DCMT070202 GH730 Tungaloy indexable insert for turning — rhombic ISO insert, 0.2 mm corner radius

The DCMT070202 GH730 is an ISO‑standard rhombic indexable insert designed for external and internal turning; its geometry, relief and thickness must match the chosen holder for reliable clamping and predictable cutting behaviour.

• ISO-standard rhombic geometry
• GH730 Tungaloy grade – wear-resistant
• 0.2 mm corner radius for fine surface finish
• Central hole with 40°–60° countersink for clamp

Reliable cutting performance for productive turning

The combination of the GH730 composition from Tungaloy and a carbide substrate provides a measured balance of wear resistance and toughness, supporting sustained cutting cycles under typical turning conditions. The single‑sided chipbreaker offers controlled chip formation for many basic turning tasks; the modest corner radius helps to produce a consistent surface finish while reducing edge chipping risk. These technical choices reduce unplanned tool changes and contribute directly to higher process stability and lower unit costs per component.

Precise fitting and secure clamping reduce setup time

Designed as an ISO insert in size 07 with a rhombic 55° included angle, the geometry of the plate must be matched to the holder by form, relief, tolerance class, attachment and thickness for correct fit. The plate thickness of 2.38 mm and a 7° relief angle ensure compatibility with a wide range of ISO external holders, while the central cylindrical hole with one‑sided countersink (40°–60°) gives secure mechanical clamping and consistent seating. This combination simplifies replacement, lowers positioning error and improves repeatability when multiple edges are indexed.

Practical application advice to optimise throughput

As an indexable insert, the DCMT070202 is intended for general turning tasks — external and internal operations where an economical, reproducible cutting edge is required. Multiple indexing extends usable life and keeps spindle downtime to a minimum. For best results, pair the insert with a holder that matches the plate form and stability of the setup, and select a matching chipbreaker and cutting data tuned to the workpiece material and rigidity of the machine. The measured geometry and GH730 grade make this insert a pragmatic choice where reliable edge life and consistent surface quality are priorities.

FAQ

Which operations is this insert designed for?

The DCMT070202 GH730 Tungaloy indexable insert is designed primarily for external and internal turning operations and is compatible with ISO‑type holders when form, thickness and clamping match.

How is the insert clamped in the holder?

Clamping is achieved via the central cylindrical hole with a one‑sided countersink (40°–60°); the DCMT070202 requires the matching screw, clamp or seat geometry in the holder for secure fixation.

What are the key dimensions to consider for holder compatibility?

Important dimensions are thickness 2.38 mm, corner radius 0.2 mm, size 07, relief angle 7° and the 55° rhombic geometry; these determine compatibility with ISO holders and clamping systems.

How should the chipbreaker and grade be chosen?

Select the chipbreaker and grade to suit the workpiece material, machining type and machine stability; the GH730 grade in this insert emphasises a balance of wear resistance and toughness for general turning.

Can the insert be indexed to use multiple cutting edges?

Yes, as an indexable insert the DCMT070202 can be rotated to present fresh edges, extending usable tool life and reducing replacement frequency.
