DCGT 070202 J740 — ISO turning insert for turning by Tungaloy

DCGT 070202 J740 is an ISO‑normed rhombic indexable turning insert designed for general turning applications where secure clamping, consistent edge stability and reliable chip control are required

• ISO indexable format DCGT 070202 J740
• Carbide grade J740 for balanced durability
• 7° clearance angle for stable cutting geometry
• Cylindrical hole with countersink for firm clamping

Precision and consistency for repeatable turning

The DCGT070202 J740 Tungaloy indexable insert combines ISO conformity with a rhombic geometry and a 55° approach angle to deliver consistent chip engagement and predictable forces during external and internal turning. Constructed from carbide, the grade J740 balances wear resistance and toughness, supporting longer tool life where intermittent cuts or variable stability occur. Because compatibility depends on form, clearance, tolerance class, fastening, size and thickness, this ISO reference simplifies selection and reduces setup uncertainty when matching to standard external holders and boring bars.

Faster setups and improved process stability

A secure clamping interface is provided by the cylindrical hole with one-sided countersink (40°–60°); combined with the insert’s 2.38 mm thickness and 0.2 mm corner radius, this yields repeatable seated position and reliable edge support. The single‑sided chipbreaker promotes controlled chip formation on the intended cutting side, reducing risk of entanglement and easing evacuation in continuous turning cycles. These measurable characteristics help shorten changeover time and improve cycle consistency, contributing directly to throughput and lower scrap rates.

Flexible choice for varied machining demands

Presented as part of an ISO insert system, the rhombic shape and moderate clearance (7°) make this turning insert adaptable to a range of holder geometries and workpiece stabilities. The grade selection and chipbreaker type allow process engineers to tailor the cutting edge balance according to specific workpiece materials and machining strategies. Where higher cutting speeds or different materials are required, the insert’s standard designation and grade make it straightforward to select alternate chipbreaker geometries or complementary grades without changing the clamping system.

FAQ

Which machining tasks suit this insert best?
The DCGT 070202 J740 indexable insert is intended for turning operations, both external and internal, where a balance of wear resistance and edge stability is required.

How is the insert secured in the holder?
The insert uses a cylindrical hole with a one‑sided countersink (40°–60°) and is clamped in ISO‑compatible external holders or boring bars; secure seating depends on correct holder form and tolerance class.

What are the key dimensions to check for compatibility?
Important values are the thickness (2.38 mm), corner radius (0.2 mm), insert size (07) and clearance angle (7°); these determine fit and cutting geometry.

What benefit does the J740 grade provide?
The J740 grade from Tungaloy offers a compromise of wear resistance and toughness, helping to maintain cutting edge integrity and consistent performance in varied turning conditions.

Is the chip control suitable for continuous turning?
Yes, the single‑sided chipbreaker on this insert is designed to produce consistent chips for many continuous turning applications, improving evacuation and surface quality.
