DCMT11T308 GH730 — ISO turning insert (rhombic, 55°) by Tungaloy

A DCMT11T308 GH730 ISO rhombic indexable turning insert for external and internal turning, designed to deliver consistent chip control and edge stability in general turning applications.

• Tungaloy GH730 for wear resistance and edge stability
• ISO rhombic insert, 55° cutting angle
• 0.8 mm corner radius for versatile turning
• Cylindrical hole + one‑sided 40°–60° countersink

Reliable cutting performance for production turning

The insert combines the GH730 grade with a precision geometry to provide a predictable balance of wear resistance and toughness. As a result, machining cycles benefit from fewer interruptions due to edge failure and from stable tool life, which supports longer uninterrupted runs on CNC lathes. The rhombic 55° shape and the modest 0.8 mm corner radius enable a mix of finishing and light roughing operations while preserving part tolerances and surface integrity.

Compatibility and fixture security reduce set-up time

This ISO indexable insert is supplied in the widely used DCMT format and is designed for use with standard external holders and boring bars; compatibility depends on form, relief angle, tolerance class, fixing method, size and plate thickness. The cylindrical hole with one‑sided countersink (40°–60°) ensures secure clamping and precise seating, reducing the risk of micro‑movement under cutting forces and simplifying insert replacement during set-up changes.

Practical geometry for consistent chip formation and finish

The single‑sided chipbreaker geometry suits a range of turning tasks where predictable chip flow is essential. Combined with the cemented carbide substrate and the controlled free clearance of 7°, the design promotes regular chip breakage and helps maintain a steady surface finish. Where batch consistency and repeatability are priorities, this insert offers a pragmatic compromise between robustness and fine finishing capability.

FAQ

Is this insert suitable for both external and internal turning?
The DCMT11T308 GH730 Tungaloy indexable turning insert is intended for external and internal turning; holder compatibility is determined by form, relief angle, tolerance class, fixing, size and thickness.

Which materials is the GH730 grade aimed at?
The GH730 grade on the DCMT11T308 provides a balanced combination of wear resistance and toughness for a broad range of general turning tasks where edge stability and predictable wear behaviour are needed.

How does the hole and countersink affect clamping?
The cylindrical hole with a single‑sided 40°–60° countersink on the DCMT11T308 improves seating and clamp stability, reducing the likelihood of micro‑movement during cutting and aiding repeatable tool positioning.

What does the 0.8 mm corner radius mean for machining?
A 0.8 mm corner radius offers versatility: it supports light roughing and finishing while reducing the risk of chipping compared with very small radii, contributing to consistent surface finish and tool life.

What are the article and SKU references for ordering?
