Boneham CB00001229 Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM CB00001229 is a slip-fixed (SF) drill bushing designed to guide cutting tools with precision in jig and fixture applications. Machined from steel and hardened to 60 to 65 HRC, this bushing features an inside diameter of 0.196 inches (wire size No. 9) with a close tolerance of +0.0001 to +0.0004 inches to maintain accurate hole location across repeated operations. The body outside diameter measures 0.500 inches with a length under head of 1 inch. The head outside diameter is 51/64 inch and the head height is 1/4 inch. It is compatible with the LS-1 lock screw for positive retention in the liner bushing. Installation is performed by machinists and tooling technicians in production environments.

This slip-fixed bushing is suited for use in drill jigs and machining fixtures where the bushing must be locked in place during the drilling operation but can be removed for replacement or changeover. The renewable design allows the bushing to be swapped out when worn without replacing the entire jig assembly. Typical applications include production drilling, reaming, and boring operations in metal fabrication and precision machining shops. The SF industry code designates it for use in conjunction with a liner bushing and lock screw assembly per ANSI standards.

Compatibility

Designed for use with ANSI-standard liner bushings and the LS-1 lock screw. Suitable as a renewable slip-fixed drill bushing in production jigs and fixtures requiring a No. 9 (0.196 inch) bore.

Installation Notes

Installation is performed by qualified machinists or tooling personnel. Ensure the liner bushing is clean and free of chips or burrs before inserting the slip-fixed bushing. Lock the bushing in place using the compatible LS-1 lock screw before beginning any drilling or reaming operation. Always de-energize and lock out machinery before servicing jig components.
