DCMT11T304 GH730 turning insert by Tungaloy — rhombic, 7° clearance

A DCMT11T304 GH730 ISO-standard turning insert designed for external and internal turning, offering robust edge stability and reliable chip control in production environments.

• ISO rhombic insert DCMT11T304
• Carbide grade GH730 for wear resistance
• 0.4 mm corner radius for precise profiling
• 7° clearance with cylindrical hole and 40°–60° countersink

Consistent wear life for stable production results

The combination of the GH730 carbide grade and a dedicated cutting geometry provides notable wear resistance while retaining sufficient toughness for interrupted cuts. As an indexable insert, this component concentrates the wear on a replaceable cutting edge, reducing total toolholder costs and simplifying inventory management. The result is a predictable tool life that supports process planning, fewer unexpected stoppages and a more consistent surface finish on workpieces.

Accurate geometry and secure clamping for repeatable parts

The rhombic plate form with a 55° included angle and 7° clearance angle ensures reliable cutting engagement and reduced radial forces during turning. The 0.4 mm corner radius enables precise profiling and controlled cutter contact, which benefits dimensional repeatability and surface quality. The insert’s cylindrical hole with a single-sided countersink (40°–60°) facilitates secure, repeatable clamping in compatible holders and helps maintain consistent cutting geometry across insert changes.

Easy integration into ISO tool systems and flexible chip control

Being an ISO‑standard indexable plate, the insert fits into common external holders or boring bars if the form, relief angle, tolerance class, mounting and thickness match. The one-sided chipbreaker geometry is selected to suit material, machining strategy and machine stability, enabling efficient chip formation and evacuation. This modular approach supports quick replacements, reduces setup time and yields a cost‑effective path to higher throughput in turning operations.

FAQ

What applications is this insert intended for?
The DCMT11T304 GH730 insert is intended for external and internal turning operations and is supplied as an ISO-standard indexable plate for general turning tasks.

Which cartridge grade is used and why is it relevant?
This insert uses the GH730 carbide grade from Tungaloy; the grade balances wear resistance and toughness to deliver stable cutting performance and predictable tool life.

How does the insert fasten to a holder?
The insert features a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping; compatibility is determined by holder form, relief angle, tolerance class, mounting and thickness.

What cutting geometry characteristics improve surface finish?
The rhombic shape with a 55° included angle, a 7° clearance and a 0.4 mm corner radius contribute to controlled cutter engagement and repeatable surface quality.

Is this insert suitable for interrupted cuts and varying stability conditions?
The GH730 grade and the selected cutting geometry give a compromise of toughness and wear resistance designed to withstand varying conditions, including some interrupted cutting; selection of the appropriate chipbreaker further adapts performance.
