Boneham CB00001173 Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM CB00001173 is a slip-fixed (SF) drill bushing designed for use in jig and fixture tooling applications. It features a 0.257 inch inside diameter, a 0.500 inch body outside diameter, and a 1 inch length under head. Machined from steel and hardened to 60 to 65 HRC, this bushing provides precise hole location guidance for drilling, reaming, and boring operations. It is a renewable bushing, meaning it is designed to be replaced in service after wear. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures consistent fit and accurate tool guidance over repeated production runs.

Slip-fixed bushings are used in drill jig assemblies where a bushing must be locked in position during the operation but can be removed and replaced without disturbing the jig body. This CB00001173 bushing is appropriate for light to medium production environments in metalworking, machining, and fabrication shops. It is compatible with a standard LS-1 lock screw for positive retention in the liner bushing. The head-style configuration with a 51/64 inch head outside diameter and 1/4 inch head height provides a positive stop against the jig plate surface during installation.

Key Features

• Slip-fixed (SF) bushing type per ANSI standards for renewable jig tooling applications
• Inside diameter of 0.257 inches (Letter F) with a tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for wear resistance and long service life
• Renewable design allows field replacement without jig rework
• Compatible with LS-1 lock screw for secure retention in the liner bushing
• Head-style body with 51/64 inch head OD and 1/4 inch head height for positive seating against the jig plate

Compatibility

Designed as an ANSI-standard slip-fixed renewable drill bushing compatible with LS-1 lock screws and standard liner bushings sized for a 0.500 inch body outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers setting up drill jigs and fixtures. The slip-fixed bushing seats into a pressed liner bushing and is secured with an LS-1 lock screw to prevent rotation during drilling. Ensure the jig assembly is de-energized and secured before replacing worn bushings. Follow applicable shop safety procedures and tooling manufacturer guidelines when handling hardened components.
