DCMT 11T304 GT9530 turning insert — Tungaloy, coated cermet, 55°

DCMT 11T304 GT9530 is an ISO rhombic turning insert designed for finishing to light universal turning of steel where a fine surface and extended tool life are required

• Coated cermet GT9530 for improved life
• 55° rhombic form DCMT for versatile turning
• 0.4 mm corner radius for fine finishes
• Cylindrical hole with 40°–60° countersink

Achieve consistent finishes with a wear-resistant cermet grade

The GT9530 grade is a coated cermet tuned for finish to light universal turning of steel, providing a balance between surface quality and tool life when machining under stable conditions. Its composition promotes stable chip formation, which reduces vibration and helps maintain consistent cutting conditions over longer tool intervals. For production environments prioritising surface integrity on hardened process chains, this grade offers measurable improvements in repeatability and reduced rework.

Geometry engineered for precision and secure mounting

The rhombic DCMT geometry with an included angle of 55° and a 0.4 mm corner radius delivers controlled cutting engagement and excellent access to shoulder and profile features. The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) to match common ISO clamping systems; the plate thickness of 3.97 mm and a clearance angle of 7° ensure stable seating and predictable chip flow. The result is precise tool positioning, straightforward indexability, and compatibility with standard external holders and boring bars for seamless integration into existing tool assemblies.

Improve productivity through reliable chip control and system compatibility

The single-sided chipbreaker design simplifies selection for finishing tasks, supporting consistent chips and reduced interruption during turning cycles. When combined with an appropriate carbide-tipped holder and standard clamping kit, the insert contributes to reduced changeover time and fewer stoppages. The cemented carbide substrate provides the necessary edge support for the coated cermet layer, enabling longer tool life during steady-state operations and lowering total process cost per component in batch production.

Application guidance for workshops and production lines

Intended primarily for external and internal turning of steel, the insert suits job shops and industrial production where surface finish and component consistency are critical. Select this grade and the one-sided chipbreaker for operations with stable set-up rigidity and controlled feeds to exploit the coating’s strengths. For varied materials or heavy interrupted cuts, consider alternative geometries or grades matched to the specific alloy and cutting conditions; technical consultation is available for process matching and holder recommendations.
