Kyocera TBZ05472 Cbn Turning Insert 35 Degree Diamond

Product Description

The KYOCERA TBZ05472 is a cubic boron nitride (CBN) turning insert designed for high-speed machining of hard and difficult-to-cut materials. It carries the industry standard designation VBGW221T00315ME and uses the KBN25M manufacturer grade with a MEGACOAT PVD coating applied to a micrograin CBN substrate. The insert features a 35-degree diamond shape with a neutral hand orientation, a 0.25 inch inscribed circle, a 1/64 inch (0.0156 inch) corner radius, and a 5-degree relief angle. With two cutting edges and a honed edge style, it delivers consistent performance in precision turning operations. Licensed machinists and CNC operators working in job shops, production facilities, or aerospace and automotive environments are the primary users.

This insert is suited for external turning, facing, profiling, copying, internal facing, back boring, and undercutting operations on hard materials. The primary workpiece material classification is H, covering hardened steels, hard cast irons, and similar hard-turning applications where CBN tooling is the standard choice over carbide. The ISOI series designation and compliance with both ANSI and ISO standards make it compatible with standard VBGW-style toolholders used across a wide range of CNC lathes and turning centers. It is sold individually and is suitable for multi-use applications across a range of part geometries.

Key Features

• Cubic boron nitride (CBN) insert material with micrograin substrate for hard-material turning
• KBN25M grade with MEGACOAT PVD coating for extended tool life on hardened workpieces
• 35-degree diamond insert shape (V) with 5-degree relief angle and positive rake geometry
• Honed cutting edge for consistent performance and reduced edge chipping on hard materials
• Two cutting edges per insert with neutral hand orientation for flexible setup
• Screw-type insert holding method; compatible with standard VBGW toolholders per ANSI and ISO
• Multi-use application coverage: external turning, facing, profiling, back boring, undercutting, and copying

Compatibility

Designed for use in standard VBGW-style screw-lock toolholders conforming to ANSI and ISO insert seating specifications. The ISO designation for this insert is VBGW110304T00815ME. Suitable for CNC lathes and turning centers configured for hard-material turning with CBN inserts.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the turret is locked out before seating or replacing the insert. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturers specified procedure without over-torquing the insert pocket. Inspect the toolholder pocket and seating surfaces for chips or debris before installing a new insert, as contamination in the pocket can cause premature edge failure or dimensional error.
