Boneham CB00001132 Slip-fixed Drill Bushing 3/16 in Id

Product Description

The BONEHAM CB00001132 is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to ANSI standards from hardened steel, this head-type bushing features a 3/16 inch (0.1875 inch) inside diameter with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate, repeatable hole location. The 5/16 inch body outside diameter and 3/4 inch length under the head suit it for moderate-depth drilling setups. It is installed and serviced by toolmakers, machinists, and production engineers working with drill jigs in manufacturing and precision fabrication environments.

This bushing is used in slip-fixed configurations where the bushing must be removable during operation but locked in place during the cutting cycle. The renewable design allows the bushing to be replaced independently of the jig plate, extending the service life of the fixture. Compatible with LS-1 lock screws for positive retention during use, it is well suited for production drilling, reaming, and similar guided-tool operations on steel, aluminum, and other structural materials in both job-shop and high-volume manufacturing settings.

Key Features

• Slip-fixed (SF) bushing industry code — removable and lockable during tool changes
• Hardened steel construction, 60 to 65 HRC for long service life under repeated drilling cycles
• Inside diameter tolerance of +0.0001 to +0.0004 inches for tight, repeatable tool guidance
• Head-type design with 35/64 inch head outside diameter and 1/4 inch head height for positive seating in the jig plate
• Renewable bushing — replaceable without scrapping the jig plate
• LS-1 lock screw compatible for secure retention during the cutting operation

Compatibility

Designed as an ANSI-standard slip-fixed drill bushing compatible with LS-1 lock screws. Fits standard jig plates machined to accept SF-series head bushings with a 5/16 inch body outside diameter.

Installation Notes

Installation is typically performed by a toolmaker or machinist during jig assembly or bushing replacement. Press the bushing into the counterbored jig plate hole by hand or with a arbor press — do not hammer directly on the head. Secure with an LS-1 lock screw before beginning any cutting operation. Verify inside diameter clearance is appropriate for the tool shank diameter before committing to a production run.
