Boneham SF3222GX Slip-fixed Drill Bushing 15/64 in Id

Product Description

The BONEHAM SF3222GX is a slip-fixed drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations in jig and fixture applications. It features a 15/64-inch inside diameter and a 1/2-inch body outside diameter, with a head-type configuration that seats against the jig plate surface. The bushing is machined from steel and includes a counterbored head with a head outside diameter of 51/64 inch and a head height of 1/4 inch. The inside diameter tolerance is held to a tight +0.0001 to +0.0004 inch range, ensuring consistent tool guidance and repeatable hole location across production runs.

This bushing is intended for use in drill jigs and precision fixturing in metalworking and manufacturing environments. The slip-fixed style allows the bushing to be inserted and locked in place within a jig liner using an LS-1 compatible lock screw, making it suitable for fixed-station drilling setups where the same tool is used throughout a production cycle. Renewable bushing construction means the SF3222GX can be replaced independently without disturbing the jig liner, reducing maintenance downtime in shop environments.

Key Features

• 15/64-inch inside diameter with tight tolerance of +0.0001 to +0.0004 inch for precise tool guidance
• 1/2-inch body outside diameter and 1-3/8-inch length under head for secure jig plate seating
• Head-type design with 51/64-inch head OD and 1/4-inch head height
• Counterbored head accommodates LS-1 compatible lock screw for positive retention
• Renewable bushing construction allows field replacement without liner removal
• Steel construction for durability under repeated drilling operations

Compatibility

Designed for use with LS-1 compatible lock screws and standard jig liner systems following SF industry bushing standards. Fits jig plates and fixtures dimensioned for a 1/2-inch body outside diameter slip-fixed bushing.

Installation Notes

Installation is performed by machinists or tooling technicians. Ensure the jig liner bore is clean and free of chips or burrs before inserting the bushing. Secure the SF3222GX using an LS-1 compatible lock screw tightened to the fixture manufacturer specifications. Do not force the bushing into an undersized liner bore, as this can distort the inside diameter and compromise tool guidance accuracy.
