DCMT 11T304 T9225 indexable insert for turning — Tungaloy

A DCMT11T304 indexable turning insert designed for medium to heavy steel machining, offering a CVD-coated carbide grade for reliable edge life and versatile chip control

• CVD-coated carbide T9225 for robustness
• ISO-compatible rhombic geometry, 55° approach angle
• 0.4 mm corner radius for accurate profiles
• Cylindrical hole with one-sided countersink 40°–60°

Stable cutting performance under varied conditions

The CVD-coated carbide composition of this insert offers a balance of hardness and toughness that suits interrupted cuts and fluctuating engagement conditions. The T9225 grade is configured as a robust universal option for steel turning, enabling consistent cutting forces and prolonged edge life compared with uncoated grades. For production environments where reproducible results and reduced tool changes matter, this combination leads to lower process variability and improved throughput.

Geometry that supports precision and surface quality

With a rhombic form and an approach angle of 55°, the insert produces predictable chip flow and load distribution across the cutting edge. The specified 7° clearance and a 0.4 mm corner radius contribute to accurate dimensional control and help achieve the desired surface finish on turned components. The compact nose radius is especially useful when machining detail features or maintaining tight tolerances on shafts and bores, while the plate thickness of 3.97 mm ensures mechanical stability during heavier cuts.

System compatibility and straightforward mounting

The insert conforms to ISO indexable insert standards; compatibility with a toolholder is determined by form, clearance, tolerance class, fastening method, size and thickness. The component is supplied with a cylindrical hole and one-sided countersink (40°–60°), making it suitable for common screw-clamped holders and certain bore-type fixing systems. When assembling the cutting system, pair the insert with an appropriate ISO external holder or boring bar and the correct clamp/washer set to secure repeatable positional accuracy.

Chip control and application-specific advantages

Equipped with a one-sided chipbreaker, the insert channels chips efficiently during longitudinal and facing operations, reducing the risk of entanglement and supporting safer automated handling. The grade selection—T9225—is optimised for mid-to-heavy steel machining; it combines stable chip formation with good wear resistance, which is beneficial for batch production and mixed-run shops. For best results, match feed and speed to the workpiece material and machine rigidity to exploit the grade’s balance of toughness and wear resistance.

FAQ

What materials is this insert suited for?
The DCMT11T304 T9225 indexable insert (Tungaloy, SKU TUN6781041) is primarily designed for medium to heavy steel machining and performs well under interrupted cuts and varying engagement.

How does the CVD coating benefit machining?
A CVD-coated surface on this insert improves wear resistance and thermal stability, so the Tungaloy DCMT11T304 T9225 maintains cutting performance for longer on demanding turning operations.

Which toolholders are compatible with this insert?
Compatibility is based on ISO form, clearance angle, tolerance class, fastening and size; the DCMT11T304 fits standard ISO rhombic holders and screw-clamp systems that accept inserts with a cylindrical hole and one-sided countersink.

Is the corner radius suitable for finishing work?
The 0.4 mm corner radius provides a balance between profile accuracy and edge strength, making the insert suitable for fine profiles and moderate finishing passes on shafts and stepped components.

What chip control can be expected with the one-sided chipbreaker?
The integrated chipbreaker offers controlled, short chips in typical turning feeds, improving machine safety and chip evacuation during both longitudinal turning and facing operations.
