DCMT11T302 GT9530 — Tungaloy turning insert, coated cermet for finishing

DCMT11T302 GT9530 is an ISO-format rhombic insert designed for finishing and light universal turning on steel, combining a coated cermet grade with a single-sided chipbreaker for reliable surface quality.

• Coated cermet GT9530 grade for finishing
• Rhombic form with 55° included angle
• Single-sided chipbreaker for stable chips
• 0.2 mm corner radius for fine edges

Delivering a consistent finish and extended tool life

The GT9530 coating in a coated cermet formulation is engineered for wear resistance during finishing operations, translating into stable component surfaces and fewer tool changes. In practice, this grade is suitable for turning steel components where improved surface quality is required under steady machining conditions. The combination of a fine 0.2 mm corner radius and a dedicated chip control geometry helps maintain edge integrity and reduces the frequency of rework, supporting uninterrupted production cycles.

Predictable fitment and mounting for ISO tooling systems

Produced to ISO dimensions, the insert’s rhombic shape and 55° included angle ensure compatibility with standard holders when form, clearance, tolerance class, fastening method, size and thickness match. The 7° clearance and 3.97 mm plate thickness contribute to secure seating and mechanical stability. The centre cylindrical hole with a single-side countersink (40°–60°) provides straightforward clamping and replacement, enabling rapid toolset changes and consistent concentricity in both external and internal turning setups.

Productivity advantages through reliable chip control

The single-sided chipbreaker design manages swarf effectively in finishing passes, which reduces downstream cleaning and machine stoppages. Under stable process conditions the GT9530 grade offers longer tool life relative to uncoated finishing grades, thereby lowering tool consumption and increasing spindle uptime. Optimised chip formation also supports predictable surface metrics, helping to meet inspection criteria with fewer corrective operations.

Practical application guidance and system considerations

As part of an ISO insert system, the item is intended to be used with a matching external holder or boring bar, plus the appropriate shim and clamping set plus replacement screws. The grade is recommended for finishing to light universal turning on standard steels; selection of a compatible chipbreaker and holder depends on component rigidity and machine stability. For optimal results, pair the insert with a stable clamping arrangement and adjust feed to maintain the small corner radius; this approach preserves the edge and preserves surface integrity for subsequent processes.

FAQ

What materials is this insert suited for?
The GT9530 grade is formulated for machining steel in finishing to light universal turning; the DCMT11T302 geometry supports good surface quality when used under stable conditions.

How is the insert clamped in the holder?
The insert uses a cylindrical hole with a single-side countersink (40°–60°) for positive clamping; compatibility depends on matching the holder to the ISO dimensions and fastening arrangement.

Can the DCMT11T302 GT9530 be used for internal turning?
Yes — the rhombic form and chip control suit both external and internal turning provided the boring bar and machine setup offer sufficient rigidity.

What are the key geometry details to check before installation?
Verify the 55° included angle, 7° clearance, 3.97 mm thickness and the 0.2 mm corner radius to ensure correct seating and expected cutting performance.
