DCMT 11T308 T9225 – ISO turning insert for medium to heavy steel by Tungaloy

DCMT11T308 T9225 indexable turning insert engineered for robust performance in steel turning, offering a CVD-coated carbide grade and ISO-compatible geometry for reliable machining

• CVD-coated carbide for high wear resistance
• Robust universal grade for medium-heavy steel
• 55° rhombic geometry for versatile turning
• 0.8 mm corner radius and 7° relief angle

Reliable cutting performance for mixed turning operations

The DCMT11T308 T9225 insert combines a CVD-coated carbide substrate with a robust universal grade designed for medium to heavy steel machining, delivering extended tool life under variable engagement conditions. The single-sided chipbreaker and Tungaloy's T9225 chemistry promote stable chip formation, which reduces tool interruptions and supports predictable process behaviour in semi-continuous and slightly interrupted cuts. This results in fewer tool changes and lower production downtime, making the insert a practical choice where both performance and economy matter. Compatibility with ISO indexable tool systems ensures repeatable positioning and simplifies stock control of cutting edges.

Simple integration with ISO toolholders and secure clamping

Thanks to its 55° rhombic geometry and standard ISO designation, the insert fits a wide range of external holders and boring bars when the holder form, clearance angle, tolerance class, clamping method, size and thickness match. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to secure positive clamping and repeatable seating; the 3.97 mm thickness, 7° relief angle and 0.8 mm corner radius help balance edge strength and surface finish. These dimensional choices aid stable cutting in less rigid set-ups and make the component straightforward to integrate into existing turning tool systems without extensive requalification.

Increased productivity and dependable process security

Adopting this Tungaloy grade supports higher productivity through longer tool life and consistent cutting results on a range of steels. The combination of the CVD coating and the universal T9225 substrate offers improved resistance to flank wear and edge deterioration under fluctuating cutting conditions, reducing scrap risk and rework. For operations that require flexibility between finishing and medium-depth turning, the insert's geometry and chip control characteristics allow efficient chip evacuation and a stable cutting zone, which helps to maintain cycle times and surface quality. Choosing this insert contributes to a cost-effective machining strategy by lowering the frequency of index changes and supporting predictable component tolerances.

FAQ

Is this insert suitable for external and internal turning?
The DCMT11T308 T9225 indexable turning insert is suitable for both external and internal turning applications when used with the corresponding ISO holders and appropriate tool geometry.

Which materials are recommended for the T9225 grade?
Tungaloy's T9225 grade is optimised for medium to heavy steel machining and performs well under slightly interrupted cuts and varying engagement conditions.

How does the 0.8 mm corner radius affect the finish and edge life?
A 0.8 mm corner radius provides a balance between edge strength and surface finish; the DCMT11T308 insert benefits from improved edge durability while maintaining acceptable surface quality for general turning tasks.

Can the insert handle interrupted cuts?
Yes, the combination of the T9225 substrate and the insert geometry offers sufficient toughness for slightly interrupted cuts, supporting stable cutting and reduced edge chipping risk.

What must be considered when mounting this insert in a holder?
Ensure the holder matches the ISO form, clearance angle, tolerance class, clamping method, size and thickness; the cylindrical hole with countersink on the insert secures repeatable positioning and stable clamping.
