Boneham SF2022DH Slip-fixed Drill Bushing 0.1065 in Id Steel

Product Description

The BONEHAM SF2022DH is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to the SF industry standard, this bushing features an inside diameter of 0.1065 inches (Wire size No. 36) with a tight tolerance of +0.0001 to +0.0004 inches, a body outside diameter of 0.3125 inches (5/16 inch), and a length under head of 1-3/8 inches. Constructed from steel, it delivers the hardness and wear resistance required for repetitive production drilling. The headed design includes a head outside diameter of 35/64 inch and a head height of 1/4 inch. Installation and removal are handled by machinists and toolmakers working with drill jigs in metalworking and manufacturing environments.

The SF2022DH suits applications where tooling must be changed frequently at a single jig location. The slip-fixed design allows the bushing to be seated and locked in a liner bushing, then removed and replaced as drill bit sizes change during a multi-step operation. The counterbored bore and LS-1 compatible lock screw retention make this bushing appropriate for production jig setups requiring repeatable, accurate hole placement. It is a renewable bushing, meaning it can be swapped out when worn without replacing the liner.

Key Features

• SF industry-code slip-fixed design for use with liner bushings in multi-operation drill jigs
• Inside diameter of 0.1065 inches (No. 36 wire size) with tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction provides hardness and wear resistance for production drilling cycles
• Counterbored bore with LS-1 compatible lock screw compatibility for secure seating
• Renewable bushing design allows field replacement without disturbing the liner
• Headed configuration with 35/64 inch head OD and 1/4 inch head height for positive axial location

Compatibility

Compatible with LS-1 lock screws. Designed for use with standard liner bushings in SF-series slip-fixed drill jig applications per industry bushing standards.

Installation Notes

Installation is performed by machinists or toolmakers during jig setup or bushing replacement. The liner bushing must already be installed and properly seated in the jig plate before inserting the SF2022DH. Rotate and lock the bushing using an LS-1 compatible lock screw to prevent rotation or axial movement during drilling. Remove all cutting tools and ensure the jig is secured before servicing or replacing bushings.
