The combination of the Tungaloy J740 grade and the 0.2 mm corner radius delivers a balanced mix of wear resistance and edge stability for productive turning. Order the insert directly via Metav Werkzeuge or ask our consultants for a tailored recommendation.

DCGT 070202 J740 – Indexable insert for turning (Tungaloy)

DCGT070202 J740 is an ISO-standard rhombic indexable insert for external and internal turning applications, optimised for stable chip formation and long tool life.

• ISO-standard rhombic insert
• Tungaloy J740 carbide grade
• 0.2 mm corner radius
• 7° relief angle

Greater productivity through matched grade and geometry

The combination of the Tungaloy J740 grade and the rhombic insert geometry enables efficient machining with reliable wear behaviour and edge stability. The carbide composition provides the hardness required for continuous cutting, while the grade’s balance of toughness and wear resistance reduces the risk of premature chipping. For many turning tasks this results in higher material removal rates and fewer indexings, which supports a more consistent production flow.

Secure clamping and straightforward holder compatibility

Compatibility with the toolholder is determined by form, relief angle, tolerance class, fastening, size and thickness; the DCGT070202 conforms to ISO dimensions, simplifying selection of a matching external holder or boring bar. The insert’s cylindrical hole with one-sided countersink (40°–60°) and standard thickness allow secure clamping with common shims and screws, ensuring repeatable seating and stable cutting conditions that reduce vibration and improve surface finish.

Application guidance and material suitability

Select the one-sided chipbreaker and the J740 grade according to the workpiece material and the machining stability required; the insert is intended for general turning of a wide range of materials where a balance of wear resistance and toughness is beneficial. The spec sheet—including the 7° relief angle, 55° cutting edge angle and 0.2 mm corner radius—helps set cutting parameters and predict tool life. When high speeds or specific workpiece alloys are involved, pairing the insert with an appropriate holder and optimised cutting data will yield the best results.

FAQ

What materials is this insert suited for?
The DCGT070202 J740 insert is designed for a broad materials spectrum; the Tungaloy J740 grade combines wear resistance and toughness to handle many common turning tasks.

How does the 0.2 mm corner radius affect cutting?
A 0.2 mm corner radius balances edge strength and detail; it improves edge life compared with smaller radii while still permitting relatively fine dimensional control in turning operations.

Which holders are compatible with this insert?
Compatibility depends on holder form, relief angle and tolerance; the ISO designation and the cylindrical hole with countersink enable use with standard external holders and boring bars that accept DCGT inserts.

What is the purpose of the one-sided chipbreaker?
The one-sided chipbreaker stabilises chip flow for specific cutting directions and materials, reducing built-up edge and improving surface finish when the insert is used under appropriate cutting conditions.

How often should the insert be indexed or replaced?
Indexing frequency depends on workpiece material, cutting data and operating stability; the J740 grade is specified to extend service intervals through its balanced wear and toughness properties.
