DCMT 11T304 GT9530 — Rhombic ISO turning insert, coated cermet, Tungaloy

DCMT 11T304 GT9530 is an ISO‑standard indexable insert designed for turning and finishing applications in steel, offering a balance of surface quality and extended tool life.

• Cermet coating GT9530 for longer life
• ISO‑standard rhombic DCMT 11T304 geometry
• 0.4 mm corner radius for fine surface finish
• Cylindrical hole with single‑side countersink

High‑quality finishing with a wear‑resistant grade

The GT9530 coated cermet grade is engineered for finishing to light universal turning of steel, delivering a notable improvement in surface integrity and edge stability under steady cutting conditions. The small 0.4 mm corner radius and the rhombic seating result in a refined machined face and reduced need for secondary operations. For production environments where consistent dimensional accuracy and repeatable surface finish matter, this grade reduces downtime associated with frequent insert changes and stabilises process output.

Reliable fit and straightforward system integration

Manufactured to ISO specifications, the insert’s DCMT geometry and nominal size simplify holder selection: compatibility is determined by form, clearance angle, tolerance class, fastening method, overall size and thickness. The 3.97 mm thickness and the cylindrical hole with a single‑side countersink (40°–60°) ensure secure clamping and positive location in matching external holders or boring bars. A complete cutting system comprises the indexable insert, an appropriate external holder or boring bar, a locating pad/clamping set and replacement screws, allowing efficient tool replacement and consistent clamping integrity.

Process benefits and application guidance

A single‑sided chipbreaker on this insert supports stable chip control in finishing cuts, reducing the risk of re‑cutting and improving surface consistency. The cermet substrate provides a hard, wear‑resistant edge that maintains sharpness for superior finish, while the coating enhances resistance to abrasive wear—resulting in longer tool life under recommended conditions. For optimal results select the chipbreaker and grade according to workpiece stability, feed and depth of cut; the insert excels where a high‑quality surface and predictable performance are priorities.

FAQ

What materials is this insert intended for?
The GT9530 coated cermet insert is intended primarily for turning steel, particularly in finishing and light universal operations where a good surface finish and longer tool life are required.

What is the full designation and how is it identified?
The insert is designated DCMT11T304 GT9530 (Article number 6723191, SKU TUN6723191) and is identifiable by its rhombic shape, 11 size, 0.4 mm corner radius and the GT9530 coated cermet grade.

Which holder characteristics are required for compatibility?
Compatibility depends on matching the insert’s form, 7° clearance angle, tolerance class, fastening style, size and 3.97 mm thickness; ISO‑compliant turning holders and boring bars with corresponding clamping arrangements are suitable.

How does the GT9530 grade affect machining results?
GT9530 provides a wear‑resistant cutting edge with improved surface integrity and prolonged edge life under stable cutting conditions, reducing the frequency of insert changes and improving process consistency.

Is this insert suitable for heavy roughing operations?
This grade and geometry are optimised for finishing to light universal turning rather than heavy roughing; for roughing applications, a more robust geometry and grade should be selected.
