edge under typical cast-iron turning conditions, extending tool life and supporting consistent part quality.

Can this insert be used for both roughing and finishing?
Yes, the universal nature of the grade and the 1.6 mm nose radius allow adaptable use across roughing and finishing tasks, provided the machine setup offers sufficient rigidity and the cutting parameters are tuned.

How does the chipbreaker affect machining?
The double-sided chipbreaker promotes controlled chip formation across a range of feeds and depths, aiding safe chip evacuation and reducing interruptions in automated production.
