DNMA 150404 GT720 Turning Insert — Tungaloy (ISO DNMA150404, GT720, 55° rhombic)

The DNMA150404 GT720 is an ISO‑standard rhombic indexable insert for finishing and light turning of steel, engineered to deliver high surface quality with a 55° approach angle.

• Cermet GT720 for superior surface finish
• ISO DNMA150404 form for holder compatibility
• 0.4 mm corner radius for fine profiling
• 4.76 mm thickness with cylindrical hole

Optimised surface finish and reliable dimensional control

The DNMA150404 GT720 insert combines a GT720 cermet grade with a rhombic geometry to support finishing and light turning operations where surface finish and dimensional accuracy matter. Cermet substrates deliver a hard, wear‑resistant contact face that resists built‑up edge formation and produces consistent finishes across serial runs. For applications requiring tight tolerances, the uniform wear behaviour of the grade helps maintain part geometry over extended batches, reducing rework and inspection effort.

ISO compatibility for faster tool setup and fewer variables

Designed to the ISO‑standard DNMA150404 form, this indexable insert is compatible with a broad range of DNMA holders and boring bars when matching form, relief angle, tolerance class, fastening and thickness. The rhombic shape with a 55° approach angle offers predictable insert engagement and improved access on external and internal contours. The cylindrical hole and standard thickness ensure secure clamping and repeatable seating, simplifying tool changeovers and minimising setup time across different machines.

Practical productivity: light turning with consistent tool life

The coated cermet construction is targeted at finishing to light‑cut conditions in steel, prioritising steady wear and surface integrity rather than heavy roughing. With a 0.4 mm corner radius the insert is suited to fine profile work and achieving the desired part aesthetics without sacrificing cycle reliability. As part of a complete system—indexable insert, suitable external holder or boring bar, shim/clamp set and replacement screws—this component supports a productive machining flow.

FAQ

What materials is this insert suitable for?
The DNMA150404 GT720 indexable insert from Tungaloy is intended primarily for finishing and light turning of steel, with the cermet grade optimised for surface quality and uniform wear.

Which holder characteristics are required for compatibility?
Compatibility depends on matching the DNMA form, relief angle, tolerance class, fastening method, size and thickness; ensure the holder accepts ISO DNMA150404 inserts for secure clamping of the Tungaloy insert.

Is there a chipbreaker integrated in this insert?
This variant is supplied without a chipbreaker, making it suitable for finishing cuts where chip control is managed by cutting parameters and tool geometry.

What advantages does the GT720 grade provide?
GT720 offers improved surface integrity and steady wear progression in finishing applications, delivering consistent part quality and predictable tool life in serial production.

For which applications is the 0.4 mm corner radius most appropriate?
A 0.4 mm corner radius is recommended for fine profiling and finishing passes where smooth edges and controlled cutting forces are required, helping to improve the final surface without introducing excessive cutting loads.
