DNMG150612 T9225 ISO turning insert for medium to heavy steel turning — Tungaloy

A DNMG150612 T9225 ISO rhombic indexable insert designed for turning applications, offering a sturdy nose radius and a universal chipbreaker for varied engagement conditions.

• DNMG 150612 form, 55° cutting geometry
• CVD-coated carbide T9225 for steel
• 1.2 mm nose radius for robust edge strength
• Double-sided chipbreaker, cylindrical hole for secure clamping

Higher productivity through a robust universal grade

The combination of a CVD-coated carbide substrate and the T9225 grade targets a balance between wear resistance and toughness, which is essential for medium to heavy steel turning. The coating reduces flank wear and improves tool life under variable engagement, while the substrate maintains edge stability when cuts are slightly interrupted. This results in fewer indexings and longer uninterrupted production runs, translating into measurable productivity gains on the shop floor.

Geometry and edge design that reduce rework

With a 55° rhombic shape and a 1.2 mm nose radius, the insert delivers a stable cutting edge and improved cutting force distribution. The geometry helps to maintain dimensional accuracy and surface finish during external and internal turning operations. The double-sided chipbreaker is optimised for general-purpose steel machining, controlling chip formation to lower the risk of built-up edge and to simplify chip evacuation, which reduces secondary operations and rework time.

Fast, reliable setup and secure clamping

The insert is ISO-standardised for compatibility with a wide range of external holders and boring bars; compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness. The insert includes a cylindrical hole for positive location and repeatable clamping, while the 6.35 mm plate thickness and 15 mm inscribed circle provide the mechanical stability expected in heavier cuts. Clear, standardised mounting reduces setup time and minimises variability between operators.

Application guidance and selection tips

For general steel turning, the T9225 grade is recommended where interrupted cuts or varying engagement demand additional toughness without sacrificing wear resistance. Select the nose radius and feed to match the required surface finish and component tolerances: the 1.2 mm edge is a good compromise for strength and finish. Where higher surface finish or lighter cuts are needed, consider smaller radii or fine finishing passes. If further material-specific optimisation is required, technical consultation is available to align grade, chipbreaker and cutting data to the machining scenario.

FAQ

What materials is this insert suitable for?
The DNMG150612 T9225 insert is formulated for machining steel; the T9225 grade provides robustness for medium to heavy steel turning.

How does the T9225 grade perform with interrupted cuts?
The CVD-coated carbide T9225 offers increased toughness compared with purely wear-focused grades, improving resistance to chipping during interrupted cuts.

What clamping method suits this insert?
The insert uses a cylindrical hole and standard ISO geometry for secure location in compatible external holders and boring bars, ensuring repeatable clamping.

Can this insert be used for finishing operations?
With its 1.2 mm nose radius, the insert is optimised for general turning; fine finishing may require a smaller radius or a dedicated finishing grade and cutting data adjustments.

Is the insert reversible or single-use per edge?
This is a double-sided indexable insert, allowing both cutting edges to be used before replacement or re-grading, which supports cost-effective tool life management.
