DNMG150408 GH330 Tungaloy indexable insert for turning

The DNMG150408 GH330 Tungaloy is an ISO-standard indexable insert optimised for external and internal turning operations, combining a balanced carbide grade with a versatile rhombic geometry.

• DNMG150408 geometry, 55° cutting angle
• GH330 grade for wear resistance and toughness
• Rhombic plate with 0.8 mm corner radius
• Double-sided chipbreaker, cylindrical hole

Longer tool life through balanced carbide grade and cutting-edge stability

The GH330 specification is a Tungaloy carbide formulation developed to combine wear resistance with sufficient toughness, reducing flank wear and preserving the cutting edge during interrupted cuts. In practical terms, this leads to fewer tool changes and more consistent cycle times on the shop floor. When paired with appropriate machining parameters, the insert’s composition supports productive turning where process stability and repeatable results are required.

Secure clamping and ISO compatibility for straightforward tool selection

The ISO DNMG150408 form factor, 55° cutting geometry and rhombic outline make this insert compatible with a wide range of external holders and boring bars. The 0° relief angle, 4.76 mm plate thickness and the cylindrical hole ensure reliable clamping and repeatable positioning in the toolholder. Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; therefore the overall tooling system should include a matching holder or boring bar, a suitable shim/clamp set and replacement screws for secure assembly.

Operational efficiency from chip control and indexable design

The double-sided chipbreaker design enables effective chip control across different cutting conditions and permits economical use of both sides before replacement. The 0.8 mm corner radius contributes to edge strength and can improve surface finish when the machining setup is stable. Together, the rhombic shape and chipbreaker give flexibility for finishing and light-medium machining tasks. For best results, select the chipbreaker and grade according to the workpiece material, machining type and machine stability.

FAQ

What materials is the GH330 grade suited for? The GH330 grade is a Tungaloy carbide formulation that offers a compromise between wear resistance and toughness; in the DNMG150408 GH330 indexable insert this supports reliable performance across a broad range of common turning applications when the chipbreaker and cutting data are matched to the workpiece.

How is holder compatibility determined for this insert? Compatibility depends on the insert form, relief angle, tolerance class, fastening method, size and thickness; the DNMG150408 GH330 is designed for ISO DNMG toolholders and requires a holder that accepts a 15 mm rhombic insert with a 4.76 mm thickness and a cylindrical locating hole.

Can the insert be indexed to use more cutting edges? Yes, the DNMG150408 GH330 insert is double-sided and can be indexed to employ multiple cutting edges, extending the service life before replacement and helping to reduce machine downtime.

What is needed to assemble the insert into a tooling system? A complete system typically comprises the indexable insert itself, a compatible external turning holder or boring bar, an appropriate shim/clamp set and replacement screws to secure the insert in the holder
