DCMT 11T304 T9215 — Turning indexable insert, 55° rhombic, CVD-coated carbide (Tungaloy)

A DCMT11T304 T9215 Tungaloy indexable insert designed for ISO-compliant turning, optimised for medium steel machining and productive continuous to slightly interrupted cuts

• Rhombic 55° geometry
• CVD-coated carbide T9215
• 0.4 mm corner radius
• Single-sided chipbreaker

Higher productivity through durable coating and grade

The insert combines a CVD-coated carbide body with the T9215 grade to deliver high wear resistance and enhanced breakage safety, which directly increases tool life and reduces machine downtime. For continuous or slightly interrupted turning operations, this wear-resistant composition supports longer cutting intervals and fewer index changes, improving overall process economy. The combination of coating and grade is particularly effective in medium steel machining, permitting higher cutting speeds where stability allows.

Precision fit and predictable cutting geometry

Built to the ISO 11T304 designation, the rhombic 55° shape and a relief angle of 7° ensure consistent engagement with appropriately matched holders. The insert’s 0.4 mm corner radius gives a defined cutting edge suitable for general finishing and semi-finishing passes, while the 3.97 mm thickness and 11 mm size provide mechanical stability in standard turning tool systems. Compatibility is determined by holder form, clearance angle, tolerance class, mounting and size, so choosing a matching outside holder or boring bar ensures repeatable results and secure clamping.

Application guidance and operation advantages

The single-sided chipbreaker promotes controlled chip formation in external and internal turning, improving surface finish and evacuation. This indexable insert performs best in medium steel workpieces and is set up for productive machining where continuous cutting prevails. Because the grade balances wear resistance with fracture toughness, it is a pragmatic choice for manufacturers seeking a reliable everyday insert that reduces scrap risk and supports stable batch production. For setups with slight interruptions, the insert maintains edge security while enabling competitive cutting parameters.

Practical notes on selection and use

When selecting an insert grade and chipbreaker, match the combination to material, cutting conditions and machine stability: the T9215 grade suits a broad range of steels, and the rhombic geometry offers versatility for both external and internal turning. The insert is supplied with a central hole featuring a cylindrical bore and a one-sided countersink (40°–60°), facilitating standard clamping systems. For newcomers, the CVD coating provides a wear-protective layer by chemical vapour deposition, which increases resistance to abrasive wear without sacrificing the substrate’s toughness.

FAQ

What materials is this insert best suited for?
The DCMT11T304 T9215 insert is optimised for medium steel machining; the T9215 CVD-coated carbide grade offers a balance of wear resistance and toughness suited to continuous turning operations.

How does the chipbreaker affect performance?
The single-sided chipbreaker on the insert promotes stable chip formation and evacuation, improving surface finish and reducing the risk of chip-related disturbances during turning.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, mounting method, size and thickness; use holders specified for ISO 11T304 rhombic inserts for secure clamping.

What are the key geometric specifications to note?
Important dimensions include the 55° rhombic geometry, 0.4 mm corner radius, 3.97 mm thickness and the 7° relief angle, which together determine the cutting behaviour and mechanical stability.

Is this insert suitable for interrupted cuts?
The insert is intended for continuous to slightly interrupted cuts; the T9215 grade provides fracture resistance for light interruptions but heavy interrupted cutting may require a different grade or geometry.
