Boneham SF8822MZ Slip-fixed Drill Bushing 47/64 in Id Steel

Product Description

The BONEHAM SF8822MZ 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, this bushing features a 47/64-inch inside diameter and a 1-3/8-inch body outside diameter, providing close tool guidance in jig plate applications. The head-style design seats flush against the jig plate surface and locks in place using an LS-2 compatible lock screw. Manufactured from steel, the SF8822MZ delivers the wear resistance and dimensional stability required for repeatable production drilling. It is a renewable bushing, meaning it can be removed and replaced without replacing the liner bushing in the jig.

This bushing is used in drill jig assemblies across tool-and-die, machining, fabrication, and general metalworking environments. The slip-fixed configuration allows the bushing to be installed and removed from a fixed liner bushing using a quarter-turn motion, making it well-suited for operations that require multiple tool passes through the same hole location. The 1-3/8-inch length under head accommodates moderate jig plate thicknesses. Machinists, tool makers, and precision fabricators working with production jigs will find this bushing appropriate for high-repetition drilling cycles where consistent hole location is critical.

Key Features

• SF industry code slip-fixed design allows quarter-turn installation and removal from liner bushing
• 47/64-inch inside diameter with tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• 1-3/8-inch body outside diameter and 1-3/8-inch length under head for standard jig plate fitment
• Head outside diameter of 1-51/64 inches and 3/8-inch head height for positive seating against jig plate
• Steel construction provides wear resistance and dimensional stability in production drilling
• Renewable bushing design supports field replacement without disturbing the liner bushing
• LS-2 compatible lock screw secures the bushing against rotation during operation

Compatibility

Designed for use with LS-2 series lock screws and standard liner bushings accepting a 1-3/8-inch body outside diameter. Intended as an OEM-style renewable slip-fixed drill bushing for precision drilling jig assemblies conforming to SF industry standards.

Installation Notes

Installation is typically performed by tool makers or machinists during jig assembly or bushing replacement. Ensure the liner bushing and jig plate bore are clean and free of chips before seating the SF8822MZ. Engage the lock screw to the LS-2 port to prevent rotation during cutting operations. Always power down and lock out any associated machine spindle before servicing jig components.
