DCGT 070201 J740 Wendeplatten - Tungaloy

Reliable wear resistance from the Tungaloy J740 grade combined with ISO conformity, a 0.1 mm corner radius and a secure clamping hole deliver consistent turning performance; order the insert directly via Metav Werkzeuge or ask our consultants if needed.

DCGT 070201 J740 — ISO rhombic turning insert, 55° (Tungaloy)

The DCGT 070201 J740 is an ISO‑standard rhombic indexable insert designed for external and internal turning, equipped with a single‑sided chipbreaker for controlled swarf formation.

• ISO rhombic insert DCGT 07, 55° cutting angle
• Grade J740 carbide for wear resistance and toughness
• Cylindrical hole with single‑side countersink 40°–60°
• 0.1 mm corner radius; thickness 2.38 mm

Consistent cutting performance through material and geometry

The combination of carbide construction and the J740 Tungaloy grade provides a balance of wear resistance and edge stability that supports repeatable turning operations. The rhombic geometry with a 55° cutting angle yields good access for both external and internal contours while the 0.1 mm corner radius helps to fuse surface quality with tool life. For machining processes that demand predictable tool behaviour, this insert reduces variability and maintains component tolerances.

Secure fitting and ISO compatibility for flexible tool setup

As an ISO‑standard insert, the item fits a wide range of holders when matched for shape, relief angle, tolerance class, fastening method, size and thickness. The cylindrical hole with a single‑side countersink (40°–60°) ensures reliable clamping and repeatable seating in the pocket, while the 7° clearance angle supports consistent chip evacuation. When configuring tooling systems, check holder compatibility to preserve the insert’s designed cutting geometry and clamping integrity.

Improved chip control and suited applications

The single‑sided chipbreaker geometry is intended to direct chips and reduce built‑up edge in many common turning scenarios. Combined with the Tungaloy grade, the insert is suitable for a variety of turning tasks; choose the chipbreaker type and grade variant according to workpiece material and machining stability. This approach enhances productivity by lowering downtime for edge dressing and by enabling steadier feed rates where surface finish and component accuracy matter.

Practical guidance for selection and use

Select the insert grade and chipformer according to the workpiece alloy, required surface finish and machine rigidity. The 07 size and 2.38 mm thickness make the insert suitable for general turning applications, from finishing to moderate roughing, when paired with an appropriate holder and clamping set. For process tuning, consider tooling stiffness, feed and depth of cut to protect the cutting edge and extend service intervals; routine visual checks for flank wear and chip shape give clear indicators for optimisation. If additional data or process parameters are required, technical support is available to advise on the best combination for a given application.
