DPMT 11T308 T9225 — Tungaloy ISO turning indexable insert for external and internal turning

The DPMT11T308 T9225 is an ISO-format rhombic indexable insert engineered for moderate to heavy turning, offering a 55° geometry and a robust, universal grade for interrupted and variable cutting conditions.

• CVD-coated carbide T9225 for toughness
• ISO-format rhombic insert, 55° geometry
• Ideal for moderate to heavy steel turning
• Cylindrical hole with single-sided countersink

Increased process stability for demanding steel turning

The combination of a CVD-coated surface on a carbide substrate and the T9225 grade provides a reliable balance between wear resistance and toughness. This indexable insert is intended for medium to heavy machining where variable engagement or light interruptions call for enhanced fracture resistance. The coating reduces flank and crater wear, which extends effective tool life and helps maintain dimensional accuracy over longer production runs. For manufacturing environments aiming to reduce tool-change frequency and scrap rates, this insert supports a more efficient and predictable turning process.

Fast, repeatable clamping and straightforward compatibility

Designed to the ISO family of turning plates, the insert suits holders that match its rhombic shape, thickness and fixing geometry. The plate features a cylindrical hole with a one-sided countersink (40°–60°), ensuring secure, repeatable seating and consistent workpiece concentricity when mounted in a compatible holder. Compatibility is determined by holder form, clearance angle, tolerance class, method of fixing, size and thickness; confirming these parameters ensures quick set-up and reduced downtime during cutter changes. The standardised form factor simplifies inventory management when multiple tools share the same holder platform.

Practical selection advice for reliable machining results

Selection of the right chipbreaker and grade should reflect workpiece material, cut stability and desired surface finish. The single-sided chipbreaker supplied with this insert suits many turning tasks in steel where controlled chip formation is required. Where slightly interrupted cuts or tougher alloys are present, the T9225 grade offers additional toughness compared with more wear-focused grades, reducing the risk of chipping. For finishing operations requiring finer surface quality, consider optimising feed and speed while keeping the insert’s geometry and radius appropriate for the target profile.

FAQ

What operations is this insert suited for? The DPMT11T308 T9225 Tungaloy indexable insert (SKU 6951253-Tungaloy) is designed for external and internal turning, primarily in medium to heavy steel machining where occasional interruptions occur.

Will the insert fit standard ISO turning holders? Yes, the plate follows ISO dimensions; final compatibility requires matching the holder’s form, clearance angle, tolerance class, fixing method, size and thickness to the insert’s specifications.

What advantages does the T9225 grade provide? T9225 is a robust universal grade with CVD-coated carbide that emphasises toughness for variable engagement and light interruptions while still providing solid wear resistance for productive turning.

How does the hole and countersink design affect clamping? The cylindrical hole combined with a one-sided countersink (40°–60°) guarantees secure clamping, consistent seating and repeatable positioning, which aids in maintaining concentricity and reducing setup variation.

Which chipbreaker should be chosen for best results? Select the chipbreaker according to workpiece material, feed and stability; the single-sided chipbreaker on this insert supports controlled chip formation in many steel turning scenarios while balancing surface finish and evacuation.
