DNMG 110404 T9215 indexable turning insert — ISO rhombic 55° geometry for turning

DNMG 110404 T9215 indexable turning insert designed for external and internal turning applications, offering a balance of productivity and component protection in medium-steel machining.

• CVD-coated carbide T9215 grade
• ISO rhombic DNMG 55° geometry
• Double-sided chipbreaker, with cylindrical hole
• 0.4 mm corner radius for medium steel

High productivity through a wear-resistant grade

The insert features a CVD-coated carbide substrate in T9215 specification, which combines enhanced wear resistance with good fracture toughness to support prolonged cutting cycles. This material-coating combination is particularly effective in continuous and light interrupted cuts, enabling stable tool life when machining medium steel. The selected grade prioritises high removal rates and consistent edge security, so fewer interruptions for tool change contribute directly to improved process throughput.

Geometry and system compatibility for reliable indexing

The DNMG110404 form follows ISO conventions with a 55° rhombic geometry and a nominal 0° relief angle, giving predictable cutting behaviour and straightforward integration into standard holders. Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; the insert’s 4.76 mm thickness and 11 mm inscribed circle make it suitable for many common external holders and boring bars. The item includes a cylindrical locating hole for secure clamping, and the double-sided design effectively doubles available cutting edges per insert, reducing tooling costs and downtime.

Process security, surface quality and application guidance

A 0.4 mm corner radius provides a compromise between strength and surface finish: the larger edge radius reduces edge chipping risk while offering acceptable surface quality on typical steels. The double-sided chipbreaker supports controlled chip formation across a range of feeds, helping to avoid entanglement and promoting stable evacuation. In practice, this insert is specified for turning operations where consistent productivity and predictable wear patterns are required; selection of an appropriate holder and cutting parameters will further enhance life and finish. The construction and coating deliver reliable performance across batch production and single-part runs alike.

FAQ

What materials is this insert intended for?
The DNMG110404 T9215 insert is optimised for medium steel machining; the T9215 grade and CVD coating provide wear resistance and edge security suitable for such applications.

How many cutting edges are available per insert?
The insert offers two usable cutting edges due to its double-sided design, which reduces tooling costs and changeover frequency.

Is the geometry compatible with standard turning holders?
Yes — the DNMG form follows ISO conventions; compatibility depends on holder form, relief angle, tolerance class, fastening and size, with this insert matching common 55° rhombic holders.

What is the corner radius and how does it affect results?
The corner radius is 0.4 mm, which increases edge strength and improves process security while providing a good balance between surface finish and tool life.

Does this insert come with a specific mounting requirement?
The insert uses a cylindrical locating hole for secure clamping; correct seating and the appropriate clamping kit ensure repeatable performance.
