Boneham SO00006638 Slip-fixed Bushing 5/16 in Id

Product Description

The BONEHAM SO00006638 is a slip-fixed drill bushing designed to guide cutting tools with precision during machining and fabrication operations. It features a 5/16 inch inside diameter and a 3/4 inch body outside diameter, with a 1-1/2 inch length under the head. The slip-fixed design allows the bushing to be installed and removed without special tooling while holding securely in the liner during use. This bushing is renewable, meaning the insert can be replaced independently of the liner, extending service life and reducing tooling costs. Machinists, tool-and-die makers, and fabricators working with jig and fixture setups are the primary installers.

This bushing suits production and prototype drilling, reaming, and boring applications where repeatable hole location is critical. The slip-fixed style is commonly used in jig setups where tool changes are frequent, allowing the operator to lift out the bushing, change the cutting tool, and reinstall without disturbing the fixture. It is appropriate for both light and medium-duty machining environments in job shops, maintenance departments, and manufacturing facilities.

Key Features

• Slip-fixed installation method allows quick removal and reinstallation during tool changes
• Renewable bushing construction supports in-place insert replacement without liner removal

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard drill jig liners accepting a 3/4 inch body outside diameter slip-fixed bushing per industry code SF.

Installation Notes

Drill bushings are installed and serviced by machinists and tool-and-die professionals. Ensure the liner bore is clean and free of burrs before seating the bushing. The bushing should seat flush and rotate to lock per the slip-fixed locking mechanism without excessive force. Inspect the bushing for wear at regular intervals and replace as needed to maintain hole-location accuracy.
