SPMT 120404 T9215 indexable turning insert by Tungaloy — CVD-coated carbide for medium steel machining

SPMT120404 T9215 is an ISO-form square indexable insert designed for general external and internal turning where productivity and tool life are priorities.

• CVD-coated carbide grade T9215
• ISO SPMT 120404 square insert, 90° form
• 0.4 mm corner radius for precise finishing
• Cylindrical hole with 40°–60° countersink

Productive machining with robust CVD-coated carbide

The CVD-coated carbide of the T9215 grade combines enhanced wear resistance with the fracture toughness required for continuous to slightly interrupted cuts, making it a reliable choice for medium steel operations. This material pairing permits higher metal-removal rates with predictable tool life, supporting longer production runs and reduced tool-change frequency. The result is improved process efficiency and more consistent part quality when compared with uncoated or lower-grade alternatives.

Geometry and clamping that support repeatable precision

A square ISO form SPMT 120404 provides a 90° cutting edge suitable for a wide range of turning tasks; the 0.4 mm corner radius aids in achieving stable finishes without excessive cutting forces. The insert thickness of 4.76 mm and the 11° clearance ensure mechanical stiffness in standard holders, while the cylindrical hole with a one-sided countersink (40°–60°) secures accurate clamping. Compatibility with a toolholder is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so matching insert and holder specifications delivers consistent repeatability and reduced vibration.

Chip control, system setup and application advice

The single-sided chipbreaker is optimised for controlled chip formation in the target material range, improving surface quality and evacuation in steady cutting conditions. The insert forms part of a system comprising the indexable plate, an appropriate external holder or boring bar, a shim/clamp set and the correct fixing screws. For selection of the optimal chipbreaker and machining parameters, material-specific cutting data should be consulted; Metav Werkzeuge’s technical advisors can provide recommended feeds and speeds for typical turning cycles to help maximise productivity and component quality.

FAQ

What materials is this insert best suited for?
The SPMT120404 T9215 indexable insert by Tungaloy is optimised for medium steel machining and performs well in continuous to slightly interrupted cutting conditions.

How does the T9215 grade affect tool life and performance?
T9215’s CVD coating and carbide substrate increase wear resistance while maintaining fracture toughness, allowing higher productivity and more consistent tool life in turning operations.

What does the hole style mean for clamping?
The cylindrical hole with a one-sided countersink (40°–60°) on this insert ensures secure, repeatable clamping when paired with the correct holder and fastening hardware.

Is the SPMT120404 compatible with standard ISO toolholders?
Compatibility depends on matching the insert form, clearance angle, tolerance class, fastening method, size and thickness to the holder; the SPMT120404 form is a standard ISO geometry used in many external holders and boring bars.

Which SKU should be quoted when ordering?
Reference the manufacturer SKU TUN6774067 or the article number 6774067 when ordering to ensure the correct SPMT120404 T9215 insert is supplied.
