DPMT11T308 T9225 Turning Insert (rhombic, 55°) – Tungaloy

DPMT11T308 T9225 is a precision ISO turning insert designed for external and internal turning in steel, offering a robust universal grade for medium to heavy machining.

• CVD-coated carbide for durability
• Universal T9225 for medium to heavy steel
• Rhombic 55° geometry for versatile turning
• 0.8 mm corner radius for reliable edge strength

Consistent cutting performance for demanding steel operations

The combination of CVD-coated surface and carbide substrate in this grade provides a balanced wear resistance and toughness profile. This makes the insert especially suitable for medium to heavy steel machining where varying engagement conditions or light interruptions occur. The coating reduces flank wear, while the substrate maintains integrity under load, which translates into longer tool life and fewer insert changes — a direct productivity advantage for batch production or continuous turning tasks.

Simple integration into ISO tooling systems

Designed to ISO standards, the rhombic geometry with a 55° main cutting angle and a 11° clearance ensures compatibility with widely used holders. Key dimensions such as the 11 mm size, 3.97 mm thickness and central hole with cylindrical bore plus a single-sided countersink (40°–60°) facilitate secure clamping and repeatable positioning. Compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness, so selection of an appropriate holder and clamping set is essential for stable results.

Practical benefits and recommended use

The single-sided chipbreaker and 0.8 mm corner radius are tuned for stable chip formation and edge strength when turning steel components. For external and internal turning operations where interrupted cuts or variable depths of cut are expected, this universal grade offers a reliable balance between toughness and wear resistance. Select the chipbreaker and grade according to workpiece material, machining type and machine-tool rigidity to achieve the best surface finish and repeatable productivity.

FAQ

What materials is this insert suitable for? The insert is optimised for machining steel in medium to heavy cuts; the T9225 CVD-coated carbide grade provides a balance of toughness and wear resistance for such applications.

How does the T9225 grade behave with interrupted cuts? The T9225 grade was developed for robust, universal performance and offers increased toughness to withstand light interruptions and varying engagement conditions during turning.

Which holders are compatible with this ISO insert? Compatibility requires a holder matching the insert form, clearance angle (11°), tolerance class, clamping method and size (11 mm, thickness 3.97 mm); ISO-compatible external or boring holders designed for rhombic 55° inserts are suitable.

What is the purpose of the single-sided chipbreaker? The single-sided chipbreaker promotes controlled chip formation for turning operations, improving evacuation and reducing the risk of built-up edge on the cutting edge during steel machining.

Is the insert supplied with mounting screws or clamping sets? The insert is supplied as a single ISO turning insert; a suitable corresponding holder, support/lock set and replacement screws should be selected separately to ensure correct clamping and repeatable positioning.
