DCGT 070201 J740 Wendeplatten - Tungaloy

The combination of the J740 carbide grade and ISO rhombic geometry provides a balance of wear resistance and edge stability for productive turning. Compatible mounting features — including a cylindrical hole with a single‑sided countersink and a 0.1 mm corner radius — ensure reliable clamping and repeatable results; order directly via Metav Werkzeuge or consult our advisors for application support.

DCGT 070201 J740 turning indexable insert (ISO 070201) — Tungaloy

The DCGT070201 is an ISO‑standard rhombic turning insert designed for external and internal turning, offering a robust carbide composition and a balanced chip control solution for general turning applications.

• Tungaloy J740 grade for wear resistance
• Rhombic 07 geometry, 55° cutting angle
• 0.1 mm corner radius for fine finishing
• Cylindrical hole with single‑sided countersink

High productivity through wear‑resistant carbide and J740 composition

The J740 designation denotes a Tungaloy carbide grade developed to combine wear resistance with sufficient toughness for many turning tasks. In practice, this means longer edge life under intermittent cutting and stable flank behaviour during continuous cuts. By using a grade that suppresses abrasive wear while still resisting chipping, the insert supports more productive cycles and reduces the frequency of index changes. The choice of this composition is particularly useful where consistent tool performance contributes directly to process economy and predictable cycle times.

Secure mounting and ISO compatibility for predictable results

Designed to ISO specifications, the insert’s form, clearance angle (7°), tolerance class, size and thickness determine holder compatibility. The rhombic 07 format combined with a 55° included angle and a cylindrical hole with a one‑sided countersink (40°–60°) enables secure clamping in many standard external holders or boring bars. The plate thickness of 2.38 mm and the 0.1 mm corner radius ensure the cutting edge sits accurately in the pocket and that clamping forces are transmitted evenly, which reduces micro‑movement and maintains dimensional consistency across serial production.

Practical guidance on applications and chip control

This insert is intended for turning operations where chip formation and edge stability must be balanced. The one‑sided chipbreaker requires selection according to workpiece material and the chosen cutting parameters: a chipbreaker optimised for intermittent cuts and mixed materials will improve evacuation and reduce rework. While the chemistry and microstructure of the grade provide broad usability, pairing the insert with a matching chipbreaker and appropriate cutting data yields the best surface finish and tool life, particularly in general‑purpose machining where versatility matters.

System setup, replacement parts and operational benefits

An efficient system comprises the ISO insert, a matching external holder or boring bar, a supporting shim or clamping set, and replacement screws. Using standardised replacement components simplifies maintenance and reduces downtime. The insert’s carbide substrate and J740 characteristics promote stable edge geometry, which in turn eases process monitoring and reduces scrap. For shops aiming at steady, reproducible results, integrating this insert into an ISO‑based toolholding strategy supports predictable service intervals and clear spare‑part lists.

FAQ

What machining operations is this insert intended for?
The DCGT070201 insert is intended for external and internal turning operations; the J740 grade complements the geometry for balanced wear resistance and edge stability during turning.

Which dimensions are critical when selecting a holder for this insert?
Holder compatibility is determined by shape, clearance angle, tolerance class, fastening, size (07) and thickness (2.38 mm); the cylindrical hole and countersink must match the clamping system.

How does the J740 grade influence tool life and performance?
Tungaloy’s J740 grade is formulated to provide a compromise between hardness and toughness, resulting in improved wear resistance and stable cutting edges that support longer indexed life under typical turning loads.

Can the insert be used for fine finishing with a small corner radius?
Yes — the 0.1 mm corner radius is suitable for fine finishing passes and helps achieve a finer surface while maintaining acceptable edge strength for general turning.

What auxiliary components are needed to install the insert correctly?
A matching ISO external holder or boring bar, a supporting shim/clamping set and appropriate replacement screws are required to ensure secure, repeatable clamping and stable machining.
