TCGT 110301 J740 — Tungaloy indexable turning insert for Turning, triangular, 7° clearance

A TCGT110301 J740 indexable turning insert designed for ISO-compliant external and internal turning, offering a compact triangular form and a balanced mix of wear resistance and edge stability.

• ISO-compliant triangular insert
• J740 grade for wear resistance
• 0.1 mm nose radius for fine finishes
• Secure clamping with cylindrical hole
• 7° relief for versatile cutting

Improved process reliability with a wear-resistant grade

The combination of J740 and a carbide substrate gives a predictable balance of hardness and toughness, translating into steady tool life and fewer unplanned tool changes. In production environments where uptime matters, the reliable wear performance reduces interruptions and supports repeatable component tolerances. The ISO-based geometry ensures compatibility with a wide range of holders when form, relief angle, tolerance class, fastening and thickness are matched, which simplifies tool inventory and supports efficient set-ups.

Precise geometry for consistent surface quality

Designed with a 60° triangle and a 0.1 mm nose radius, this insert delivers repeatable finishes on profile and facing operations. The 7° clearance angle and 3.18 mm plate thickness provide a stable cutting edge under both light and moderate interrupted cuts. A cylindrical hole with single-sided countersink (40°–60°) secures the tip in the clamp and helps maintain concentric seating, which is particularly useful for fine internal work or when using smaller-diameter boring bars. These geometric details make it easier to predict cutting forces and to achieve the targeted surface quality.

Practical selection and system integration for turning tasks

For most external or internal turning tasks the chipbreaker and grade should be selected to match workpiece material and machining stability; the single-sided chipbreaker is suitable for conventional turning directions. The insert is part of an ISO system consisting of the indexable plate, an appropriate external holder or boring bar, a shim/clamping set and replacement screws. This modular approach enables rapid replacement and consistent clamping. If finer advice is required for a specific application or material pairing, technical consultation is available to support optimal grade and chipbreaker choice.
