Boneham SF6412LR Slip-fixed Drill Bushing 17/32 in Id

Product Description

The BONEHAM SF6412LR is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to the SF industry code, it features a 17/32 inch inside diameter and a 1 inch body outside diameter, with a head outside diameter of 1-27/64 inches and a head height of 3/8 inches. The body length under the head measures 3/4 inch. Constructed from steel hardened to 60-65 HRC, this bushing delivers the wear resistance required for repetitive drilling operations. Licensed machinists, toolmakers, and fixture builders install this type of component as part of precision drill jig assemblies.

The SF6412LR is used in industrial and production machining environments where a renewable bushing is needed in a fixed liner. The slip-fixed design allows the bushing to be removed and replaced without disturbing the liner, making it well suited for jigs that see multiple tool changes or varying drill sizes across production runs. It is compatible with an LS-2 lock screw for secure retention during operation. This bushing is appropriate for both light and medium-duty drilling, reaming, and similar guided tooling operations.

Key Features

• SF-code slip-fixed design allows removal and replacement without liner disturbance
• 17/32 inch inside diameter with a tolerance of +0.0001 to +0.0005 inches for close-tolerance tool guidance
• Steel construction hardened to 60-65 HRC for extended wear life
• Renewable bushing construction supports tool changes across production runs
• LS-2 compatible lock screw slot for positive retention in the liner
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed for use with LS-2 compatible lock screws and standard SF-series fixed liner bushings per ANSI specifications. Fits jig and fixture assemblies requiring a 1 inch body outside diameter slip-fixed renewable bushing.

Installation Notes

Installation is performed by toolmakers or machinist personnel as part of drill jig assembly or maintenance. Ensure the mating liner bushing bore is clean and free of chips before inserting the SF6412LR. Engage the LS-2 lock screw to secure the bushing against rotation and axial movement during drilling. Follow applicable shop safety procedures and de-energize any powered equipment before servicing fixtures mounted to machines.
