Boneham SF208FP Slip-fixed Drill Bushing 0.182 in Id Steel

Product Description

The BONEHAM SF208FP is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Built to the SF industry code and conforming to ANSI standards, this bushing features a 0.182 inch inside diameter sized for a No. 14 wire gauge drill, a 5/16 inch body outside diameter, and a 0.5 inch length under head. Manufactured from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for production jig work. The headed design and LS-1 lock screw compatibility allow secure seating in a liner bushing without rotation during tool operation.

This bushing is used in drill jigs and fixture plates across metalworking, machining, and tooling applications. It is appropriate for both job shop and production-floor environments where repeatable hole location accuracy is critical. The renewable design allows the bushing to be replaced individually without disturbing the jig body, making it well-suited for high-cycle tooling setups in manufacturing and fabrication operations.

Key Features

• SF-series slip-fixed design with headed configuration for secure lock screw retention
• 0.182 inch inside diameter (No. 14 wire size) with a tight tolerance of +0.0001 to +0.0004 inches
• 5/16 inch body outside diameter and 0.5 inch length under head for standard jig plate fitment
• Steel construction hardened to 60 to 65 HRC for extended tool wear life
• Compatible with LS-1 lock screw for positive rotational locking
• Renewable bushing — individually replaceable without jig body rework
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed for use with LS-1 compatible lock screws and standard liner bushings conforming to ANSI SF-series drill bushing specifications. Fits jig plates and fixture bodies machined to accept a 5/16 inch body outside diameter bushing.

Installation Notes

Installation is typically performed by toolmakers or machining technicians using appropriate press-fit or hand-press equipment. Ensure the receiving liner bushing bore and the jig plate surfaces are clean and free of burrs before seating the bushing. Secure with an LS-1 lock screw to prevent rotation during drilling operations. Follow applicable shop safety procedures and power down any associated machine tools before servicing or replacing bushings in an active fixture.
