SCMT 120404 T9215 indexable insert for turning — Tungaloy

The SCMT120404 T9215 is a square ISO indexable insert designed for external and internal turning in medium steels, offering a balanced mix of wear resistance and fracture strength for continuous to lightly interrupted cuts.

• CVD-coated carbide T9215 for high wear resistance
• Optimised for medium steel machining
• ISO SCMT120404 square insert, 12 mm size
• 7° clearance angle and 0.4 mm corner radius

Productive chip control and stable cutting for turning

The insert delivers consistent chip formation thanks to its one-sided chipbreaker and the CVD coating. For machining medium steels, the T9215 grade combines enhanced wear resistance with fracture toughness, enabling longer tool life and fewer index changes. The chipbreaker geometry reduces built-up edge and supports steady material removal, which directly improves cycle times and lowers per-part costs.

Secure clamping and ISO compatibility reduce setup risks

Designed to the ISO SCMT120404 form, this square insert ensures predictable seating when matched to the correct holder. The cylindrical hole with single-sided countersink (40°–60°) promotes reliable screw engagement and repeatable positioning, while the standardised dimensions simplify tool inventory management. These factors reduce setup variability and support consistent surface finish across batches.

Material and coating explained for practical choice

Manufactured from solid carbide and CVD-coated, the cutting geometry is tailored for continuous and light interrupted cuts in a wide range of steel grades. The 0.4 mm corner radius offers a compromise between edge strength and surface finish, while the 4.76 mm plate thickness provides rigidity under typical turning forces. In practice, this means fewer insert chippings and improved process stability on production runs.

Integration into production workflows

The insert is intended for use with a matched external holder, clamp set and replacement screws as part of an ISO-compliant system. When paired with a suitable holder and correct cutting parameters, the insert supports stable tool life and repeatable results, helping to maintain throughput and minimise unplanned downtime. Selecting the right chipbreaker and grade for the workpiece material is critical to exploit the full benefit of the tool.

FAQ

What workpiece materials are best suited for this insert?
The SCMT120404 T9215 Tungaloy indexable insert (SKU 6774000-Tungaloy) is optimised for medium steels, combining wear resistance and toughness for productive turning in continuous to lightly interrupted cuts.

Can this insert be used for internal turning as well as external turning?
Yes — the ISO SCMT120404 form and chipbreaker design allow the insert to be used for both external and internal turning, provided a compatible holder and correct cutting parameters are used.

What advantages does the T9215 grade provide?
The T9215 grade features a CVD coating that improves wear resistance while maintaining fracture strength, resulting in longer tool life and reliable performance in medium steel machining.

How does the 0.4 mm corner radius affect results?
A 0.4 mm corner radius offers a balance between edge strength and surface finish: it increases resistance to chipping while delivering acceptable surface quality for general turning tasks.

Is the insert compatible with standard ISO clamping systems?
Yes — the insert follows the ISO SCMT120404 geometry and is compatible with holders and clamping systems designed for that standard form factor.
