Boneham SP00005421 Slip-fixed Drill Bushing 17/64 in

Product Description

The BONEHAM SP00005421 is a slip-fixed drill bushing designed for precision hole-location and tooling applications in machining and fabrication environments. Built to industry code SF, it features a 17/64 inch inside diameter with a close tolerance of +0.0001 to +0.0005 inches, a 1/2 inch body outside diameter, and a 1-1/2 inch length under the head. Constructed from steel and hardened to 60 to 65 HRC, this bushing delivers consistent bore alignment and wear resistance under repeated drill and reamer passes. It is a renewable bushing, meaning it can be removed and replaced without disturbing the liner. Installation uses the LS-1 compatible lock screw. Machinists, tool and die makers, and fixture builders typically specify this component for jig plate assemblies.

This slip-fixed bushing is suited for use in drill jig fixtures where repeatable part location is critical. The SF configuration allows the bushing to be locked in position once seated in a liner bushing pressed into the jig plate, making it appropriate for production runs where the same drill or reamer is used across multiple workpieces. The head provides a positive stop against the jig plate surface. Applications span general metalworking shops, aerospace component fixturing, and precision machining operations requiring ANSI-compliant tooling components.

Key Features

• Slip-fixed SF configuration locks into a liner bushing for production-run stability
• 17/64 inch inside diameter with +0.0001 to +0.0005 inch tolerance for accurate tool guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Renewable design allows bushing replacement without liner removal
• LS-1 compatible lock screw interface for secure retention
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as an ANSI-compliant slip-fixed replacement bushing for use with standard SF-series liner bushings. Compatible with LS-1 lock screws.

Installation Notes

Installation is performed by machinists or tool and die professionals working with drill jig fixtures. The bushing slips into a pressed liner bushing already seated in the jig plate and is secured with an LS-1 lock screw. Ensure the work holding fixture is fully secured and the machine spindle is powered down before servicing or replacing bushings. Do not force the bushing into an undersized liner, as this can damage the bore tolerance.
