DCMT 11T304 T9215 Tungaloy indexable turning insert — rhombic 55°, CVD‑coated carbide

The DCMT 11T304 T9215 indexable insert for turning delivers a balance of wear resistance and fracture toughness, optimised for external and internal turning of medium steel.

• ISO‑standard 55° rhombic insert
• CVD‑coated T9215 grade for medium steel
• 0.4 mm corner radius for versatile turning
• Cylindrical hole with single countersink

Productive performance for medium‑steel turning

The CVD‑coated carbide formulation of the T9215 grade combines high wear resistance with robust fracture toughness, making this insert a strong choice for continuous and slightly interrupted cuts. With a 0.4 mm corner radius and a rhombic 55° geometry, the insert supports stable cutting forces and consistent tool life, which contributes to higher throughput and predictable process windows. These material and geometry choices are aimed at workshops and production lines that require reproducible results and minimal downtime between tool changes.

Geometry and chip control that stabilise machining

A clear advantage of this insert is its geometry: the 55° main cutting angle and single‑sided chipbreaker provide controlled chip formation while maintaining versatility across common turning tasks. The cylindrical hole with single countersink (40°–60°) ensures secure clamping and repeatable seating in compatible holders, reducing the risk of vibration and edge chipping. When combined with the CVD coating, this geometry helps to maintain cutting edge integrity and surface finish, especially during longer tool engagements and light interruptions in the cut.

Compatibility guidance and practical application

As an ISO‑standard indexable insert, compatibility with a holder depends on form, clearance angle, tolerance class, clamping method, size and thickness. The DCMT designation and the ISO code 11T304 indicate the insert form and size, while the plate thickness of 3.97 mm and size 11 must match the intended clamp seat. This insert is intended primarily for turning and is well suited to both external and internal operations on medium steel; selecting the appropriate holder and adapting cutting parameters to the T9215 grade will yield the best balance between productivity and tool life.

FAQ

Which machining tasks is this insert designed for?
The DCMT11T304 Tungaloy indexable insert is designed for external and internal turning operations, particularly suited to medium‑steel machining where continuous or slightly interrupted cuts are common.

Is the T9215 grade suitable for high‑productivity applications?
Yes, the T9215 grade used on the DCMT11T304 insert provides a combination of wear resistance and fracture toughness that supports high productivity while maintaining tool life under typical turning conditions.

What are the key geometry details to check when selecting a holder?
Check for a rhombic 55° seat, matching plate size (11) and thickness (3.97 mm), the 0.4 mm corner radius, and a mounting arrangement that accepts a cylindrical hole with a single countersink; these ensure correct seating and clamping of the insert.

Which materials can be machined with this insert?
The insert is optimised for medium steel; its carbide substrate and CVD coating are chosen to handle typical steels encountered in production turning.

How is clamping ensured for repeatable performance?
Repeatable performance with the DCMT11T304 insert is achieved by matching the insert form and dimensions to an ISO‑compatible holder and using the specified clamping hardware; the cylindrical hole and single countersink support secure, repeatable seating.
