SNMG120402 T9215 — SNMG 120402 Turning Insert (CVD-coated carbide, square, 0.2 mm) by Tungaloy

A SNMG120402 T9215 indexable turning insert developed for medium steel machining, offering robust wear resistance and reliable performance in continuous to lightly interrupted cuts.

• CVD-coated cemented carbide grade T9215
• ISO SNMG 120402 square form
• 0.2 mm nose radius for fine finishing
• Double-sided chipbreaker with cylindrical hole

High productivity for medium steel turning

The insert delivers predictable machining results thanks to the T9215 grade, a CVD-coated cemented carbide that balances wear resistance with fracture toughness. This combination enables longer tool life under sustained cutting conditions and supports higher cutting speeds without compromising component quality. The design focuses on efficiency: less frequent index changes and steady surface finish help reduce cycle times and improve overall throughput in serial production.

Secure clamping and wide holder compatibility

Designed to the ISO SNMG 120402 standard, the square indexable insert fits common external and internal turning holders when the form, clearance angle, tolerance class, attachment method, size and thickness match. The insert’s cylindrical hole and standardised geometry make integration into ISO holders straightforward, minimising set-up time and simplifying inventory management for workshops that run mixed tool systems.

Coating and substrate explained for reliable wear control

The grade combines a wear-resistant CVD coating with a tough cemented carbide substrate. The coating reduces adhesive and abrasive wear on the cutting edge, while the substrate absorbs cutting forces and resists chipping. For users less familiar with coating technology: CVD (chemical vapour deposition) forms a uniform layer that improves edge stability and keeps flank wear low, especially during long uninterrupted cuts.

Application guidance and chip control

The insert’s double-sided chipbreaker is optimised for medium steel and works well in continuous to light interrupted cuts; it promotes predictable chip formation and evacuation to protect the workpiece and toolholder. With a 0.2 mm nose radius, the geometry favours fine finishing passes and tight dimensional control. For heavier interrupted cuts, a different geometry or a larger radius may be preferable to increase edge strength.

FAQ

What materials is this insert suitable for?
The Tungaloy SNMG120402 T9215 insert is primarily intended for medium steel machining; the T9215 grade provides a balance of wear resistance and toughness suited to these materials.

How does the T9215 grade differ from general-purpose grades?
T9215 is a CVD-coated cemented carbide grade that emphasises wear resistance while retaining edge security, making it especially productive for continuous and lightly interrupted turning of medium steel.

Which holders are compatible with SNMG120402 inserts?
Compatibility depends on holder form, clearance angle, tolerance class, attachment type, size and thickness; holders designed for ISO SNMG120402 inserts with matching specifications will be compatible.

Can the insert be used for internal turning as well as external turning?
Yes, the ISO SNMG120402 geometry and cylindrical hole allow the insert to be used in both external and internal turning applications when installed in appropriate holders.

What does the 0.2 mm radius imply for surface finish?
A 0.2 mm nose radius favours finer surface finish and accurate dimensional control; it is suited to finishing passes and applications where tight tolerances are required.
