DCGT 070200 J740 ISO turning insert (rhomboid, 55°) by Tungaloy

The DCGT070200 J740 is an ISO‑standard rhomboid turning insert designed for external and internal turning, offering a 7° relief and a single‑sided chipbreaker for controlled chip formation and stable cutting.

• ISO‑standard rhomboid insert
• J740 Tungaloy grade for wear resistance
• 7° relief angle for consistent cutting
• Cylindrical hole with 40°–60° countersink

Engineered to increase productivity through material‑aware design

The insert is manufactured from carbide and specified in the J740 grade to complement the insert geometry with a focus on wear resistance, toughness and cutting‑edge stability. This combination translates into fewer tool changes and more predictable tool life under comparable conditions, reducing the cost per component. The built‑in single‑sided chipbreaker promotes reliable chip control during turning operations, which in turn helps to protect the workpiece surface and the toolholder from unexpected interruptions. For production environments that prioritise uptime, the balanced properties of the grade make the insert a pragmatic choice for repeatable performance.

Accurate fit and secure clamping for repeatable surface quality

Compatibility with holders is defined by the insert form, relief/clearance angle, tolerance class, attachment method, size and thickness. The rhomboid shape with a 55° cutting angle provides a favourable approach for both profiling and general turning, while the 7° relief reduces rubbing and heat build‑up. The central cylindrical hole with a single‑side countersink (40°–60°) ensures a positive seating and secure clamping, helping to minimise vibration and to maintain a steady cutting geometry. With a 2.38 mm thickness and size 07, the insert suits setups where rigid clamping and controlled overhang are crucial for achieving consistent surface finishes.

Application guidance that supports decision‑making on the shop floor

This indexable insert is intended principally for turning; when selecting inserts from the ISO series, match the chipbreaker and the J740 grade to the workpiece material and the machining stability available. The grade’s emphasis on a balance between hardness and toughness is advantageous when a stable cutting edge is required across medium to heavy interrupted cuts or when prolonged tool life is a priority. Where holder compatibility or process parameters are uncertain, a short consultation with a tooling specialist will quickly identify the appropriate clamping seat and cutting data to exploit the insert’s strengths and to avoid avoidable wear modes.

FAQ

What turning tasks is this insert best suited for?
The DCGT 070200 J740 insert is designed for external and internal turning where a balance of wear resistance and edge stability is required; its rhomboid 55° geometry and single‑sided chipbreaker make it appropriate for general finishing and medium‑duty machining.

How does the J740 grade affect tool life and performance?
The J740 Tungaloy grade enhances the insert’s wear resistance and toughness, producing a stable cutting edge that extends tool life under varying chip loads and reduces the frequency of index changes.

Which holder features must be checked for correct fitment?
Ensure the holder matches the insert form, 7° relief, tolerance class, attachment style, size 07 and thickness 2.38 mm; the cylindrical hole with a 40°–60° countersink requires compatible clamping seats for secure mounting.

Can this insert handle interrupted cuts or harder materials?
The grade’s focus on toughness and edge stability supports interrupted cuts, but final suitability depends on material, machining parameters and machine rigidity; select chipbreaker and cutting data to match the workpiece and stability.

Is the insert reversible and how many cutting edges are available?
The DCGT rhomboid insert design provides usable edges according to the standard ISO geometry; exact edge count depends on indexable insert orientation and rotation—consult the product specifications for edge indexing details.
