Boneham SP00005845 Slip-fixed Drill Bushing 9/16 in Id

Product Description

The BONEHAM SP00005845 is a slip-fixed (SF) drill bushing designed to guide cutting tools with precision in jig and fixture applications. Machined from steel and hardened to 60 to 65 HRC, it provides consistent bore alignment and long service life in high-repetition drilling operations. The bushing features a 9/16 inch inside diameter, a 3/4 inch body outside diameter, and a 3/8 inch length under the head. It accepts an LS-1 compatible lock screw to secure the bushing in the liner. Typical installers are tool-and-die makers, machinists, and fixture builders working in production machining environments.

This bushing is suited for fixed-station drill jig setups where the bushing remains installed in the liner throughout the production run. The slip-fixed design locks into a head-type liner using an LS-1 lock screw, preventing rotation or axial movement under drilling forces. It is appropriate for both light and moderate production volumes in metalworking shops, job shops, and manufacturing facilities requiring repeatable hole location accuracy.

Key Features

• Slip-fixed (SF) installation method locks into liner with LS-1 compatible lock screw
• Steel construction hardened to 60 to 65 HRC for wear resistance and dimensional stability
• 9/16 inch inside diameter with a close tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• 3/8 inch length under head suits standard jig plate thicknesses
• Renewable bushing design allows replacement without disturbing the liner or jig plate
• Meets ANSI standards for drill bushing geometry and interchangeability

Compatibility

Designed as an ANSI-standard slip-fixed drill bushing compatible with head-type liner bushings and LS-1 lock screws. Fits standard SF-series jig bushing liners sized for a 3/4 inch body outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using standard bushing press or hand-press methods. Ensure the liner is clean and free of chips or burrs before inserting the bushing. Secure with an LS-1 lock screw torqued to fixture builder specifications. Always verify inside diameter clearance against the drill or reamer being guided before placing the jig in service.
