Boneham CB00001231 Slip-fixed Drill Bushing 0.191 in Id

Product Description

The BONEHAM CB00001231 is a slip-fixed drill bushing designed for precision hole-guidance applications in jig and fixture work. Built to industry code SF, it features an inside diameter of 0.191 inches (wire size 11) with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate drill alignment and repeatable hole positioning. The body outside diameter measures 0.500 inches with a length under head of 1 inch. Constructed from steel, this bushing is renewable and compatible with LS-1 lock screws for secure retention in the liner bushing. Machinists, toolmakers, and fixture builders install this type of component in production drilling setups.

Slip-fixed bushings of this type are used in drilling jigs where the bushing must be locked in place during the operation and removable for tool changes or bushing replacement. The SF style is a standard designation in jig bushing practice, making this part a direct fit for applications requiring a headed, renewable bushing seated in a liner. Typical installations occur in metalworking shops, manufacturing cells, and machine maintenance environments where hole-location accuracy is critical across repeated production runs.

Key Features

• Inside diameter of 0.191 inches (wire size 11) with tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Body outside diameter of 0.500 inches and 1 inch length under head for standard liner bushing fitment
• Steel construction provides wear resistance in high-cycle drilling applications
• Renewable design allows bushing replacement without disturbing the liner or jig plate
• Head outside diameter of 51/64 inches and head height of 1/4 inch for positive seating and retention
• LS-1 lock screw compatible for secure, slip-fixed installation in SF-style liner bushings

Compatibility

Designed as an OEM-style replacement or direct-fit component for SF-designation slip-fixed drill bushing applications using LS-1 compatible lock screws in standard jig bushing liners.

Installation Notes

Installation is typically performed by machinists or toolmakers using standard jig bushing press and lock screw tooling. Ensure the liner bushing bore and mating surfaces are clean and free of chips or burrs before seating the bushing. The LS-1 lock screw must be tightened to secure the bushing during drilling and loosened before removal. Follow applicable shop safety procedures and de-energize any associated machinery before servicing jig fixtures.
