DPMT11T302 11T302 T9225 — ISO turning insert (Turning) by Tungaloy

DPMT11T302 11T302 T9225 is a rhombic ISO turning insert designed for external and internal turning in industrial machining environments

• CVD-coated carbide grade T9225
• Robust universal grade for steel
• Rhombic 11-size, 0.2 mm corner radius
• Cylindrical hole with 40°–60° countersink

Reliable productivity for medium to heavy steel turning

The combination of a CVD-coated carbide substrate and the robust universal grade T9225 provides a dependable compromise between wear resistance and toughness. This makes the insert particularly suitable for medium to heavy steel machining where engagement conditions can vary or minor interruptions occur. The coating increases resistance to flank wear and abrasive attack, while the tougher substrate reduces chipping risk during changing cutting forces. As a result, the tooling system maintains cutting performance for longer, lowering the frequency of insert changes and increasing net machining time. The design supports stable, repeatable cutting, which is a practical advantage in production-focused workshops.

Seamless integration into ISO tooling systems

Compatibility with clamping systems is determined by the insert’s geometry, clearance angle, tolerance class, mounting style, size and thickness. The rhombic form and ISO designation simplify selection of matching external holders or boring bars, while the with-hole and single-side countersink enable secure mounting with standard screws and shims. Using appropriately matched components—holder, shim set and replacement screws—ensures correct seat fit, repeatable positioning and consistent cutting angles. This reduces setup time and minimises variation between tool changes, supporting higher first-pass yields and more efficient tool management.

Stability in variable engagement and interrupted cuts

The single-sided chipbreaker and the grade’s emphasis on toughness support controlled chip formation under fluctuating engagement. The 0.2 mm corner radius provides a balance between edge strength and surface finish, permitting higher feed rates without undue risk of edge failure. For operations with slight interruptions or periodic changes in cut depth, the insert’s composition and geometry maintain a stable cutting edge, which reduces scrap risk and secures consistent part quality. This predictable behaviour contributes directly to operational efficiency and process reliability.

Practical handling, mounting and lifecycle benefits

Handling is straightforward: the insert’s rhombic geometry and clear ISO sizing facilitate quick identification and correct seating. The 11° clearance angle and the 55° angle geometry combine to offer effective cutting engagement and predictable force transmission into the holder. Correctly matched screw and clamp sets keep the insert secure, enabling repeatable re-indexing and straightforward replacements. The net effect is lower downtime, fewer emergency interventions and a more economical tool cycle for batch and continuous production runs.

FAQ

What materials is this insert suitable for?
The DPMT11T302 in grade T9225 is intended primarily for medium to heavy steel machining; the composition and coating also allow handling of mixed engagement conditions with maintained edge stability.

How does one ensure compatibility with a holder?
Compatibility depends on insert form, clearance angle, tolerance class, mounting method, size and thickness; verify that the holder accepts the DPMT 11T302 geometry and uses the appropriate screw and shim arrangement.

Is the insert suitable for interrupted cuts?
Yes — the T9225 grade is a robust universal type that tolerates slight interruptions and variable engagement thanks to increased toughness and stable chip control.

What mounting features does the insert have?
The insert is supplied with a cylindrical hole and a single-side countersink (40°–60°) for screw mounting; a single-sided chipbreaker supports reliable chip formation during turning operations.
