FM-DBR7-SC-ADJ KATO Deburring Tool Holder – Adjustable Spring Load


The FM-DBR7-SC-ADJ KATO Deburring Holder is engineered for precision front-side deburring and chamfering in CNC machining centers and automated systems. Featuring an adjustable spring-load mechanism, the SC model maintains consistent cutting pressure, enabling smooth, repeatable deburring of holes and edges — even when dimensional variations are present in the workpiece.
Designed for high-reliability production environments, this holder absorbs minor Z-axis irregularities while maintaining stable contact with the part surface. When paired with a 90° cone-shaped carbide rotary burr, the FM-DBR7-SC-ADJ ensures optimal cutting force transmission and superior surface consistency across a wide range of materials.
As the exclusive North American distributor of KATO deburring systems, Bel Air Finishing provides manufacturers with complete tooling solutions that enhance quality, efficiency, and automation in deburring applications.
Key Features & Benefits
