DCMT11T302 GH730 — ISO rhombic turning insert for general turning, Tungaloy

DCMT11T302 GH730 is an ISO rhombic turning insert engineered for versatile external and internal turning where a balance of wear resistance and edge stability is required.

• ISO rhombic 55° geometry
• GH730 Tungaloy carbide grade
• Through-hole with countersink
• 0.2 mm corner radius

Durable cutting performance from the GH730 grade

The GH730 grade from Tungaloy is tailored to provide a combination of wear resistance and toughness that suits a wide range of turning tasks. Made of sintered carbide, this grade reduces flank wear and helps maintain a consistent tool life under mixed cutting conditions. For production environments where downtime and rework cost money, the grade’s balanced properties deliver measurable efficiency gains: fewer indexings, steadier surface finish and predictable edge behaviour. The result is a more stable machining process, especially when paired with suitable chipbreaker geometry.

Geometry and holder compatibility for flexible turning

The rhombic design with a 55° point angle offers flexibility for both external and internal turning when the correct holder is selected. The insert is supplied with a through-hole and a cylindrical hole plus one-sided countersink (40°–60°), enabling secure clamping in standard ISO-compatible holders. Note that compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; selecting the correct combination ensures accurate seat contact and repeatable clamping. The single-sided chipbreaker improves chip formation for many light to medium cutting operations and helps to avoid chip entanglement in confined bores.

Practical dimensions and handling for production efficiency

With a nominal size of 11 mm, a plate thickness of 3.97 mm and a corner radius of 0.2 mm, the insert is suitable for finishing and light roughing where small radii and fine surface quality matter. The 7° relief angle and the rhombic profile support predictable cutting forces and allow efficient use of standard holders. For process planners, the compact thickness and standard ISO form simplify stocking and changeover. Where a change in chip control is required, selecting alternate chipbreaker styles or complementary grades can be done without changing established clamping hardware, reducing setup time and inventory complexity.

Application guidance and production benefits

Designed primarily for turning, the insert is ideal for series production as well as single-part machining where consistent edge life is important. The combination of Tungaloy carbide technology and ISO conformity supports high process reliability, reduced tool consumption and stable surface finish—advantages that translate into lower total machining costs and improved shop-floor predictability. For new setups, pairing the insert with a matched external holder, appropriate shim and the correct clamping screw will deliver the expected repeatability in concentricity and cutting performance.

FAQ

Which materials are suitable for this insert?
The DCMT11T302 GH730 insert is optimised for general turning applications and is suitable for a broad range of materials when the correct chipbreaker and cutting data are selected; the GH730 grade balances wear resistance and toughness for many steels and alloyed materials.

Is the insert compatible with standard ISO holders?
Yes, the DCMT11T302 conforms to ISO plate dimensions; compatibility depends on holder form, relief angle, tolerance class and fastening method, so match the insert’s 11 mm size and hole/countersink arrangement to the holder specifications.

What advantage does the 0.2 mm corner radius provide?
A 0.2 mm corner radius offers improved surface finish and reduced cutting forces for finishing passes, while still providing sufficient edge strength for light roughing in many turning operations.

How does the through-hole with countersink affect clamping?
The through-hole plus one-sided countersink (40°–60°) secures the insert centrally and improves seat stability, minimising movement under cutting loads and enabling repeatable positioning in ISO-compatible clamping systems.
