DCMT 11T304 GH730 — Tungaloy indexable turning insert, 0.4 mm radius, 7° clearance

The DCMT11T304 GH730 indexable insert designed for machining operations in standard ISO turning systems, offering a balance of wear resistance and edge stability for external and internal turning

• ISO‑standard rhombic insert, 11 mm
• GH730 grade for wear resistance
• 0.4 mm corner radius for versatile finishes
• Cylindrical hole with single-sided countersink

Consistent compatibility for industrial turning

The DCMT11T304 GH730 insert is produced to ISO standard dimensions so that compatibility with holders is predictable: form, clearance angle, tolerance class, fastening and thickness determine the correct match. Using an ISO‑compliant component reduces setup uncertainty and shortens changeover times because available ISO holders and boring bars accept the insert without bespoke adapters. For operations that require quick tool changes and repeatable positioning, this standardisation supports higher uptime and a measurable productivity gain.

Durability and reliable edge life from GH730 carbide

The insert is manufactured from a carbide substrate combined with the GH730 grade, which is engineered to balance wear resistance and toughness. This composition helps maintain cutting‑edge integrity under continuous contact and at elevated temperatures typical of turning. In practical terms, the grade extends time between indexings and replacements, lowering tooling-related downtime. For process planners, the result is a more predictable tool lifetime and reduced intervention frequency during batch production.

Geometry engineered for surface quality and chip control

A rhombic plate form with a 0.4 mm corner radius and 7° clearance produces a combination of accessibility and surface finish suited to a range of turning tasks. The modest corner radius permits finer profile work and improved edge strength for light to medium cuts; larger radii are typically chosen for heavy roughing. The insert’s single-sided chipbreaker steers chips away from the cut and stabilises cutting forces, while the cylindrical hole with single-sided countersink (40°–60°) ensures secure clamping and consistent seat geometry. These features together support improved surface integrity and fewer interruptions for chip clearing.

System integration and operational advantages

This item is intended to form part of a complete turning system: an ISO indexable insert, the corresponding outer holder or boring bar, a seat/clamping kit and replacement screws. The 3.97 mm plate thickness contributes to stiffness in the tool assembly, helping to maintain radial and axial rigidity under load. For workshop managers, that translates into reduced vibration sensitivity and steadier dimensional results. Selecting the appropriate chipbreaker and insert grade for the workpiece and machining conditions will further enhance process reliability and can deliver lower overall machining costs through longer tool life and fewer reworks.

FAQ

What clamping system is required for this insert?
The DCMT11T304 GH730 indexable insert requires an ISO‑compatible rhombic pocket in the outer holder or boring bar; clamping is effected via the cylindrical hole with the single‑sided countersink.

Which applications suit the GH730 grade best?
GH730 is designed to balance wear resistance and toughness, making it appropriate for general turning tasks where consistent edge life and resistance to abrasive wear are priorities.

Can this insert be used for internal and external turning?
Yes, the insert geometry and standard ISO form allow use in both external and internal turning when paired with the correct outer holder or boring bar.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius provides a compromise between fine profile capability and edge strength, supporting smoother surface finishes on finishing passes while maintaining robustness for moderate cuts.

Is the insert suitable for high‑speed machining?
The carbide substrate and GH730 grade offer good thermal and mechanical resistance; suitability for high‑speed conditions depends on machine, cooling and specific workpiece material parameters.
