Boneham CB00001143 Slip-fixed Drill Bushing 9/32 in

Product Description

The BONEHAM CB00001143 is a slip-fixed (SF) drill bushing used to guide cutting tools with precision during drilling, reaming, and boring operations. Manufactured from steel, it features a 9/32 inch inside diameter and a 1/2 inch body outside diameter, with a 1 inch length under the head. The headed design seats flush against the jig plate and resists axial pullout during tool engagement. This bushing is designed to be renewable, allowing it to be removed and replaced without reworking the jig plate. Inside diameter tolerance is held to +0.0001 to +0.0005 inches for consistent tool guidance across production runs.

Slip-fixed bushings of this type are used in drill jigs and fixture assemblies across machining, metalworking, and fabrication environments. The SF designation indicates the bushing slips into the liner bushing and is then locked in place during the drilling operation. This part is suitable for production tooling where accurate hole placement and repeatable tool guidance are required. It is compatible with LS-1 lock screws, which secure the bushing in the liner during use. Installation is performed by tooling technicians and fixture builders in machine shop and manufacturing settings.

Installation Notes

Installation is performed by tooling technicians or fixture builders. Ensure the jig plate and liner bushing are clean and free of chips or burrs before pressing the bushing into position. Secure with an LS-1 lock screw before beginning the drilling cycle. Power down and lock out all machine tools before servicing or replacing bushings in an active fixture.
