DCGT 11T304 GH330 turning insert — Tungaloy

The DCGT 11T304 GH330 is an ISO rhombic, 55° indexable insert for general turning, designed to balance wear resistance and edge stability in a wide range of turning tasks

• ISO rhombic 55° geometry
• GH330 grade for wear resistance
• 0.4 mm corner radius for fine finishing
• Cylindrical hole with countersink 40°–60°

Geometry engineered for consistent chip control

The rhombic 55° geometry combined with a single-sided chipbreaker produces predictable chip formation and stable cutting forces, which helps to maintain cycle-time consistency on repetitive turning tasks. The moderate 7° clearance angle reduces rubbing on the flank while preserving edge life, and the 0.4 mm corner radius supports high-quality surface finishes in light to medium cuts. Compatibility with holders depends on form, relief angle, tolerance class, clamping and thickness, ensuring repeatable seating when paired with the correct ISO external holder.

Carbide grade that balances wear resistance and toughness

The insert is made from a cemented carbide substrate and finished in Tungaloy's GH330 grade, optimised for turning. This grade emphasises balanced performance: adequate wear resistance for longer tool life under continuous machining and sufficient toughness to resist chipping under interrupted cuts. The result is fewer insert changes, steadier process outputs and improved overall productivity when machining a variety of steels and common ferrous materials.

Practical mounting and ISO compliance for reliable set-up

Designed as an ISO-standard indexable insert, the DCGT 11T304 supports a straightforward system build-up: indexed insert, compatible outer holder or boring bar, support shim/clamping set and replacement fixing screws. Key dimensions are size 11, thickness 3.97 mm and the specified cylindrical hole with single-sided countersink (40°–60°) for secure clamping. These measurable parameters make tool selection and inventory management simpler and reduce the risk of incorrect seating or misalignment during tool changes.

Choosing the right chipbreaker and application matching

Select the single-sided chipbreaker variant in line with workpiece material, cutting conditions and machine stability to extract the maximum advantage from GH330. For fine finishing or tight dimensional tolerances prefer the smaller corner radius; for heavier, interrupted cuts consider a more robust holder and review cutting data accordingly. If uncertainty remains about fitment or grade choice, Metav Werkzeuge’s technical advisors can provide guidance based on the machine, workpiece material and targeted productivity.

FAQ

What materials is this insert suitable for?
The DCGT 11T304 GH330 insert from Tungaloy is designed for general turning and performs well on a broad range of ferrous materials thanks to the GH330 grade’s balance of wear resistance and toughness.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius helps to produce finer surface finishes and reduced vibration in finishing passes; the GH330 grade supports consistent edge stability during these operations.

Which holders are compatible with this ISO insert?
Compatibility is determined by form, relief angle, tolerance class, clamping method, size and thickness; use an ISO external holder sized for size 11 and 3.97 mm thickness to ensure correct seating for the DCGT 11T304.

Is the DCGT 11T304 available with different chipbreakers?
This variant is specified with a single-sided chipbreaker; alternative chipbreaker geometries may be offered depending on cutting strategy and material—refer to technical guidance for selection.
