DCGT11T304 GT9530 Tungaloy turning insert — coated cermet, 0.4 mm radius, rhombic 55°

The DCGT11T304 GT9530 is an ISO-format rhombic turning insert intended for finishing and light general turning of steel under stable machining conditions.

• Coated cermet grade GT9530 for long tool life
• Rhombic 55° geometry for versatile turning
• 0.4 mm corner radius for fine surface finishes
• Cylindrical hole with 40°–60° countersink

Consistent finishing performance and extended life

The combination of the GT9530 coated cermet and the insert geometry delivers a measurable improvement in surface quality during finishing operations. The wear-resistant grade is developed for schlicht- to light universal turning, which means the tool retains its cutting edge longer under steady conditions; this reduces changeover frequency and supports a predictable production rhythm. The fine 0.4 mm corner radius balances cutting stability with minimal cutting forces, producing a smoother workpiece face while keeping vibration low. Explanation: cermet coatings improve wear resistance and heat tolerance compared with uncoated grades, which helps to maintain consistent surface integrity across batches.

Stable geometry for predictable chip control and tool life

The rhombic 55° plate form, combined with a single-sided chipbreaker, provides controlled chip flow and stable engagement in both external and internal turning. The insert’s 7° clearance and standard ISO shape ensure repeatable contact conditions when paired with compatible holders; this geometric stability translates into predictable tool life and process reliability. In practical terms, stable geometry reduces the need for constant parameter adjustment and supports consistent part tolerances, which is particularly valuable in medium- to high-volume production runs where reproducibility is critical.

Easy integration into ISO tooling systems

Designed as part of the ISO turning insert family, the plate fits conventional external holders or boring bars provided the form, clearance angle, tolerance grade, attachment method, size and thickness match. The cylindrical hole with a one-sided countersink (40°–60°) facilitates secure clamping and straightforward replacement, while the 3.97 mm plate thickness and nominal size 11 match common toolholder specifications. This compatibility reduces setup time and simplifies inventory management, enabling a smoother workflow on the shop floor.

Selecting the right grade and chipbreaker for the application

The coated cermet GT9530 is optimised for steel machining when a good surface finish and extended wear resistance are priorities under stable conditions. For more aggressive roughing or unstable setups, alternative grades or chipbreakers may be preferable. The single-sided chipbreaker on this plate is effective for finishing cuts and light turning; choosing this insert supports a process that favours consistent part quality and lower finishing effort. For users less familiar with cermet behaviour, a short trial under controlled parameters is recommended to establish optimal speeds and feeds.

FAQ

What materials is this insert suited for?
The DCGT11T304 GT9530 insert is intended primarily for steel machining where finishing quality and longer tool life under stable conditions are required.

Which holder types are compatible with the insert?
Compatibility depends on holder form, clearance angle, tolerance class, attachment method, size and thickness; the plate is designed for standard ISO turning holders and boring bars compatible with a rhombic insert with a 55° included angle.

How does the GT9530 grade affect machining?
GT9530 is a coated cermet grade optimised for wear resistance and surface finish in finishing and light turning applications, helping to extend edge life and maintain consistent part quality.

Is the insert supplied with a chipbreaker?
Yes, the plate is equipped with a single-sided chipbreaker designed for controlled chip evacuation during finishing and light turning operations.

What are the key dimensions to check before ordering?
Confirm the inscribed size (11), plate thickness (3.97 mm), corner radius (0.4 mm), included angle (55°) and the presence of a cylindrical hole with countersink to ensure proper fit in the selected holder.
