DPMT 070202 T9225 ISO indexable turning insert for Turning — Tungaloy

The DPMT070202 T9225 is an ISO rhombic indexable insert intended for external and internal turning applications, offering robust performance in demanding steel machining.

• CVD-coated carbide for high toughness
• Rhombic 55° geometry for versatile turning
• 0.2 mm corner radius for accurate profiles
• One-sided chipbreaker for controlled chip flow

Increased throughput through reliable cutting performance

The combination of a CVD-coated carbide substrate and the T9225 grade delivers a reliable balance of wear resistance and toughness, specifically tuned for medium-to-heavy steel turning. This results in longer edge life under varying engagement conditions and when occasional interruption occurs in the cut. The 55° rhombic geometry enables stable cutting forces and flexible approach angles, which helps maintain higher feed and speed settings without compromising component tolerances or requiring frequent insert changes.

Compatibility and secure clamping for predictable operation

Compatibility with the toolholder is determined by holder form, relief angle, tolerance class, clamping method, size and thickness; the insert features a cylindrical hole with a single-sided countersink (40°–60°) for positive seating. The combination of hole design and the specified plate thickness ensures secure fixation in standard ISO external holders or boring bars. The one-sided chipbreaker supports consistent chip formation and evacuation, reducing the risk of entanglement and promoting predictable process stability during both external and internal turning tasks.

Why the coating and grade matter for part quality

A CVD-coated carbide insert like this provides a hard, wear-resistant outer layer bonded to a tough carbide substrate. Chemical vapour deposition (CVD) coatings increase resistance to abrasive wear and edge adhesion at elevated temperatures, while the underlying carbide maintains fracture toughness. The T9225 grade is a universal, robust option for workshop environments where cutting conditions change or where slightly interrupted cuts occur; it therefore supports consistent surface finish and dimensional accuracy across batches.

Practical benefits at the machine and on the shop floor

The small 0.2 mm corner radius is suitable for fine profile control and sharp internal contours while still offering sufficient edge strength for heavier passes when required. The rhombic shape and 55° included angle make the insert versatile for a range of turning operations, reducing the number of tool changes and supporting leaner tool inventories. Selecting the appropriate chipbreaker and matching the grade to the workpiece material will yield the best compromise between productivity and tool life, enabling more predictable cycle times and reduced downtime.

FAQ

Which materials is this insert suitable for machining?
The DPMT070202 T9225 indexable turning insert by Tungaloy is optimised for medium-to-heavy steel machining but may be selected for similar ferrous applications where toughness is required.

How does the T9225 grade affect performance?
The T9225 grade combines a CVD-coated carbide surface with a tough substrate to provide wear resistance and fracture toughness, enhancing durability under variable engagement and slightly interrupted cuts.

What does the hole and countersink provide during mounting?
The cylindrical hole with a single-sided countersink (40°–60°) in the DPMT070202 insert ensures secure seating and reliable clamping in compatible ISO toolholders, improving repeatability and reducing movement under heavy loads.

What advantages does the 0.2 mm corner radius offer?
A 0.2 mm corner radius delivers precise profile control and improved edge strength for finishing passes, supporting fine contours without sacrificing resistance to chipping during heavier cuts.

Is the insert suitable for both external and internal turning?
Yes, the rhombic 55° geometry and the design features of the DPMT070202 Tungaloy insert make it appropriate for both external and internal turning operations when matched with the correct holder and machining parameters.
