DCGT 070204 GH330 Tungaloy — ISO turning indexable insert for external and internal turning, rhombic 55° geometry, 7° clearance

The DCGT070204 GH330 is an ISO‑standard indexable insert designed for precision external and internal turning; compatible holders and fastening parts must be matched by form, clearance angle, tolerance class, attachment and size.

• ISO-standard rhombic insert, size 07
• GH330 grade for wear resistance and edge stability
• 7° clearance and 55° included angle for versatile turning
• Cylindrical hole with single-sided countersink (40°–60°)

Reliable performance from the GH330 carbide grade

The ISO series indexable insert is built from carbide and specified in the GH330 grade to deliver a balance of wear resistance and toughness. This composition supports a stable cutting edge and predictable tool life, making the component suitable for a wide range of turning tasks. Where roughing and finishing demands differ, the grade helps maintain dimensional accuracy while resisting abrasive wear; this reduces downtime for insert changes and supports a steady production rhythm.

Precise geometry and secure mounting for consistent machining

The rhombic form with a 55° included angle and 7° clearance gives a compromise between approach angle and edge strength, suitable for both external and internal operations. The insert features a 0.4 mm radius and a 2.38 mm thickness, with a cylindrical hole plus a single-sided countersink (40°–60°) for positive location and secure clamping. Compatibility with the toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness; the system typically comprises the ISO insert, an appropriate external holder or boring bar, a shim/clamp set and replacement screws.

Practical benefits for workshop productivity and process reliability

Selecting the correct chipbreaker and the GH330 grade for the workpiece material and machining conditions reduces scrap and extends the interval between index changes. The insert’s configuration supports efficient chip control in many turning scenarios; for unstable setups, the grade’s toughness helps prevent premature edge failure, while in stable, high‑feed applications the wear resistance sustains surface quality. The combination of ISO conformity and repeatable geometry simplifies tool inventory management and speeds changeovers on the shop floor.

FAQ

What materials is this insert suited for?
The GH330 grade carbide insert is formulated to balance wear resistance and toughness; material selection for machining should be matched to the GH330 properties and the chosen chipbreaker for the best results.

How is the insert mounted to a toolholder?
The insert uses a cylindrical hole with a single‑sided countersink (40°–60°); secure clamping requires a matching holder or boring bar plus the correct shim/clamp set and fixing screws as per the ISO system.

Which machining tasks are appropriate for this insert?
Designed for both external and internal turning, the insert is suitable for finishing and light to medium roughing when the workpiece, setup and chipbreaker are selected to match the application.

What geometry details affect cutting behaviour?
The rhombic shape with a 55° included angle, 7° clearance and a 0.4 mm corner radius determine approach angle, edge strength and surface finish potential; these parameters should be considered when planning toolpaths.

Is the insert an original Tungaloy part and how is it identified?
The DCGT 070204 GH330 is supplied as an original Tungaloy indexable insert and is identified by article number 6802807 and SKU 6802807‑Tungaloy in our system.
