Boneham SF205DO Slip-fixed Drill Bushing 0.113 in Id Steel

Product Description

The BONEHAM SF205DO is a slip-fixed drill bushing designed to guide cutting tools with precise, repeatable accuracy in jig and fixture applications. It carries an industry designation of SF and features a 0.113 inch inside diameter (wire size No. 33), a 5/16 inch body outside diameter, and a 5/16 inch length under head. The body is machined from steel and hardened to 60 to 65 HRC, delivering the wear resistance required in production drilling environments. A head style design and renewable construction allow the bushing to be replaced without disturbing the jig plate. Lock screw compatibility is rated for LS-1 hardware.

Slip-fixed bushings in the SF series are used in drill jigs, fixture plates, and tooling setups where a headed, renewable bushing must be held firmly during the cutting operation. This bushing is appropriate for light-to-medium production work where consistent hole location is critical. It is installed and serviced by toolmakers, machinists, and fixture builders working to ANSI standards. The head outside diameter measures 35/64 inch and head height is 1/4 inch, allowing it to seat flush against standard jig plate counterbores when applicable.

Key Features

• SF industry code slip-fixed design holds the bushing in place during drilling operations
• 0.113 inch ID with an inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life in production environments
• Renewable bushing design allows replacement without reworking the jig plate
• LS-1 compatible lock screw interface for secure retention
• Conforms to ANSI standards for drill bushing geometry and tolerancing

Compatibility

Designed as an ANSI-standard SF-series slip-fixed drill bushing compatible with jig plates and fixtures that accept a 5/16 inch body outside diameter renewable bushing and use LS-1 lock screws.

Installation Notes

Installation is performed by toolmakers or machinists working with drill jig assemblies. Ensure the liner bushing or jig plate bore is clean and dimensionally correct before pressing or inserting the bushing. Secure the bushing using an LS-1 compatible lock screw tightened per shop practice. Always verify tool clearance and bushing alignment before beginning production drilling operations.
