Boneham SF4816IF Slip-fixed Drill Bushing 19/64 Id 3/4 Od

Product Description

The BONEHAM SF4816IF is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features a 19/64 inch inside diameter, a 3/4 inch body outside diameter, and a 1 inch length under head. The bushing is machined from steel for durability under repeated tooling cycles. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures close, consistent tool guidance. A renewable design allows the bushing to be replaced without disturbing the liner bushing already installed in the jig plate. This part is installed by machinists, tool-and-die makers, and manufacturing maintenance technicians in production tooling environments.

The SF4816IF is used in drill jigs and fixture plates where slip-fixed bushing style installation is required. The SF industry code designates a headed, slip-fit bushing that locks in place via a lock screw rather than a press fit. This makes it well suited for applications where the bushing must be rotated or exchanged during a multi-operation drilling sequence. The head type construction and 1-3/64 inch head outside diameter provide positive seating against the jig plate face. Lock screw compatibility with the LS-1 screw retains the bushing during operation.

Key Features

• Slip-fixed installation method for quick removal and replacement in liner bushings
• Steel construction for wear resistance in repetitive drilling applications
• Inside diameter tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• Headed design with 1-3/64 inch head OD and 1/4 inch head height seats flush against jig plate
• Compatible with LS-1 lock screw for positive retention during machining
• Renewable bushing design allows field replacement without press-out of a permanent liner

Compatibility

Designed for use with LS-1 compatible lock screws in standard drill jig liner bushings conforming to SF industry bushing specifications.

Installation Notes

Installation is performed by machinists or fixture technicians. The slip-fixed bushing is inserted into a pre-installed liner bushing and locked in position using an LS-1 style lock screw. Ensure the jig plate and liner bushing bore are clean and free of chips before seating the bushing. Always disengage and secure the machine before inserting or removing drill bushings from a fixture plate.
