DCMT11T308 GT9530 Tungaloy indexable insert for turning — 55° rhombic, coated cermet

DCMT11T308 GT9530 is an ISO-standard indexable insert designed for finishing and light universal turning of steel under stable conditions

• DCMT11T308 55° rhombic geometry
• Coated cermet grade GT9530 for finishing
• 0.8 mm corner radius for fine surface finish
• Cylindrical hole with countersink for secure clamping

Consistent finishing and longer tool life thanks to coated cermet technology

The GT9530 coating is a cermet formulation optimised for wear resistance and surface quality in finishing passes on steel. In practice, this means fewer interruptions for insert changes and a reduced need for downstream rework. The 0.8 mm corner radius supports a fine surface finish on external and internal profiles while maintaining adequate edge strength for light to medium cuts. Where a high-quality surface and extended runtime are priorities, the coated cermet composition strikes an effective balance between abrasion resistance and cutting-edge stability.

Secure clamping and straightforward integration into ISO tooling systems

The insert features a cylindrical hole with a single-sided countersink (40°–60°), which ensures precise seating and repeatable clamping when paired with the correct holder. Compatibility with a toolholder is determined by form, relief angle, tolerance class, fastening method, size and thickness; this ISO conformity allows reliable interchangeability with standard external holders or boring bars. The single-sided chipbreaker supports controlled chip flow in finishing operations, reducing the risk of built-up edge under the recommended stable conditions.

Clear benefits for process reliability and part quality

By choosing a finish-oriented grade and a rhombic 55° geometry, the insert helps achieve consistent dimensional accuracy and an improved surface finish on turned components. The coated cermet grade is particularly suited to applications where stable cutting conditions are present—such as reduced tool overhang and rigid clamping—since these circumstances maximise the grade’s advantage in surface integrity and tool life. As a result, production runs can present fewer rejects and more predictable cycle times.

Practical system setup and support for application decisions

The system typically comprises the ISO insert, a matching external holder or boring bar, a shim/clamp set and replacement fixing screws; keeping spare clamps and screws on hand reduces downtime during index changes. For specific workpiece materials or atypical setups, selection of chipbreaker and grade should be matched to cutting parameters and machine stiffness.

FAQ

Is this insert suitable for finishing steel components?
Yes. The DCMT11T308 GT9530 is a finish-to-light universal grade optimised for steel, offering improved surface quality and longer tool life under stable machining conditions.

How does the GT9530 grade differ from general-purpose grades?
GT9530 is a coated cermet grade designed for wear resistance and surface integrity in finishing; it prioritises a fine finish and extended edge life rather than heavy material removal.

What clamping features should the toolholder provide?
A holder that matches the rhombic 55° form, plate thickness and the cylindrical hole with countersink will ensure precise seating and repeatable clamping for secure, vibration-free machining.

Can the insert be used for internal turning as well as external turning?
Yes. The insert is suitable for both external and internal turning when the tool setup provides the necessary rigidity and correct chipbreaker/grade selection for the operation.

What does the 7° relief angle mean for cutting?
A 7° relief angle reduces rubbing behind the cutting edge, aiding surface finish and decreasing friction in finishing cuts when combined with the GT9530 coating.
