SNMG 120404 T9215 indexable turning insert by Tungaloy — CVD-coated carbide for medium steel, square 12 mm

SNMG 120404 T9215 is an ISO‑format indexable turning insert designed for general turning. Its geometry and tolerances ensure compatibility with standard external holders and boring bars while the T9215 grade provides a balance of wear resistance and fracture toughness for productive machining.

• ISO-standard SNMG insert, square 12 mm
• CVD-coated carbide grade T9215 for steel
• Double-sided chipbreaker for stable chips
• 0.4 mm corner radius, 4.76 mm thickness

High productivity through optimised wear resistance

The CVD‑coated carbide T9215 delivers a predictable wear pattern that supports uninterrupted production runs and higher machining speeds in medium steel applications. Thanks to its engineered coating and substrate combination, the grade offers both abrasion resistance and edge stability, which reduces insert changes and keeps cycle times consistent. This results in improved machine utilisation and lower per-part tooling cost, a clear advantage for batch production and continuous turning operations.

Reliable fit and ISO conformity for safe integration

As an ISO-standard SNMG120404 insert, compatibility with holders is determined by shape, relief angle, tolerance class and thickness; this ensures repeatable clamping and accurate seating in standard carriers. The square, 12 mm form and 4.76 mm thickness make the insert straightforward to match with common external holders or boring bars, simplifying tool inventory and setup. Clear adherence to ISO norms reduces the risk of misfit and supports quick indexation during runtime.

Consistent chip control and edge robustness

The double-sided chipbreaker and the 0.4 mm corner radius combine to deliver controlled chip formation and improved surface integrity on medium steel workpieces. The cylindrical hole and secure attachment reduce vibration at the cutting edge, which enhances edge life and surface quality under continuous to lightly interrupted cuts. These features make the insert especially suitable where stable chip evacuation and repeatable finish are required.

Efficient system workflow and application flexibility

The insert is intended as part of a tooling system comprising the indexable plate, matching external holder or boring bar, and retaining hardware; this modular approach supports rapid replacement and reduces machine downtime. Selection of the correct chipbreaker and grade for the workpiece and cutting conditions enables tailored performance—whether for finishing or productive roughing—so workshops can adapt the same geometry across multiple jobs while keeping stocking and handling minimal.

FAQ

What materials is this insert best suited for? The Tungaloy SNMG120404 T9215 insert is optimised for medium steel machining; the CVD-coated carbide grade T9215 balances wear resistance and fracture toughness for productive turning.

How is the SNMG120404 secured in the holder? The insert uses a central cylindrical hole and standard ISO geometry for secure clamping in compatible external holders or boring bars; correct seating depends on form, tolerance class and thickness.

Can the insert be indexed to present a fresh cutting edge? Yes, the SNMG120404 is double‑sided, allowing indexation to a fresh edge which extends usable life and reduces tooling costs in batch production.

Is this insert suitable for interrupted cuts? The T9215 grade provides good toughness for light to moderate interrupted cuts; heavier interruptions may require a lower‑risk geometry or cutting strategy.

What edge preparation does the 0.4 mm radius provide? A 0.4 mm corner radius helps to distribute cutting forces and improves surface finish on turning operations while maintaining edge strength for general‑purpose applications.
