DNGA 150408 BX360 Tungaloy turning insert — 55° rhombic, CBN grade

DNGA 150408 BX360 is an ISO-format turning insert designed for high-hardness finishing and wear-intensive machining.

• BX360 CBN for hardened steels
• Rhombic DNGA 55° geometry
• 0° relief angle for stable cutting
• 0.8 mm corner radius for accurate finish
• Cylindrical hole, 15 mm size, 4.76 mm thick

Precision finishing for hardened components

The BX360 grade uses cubic boron nitride (CBN) as the cutting material, offering superior hardness and thermal stability compared with conventional abrasives; this makes it particularly suitable for hardened steels and certain cast irons in end-machining operations. The medium-sized 0.8 mm corner radius promotes an even cutting edge for improved surface quality while balancing edge strength, which helps to reduce chatter and extend the effective cutting life in finishing passes. The result is a predictable, repeatable profile where dimensional conformity is critical.

Reliable interface and secure clamping for stable machining

Compatibility is determined by shape, relief angle, tolerance class, fastening, size and thickness, so the ISO designation ensures consistent fit with appropriately matched holders. The rhombic 55° geometry provides an advantageous approach angle for external and internal turning, and the 0° relief contributes to neutral rake characteristics for stable cutting forces. When paired with a suitable external holder or boring bar plus the correct shim and clamping set, the system reduces vibration and supports predictable tool life.

Practical system components and reduced downtime

The system comprises the ISO turning insert, a mating external holder or boring bar, an underlay/clamp set and replacement screws; spare parts and correct torque settings are essential for safe operation. The insert’s cylindrical hole eases positive locating and secure fastening in many standard clamping systems, facilitating indexable changes and keeping setup times low. For production environments the combination of straightforward indexing and the BX360 wear properties translates to fewer interruptions and improved overall throughput.

Application guidance and material matching

While the insert excels in finishing hardened steels, selection of chipbreaker style and matching insert grade should reflect the workpiece, machining strategy and machine stability. This particular ISO-format rhombic insert is supplied without a chipbreaker, allowing selection of a geometry that suits the feed and depth of cut for fine finishing or semi-finishing. For high-volume or difficult-to-machine alloys, pairing the right holder rigidity and conservative cutting parameters at first run will confirm suitability before ramping production.

FAQ

What materials is this insert designed for?
The DNGA 150408 BX360 Tungaloy turning insert is designed primarily for hardened steels and, depending on specific BX360 variants, certain cast irons; it is optimised for wear-intensive finishing.

How does the 0° relief angle affect machining?
A 0° relief angle on this ISO-format insert produces a neutral geometry that helps maintain stable cutting forces and supports predictable tool life under finishing conditions for the DNGA 150408 BX360 insert.

Which toolholders fit this insert?
Holders compatible with the DNGA family and the ISO size 150408 will accept the insert; compatibility depends on matching the rhombic shape, 55° approach angle, thickness and cylindrical locating hole.

Is this insert supplied with a chipbreaker?
This version of the insert is supplied without a chipbreaker, allowing the selection of a specialised chip-control geometry where required for the specific material and cutting parameters.

How should the corner radius be used for finishing passes?
The 0.8 mm corner radius on the DNGA 150408 BX360 offers a balance between a fine surface finish and sufficient edge strength; it is well suited to finishing feeds where surface integrity and form accuracy are priorities.
