Boneham SF4816JW Slip-fixed Drill Bushing 0.386 in Id

Product Description

The BONEHAM SF4816JW is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and similar machining operations. Built to industry code SF, this bushing features a 0.386 inch inside diameter (Letter size W), a 0.750 inch body outside diameter, and a 1 inch length under head. Constructed from steel, it includes a head for positive seating and is renewable, allowing it to be replaced without disturbing the jig plate. Inside diameter tolerance is held to +0.0001 to +0.0005 inches for consistent tool guidance. Lock screw compatibility is LS-1.

This bushing is used in drill jig applications across metalworking, tooling, and manufacturing environments. The slip-fixed design allows the bushing to be installed and locked in a liner bushing, providing a stable, repeatable guide for production drilling operations. It is well suited for applications where tool changes are infrequent and a secure, non-rotating fit is required. Machinists, tool and die makers, and fixture builders working in job shops or production facilities are the primary installers.

Key Features

• Slip-fixed (SF) bushing style for secure, locked installation in liner bushings
• 0.386 inch inside diameter with tight tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• Steel construction for durability in production machining environments
• Renewable design allows replacement without disturbing the jig plate or liner
• Headed style provides positive axial location against the jig plate surface
• LS-1 compatible lock screw for secure retention during operation

Compatibility

Designed for use with LS-1 lock screws and compatible liner bushings accepting a 0.750 inch body outside diameter slip-fixed bushing per SF industry standards.

Installation Notes

Installation is typically performed by machinists or tooling specialists during jig assembly or bushing replacement. Ensure the liner bushing bore and jig plate surfaces are clean and free of burrs before inserting the slip-fixed bushing. Engage the LS-1 lock screw to prevent rotation or axial movement during cutting operations. Power down all associated machinery before servicing drill jigs or replacing worn bushings.
