SNMG120408 T9215 turning insert by Tungaloy — CVD-coated carbide, 0.8 mm radius

The SNMG120408 T9215 is an ISO-standard turning insert designed for external and internal turning, offering a robust CVD-coated carbide grade for productive medium-steel machining.

• CVD-coated carbide T9215 for wear resistance
• Optimised for medium steel machining
• Double-sided chipbreaker for stable chips
• 0.8 mm corner radius, square 90° geometry

Durable cutting performance for medium steels

The CVD coating on this carbide grade combines high wear resistance with reliable fracture toughness, making it suitable for continuous to light interrupted cutting. That balance supports longer tool life and fewer indexings, which translates into better machine utilisation and lower process interruptions. For workshops requiring steady throughput, the combination of coating and substrate reduces unscheduled tool changes and helps maintain surface quality during systematic turning cycles.

Precision geometry and ISO compatibility for predictable results

Built to ISO standards, the insert’s 90° square geometry and 0.8 mm nose radius provide defined cutting engagement and consistent wall forms in turning operations. The plate thickness of 4.76 mm and the square 12 mm size are matched to standard holders; compatibility depends on form, clearance angle, tolerance class, fastening and thickness. A 0° clearance angle and the cylindrical centre hole ensure repeatable seating and secure clamping in compatible toolholders, simplifying changeovers and supporting accurate part tolerances.

Stable chip control and efficient machining process

The double-sided chipbreaker is engineered for controlled chip formation in medium steels, aiding evacuaton and reducing cutting forces in many turning scenarios. The insert’s design supports a cost-efficient indexable system: insert, suitable outer holder or boring bar, shim and clamp set with replacement screws. This modular approach enables quick restoration of cutting edges and predictable tool life, improving overall process reliability. If uncertain about matching grade or chipbreaker to a specific component, technical consultation is available to ensure the right setup.

FAQ

What materials is this insert best suited for?
This insert, the Tungaloy SNMG120408 T9215, is optimised for medium steels and delivers a balance of wear resistance and fracture security for productive turning.

Is the insert reversible or single-sided?
The SNMG120408 insert features a double-sided chipbreaker and can be indexed to reuse the second cutting face, improving cost efficiency per insert.

How does the 0.8 mm radius affect finished parts?
A 0.8 mm nose radius helps achieve defined corner forms and stable tool engagement; it supports good surface finish while maintaining edge strength in general turning tasks.

Does the insert fit standard ISO holders?
The SNMG120408 conforms to ISO dimensions; compatibility with a holder is determined by geometry, tolerance class, fastening method, size and thickness—select a matching holder accordingly.

What advantages does the T9215 grade provide?
The T9215 CVD-coated carbide offers enhanced wear resistance together with breakage resistance, making it a solid choice for sustained productivity in medium-steel turning.
