Boneham SF325FF Slip-fixed Drill Bushing 0.1695 in Id

Product Description

The BONEHAM SF325FF is a slip-fixed drill bushing designed for precision tooling and jig applications in metal fabrication and machining. It features an inside diameter of 0.1695 inches, corresponding to a Number 18 wire gauge drill size, with an inside diameter tolerance of positive 0.0001 to positive 0.0004 inches for accurate hole location. The body outside diameter measures 0.5000 inches with a length under head of 5/16 inches. Constructed from steel, this bushing includes a head and is compatible with the LS-1 lock screw, making it a renewable bushing suitable for repeated removal and replacement in jig plates. Machinists and toolmakers install this component in drill jig setups requiring repeatable accuracy.

The SF325FF fits standard slip-fixed bushing applications where the bushing must be inserted and locked in position during a drilling operation. The SF industry code designates its slip-fixed configuration, which allows the bushing to be removed and swapped without disturbing the jig liner. This type is commonly used in production drilling jigs across manufacturing, maintenance, and repair environments where multiple drill sizes or operations are required at a single hole location.

Key Features

• Slip-fixed SF-type bushing for use with renewable jig liner systems
• 0.1695 inch inside diameter corresponding to Number 18 drill size
• Inside diameter tolerance of positive 0.0001 to positive 0.0004 inches for precision location
• Steel construction for durability in repeated drilling cycles
• Compatible with LS-1 lock screw for secure seating during operation
• Renewable design allows removal and replacement without jig plate rework

Compatibility

Designed as an SF-industry-code slip-fixed renewable drill bushing compatible with LS-1 lock screws and standard jig liner systems accepting a 1/2 inch body outside diameter bushing.

Installation Notes

Installation is performed by toolmakers or machinists during jig setup or bushing replacement. The jig plate and any associated fixturing should be secured and clear of power before inserting or removing the bushing. The LS-1 lock screw must be properly engaged to prevent rotation or lift-out during drilling. Follow applicable shop standards and tooling drawings for correct seating depth and orientation.
