VBGT 110302 J740 ISO turning insert for turning — Tungaloy

A VBGT110302FR-J10 J740 indexable insert designed for ISO‑standard external and internal turning with a rhombic geometry and integrated chipbreaker.

• ISO‑compliant rhombic geometry 11 mm
• J740 grade for high wear resistance
• 0.2 mm corner radius for fine finishes
• Cylindrical hole with 40°–60° countersink

Consistent precision and holder compatibility for reliable production

The insert is engineered as an ISO‑compliant indexable insert, which simplifies tool selection and ensures repeatable positioning in standard holders. The rhombic form and the specified dimensions mean compatibility with holders is determined by shape, relief angle, tolerance class, fastening method, size and thickness. This predictability reduces setup time and supports a steady production flow. Where holders differ, selecting the matching shim, clamp set and replacement screw maintains clamping integrity and repeatable machining results.

J740 grade: longer tool life and stable cutting edges

The Tungaloy J740 carbide grade extends tool life through a balanced combination of wear resistance and toughness, supporting longer uninterrupted cycles on both external and internal turning. In practice, this means fewer indexings and reduced downtime for insert changes. The included J10 chipbreaker is matched to the grade and promotes controlled chip formation, which helps preserve the cutting edge and supports consistent part quality across small to medium batch sizes.

Geometry and hole design that improve clamping and chip flow

A 0.2 mm corner radius gives a good compromise between edge strength and the ability to produce fine surface finishes; it is particularly suited to finishing passes where dimensional control is important. The insert’s cylindrical hole with a single‑side countersink (40°–60°) secures the plate evenly in the pocket and simplifies seating in a variety of clamping systems. The specified relief angle of 5° and the stated 35° lead/approach angle contribute to predictable cutting forces and help maintain stability during interrupted cuts.

Materials and applications: what this insert machines well

Made from cemented carbide, the insert is intended for conventional turning operations on a wide range of materials when combined with the right chipbreaker and cutting parameters. The ISO‑standard series supports both external and internal turning tasks; choosing the proper chipbreaker and insert grade tailors performance to the workpiece material and machining stability. For users seeking higher process security and consistent surface finish, this combination offers a dependable solution for general turning applications.

FAQ

What materials is the VBGT110302FR-J10 J740 suited for?
The VBGT110302FR-J10 J740 insert, made of Tungaloy cemented carbide, is designed for a broad range of turning tasks; material-specific performance depends on the selected chipbreaker and cutting parameters.

How does the 0.2 mm corner radius affect surface finish?
A 0.2 mm radius provides improved edge strength while allowing fine surface finishes for finishing passes when the VBGT110302FR-J10 J740 insert is used with appropriate feeds and speeds.

Is this insert compatible with standard ISO holders?
Yes — the insert follows ISO dimensions; compatibility is ensured by matching the holder by form, relief angle, tolerance class, fastening method, size and thickness.

What advantage does the J740 grade offer in production?
The Tungaloy J740 grade balances wear resistance and toughness, resulting in extended tool life and stable cutting-edge behaviour during sustained turning operations.

What is the function of the cylindrical hole and countersink?
The cylindrical hole with a single‑side countersink (40°–60°) secures the insert reliably in the pocket, improving clamp seating and contributing to consistent clamping force and repeatable machining.
