TCGT110202 J740 Turning Insert – ISO triangular, 60° by Tungaloy

The TCGT110202 J740 is an ISO-standard triangular turning insert designed for external and internal turning, combining a robust carbide substrate with a one-sided chipbreaker for controlled swarf formation.

• ISO triangular format, 60° included angle
• Tungaloy J740 grade for wear resistance
• 0.2 mm corner radius for fine profiling
• Cylindrical hole with 40°–60° countersink

Stable cutting performance for productive turning

The indexable insert delivers consistent tool life through a balanced mix of hardness and toughness in the carbide substrate. The chosen grade provides improved edge stability under typical turning conditions, reducing unexpected tool changes and improving process reliability. With a 0.2 mm corner radius, the geometry supports fine profiling and repeatable dimensional results while the one-sided chipbreaker helps manage chip flow for uninterrupted production.

ISO compatibility and secure clamping for quick tool changes

Manufactured to ISO dimensions, the triangular geometry ensures compatibility with a wide range of external holders and boring bars; compatibility is governed by form, clearance angle, tolerance class, fastening method, size and thickness. The insert’s cylindrical hole with single-sided countersink (40°–60°) simplifies clamping and repeatable positioning in the pocket. This system approach—insert, suitable holder, shim/clamp set and replacement screws—reduces setup time and supports a stable machining environment.

Material grade explained: reliable carbide with J740 performance

The carbide composition and the Tungaloy J740 designation combine wear resistance and sufficient toughness for general turning duties. This balance is especially relevant when machining a variety of steels and common ferrous alloys, where predictable flank wear and secure cutting edges translate into fewer interruptions and more consistent surface finishes. The substrate and grade selection aim to offer long tool life without sacrificing dimensional accuracy.

Practical applications and handling recommendations

Ideal for both external and internal turning, the insert works well where a controlled chip shape and stable edge are required. The 7° relief angle complements the triangular form for efficient cutting action, while the 11 mm size and 2.38 mm thickness suit standard ISO pockets for medium- to fine-pass operations. For best results, select a chipbreaker and grade matched to the workpiece material and machining stability; this keeps cutting forces consistent and optimises productivity.

FAQ

What materials is this insert suitable for?
The Tungaloy TCGT110202 J740 insert is intended for general turning duties and performs well on common steels and typical ferrous alloys, benefiting from its balanced carbide grade for wear resistance and edge stability.

How is the insert clamped in the toolholder?
Clamping uses the insert’s cylindrical hole with a single-sided countersink (40°–60°); combined with an appropriately matched holder and clamp set, this ensures secure, repeatable seating.

What does the J740 grade mean in practice?
J740 denotes a Tungaloy carbide grade engineered to balance wear resistance and toughness, delivering stable cutting edges and predictable tool life in routine turning operations.

Can this insert be used for both external and internal turning?
Yes, the triangular ISO form and chipbreaker design make the insert suitable for both external and internal turning, provided the holder and process parameters are matched to the workpiece and stability conditions.

Which dimensions determine compatibility with a specific holder?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size (11 mm) and thickness (2.38 mm); ensure the holder pocket matches ISO specifications.
