DCMT070204 T9215 DCMT indexable turning insert, 0.4 mm nose radius, 7° clearance (Tungaloy)

The DCMT070204 T9215 is an ISO-standard indexable turning insert designed for external and internal turning, optimised for medium-steel machining and continuous to lightly interrupted cuts.

• CVD-coated cemented carbide T9215
• 0.4 mm nose radius for precision
• 7° clearance angle for stable cutting
• Rhombic DCMT geometry, size 07
• Cylindrical hole with 40°–60° countersink

Boosted productivity for medium-steel turning

The combination of CVD coating and a cemented carbide substrate in this grade delivers enhanced wear resistance without sacrificing toughness. That makes the insert particularly suitable for the medium steel sector, where a balance between tool life and edge strength is required. The result is more consistent cycle times and less frequent index changes, improving throughput and process reliability in repetitive turning operations.

Geometry that stabilises the cut and improves surface finish

The 0.4 mm nose radius and 7° clearance create a cutting geometry that reduces chatter and supports a predictable chip flow. The rhombic form provides two usable cutting edges per index, enabling fast indexing while maintaining a compact insert footprint in the holder. Together these features contribute to a finer surface finish and reduced rework for turned components.

Compatibility and safe clamping for consistent results

Delivered as an ISO-standard turning insert, compatibility with the correct external holder depends on insert form, clearance angle, tolerance class, clamping method, size and thickness. The insert is supplied with a hole (cylindrical plus one-sided countersink 40°–60°), which ensures secure seating and repeatable positioning when mounted. Selecting the appropriate holder and torque for the clamping screw preserves cutting-edge geometry and reduces the risk of unexpected edge failure.

Practical benefits and process advice

The T9215 grade is tuned for continuous to lightly interrupted cuts, offering a balance of wear resistance and fracture toughness that supports higher metal removal rates in production turning. For stable results, pair the insert with a correctly matched DCMT external holder, select feed and speed in line with workpiece rigidity, and prefer steady coolant or lubrication to prolong edge life. This approach keeps cycles predictable and reduces unplanned downtime.
