DNMG 150408 GH330 turning insert by Tungaloy — ISO DNMG, 55°

A DNMG150408 GH330 indexable turning insert for external and internal turning in ISO tool systems, offering a balanced mix of wear resistance and edge stability.

• ISO DNMG 150408 geometry for universal turning
• GH330 Tungaloy grade for wear resistance
• 0° clearance with 0.8 mm corner radius
• Double‑sided chipbreaker, cylindrical centre hole

Extended tool life through a purpose‑built grade

The GH330 grade from Tungaloy is formulated to provide a reliable balance between wear resistance and toughness for turning applications. This composition reduces flank and crater wear under typical machining parameters, which in turn supports longer intervals between indexings and minimises tool change‑over downtime. The grade's stability at the cutting edge helps to maintain dimensional accuracy over extended runs, delivering predictable productivity and lower overall machining costs.

Geometry engineered for versatile turning performance

The rhombic ISO DNMG form with a 55° included angle and 0° clearance is suited to a wide range of external and internal turning tasks. A 0.8 mm corner radius improves edge strength where interrupted cuts or heavier feeds are required, while the 55° geometry offers a good compromise between approach angle and cutting force distribution. These geometric choices translate into consistent surface finish and reliable chip formation when the correct chipbreaker and process parameters are selected.

System compatibility and secure clamping for repeatable results

Compatibility with clamping systems depends on insert form, clearance angle, tolerance class, fastening method, size and thickness; this insert is supplied as an ISO‑format indexable plate and is intended to be used with matching external holders or boring bars plus the appropriate shim and screw set. Correct pairing of insert and holder ensures secure seating, repeatable location and optimum heat dissipation. Where necessary, select a holder that matches the insert thickness of 4.76 mm and the rhombic profile to preserve cutting geometry and minimise vibration.

Practical advice for selecting chipbreaker and application setup

This double‑sided insert features a double‑sided chipbreaker; choose the chipbreaker and grade combination according to workpiece material, cutting direction and machine stability. For higher feeds or interrupted cuts the larger corner radius grants greater edge resilience, while smaller radii favour finer surface finish. The ISO format simplifies replacement and inventory management, allowing a rapid swap to restore cutting performance and keep production moving.
