Boneham CB00001142 Slip-fixed Drill Bushing 17/64 in

Product Description

The BONEHAM CB00001142 is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built from steel, this bushing features a 17/64 inch inside diameter, a body outside diameter of 0.5 inches, and a length under the head of 1 inch. The inside diameter tolerance is held to a tight +0.0001 to +0.0005 inches, ensuring consistent tool guidance and repeatable hole location. It includes a head and is compatible with the LS-1 lock screw for positive retention in the liner bushing. Machinists, tool and die makers, and production shops rely on this style of bushing for high-volume drilling, reaming, and boring operations.

This slip-fixed bushing is intended for use in drill jigs where the bushing must be removable and locked in place during operation. The SF designation follows standard industry bushing codes, making it straightforward to cross-reference with jig plate designs and fixture drawings. It is well suited for metalworking environments where precision hole location is critical across repeated setups. The renewable design allows the bushing to be replaced as it wears without modifying the jig plate, reducing fixture maintenance downtime.
