Boneham SP00008920 Slip-fixed Drill Bushing

Product Description

The BONEHAM SP00008920 is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Classified under industry code SF, this bushing installs by slipping into a drill jig liner and locking in place with a fixed-style head, keeping it secured during machining cycles. The inside diameter measures 29/32 inches and the body outside diameter measures 1.375 inches, with a body length under the head of 1.5 inches. The head outside diameter is 1-15/64 inches and the head height is 3/8 inches. This component is used by machinists, tool and die makers, and fixture builders working in precision metal fabrication environments.

Slip-fixed bushings of this type are commonly installed in drill jig fixtures used in production machining, aerospace component fabrication, and general metalworking shops. The SF designation indicates the bushing is intended for applications where the bushing must remain stationary during the full cutting operation, as opposed to renewable slip bushings that are rotated or exchanged between operations. This makes it well suited for single-tool-pass operations on production jigs where repeatability and hole location accuracy are critical.

Key Features

• SF industry code slip-fixed installation method for secure, stationary tool guidance
• Inside diameter of 29/32 inches for precise drill or reamer guidance
• Body outside diameter of 1.375 inches with 1.5 inch length under head
• Head outside diameter of 1-15/64 inches and head height of 3/8 inches
• Renewable bushing construction allows replacement without scrapping the jig liner

Compatibility

Designed as an OEM-style replacement or new-installation slip-fixed drill bushing for use in standard drill jig liners accepting a 1.375 inch body outside diameter.

Installation Notes

Installation is typically performed by machinists or toolmakers during jig fixture assembly or maintenance. The jig should be secured and free of cutting forces before removing or installing bushings. Proper press-fit or slip-fit engagement with the liner bore should be confirmed before use. Always verify that the bushing inside diameter matches the tool shank or guide diameter specified in the fixture design.
