DNMG150404 GT9530 ISO turning insert for turning applications, Tungaloy, 55°

The DNMG150404 GT9530 is a coated cermet ISO turning insert engineered for finishing and light universal turning of steel under stable machining conditions.

• Coated cermet GT9530 for longer tool life
• ISO DNMG geometry for external and internal turning
• 55° rhombic form with 0° clearance angle

High-precision finishing through cermet technology

The coated cermet GT9530 grade combines a wear-resistant surface with fine, stable chip formation to produce improved surface finish and extended edge life compared with conventional grades. In finishing and light general turning of steel, the microstructure of the cermet reduces built-up edge and supports lower cutting forces at moderate feeds, which helps to maintain dimensional accuracy. The rhombic DNMG geometry with a 55° approach angle and 0° clearance angle is optimised for both external and internal turning where radial engagement and rigidity are key. The result is fewer part rework cycles and a more predictable production output.

Compatibility and economical indexing for production workflows

As an ISO turning insert, compatibility with the holder is governed by form, free rake angle, tolerance class, fastening and thickness — the system consists of the insert, a suitable external holder or boring bar, a seat or clamp set, and replacement screws. The double-sided chipbreaker and two-sided cutting capability allow economical indexing, effectively doubling usable edges and reducing tooling cost per part. The insert’s dimensions — including the 0.4 mm corner radius and 4.76 mm plate thickness — support stable engagement in well-supported setups, while the cylindrical hole simplifies secure fixing in standard clamps.

Material application and practical selection advice

This grade is optimised for steel machining where a combination of good surface quality and longer tool life is required under stable cutting conditions. For best results, select a chipbreaker and insert grade matched to the workpiece alloy and the planned cutting parameters: the GT9530 is a wear-resistant finishing-to-light-universal grade suited to steels rather than highly interrupted cuts or unsteady setups. The 15 mm inscribed size and modest corner radius favour fine finishing passes; larger radii or more robust grades are recommended for roughing. If holder compatibility or geometry choice is unclear, the technical team can advise on the correct clamp and screw combinations to preserve repeatability and surface integrity.

FAQ

What materials is this insert intended for?
The GT9530 grade is intended primarily for steel machining; the DNMG150404 insert performs best in finishing and light general turning applications on steel.

Can the insert be used for internal turning as well as external turning?
Yes — the ISO DNMG150404 geometry and 55° approach angle make the insert suitable for both external and internal turning when matched with an appropriate holder.

How does the coated cermet GT9530 compare to conventional carbide in finishing?
The GT9530 coated cermet offers improved surface finish and resistance to built-up edge in finishing operations compared with many conventional carbides, extending effective edge life under stable conditions.

How many usable edges does the insert provide?
The insert is double-sided with a two-sided chipbreaker, enabling multiple indexing positions to maximise usable cutting edges and reduce tooling cost per edge.

Which dimensions are critical when checking holder compatibility?
Critical dimensions include the inscribed size (15 mm), plate thickness (4.76 mm), corner radius (0.4 mm) and the DNMG form; the hole style (cylindrical) must match the holder clamp system.
