DPMT 11T304 T9225 turning insert by Tungaloy — 55° rhombic, 0.4 mm radius

A DPMT11T304 T9225 insert engineered for medium-to-heavy turning operations, offering a CVD-coated carbide grade for greater toughness under variable engagement and interrupted cuts.

• CVD-coated carbide grade T9225
• For medium to heavy steel turning
• 55° rhombic form, 0.4 mm nose radius

Durable grade engineered for variable engagement

The CVD-coated T9225 is a carbide grade developed for robust, universal performance in turning applications where changing cut conditions or slight interruptions demand additional toughness. This composition combines wear resistance with edge stability, giving reliable tool life during medium-to-heavy steel machining. The coating improves heat resistance and adhesion, which contributes to more consistent cutting forces and reduced flank wear when the machining task alternates between finish and heavier passes.

ISO compatibility and straightforward system integration

Being an ISO-standard insert, compatibility is determined by form, clearance angle (11°), tolerance class, fastening and the plate’s thickness. The insert integrates into standard holders and boring bars when those parameters match; a complete system typically comprises an ISO insert, a compatible external holder or boring bar, an underlay/clamping set and replacement screws. This modular approach simplifies tooling management and helps maintain consistent setup repeatability across different machines and operators.

Geometry that balances surface finish and durability

The 55° rhombic shape with a 0.4 mm nose radius provides an excellent compromise between surface quality and cutting-edge strength. A smaller nose radius reduces cutting forces and improves dimensional control for finishing passes, while the rhombic angle supports stable engagement and positive chip flow. The one-sided chipbreaker and a central hole with a cylindrical body plus a single-side countersink (40°–60°) ensure secure clamping and effective chip control for both light and heavier cuts, reducing the risk of built-up edge under challenging conditions.

Application guidance and operational advantages

Designed for both external and internal turning, this insert performs well when paired with an appropriate chipbreaker and matched to workpiece material and rigidity. Selection of the correct grade and chip geometry is critical: T9225 excels in steel machining where intermittent cuts or varying engagement occur. The system setup—insert, suitable holder, clamping set and replacement screws—supports quick changeovers and predictable results, helping to increase process reliability and reduce downtime in production environments.

FAQ

Which materials is this insert best suited for?
The Tungaloy DPMT11T304 T9225 insert is optimised for medium-to-heavy steel machining and performs well under variable engagement and slightly interrupted cuts.

What does the T9225 grade provide?
T9225 denotes a CVD-coated carbide grade that offers a balance of wear resistance and toughness, improving edge stability for demanding turning operations.

How is holder compatibility ensured?
Compatibility depends on the insert form, 11° clearance angle, tolerance class, fastening, 11 mm size and 3.97 mm thickness; matching these parameters ensures correct integration with the chosen holder or boring bar.

What surface finish can be expected with a 0.4 mm nose radius?
A 0.4 mm nose radius supports good dimensional control and a fine surface when used for finishing passes while maintaining sufficient edge strength for mixed-duty cutting.

Is the insert supplied as part of a system?
The product is an ISO insert intended for use with a compatible external holder or boring bar and requires an underlay/clamping set and replacement screws for full system assembly.
