Boneham CB00001300 Slip-fixed Drill Bushing 0.157 in Id

Product Description

The BONEHAM CB00001300 is a slip-fixed drill bushing designed for precision hole-location and tooling applications in metalworking and machining operations. Classified under bushing industry code SF, it features a 0.157 inch inside diameter (equivalent to a number 22 wire gauge bore) with a close inside diameter tolerance of plus 0.0001 to plus 0.0004 inches. The body outside diameter measures 0.5 inches with a length under head of 0.75 inches. Constructed from hardened steel at 60 to 65 HRC, this renewable bushing provides repeatable accuracy in drill jig and fixture setups. Installation is handled by machinists, toolmakers, and fixture builders working to ANSI standards.

This bushing is used in drill jig fixtures where guided drilling, reaming, or boring operations require consistent hole location across production runs. The slip-fixed design allows the bushing to be installed into a liner bushing and secured in place, making it suited for applications where tooling must remain stationary during the cutting operation. Compatible with an LS-1 lock screw for positive retention. The head type construction seats against the jig plate surface for controlled depth positioning.

Key Features

• Slip-fixed SF bushing classification per ANSI standards for standardized fixture compatibility
• Inside diameter of 0.157 inches (number 22 wire gauge) with tight tolerance of plus 0.0001 to plus 0.0004 inches
• Hardened steel construction at 60 to 65 HRC for wear resistance in high-cycle drill jig use
• Head type design with 51/64 inch head outside diameter and 0.25 inch head height for positive seating
• Renewable bushing construction allows replacement without disturbing the liner bushing or jig plate
• LS-1 lock screw compatible for secure retention during drilling operations

Compatibility

Designed for use with LS-1 compatible lock screws in standard ANSI drill jig fixture setups using liner bushings sized for a 0.5 inch body outside diameter slip-fixed bushing.

Installation Notes

Installation is performed by toolmakers or machinist-level personnel working on drill jig fixtures. The bushing is pressed or slipped into a mating liner bushing already installed in the jig plate, then secured with an LS-1 lock screw. Ensure the mating liner bushing bore and the jig plate surfaces are clean and free of burrs before installation. Follow ANSI B94.33 or applicable shop standards for drill bushing installation procedures.
