Product Overview
Composite Brazed CBN Inserts for Precision Finishing
UHD composite brazed CBN inserts combine a carbide substrate with a brazed CBN composite layer. Designed primarily for small-allowance finishing of hardened steel, they help precision manufacturers address tool marks, dimensional variation and tool-change demands on CNC lathes and automated lines. Grade-specific options are also available for other listed materials and cutting conditions.
