Boneham SF8822NE Slip-fixed Drill Bushing 49/64 in Id

Product Description

The BONEHAM SF8822NE is a slip-fixed drill bushing designed for precision hole location in jig and fixture applications. It carries an industry classification of SF and features a 49/64-inch inside diameter with a 1.375-inch body outside diameter. The head outside diameter measures 1-51/64 inches and the head height is 3/8 inch, with a length under the head of 1-3/8 inches. Constructed from steel, this bushing is renewable and compatible with an LS-2 lock screw. It is installed and removed without tools by slipping it into a liner bushing, making it well suited for production drilling operations where bushings are changed frequently.

This slip-fixed bushing is used in drill jigs for production and toolroom machining environments. The SF designation identifies it within the industry-standard bushing classification system, making it a recognized fit for jig plates and fixture assemblies that require repeatable, accurate drill guidance. It is appropriate for metalworking shops, tooling departments, and precision machining operations where renewable bushing setups are standard practice. A licensed machinist or toolmaker typically handles installation in these settings.

Compatibility

Designed for use with LS-2 compatible lock screws and standard liner bushings that accept SF-series slip-fixed drill bushings per industry classification conventions.

Installation Notes

A toolmaker or machinist installs this bushing by slipping it into a properly sized liner bushing already pressed into the jig plate and securing it with an LS-2 lock screw. Ensure the liner bushing bore and the jig plate are clean and free of chips before seating the bushing. Do not hammer or force the bushing into the liner; slip-fixed bushings are designed for tool-free hand insertion. Always verify inside diameter clearance against the drill or reamer shank before use.
