Boneham SF3212HX Slip-fixed Drill Bushing 9/32 in Id Steel

Product Description

The BONEHAM SF3212HX is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features a 9/32 inch inside diameter and a 1/2 inch body outside diameter, with a 3/4 inch length under the head and a head outside diameter of 51/64 inch. The bushing is manufactured from steel and hardened to 60 to 65 HRC for long service life under repeated tool passes. The head-type design seats flush against the jig plate surface, and the inside diameter tolerance of plus 0.0001 to plus 0.0005 inch ensures consistent hole location accuracy. This part is installed by toolmakers, machinists, and jig-and-fixture technicians in production and maintenance environments.

The SF3212HX is suited for use in drill jigs where a renewable bushing must be retained in a fixed liner bushing. The slip-fixed style allows for quick removal and replacement when the bushing wears, without disturbing the liner. It is compatible with an LS-1 lock screw for positive retention during drilling operations. Typical applications include production drilling, reaming, and boring setups in metalworking shops and manufacturing facilities. The bushing conforms to ANSI standards, making it appropriate for use in tooling built to industry-standard specifications.

Key Features

• 9/32 inch inside diameter with a close tolerance of plus 0.0001 to plus 0.0005 inch for accurate tool guidance
• Steel construction hardened to 60 to 65 HRC for wear resistance under high-cycle drilling
• Slip-fixed installation method allows removal and replacement without disturbing the liner bushing
• Head-type design with a 51/64 inch head outside diameter and 1/4 inch head height seats positively against the jig plate
• LS-1 lock screw compatible for secure retention during operation
• Renewable bushing design extends fixture service life by allowing bushing swap-out without retooling

Compatibility

The SF3212HX is compatible with LS-1 lock screws and is designed for use with standard fixed liner bushings in drill jig assemblies built to ANSI specifications.

Installation Notes

Installation is performed by toolmakers or machinists during jig assembly or bushing replacement. The slip-fixed bushing is inserted into a previously installed liner bushing and locked in place with an LS-1 lock screw. Ensure the jig fixture is secured and the workpiece is properly clamped before drilling operations begin. Follow your facility safety procedures and applicable ANSI tooling standards when building or servicing drill jigs.
