DNMG 150404 T9225 indexable insert for turning – Tungaloy

A DNMG150404 T9225 indexable insert designed for medium to heavy steel turning, supplied in an ISO‑standard rhombic form for straightforward integration into ISO holders

• DNMG 150404 geometry, ISO‑standard rhombic insert
• CVD‑coated carbide grade T9225 for steel machining
• 0.4 mm corner radius and 55° wedge angle
• Cylindrical hole and double-sided chipbreaker

High‑performance grade for demanding steel turning

The DNMG150404 insert is produced in a CVD‑coated cemented carbide grade T9225, engineered to combine toughness with wear resistance for interrupted and variable‑engagement cuts. The robust grade is suitable for medium to heavy machining of steel where consistent tool life and secure edge behaviour are priorities. Thanks to the 0.4 mm corner radius, edge strength is increased, reducing the risk of chipping under changing load, and enabling reliable dimension control on turned components.

ISO compatibility and secure mechanical clamping

Supplied in an ISO standard rhombic form, this indexable insert integrates easily with matching external turning holders or boring bars; compatibility depends on form, clearance, tolerance class, fastening method, size and thickness. The insert features a cylindrical hole and a double‑sided chipbreaker, allowing reversible use and simple indexing. The combination of geometry and hole style gives predictable clamping and repeatability when the correct holder and screw are selected, supporting stable setups and minimised downtime.

Process stability and efficient chip control

The combination of the double‑sided chipbreaker and grade design promotes stable chip formation, which reduces heat concentration and improves surface finish with fewer interruptions. The insert’s 55° wedge angle and 0° clearance result in a balanced cutting edge suitable for general turning tasks, delivering consistent cutting forces and good surface integrity. For production environments seeking to raise throughput, the predictable wear behaviour of this component helps to plan insert changes and maintain cycle times.

Practical selection and operational guidance

When choosing an insert for a specific job, match the insert grade and chipbreaker to the workpiece material and machining conditions rather than relying solely on geometry. The T9225 grade performs well across a broad range of steels under variable engagement; pair the insert with an appropriately rigid holder and adjust feed and speed to the component’s stability. If component tolerance, surface finish or interrupted cutting present special challenges, consult technical documentation or request tailored recommendations to confirm the optimum combination of insert geometry and holder.

FAQ

What applications suit this insert best?
The DNMG150404 T9225 indexable insert from Tungaloy is intended for external and internal turning of steel in medium to heavy cutting conditions, with the grade optimised for interrupted or varying engagements.

How does the T9225 grade affect tool life?
T9225, a CVD‑coated cemented carbide, provides a balance of wear resistance and toughness; in many steel turning operations the Tungaloy T9225 grade yields longer, more predictable tool life compared with uncoated grades.

Is the insert reversible and how many cutting edges are available?
The DNMG150404 insert is double‑sided and reversible, offering two usable cutting edges per side for efficient indexation and cost‑effective use.

Which holder features are required for correct compatibility?
Compatibility depends on holder form, clearance, tolerance class, fastening method, size and thickness; ensure the external turning holder matches the ISO rhombic DNMG form and accommodates a 4.76 mm thick insert with a cylindrical hole.

What cutting geometry benefits does the 0.4 mm radius provide?
A 0.4 mm corner radius increases edge strength, improves chip evacuation in heavier cuts and helps maintain dimensional stability on turned parts under fluctuating load.
