TCGT 110302 J740 Turning insert by Tungaloy — 7° relief, 0.2 mm radius

The TCGT110302 J740 is an ISO‑standard triangular turning insert designed for general external and internal turning where a balance of wear resistance and edge stability is required.

• ISO triangular insert TCGT 110302 J740
• Tungaloy carbide grade J740 for wear resistance
• 7° relief for stable cutting edge
• Cylindrical hole with 40°–60° countersink

Consistent performance from a wear‑resistant grade

The J740 designation denotes Tungaloy’s carbide formulation optimised for a wide range of turning operations; this grade offers a blend of wear resistance and toughness that reduces unexpected edge breakage. In practice, the optimized substrate and chip control result in longer intervals between tool changes and more predictable component quality, which supports continuous machining cycles and reduces unplanned downtime.

Geometry that supports secure clamping and stable cutting

The triangular outline combined with a 0.2 mm corner radius and a 7° relief produces a dependable cutting geometry for facing and profile turning. The 0.2 mm corner radius gives a compromise between edge strength and surface finish, while the 7° relief helps to reduce rubbing at the flank and keeps cutting forces consistent. These features translate into steady dimensional control and repeatable surface quality during medium to finishing passes.

Mounting compatibility and hole design explained

As an ISO insert, the component fits holders that accept the TCGT form, with compatibility determined by form, clearance angle, tolerance class, fastening style, size and thickness. The insert is supplied with a cylindrical hole and a single‑side countersink (40°–60°) which aids secure locating and straightforward screw clamping. The nominal plate thickness of 3.18 mm ensures sufficient body strength while remaining compatible with common external and boring toolholders.

Practical choice for diverse turning tasks

With a single‑side chipbreaker and the properties of the carbide substrate, this insert performs well across varied steels and common materials encountered in production turning. The standard ISO designation simplifies tool management and replacement cycles in multi‑machine environments, supporting efficient tool inventory and faster set‑ups. For workshops seeking a reliable, general‑purpose turning insert, the balance of edge life and process security makes this a pragmatic choice.

FAQ

What materials is this insert suitable for?
The TCGT110302 J740 insert is formulated for general turning tasks and performs well on a broad range of steels and common engineering materials due to the J740 carbide grade.

Can the insert be used for internal turning (boring)?
Yes, the ISO triangular form and the clamping hole with countersink allow secure mounting in compatible boring bars and holders for internal operations.

How does the 0.2 mm corner radius affect surface finish?
A 0.2 mm corner radius provides a compromise between edge strength and finish quality; it improves edge robustness while still achieving good surface consistency on finishing passes.

Is this insert compatible with existing ISO TCGT holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening style, size and thickness; the insert follows ISO standards for the TCGT form and fits matching holders.

What is the advantage of the J740 grade from Tungaloy?
The J740 grade offers a balanced mix of wear resistance and edge stability, resulting in reliable tool life and consistent machining performance in varied turning applications.
