Boneham AM00001121 Slip-fixed Drill Bushing Sfm

Product Description

The BONEHAM AM00001121 is a slip-fixed drill bushing conforming to the SFM industry standard. It is used to guide cutting tools such as drills, reamers, and counterbores with precision in jig and fixture applications. The bushing features a 9.75 mm inside diameter and a 15 mm body outside diameter, with a 28 mm length under the head. The slip-fixed design allows the bushing to be inserted and locked into a jig plate liner without the need for press-fit installation, making it practical for production environments where bushings require periodic replacement. Machinists, tool-and-die makers, and fixture builders are the typical end users.

This bushing is suited for use in drill jig plates and modular fixturing systems in both production machining and job-shop environments. The SFM designation identifies it as a slip-fixed style that seats into a standard headless or headed liner already installed in the jig plate. It is commonly specified when multiple operations are performed at a single hole location, requiring bushing changes between operations without disturbing the liner. The renewable design supports repeated installation and removal across production runs.

Key Features

• Slip-fixed installation method allows bushing removal and replacement without press or heating equipment
• SFM industry standard designation ensures dimensional interchangeability with compatible liners and jig components
• 9.75 mm inside diameter for precise tool guidance
• 15 mm body outside diameter for secure seating in the liner bore
• 28 mm length under head provides adequate tool guidance depth for typical jig plate thicknesses
• Renewable bushing construction supports multiple replacement cycles

Compatibility

Designed as an OEM-style replacement and standard production component for drill jig fixtures requiring SFM-series slip-fixed bushings with a 9.75 mm ID and 15 mm body OD.

Installation Notes

Installation and removal are performed by machinists or tool-and-die technicians using standard jig bushing removal tools. Ensure the mating liner bore is clean and free of chips or burrs before seating the bushing. The locking mechanism must be fully engaged before beginning any cutting operation. Always de-energize or lock out machine spindles before changing bushings in an active fixture.
