Boneham CB00000374 Slip-fixed Drill Bushing 0.073 in Id

Product Description

The BONEHAM CB00000374 is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Classified under industry code SF, this bushing features a 0.073 inch inside diameter (wire size No. 49) and a 5/16 inch body outside diameter, with a length under head of 1/2 inch. Constructed from steel, it delivers the hardness and wear resistance required for repetitive production drilling. The headed design keeps the bushing positively seated in the jig plate, and the renewable construction allows it to be removed and replaced without retooling the fixture. Compatible with the LS-1 lock screw, it locks securely in a slip-fixed liner bushing.

This bushing is used in drill jig fixtures across metalworking, machining, and fabrication environments. It is suited for production environments where the same hole location must be drilled repeatedly with consistent accuracy. Machinists and toolmakers install this component into jig plates when guiding small-diameter drills or reamers. The renewable design makes it a practical choice for fixtures that require periodic bushing changes due to tool wear or changeover between operations. It is appropriate for light- to medium-duty machining applications where hole location tolerances are critical.

Key Features

• Slip-fixed (SF) industry classification for use in slip-fixed liner bushings with lock screw retention
• 0.073 inch inside diameter (No. 49 wire size) with inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction for hardness and wear resistance in production drilling operations
• Headed design with 35/64 inch head outside diameter and 1/4 inch head height for positive seating in jig plate
• Renewable bushing construction allows removal and replacement without modifying the fixture
• LS-1 lock screw compatible for secure retention during drilling operations

Compatibility

Designed for use with LS-1 compatible lock screws. Fits slip-fixed liner bushings conforming to SF industry standards. Verify liner bushing body bore and head counterbore dimensions before installation.

Installation Notes

Installation is typically performed by a machinist or toolmaker using standard jig-building practice. Ensure the liner bushing is fully seated and the jig plate counterbore is clean and free of chips before inserting this bushing. Engage the LS-1 lock screw to secure the bushing and prevent rotation or pullout during the drilling cycle. Always verify bushing inside diameter clearance against the intended drill or reamer shank before use.
