DNMG150412 T9225 Tungaloy indexable turning insert — ISO turning, 55° rhombic, CVD-coated

The DNMG150412 T9225 is an ISO-standard indexable turning insert for external and internal turning, designed as a robust universal grade for medium-to-heavy steel machining.

• ISO-standard rhombic insert, 55° cutting angle
• CVD-coated carbide grade T9225 for steel machining
• 1.2 mm corner radius for versatile contouring
• Double-sided design with cylindrical locating hole

Reliable productivity through a robust CVD-coated grade

The CVD-coated T9225 carbide grade is formulated for stable chip formation and reliable performance under varying engagement conditions. As a universal solution for medium-to-heavy steel machining, the coated substrate increases resistance to edge breakdown and extends tool life, especially where interrupted cuts or changing cutting forces occur. The result is sustained machining output and fewer insert changes, supporting predictable batch production and reduced downtime.

Seamless integration into ISO tool systems for flexible use

Designed to the ISO DNMG designation, the insert mates with compatible external holders when form, relief angle, tolerance class, fixation, size and thickness match the system requirements. The 55° rhombic geometry and the cylindrical locating hole ensure secure seating and repeatable clamping, while the double-sided configuration provides two productive cutting edges per index. This modular setup — insert, appropriate holder, shim/clamp set and replacement screw — enables quick index changes and consistent setup repeatability across the toolroom.

Practical benefits: versatile contouring and consistent surface finish

A 1.2 mm corner radius delivers a balance between contour capability and edge strength, permitting both finishing passes and moderate stock removal without sacrificing edge stability. In external and internal turning operations the geometry supports improved surface finish and stable cutting forces, contributing to higher overall productivity. The combination of grade, geometry and chipbreaker design reduces rework, helps to maintain cycle times and simplifies grade selection for mixed-series production runs.

FAQ

What materials is this insert best suited for?
The DNMG150412 T9225 insert is specified as a robust universal grade for steel machining; the CVD-coated substrate is optimised for medium-to-heavy turning conditions.

How does the T9225 grade affect tool life?
Tungaloy’s T9225 grade, with its CVD coating, improves resistance to edge wear and supports stable chip control, which together help to extend tool life in interrupted or demanding cuts.

Can this insert be used on internal as well as external turning operations?
Yes, the rhombic 55° geometry and the 1.2 mm corner radius make the insert suitable for both external and internal turning where the holder geometry permits.

What determines compatibility with a turning holder?
Compatibility depends on matching the insert form, relief (facing) angle, tolerance class, fixation method, size and thickness; the DNMG150412 designation ensures ISO conformity for straightforward matching.

How many cutting edges are available per insert?
The plate is double-sided with a cylindrical locating hole, providing two usable cutting edges before indexing or replacement is required.
