DCET 11T302 SH730 (Tungaloy) — ISO rhombic turning insert for general turning

A DCET 11T302 SH730 is an ISO‑standard rhombic turning insert designed for external and internal turning operations, offering a balance of edge stability and versatility for variable engagement conditions.

• ISO rhombic turning insert, ISO 11T302
• SH730 coated carbide for edge stability
• 7° clearance angle for reliable cutting
• 0.2 mm corner radius, with centre hole and 40°–60° countersink

Stable cutting performance for variable engagement

The combination of the SH730 coating and the underlying coated carbide substrate is optimised for edge retention under changing cutting conditions. This grade is described as a tough, edge‑stable variant particularly suitable for smaller tool geometries and variable depths of cut; the result is fewer unexpected interruptions and steadier productivity. The design targets shops seeking a compromise between tool life and process stability while machining a wide range of turning tasks.

Predictable fit and secure clamping for ISO toolholders

Compatibility with holders is governed by form, free angle, tolerance class, fastening method, size and thickness. The ISO 11T302 designation and rhombic geometry make the insert straightforward to match to standard external holders and boring bars, while the centre hole with a cylindrical bore plus one‑sided countersink (40°–60°) ensures reliable mechanical clamping. This predictability reduces setup time and helps maintain repeatable positioning in multi‑insert tool assemblies.

Geometry that balances finish and tool life

The 0.2 mm corner radius combined with a 55° included angle provides a compromise between surface finish and edge strength: small radii aid finer finishes, while the rhombic form and 7° clearance preserve cutting edge stability during interrupted cuts. The plate thickness of 3.97 mm contributes to insert rigidity, which supports dimensional accuracy and reduces vibration in less rigid set‑ups. Where a finer or rougher finish is required, the geometry allows straightforward selection of an alternative radius or insert grade.

Chip control and system advantages for efficient turning

A single‑sided chipbreaker paired with the SH730 grade helps form controlled chips in many turning applications, particularly where engagement varies. The insert forms part of a system comprising a matching external holder or boring bar, clamping plate and replacement screws; this modular approach enables straightforward inventory handling and quick reconditioning during tool changeovers. The overall effect is improved process reliability and economical use of cutting edges in serial production.
