Boneham SF4816LK Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM SF4816LK is a slip-fixed drill bushing designed for use in jig and fixture applications requiring precise hole location and repeatable accuracy. Built to ANSI standards, this SF-series bushing features a 0.5 inch inside diameter, a 0.75 inch body outside diameter, and a 1 inch length under head. Constructed from hardened steel with a Rockwell hardness of 60 to 65 HRC, it delivers the wear resistance required for high-cycle drilling operations. The headed design allows controlled seating in the jig plate, and the bushing is renewable, making it suitable for production environments where tooling components must be replaced without scrapping the fixture body.

This bushing is used in jig and fixture tooling across metalworking, machining, and manufacturing environments. It installs into a slip-fixed liner bushing pressed into the jig plate, allowing the SF bushing to be rotated and removed for tool changes without disturbing the liner. Typical applications include production drilling, reaming, and boring operations where consistent hole placement is critical. The LS-1 compatible lock screw secures the bushing in position during operation, preventing rotation or axial movement under cutting forces.

Key Features

• Slip-fixed (SF) bushing design allows removal and replacement without disturbing the liner bushing
• Hardened steel construction rated 60 to 65 HRC for extended wear life in production drilling
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for precise drill guidance
• Headed design provides positive seating and controlled depth in the jig plate
• Renewable bushing construction supports high-volume fixture maintenance
• LS-1 compatible lock screw interface for secure retention during operation

Compatibility

Compatible with LS-1 series lock screws. Designed as an OEM-style slip-fixed replacement bushing for use with standard ANSI SF-series liner bushings in jig and fixture tooling.

Installation Notes

Installation is typically performed by a machinist or tooling technician. Ensure the mating liner bushing bore is clean and free of chips or burrs before inserting the SF bushing. Secure with an LS-1 compatible lock screw to prevent rotation during drilling. Always verify inside diameter tolerance and head seating before running production parts.
