CPGA 090208 BX360 CPGA090208-QBN — Tungaloy ISO turning insert for turning, CBN for hardened steels, 80°

the CPGA090208-QBN BX360 is an ISO‑standard rhombic turning insert designed for finishing and hard turning applications where wear resistance and edge stability are essential

• CBN grade BX360 for hardened steel machining
• Rhombic 80° geometry for versatile turning
• 11° clearance angle for secure cutting action
• Cylindrical hole for reliable mounting

Increase uptime with a wear‑resistant CBN solution

The BX360 grade uses cubic boron nitride (CBN) to deliver superior abrasion resistance in hard finishing operations. This results in longer tool life and more consistent component tolerances, reducing the frequency of insert changes and machine downtime. For production environments working with high‑hardness steels, the switch to a CBN finishing insert provides measurable gains in process stability and surface quality without complex requalification of the machining cell.

Fast, reliable fitting for proven productivity gains

As an ISO turning insert, compatibility with holders depends on form, clearance angle, tolerance class, fixing method, size and thickness. The rhombic shape with an 80° included angle, 11° clearance, and a 0.8 mm corner radius enables straightforward mounting in standard external holders or boring bars. The insert's cylindrical hole ensures repeatable clamping; combined with the standardised dimensions, this reduces setup time and simplifies tool inventory management, supporting leaner workshop logistics.

Optimised for hardened steels and demanding finish passes

The cutting material and chipbreaker selection make this insert particularly suitable for hardened steel finishing and—depending on the variant—certain cast iron operations. The CBN cutting edge maintains a sharp profile under high abrasion, producing finer surface finishes and stable dimensional results. Select the QBN chipbreaker and the appropriate grade variant to match workpiece hardness, cutting direction and machine rigidity to achieve the best balance between life and surface integrity.

Practical system advice for consistent results

An efficient cutting system consists of the ISO insert, a matching external holder or boring bar, a correct underlay/clamp set and spare fixing screws. Given the insert's 2.38 mm thickness and ISO size 09, choose a holder with matching pocket clearance to preserve tolerance and edge support. For process optimisation, combine the grade's strengths with stable clamping and conservative approach parameters when first introducing CBN into a cycle; once proven, the grade typically supports increased cutting speeds and fewer interventions.

FAQ

What materials is this insert designed for?
The CPGA090208‑QBN BX360 insert is engineered primarily for hardened steels, with certain BX360 variants also suitable for specified cast iron applications.

How does the CBN cutting material benefit finishing operations?
CBN in the BX360 grade gives high abrasion resistance and edge stability, allowing the insert to maintain surface quality and dimensional accuracy over longer production runs.

Which holder features are required for correct fitting?
A standard ISO external holder or boring bar with matching pocket geometry, correct clamp/underlay set and screw fixation is required to secure the CPGA insert and ensure repeatable performance.

Is the corner radius suitable for fine finishing?
The 0.8 mm corner radius provides a compromise between edge strength and achievable surface finish, making it suitable for many finishing passes on hardened components.

Can this insert reduce overall machining time?
By offering extended edge life and consistent cutting behaviour, the BX360 CBN insert can reduce tool changes and improve process stability, contributing to reduced overall machining interruptions.
