DNGA 150412 BX360 Tungaloy indexable turning insert — CBN grade for hardened steels, 55° rhombic, 1.2 mm radius

The DNGA 150412 BX360 is an ISO‑standard indexable turning insert designed for high‑precision external and internal turning of hardened steels and, depending on variant, selected cast irons; its rhombic 55° geometry delivers stable cutting engagement for fine finishing.

• CBN BX360 for hardened steels and some cast irons
• Rhombic 55° geometry with 1.2 mm corner radius
• ISO DNGA150412 — wide holder compatibility
• No chipbreaker — optimised for finish turning

Stable finishing on hardened materials for consistent part quality

The use of cubic boron nitride (CBN) in the BX360 grade delivers high wear resistance and thermal stability, which translates into extended tool life during abrasive finishing operations. CBN is a superabrasive specifically engineered for machining hardened steels where conventional carbides wear rapidly; the result is a repeatable edge and consistently precise surface quality. Selecting a CBN grade such as BX360 reduces the frequency of index changes and supports predictable production runs, lowering downtime and improving throughput.

Geometry and edge specification that enhance process reliability

The 55° rhombic plate form with a 1.2 mm corner radius offers a balance between strength and accessibility to fine contours. A 0° clearance angle and a plate thickness of 4.76 mm contribute to a rigid cutting edge and controlled chip flow when used with properly matched holders. The DNGA platform conforms to ISO dimensions, so compatibility is governed by form, clearance angle, tolerance class, fixing method, size and thickness — ensuring the insert seats correctly in standard clamping systems and maintains consistent cutting geometry across tool changes.

Designed for system integration and practical use in production

This insert is intended to work as part of a complete system: the indexable plate, a corresponding external holder or boring bar, an underlay/clamp set and replacement screws form the assembly. The presence of a cylindrical locating hole simplifies secure fixation and repeatable positioning. With no integrated chipbreaker, the grade is optimised for finishing passes where surface quality is paramount and minimal edge disturbance is required. The insert’s robust substrate supports high contact loads and stable cutting in demanding serial production.

Productivity benefits and application guidance

By combining a CBN cutting material with ISO‑compliant geometry, the insert enables lower overall tooling costs through longer edge life and fewer interventions. In practice, the DNGA150412 BX360 is best applied to hard turning operations and final passes on heat‑treated components where dimensional stability and surface finish are critical. For integration into existing tool sets, match the insert form and thickness to the holder specification, and select an appropriate clamping kit to ensure repeatable seating and torque control. The predictable wear characteristics of BX360 also facilitate planning of tool change intervals and process control charts.

FAQ

What materials is this insert suitable for?
The DNGA 150412 BX360 insert is primarily designed for hardened steels and, depending on the execution, can also be used for selected cast irons; the CBN BX360 grade provides wear resistance and thermal stability for such materials.

Is this insert suitable for finish turning operations?
Yes. The rhombic 55° geometry, 1.2 mm corner radius and absence of a chipbreaker make the insert particularly well suited to finish turning where surface quality and dimensional accuracy are priorities.

How is the insert secured in the toolholder?
The insert features a cylindrical locating hole and conforms to ISO DNGA150412 dimensions; compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness — matched holders, clamps and screws ensure repeatable seating.

What does the BX360 designation mean?
BX360 denotes the CBN grade used on the insert; it characterises the abrasive composition and wear behaviour optimised for hard turning applications and abrasive, wear‑intensive finishing.

Can the insert be used for internal turning as well as external turning?
Yes. The insert is specified for both external and internal turning within the limits of the holder geometry and the required cutting conditions for hardened materials.
