Boneham SF6416NC Slip-fixed Drill Bushing 0.75 in Id

Product Description

The BONEHAM SF6416NC is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel and hardened to 60 to 65 HRC, this SF-series bushing delivers the wear resistance required for high-cycle drilling, reaming, and boring operations. The bushing features a 0.75 inch inside diameter, a 1 inch body outside diameter, and a 1 inch length under the head. It ships as a renewable bushing, meaning it installs into a press-fit liner and can be swapped out without disturbing the fixture plate. Lock screw compatibility with the LS-2 screw keeps the bushing indexed and secured during operation.

SF-series slip-fixed bushings are standard toolroom and production components used wherever a guided cutting tool must be located accurately and consistently. Typical applications include drill jigs, assembly fixtures, and multi-operation tooling setups in metal fabrication, aerospace, and general machining environments. The renewable design suits production lines where bushing replacement is a routine maintenance task. Toolmakers, machinists, and fixture builders are the primary installers. The headed design seats against the fixture plate surface, providing a positive stop during installation.

Key Features

• Slip-fixed (SF) bushing design seats in a press-fit liner and locks in place with an LS-2 compatible lock screw
• Steel construction hardened to 60 to 65 HRC for extended wear life in high-cycle tooling applications
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures precise tool guidance
• Renewable bushing construction allows field replacement without disturbing the liner or fixture plate
• Head outside diameter of 1.4375 inches (1-27/64 inches) and head height of 0.375 inches provide a stable seating surface
• Conforms to ANSI standards for drill bushing geometry and dimensional interchangeability

Compatibility

Designed for use with ANSI-standard slip-fixed liner bushings and LS-2 series lock screws. Dimensionally interchangeable with other ANSI SF-series drill bushings of the same ID, body OD, and length specification.

Installation Notes

Installation is typically performed by a toolmaker or machinist using standard hand tools and a press. The bushing slips into a pre-installed liner bushing and is secured with an LS-2 lock screw to prevent rotation or axial movement during use. Ensure the liner bore and bushing exterior are clean and free of chips or burrs before installation. Follow applicable shop safety procedures and fixture design standards when integrating bushings into jig plates.
