DNMG150402 T9225 Tungaloy turning insert — CVD-coated carbide, 55° rhombic

The DNMG150402 T9225 Tungaloy insert is an ISO rhombic indexable insert designed for external and internal turning applications in steel.

• CVD-coated carbide for durability
• Universal T9225 grade for steel
• Rhombic DNMG shape, 55° cutting angle
• Double-sided chipbreaker, cylindrical hole

Reliable performance for medium-to-heavy steel turning

The combination of a CVD-coated surface and a wear-resistant carbide substrate delivers a robust balance between tool life and toughness. The T9225 grade is engineered as a universal sort for medium-to-heavy steel machining, making it suitable where variable engagement or light interruptions occur. The double-sided chipbreaker promotes consistent chip control under changing cutting conditions, which supports steady material removal rates and reduces unexpected downtime. As a consequence, production runs benefit from improved process stability and predictable wear behaviour.

ISO compatibility and straightforward integration into tool systems

Manufactured to ISO dimensions, the insert integrates with holders and boring bars when compatibility parameters—such as form, 0° relief, tolerance class, clamping method, size and 4.76 mm thickness—match the toolholder. The presence of a cylindrical hole and standardised geometry simplifies replacement and inventory management within ISO-based tool systems. The insert forms part of a complete system that includes the indexable insert, a matched external holder or boring bar, shims/clamping sets and replacement screws, enabling fast, repeatable tool changes and reducing assembly time on the shop floor.

Practical advantages and application guidance

With a 0.2 mm radius and a 55° cutting angle, the rhombic geometry offers a compromise between strength at the cutting edge and surface finish capability for general turning tasks. The rhombic form is versatile for both finishing and light roughing when combined with the correct chipbreaker and cutting parameters. For interrupted cuts or less stable setups, the toughness of the T9225 grade helps maintain edge integrity. When configuring operations, select a chipbreaker and cutting data aligned to the workpiece material; this insert is particularly suited to a broad steel spectrum and will yield high process reliability when paired appropriately with a rigid holder.

FAQ

What materials is this insert intended for?
The DNMG150402 T9225 Tungaloy insert is intended primarily for steel machining and performs well in medium-to-heavy cutting tasks.

Can this insert be used for interrupted cuts?
Yes, the T9225 grade’s toughness and the CVD-coated carbide construction make the insert suitable for interrupted cuts and variable engagement conditions.

How is holder compatibility determined for this insert?
Compatibility depends on the insert form, 0° relief angle, tolerance class, clamping method, size and 4.76 mm thickness; matching these parameters ensures correct fit with the toolholder.

Is the insert reversible or indexable?
The insert is double-sided and indexable, allowing rotation to a fresh cutting edge to extend service life.

Which chipbreaker should be chosen for general turning?
Select a chipbreaker that matches workpiece material, depth of cut and machining stability; the double-sided chipbreaker supplied with this insert is a versatile option for general turning in steel.
