The JACOBS 30609 is a replacement drill chuck hood designed for use with the Keyless Precision Drill Chuck. The hood serves as the outer protective shell of the chuck assembly, maintaining structural integrity and protecting internal chuck components during operation. It is a direct OEM-style replacement part intended for technicians and machinists who need to restore a worn or damaged chuck to factory condition. Installation requires basic mechanical familiarity with drill chuck disassembly and reassembly procedures.
This hood is compatible with Chuck No. 80 and fits Keyless Precision Drill Chuck assemblies where that chuck number applies. It is appropriate for use in machine shop, manufacturing, or industrial maintenance environments where JACOBS keyless chucks are in service. Facilities maintaining drill presses, CNC machines, or handheld power tools equipped with compatible JACOBS chuck assemblies will find this a direct-fit replacement component.
Compatible with JACOBS Chuck No. 80 Keyless Precision Drill Chuck assemblies (Model H-80).
