DPMT 11T308 T9225 — ISO turning insert, CVD-coated carbide (Tungaloy)

DPMT11T308 T9225 is an ISO-indexable turning insert engineered for external and internal turning in medium to heavy steel machining, offering a one-sided chipbreaker and a cylindrical hole with a single-sided countersink for secure clamping.

• CVD-coated carbide grade T9225
• 0.8 mm corner radius for robust edges
• One-sided chipbreaker for steel machining
• Cylindrical hole with countersink 40°–60°

Consistent productivity for medium to heavy turning

The T9225 cutting grade combines a CVD coating with a tough carbide substrate to deliver a durable balance between wear resistance and edge strength. This results in reliable tool life under variable engagement and slightly interrupted cuts, reducing unscheduled index changes and maintaining cycle times. The robust composition supports stable chip formation and helps to maintain cutting parameters for longer, which improves overall process efficiency and part repeatability.

Geometry that simplifies set-up and repeatability

The rhombic plate geometry with a nominal included angle of 55° and a clearance angle of 11° provides a versatile cutting orientation for a wide range of turning tasks. The 0.8 mm corner radius gives edge strength where intermittent cuts or higher feed rates are encountered, while the cylindrical hole with one-sided countersink (40°–60°) ensures positive and reproducible clamping in ISO-compatible toolholders. These mechanical features reduce set-up variability and support consistent insertion seating during index changes.

Practical design for efficient workshop use

With a plate thickness of 3.97 mm and standard ISO dimensions, the insert integrates smoothly into common turning systems. The one-sided chipbreaker is tuned for steel machining to promote controlled chip flow and minimise rework due to entangled swarf. The standardised form and tolerances make tool inventory management simpler, as replacement inserts and associated clamping kits are interchangeable across matching ISO holders, shortening downtime and streamlining tool logistics.

Choosing the right grade and application notes

The universal, robust character of this grade makes it suited to a broad spectrum of steel turning tasks where variable engagement or light interruptions occur. For consistent finishes and productivity, match the one-sided chipbreaker and T9225 grade with appropriate feeds and speeds for the workpiece material; higher toughness allows slightly more aggressive feeds without compromising edge security. For precision finishing or non-steel materials, alternative grades or different chipformers may be more advantageous.
