Kyocera TBZ01456 Cbn Turning Insert CNGA431S00525ME KBN25M

Product Description

The KYOCERA TBZ01456 is a cubic boron nitride (CBN) turning insert in the CNGA431S00525ME geometry, finished with KYOCERA MEGACOAT PVD coating and graded KBN25M. It features an 80-degree diamond insert shape, a 1/2-inch inscribed circle, and a 1/64-inch corner radius. With a neutral hand orientation and a honed cutting edge, it is engineered for high-precision material removal on hard workpiece materials. The multi-tipped design provides two cutting edges per insert, making it a practical choice for shops running tight-tolerance finishing operations. Licensed machinists and CNC turning specialists are the primary installers and users of this tooling.

This insert is suited for hard turning applications including external turning, boring, internal facing, chamfering, and facing operations. It is designed for use on hard materials designated under ISO workpiece material code H, such as hardened steels and hard cast irons. The ISOI series designation aligns with both ANSI and ISO tooling standards, making it compatible with standard CNGA-style toolholders used across CNC lathes and turning centers in both production and job-shop environments.

Compatibility

Designed for use in standard CNGA-style toolholders compatible with the ISOI series. Suitable for CNC lathes and turning centers running hard turning operations. ISO code reference: CNGA120404S01225ME. Industry standard number: CNGA431S00525MEKBN25M.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. The machine spindle must be stopped and the turret fully indexed and locked before seating or replacing inserts. Secure the insert using the clamp and pin holding method specified for the toolholder; do not overtighten the clamp screw beyond the toolholder manufacturer specification. Inspect the cutting edge and seating pocket for debris before clamping to ensure proper insert contact and runout control.
