DNMG150402 T9225 — ISO rhombic indexable insert for turning by Tungaloy

The DNMG150402 is an ISO-standard rhombic indexable insert engineered for turning operations, offering a tough CVD-coated cemented carbide grade suited to medium to heavy steel machining.

*DNMG150402 geometry for versatile turning *CVD-coated cemented carbide grade T9225 for toughness *0° relief and 55° lead angle for stable cutting *Double-sided chipbreaker with central cylindrical hole for clamping

Durable cutting performance that reduces tool changes

The combination of a CVD-coated surface and cemented carbide substrate in the T9225 grade provides enhanced resistance to thermal wear while retaining increased toughness for interrupted cuts. This balance of properties translates into fewer tool changes and more consistent component quality during medium to heavy steel machining. The insert’s robust grade is designed to maintain a stable cutting edge under varying engagement conditions, which supports productivity and process reliability in batch and continuous turning applications.

Stable clamping and ISO compatibility for predictable setup

The rhombic plate form with a 55° lead angle and 0° relief creates a cutting geometry that reduces radial forces and supports accurate dimensioning on external and internal turning operations. With a plate thickness of 4.76 mm, a size of 15 mm and a 0.2 mm corner radius, the insert sits securely when used with a suitable external holder or boring bar; compatibility depends on matching the holder’s form, relief angle, tolerance class, fastening and plate size. The double-sided chipbreaker and the central cylindrical hole provide secure clamping and economical indexing, offering two usable edges per side to extend service life and lower tooling costs.

Practical selection advice to increase uptime

For best results with medium to heavy steel work, pair the insert’s T9225 grade with a chipbreaker suited to the intended feed and depth of cut; the double-sided design allows flexibility for finishing or roughing by selecting an appropriate cutting edge orientation. When conditions include slight interruptions, the increased toughness of the grade helps prevent premature fracture and improves process stability. For assembly, use the recommended underlay or clamp set and replacement screws matched to the holder; this ensures repeatable clamping force and consistent tool life. Technical consultation is available for selecting feeds, speeds and coolant strategies to match the machining scenario.

FAQ

What materials is the DNMG150402 T9225 best suited for?
The DNMG150402 T9225 insert is optimised for medium to heavy steel machining thanks to its CVD-coated cemented carbide composition and robust chipbreaker design.

How does the 0.2 mm corner radius affect performance?
A 0.2 mm corner radius on the DNMG150402 increases edge strength for interrupted cuts and heavy engagement, improving tool life while maintaining acceptable surface finish.

Can the insert be used for both external and internal turning?
Yes, the rhombic geometry and 55° lead angle make the DNMG150402 suitable for both external and internal turning when paired with the correct holder and clamping arrangement.

How is the insert secured in the holder?
The insert features a central cylindrical hole and is intended to be used with an appropriate underlay/clamp set and replacement screws to ensure secure clamping and repeatable positioning.

What is the advantage of the double-sided chipbreaker?
The double-sided chipbreaker on the DNMG150402 provides two effective cutting edges per side, supporting economical indexing and flexibility between roughing and finishing operations.
